Description

Method for automatic guidance of the motor vehicles on roads and automatic transport system

Field of the invention

The invention concerns driverless motor vehicles, which are steered by a computer using an autopilot method along a predetermined pathway. The invention is earmarked for the automotive industry and transportation.

Description of the prior art

Permanent increase of the number of motor vehicles is steering the mankind towards an ecological catastrophe due to the CO₂ emissions released into the atmosphere. There are attempts to reverse this unfavorable development. Hydrogen motors have been already developed, but the automotive industry did not take up on their production due to operational costs several times higher in comparison to classical fossil fuel engines. The problem with hydrogen filling stations also remains an issue.

Electric motors for cars have also been developed; however, their use is minimal today due to the electric battery weight and a relatively short range under 200 km. The hybrid engines only provide a partial solution of the emission problem as they use fossil fuels too.

With the rise of road traffic, mortality and injuries in road accidents as a consequence of driver' s failure increase proportionally.

There have been permanent attempts to create automatic traffic systems with driverless computer steered vehicles. Particularly, the systems using vehicles with electric motors only. It will have considerable impact on the environment, climatic changes, traffic safety and other aspects of the transport system. A lot of driverless cars and car steering systems have been invented. Known are for example vehicle steering systems with permanent tracks, with built-in electric guiding wire, light reflection, radio guidance system, guidance by fluorescent material on the pathway or GPS satellite controlled navigation, etc. Such systems are described as prior art in the patent US 3935922. These driverless steering systems are usable only for special applications and are not appropriate for regular city transport.

The status of art also recognizes driverless car systems for regular roads using navigation by optical cameras and sensors over-viewing traffic situation and passing on information to the board computer steering the motor vehicle. Vehicles of this type are expensive and today used only as experimental models. The most famous car of this type is "Boss" by General Motors, using a combination of radar, optical sensor LIDAR and GPS visualization systems. During the 2007 tests within the city limits it reached an average speed of 15 km/h. It is obvious that this type of car is still slow and it do not reduce the number of road accidents and production of greenhouse gases.

Patent US 200800047778 contains a navigation and steering system based on GPS navigation. The communication between the vehicle and GPS satellites is performed on long distances, which leads to slow vehicle reaction times. Due to this problem this type of navigation system is recommended only for agricultural machinery.

There are also cars using electromagnetic guidance systems described in patents US 4006790, US 4855656, US 4344498, US 5175480, enabling to guide a driverless car along electric cables built into the road. This method however does not cover all aspects of routine automatic transport system such as: maintenance of a safety distance between cars, correct turning at intersections, automatic parking, electric energy supply during long distance travels, etc.

From the prior art, we know electrically powered vehicles, where electric current to the motor is supplied from batteries. A disadvantage of the electro-mobiles is their short range, not exceeding 200 km despite using a large amount of batteries, which in addition have a considerable weight. The real need of electro-mobiles is underlined by the "Better Place" project in which the Israeli government approved a change of transport system in the whole country to electro- mobiles. The project implementation is slated for 2011, when the first electro-mobiles by Renault and Nissan should be delivered to the market. Electro-mobiles should have a very economical consumption of only a 1.6 liters of petrol equivalent per 100 km. The disadvantage of the "Better Place" system is a need to stop at the exchange stations, where discharged batteries have to be exchanged for new. Within the project, 500,000 exchange stations should be built in Israel, which is capital intensive.

Known are also hybrid engines for motor vehicles, but they solve the emission problem only partially as they still use fossil fuels for longer distances.

Vehicle actuation also uses hydrogen fuel cells. Operation of such vehicles is still expensive and problematic, because a network of hydrogen fuel stations is non-existent so far.

The existing problems involving mainly slow reaction times of driverless car steering, which is attributable to either a huge amount of information coming from the optical systems, radars and sensors in the vehicles of "Boss" type, or by enormous distances between vehicle and satellites in the GPS navigation triggered a need to create a system, which would allow using the driverless cars in a computer controlled transport system on the proposed type of roads. This will establish a computer controlled order in the road traffic without emissions and traffic accidents.

The result of this effort is the method for automatic guidance of the motor vehicles on the roads and automatic transport system described below.

Merit of the invention

The above described defects are in principle eliminated by the invented method for automatic guidance of the motor vehicles on roads, which operates on the assumption that only driverless cars steered by a board computer will be present on road. Considered are electro-mobiles with electric motors. In this invention, the term vehicle refers to a passenger car of the automatic taxi type of different sizes, buses of different sizes, lorries, motor vehicles of different types and sizes and special motor vehicles. The board computer controls vehicle guidance, movement parameters and vehicle actuator in interaction with the telecommunication data exchange either with the central computer and/or with the other locally present board computers of surrounding vehicles. The vehicle guidance is based on an optical imaging of the guideline present on or in the surface of the road by the optical guideline imaging device fixed on the vehicle. Optical imaging device with a CCD camera is fixed under the floor in the front part of the vehicle exactly on the longitudinal vehicle axis. The board computer steers the wheels according to the guideline image so that the vehicle follows the guideline placed on the road. The board computer evaluates all deviations between the guideline image and the vehicle axis and transfers a command to the steering device to turn wheels accordingly so that the vehicle axis and its movement direction are positioned exactly over the guideline. For safety reasons, the car is equipped by a backup optical imaging device with a CCD camera placed behind the first optical guideline imaging device. In case of any malfunction of the first optical imaging device of the guideline, the vehicle will be steered by the backup optical imaging device of the guideline.

The board computer controls vehicle movement parameters by optical scanning of the info-line present on or in the surface of the road by the info-line optical imaging device fixed on the vehicle. In this case, the info-line comprises a one dimensional bar code. The bar code on any particular part of the road comprises coded information about preset vehicle speed and/or its actual position and/or radius of the road curvature and/or guideline splitting on the intersection and/or stopping point at an intersection or a parking place and other necessary information. This coded information is scanned by the first info-line optical imaging device. The second info-line optical imaging device comprising two CCD cameras transfers information to the board computer steering the vehicle where for any reason the guideline is not scanned or the information on the guideline position is missing in the board computer or where the bar code was incorrectly read by the first optical imaging device. In an alternative version, the info-line can also be in the form of a 2D (two dimensional) code comprising more information.

The board computer controls the vehicle movement parameters, which are usually derived from optical scanning of the info-line present on or in the surface part of the road by at least one radiofrequency sensing device fixed on the vehicle. In this case, the info-line represents a radiofrequency code contained in the radiofrequency chip. The radiofrequency code on any particular part of the road comprises coded information on the preset vehicle speed and/or its actual position and/or radius of the road curvature and/or guideline splitting on the intersection and/or stopping point on an intersection or a parking place and other necessary information.

According to the information from the bar code, the board computer software modifies vehicle speed, by the steering device turns the wheels so that the vehicle follows the guideline, traces the car movement on the map, ensures proper vehicle turning to the desired direction at intersections and stops the vehicle at intersections or at an intended parking place. The bar code length along the info-line depends on the preset vehicle speed in the specific road section. Parts of the info-line which share the same line code are called info- line sectors. In road sections where vehicles accelerate or decelerate, the length of the bar code sectors will adequately increase or decrease respectively.

An important feature of the automatic driverless car system is the communication of the vehicle board computer via telecommunication system e.g. GSM with other locally present board computers of the surrounding vehicles to solve immediate traffic issues. Each board computer knows its instant location (address) on the road map. It continually transmits the information on its instant location (address) to the vehicles driving in front, behind or in the neighbouring lane. All vehicles travel in the given lane at the same - preset speed. Each board computer maintains a safety distance from other vehicles for cases of acceleration, deceleration or even hard braking in dangerous situations. The vehicle brakes in interaction with the surrounding vehicles to maintain a safe distance between them. The board computer calculates adequate speed and time for a vehicle change lanes to be safe and prevent collisions with other vehicles. The same algorithm will be used at an intersection, where information from the info-line will be used to follow the selected guideline.

Due to safety reasons vehicles are equipped with a front scanner and side scanners to prevent collisions should an unexpected obstacle emerge in the traffic lane such as a human or animal. In such situation, the vehicle stops immediately. The reaction time of the board computer is considerably shorter than the human reaction times . The vehicle brakes in interaction with the surrounding vehicles to maintain a safety distance between them. In the traffic system with computer controlled vehicles measures will be taken to avoid presence of humans or animals on the road. The board computer is also equipped with a self-diagnostics system to identify malfunctions on a vehicle. In the case of a serious malfunction, the driverless vehicle will carry passengers to the nearest parking place and ask them to get off the car and then it will move to the nearest service point.

In the transport system contained herein involving motor vehicles steered by the board computers, the essential component is a stationary central computer, which is receiving information on instant position (address) of each vehicle on the transport system map. The central computer gives commands to all vehicles in the system, maintains traffic flow and solves emergency situations. The central computer commands are obligatory for each board computer of any vehicle in the system.

One of the features of the invented automatic transport system is that the board computer controls parameters of at least one electric motor and/or electric battery in the vehicle. In the road sectors not allowing installation of electric traction by which the electric motor could be powered, the board computer powers the electric motor from batteries. This solution will be used mainly in urban areas. To the contrary, on roads with long sections free of intersections typical for highways, or roads connecting villages and the like, the board computer controls the electric power flow through at least one electric power bus fixed on the vehicle from at least one section of the electric traction located on an elevated part of the road or placed on the road barrier.

The first basic feature of the invented automatic transport system is a vehicle adapted for the movement on a modified road. The second basic feature is the modification of the road for the movement of driverless vehicles.

The vehicle comprises at least one electric motor and at least one optical and/or radiofrequency info-line imaging device. Each is oriented either optically and/or by way of radiofrequency towards the road. At least one power bus is oriented towards the road and/or the road barrier. Further, it comprises a board computer connected to at least one optical guideline imaging device and at least one optical and/or radiofrequency info-line imaging device, and on the output, it is connected to the active parts of the power bus, steering device and the electric motor. The board computer is further connected via a mobile telecommunication facility to the stationary central computer and/or other locally present board computers of the surrounding vehicles.

The optical guideline imaging device and at least one optical and/or radiofrequency info-line imaging device in the vehicle contain a CCD camera. To the contrary, the radiofrequency info-line imaging device comprises a radio receiver with an antenna. Because the guideline and the info- line scanning has to be functional and reliable also at night, a lamp is installed in front of the optical guideline imaging device and/or the optical info-line imaging device. Also, a cleaning apparatus comprising a mechanical remover and/or vacuum cleaner and/or ventilator could be installed in front of the optical guideline imaging device and/or the optical info-line imaging device.

The road is on or inside its surface equipped by at least one guideline and at least one info-line and at least one partial and/or full electric traction installed on the elevated part of the road or on the road barrier.

The guideline consists of a track with a longitudinal contrast line in the middle.

The info-line consist of sectors of a bar or 2 D code comprising traffic parameters: the preset vehicle speed and/or its actual position and/or radius of the road curvature and/or guideline splitting at an intersection and/or stopping point at an intersection or a parking place and another necessary information.

The info-line consist of a radiofrequency chip containing a radiofrequency code comprising traffic parameters: the preset vehicle speed and/or its actual position and/or radius of the road curvature and/or guideline splitting at an intersection and/or stopping point at an intersection or a parking place and another necessary information.

The advantages of the method for automatic guidance of motor vehicles on roads and the automatic transport system are obvious from the visible consequences. It can solve the pressing issue of atmosphere pollution by emissions from motor cars, which thereafter cause a greenhouse effect and trigger serious climatic changes on Earth. The invented transport system allows using electrically powered vehicles whereby emissions from cars are reduced to the zero. The invented transport system will help to solve many problems such as climatic changes, shrinking oil resources and rising petrol prices; it will solve traffic issues such as traffic jams in cities or on highways, parking issues, etc. The problem of toady's electro cars is their short range. The invented transport system solves this problem by introducing electric traction installed on the elevated part of the road and/or the road barrier. By doing this, we achieve unlimited vehicle range within the transport system. At the same time, it is necessary that the vehicles within the system with electric traction be controlled by computers, which are driving more precisely and without the faults often committed by drivers.

Further, a very important asset of the invented transport system will be a considerable decrease of road accidents, which are usually caused by faults and improper driving of drivers. The social and economic effect of the decrease of mortality and other road accidents will be vast and unambiguously positive.

The invented transport system can replace all present all kinds of terrestrial transport. For example, railway transport will become non effective and comfortless. The passenger will not need to travel to the railway station, wait for the train to transport him to the railway station in another town, form which he has to travel to the chosen address by another type of transport. The intercity taxi described herein will arrive in any moment in front of his house. It will transport him fast and comfortably to the chosen destination in another town. The existing railway corridors could be rebuilt to serve as fast arteries of the invented transport system. Construction and maintenance of the roads within the invented transport system will be much cheaper than the construction and maintenance of the railway tracks. The invented system can also effectively and profitably utilize existing metro lines or tramway corridors in the cities .

Description of the examples

It is understood that particular applications of the invention are presented for illustration and not for limitation of the technical solutions. The specialists, familiar with the prior art will find, or will be able to find within routine experiments many equivalents to the particular solutions of this invention. Also, such equivalents will fall under the claims presented in the invention. For the experts familiar with the prior art, it will not be difficult to identify proper dimensions, choice of materials and construction designs for the application of the invention, therefore such details were not disclosed.

Example 1

In this example of particular application of the invention, the method is described for automatic guidance of the motor vehicles JL on the roads 4_ in the case of supplying power from the battery Jl_3 which is shown in Fig.l. Only driverless vehicles JL ^are considered moving on the roads _4 and controlled by the board computer 9_. Considered are vehicles JL equipped with electric motors _2. The board computer _9 controls the steering of the vehicle JL movement and traction parameters in collaboration with the mobile data exchange either with the stationary central computer Yλ_ and also with the other locally present board computers _9 of the surrounding vehicles JL. The steering of the vehicle _1 is derived from the optical scanning of the guideline _β situated on the surface of the road _4 by the optical guideline _6 imaging device 3.1 fixed on the vehicle _1. The optical imaging device 3.1 with a CCD camera is fixed under the floor in the front part of the vehicle _1 exactly on the longitudinal vehicle 1_ axis. The board computer 9_ steers the wheels according to the guideline _β image by means of a steering device _1_(3 so that the vehicle _1 follows the guideline _6 placed on the road 4_. All deviations between the guideline 6_ image and the vehicle 1_ axis are evaluated by the board computer _9 and a command is transferred to the steering device l_0 to turn wheels accordingly so that the vehicle 1_ axis and its movement direction get exactly over the guideline _6. For safety reasons, the car 1 is equipped by a backup optical guideline _6 imaging device 3.1 with a CCD camera placed behind the first optical guideline imaging device 3.1. In case of any malfunction of the first optical imaging device 3.1 of the guideline _β, the vehicle 1_ will be steered by the backup optical imaging device 3.1 of the guideline _β.

The board computer _9_ controls vehicle 1_ movement parameters by optical scanning 3.2 of the info-line 1_ present on or in the surface of the road A_ by the info-line optical imaging device 3.2 fixed on the vehicle 1_. The Info-line 1_ comprises a bar code. The bar code on any particular part of the road comprises coded information on the preset vehicle _1 speed, its actual position, radius of the road curvature, guideline _6 splitting at intersections, stopping point at an intersection or a parking place and other necessary information. This coded information is scanned by the first info-line optical imaging device 3.2. The second info-line optical imaging device 3.2 comprising two CCD cameras transfers information to the board computer _9 steering the vehicle 1 in this case, when due to any reason the guideline _5 is not scanned or the information on the guideline _6 position in the board computer _9 is missing, or where the bar code was incorrectly read by the first optical imaging device 3.1.

According to the information from the bar code, the board computer _9 software modifies the vehicle JL speed, by way of the steering device JLO_ turning the wheels so that the vehicle JL follows the guideline _6, traces the vehicle JL movement on the road map, ensures proper vehicle JL turning to desired direction at an intersection and stops the vehicle JL at an intersection or the intended parking place. The bar code length along the info-line 1_ depends on the preset vehicle JL speed in the particular road section. Parts of the info-line 1_ sharing the same bar code are called info-line 1_ sectors. In the road sections where vehicles accelerate, or decelerate, the length of the line code sectors will adequately increase or decrease respectively.

An important feature of the automatic driverless car system is the communication of the vehicle JL board computer 9_ via the telecommunication system JLJL e.g. GSM with the other locally present board computers _9 of the surrounding vehicles JL to solve actual traffic situations. Each board computer 9_ knows its instant location (address) on the road map. It continually transmits the information on its instant location (address) to the vehicles JL driving in front, behind or in neighbouring driving lane. Based on the information on the movement of the surrounding vehicles JL, the board computer 9_ maintains a safety distance from the vehicle JL driving in front of it. All vehicles JL travel in the given lane at the same - preset speed prescribed by the info-line 1_. Each board computer 9_ maintains a safety distance from other vehicles JL also in the case of acceleration, deceleration, or even hard breaking in dangerous situations. The vehicle JL brakes in collaboration with the surrounding vehicles JL, to keep a safe distance between them. The board computer 9_ also calculates adequate speed and time for a vehicle 1_ to change lanes so that it is safe and collisions with other vehicles 1_ are prevented. The same algorithm will be used at intersections where the information from the info-line 1_ will be used to follow a selected guideline _β.

Due to safety reasons, the vehicle 1_ is equipped by a front scanner and side scanners to prevent collisions in case unexpected obstacles such as humans or animals are on the road. In such situations, the vehicle 1_ stops immediately. The reaction times of the board computer 9_ are considerably shorter than the human reaction times. The vehicle 1_ brakes in interaction with the surrounding vehicles 1_ to keep a safe distance between them.

The board computer _9 is equipped also with a self- diagnostics system monitoring defects on the vehicle 1_. In the case of serious defect, the driverless vehicle 1_ will carry passengers to the nearest parking place, ask them to get off the car, and then it will move to the nearest service point.

The invented automatic transport system operates on motor vehicles 1_ steered by the board computers _9 with the essential component being a stationary central computer 2L2_, which is getting information on instant position (address) of each vehicle 1_ on the transport system map. The central computer 1J2 gives commands to all vehicles _1 i-ⁿ the system, maintains traffic flow and solves emergency situations. The central computer 1_2 commands are obligatory for each board computer _9 of any vehicle 1_ in the system.

Road _4 sections not allowing installation of electric traction 8_ to power_the electric motor 2_, the board computer 9_ could power the electric motor 2_ from batteries L3. This kind of operation will be used mainly in urban areas. Example 2

This example of particular application of the invention describes the second method for automatic guidance of the motor vehicles 1. on the roads _4 in the case of supplying power from electric traction 8_. The characteristics from Example 1 are identical, but they are enhanced by new ones. On roads _4_ with long sections without intersections, or exits typical for highways, or roads _4 connecting villages and the like, the board computer _9 controls electric power flow through at least one power bus _5 fixed on the vehicle _1 from at least one section of the electric traction _8 located on elevated part of the road _4.

Alternatively, in this method for automatic guidance of the motor vehicles 1_ on the roads _4_, the board computer 9_ controls electric power flow through at least one power bus 5_ fixed on the vehicle 1_ from at least one section of the electric traction 8_ located on or in the road barrier 14.

Within practical operation of driverless vehicles 1 controlled by a board computer _9, it is possible in accordance to the situation to combine supply of power from batteries T3_ with taking power from the electric traction _8.

Example 3

This example of particular application of the invention describes the motor vehicle 1_ ^{as one} part of the automatic transport system, which is modified for the movement on the road _4 as it is shown in Fig. 1., the motor vehicle _1 comprises one electric motor 2_, two optical guideline imaging devices 3.1 and two optical imaging devices 3.2 for the info- line 2 scanning. Each of them is oriented towards the road 4_. The vehicle 1_ comprises an electric power bus _5 oriented towards the road _4. Further, it comprises a board computer _9 connected to an optical guideline imaging device 3.1, info- line optical imaging device 3.2 and connected to the action units of the power bus 5_ steering device _10_ and electric motor 2_. The board computer _9 is by mobile telecommunication system 11 connected with a stationary central computer \2_ and with the other locally present board computers _9 of the surrounding vehicles JL. The optical guideline imaging device 3.1 and the optical info-line imaging device 3.2 of the motor vehicle JL comprise CCD cameras. A lamp is placed in front of the optical guideline imaging device 3.1 and the optical info-line imaging device 3.2 of the motor vehicle JL. A cleaning apparatus comprising a mechanical remover and a ventilator is installed in front of the optical guideline imaging device 3.1 and the optical info-line imaging device 3.2 of the motor vehicle JL.

In the case the electric motor 2_ in the vehicle JL is using other voltage as the voltage in the electric traction _8, the vehicle JL would comprise a voltage converter.

Example 4

This example of particular application of the invention describes the motor vehicle JL as one part of the automatic transport system modified for the movement on the road _4, expanding the application under Example 3. The motor vehicle JL can also comprise an auto-diagnostic device, which is not obligatory. In another alternative, a cleaning apparatus comprising a mechanical remover and a ventilator is installed in front of the optical guideline imaging device 3.1 and the optical info-line imaging device 3.2 of the motor vehicle JL. In another alternative, the vehicle JL is equipped with four electric motors, one on each wheel. In another version, the info-line imaging device 3.2 could be replaced by a radiofrequency info-line imaging device 3.3 with a radio receiver with antenna.

Alternatively, the vehicle JL can comprise two power buses 5_ oriented towards the electric traction _8_ located on the elevated part of the road 4_, provided the conditions on the road allow such arrangement. Example 5

This example of particular application of the invention describes one implementation of the road _4 as a second part of the automatic transport system, applicable in the urban area, which is modified for the vehicle 1_ movement as shown in Fig. 2. The road surface _4 is equipped by one guideline _β and one info-line 1_. The guideline _6 consists of a track with a longitudinal contrast line in the middle. The info-line 1_ consists of the sectors of a bar code comprising movement parameters: the preset vehicle 1_ speed, its actual position, radius of the road curvature, guideline _6 splitting at an intersection, a stopping point at an intersection or a parking place and the other necessary information. The guideline _6 and/or one info-line 1_ could be made in the form of a paint coat or a stencil by means of pattern. They could be manufactured also as plastic or metallic lines glued onto the road 4_ or by the other suitable method of attachment such as anchoring units. The line surface could be dressed by transparent hard varnish.

Example 6

This example of particular application of the invention describes one implementation of the road _4 as a second part of the automatic transport system, applicable in the urban area, which is modified for the vehicle 1_ movement, extending the implementation from Example 5. The road _4 is in or on its surface equipped by the info-line 1_, which consists of the sectors of a line code comprising movement parameters described above. As another alternative, the road surface 4_ is equipped by the info-line 1_, which consists of radiofrequency chips containing a radiofrequency code comprising traffic parameters described above. In another alternative, the road surface 4 is equipped by several guidelines _6 and several info-lines 7. It should be clarified that in scope of the invented integrated automatic city transport system all kind of vehicles JL as passenger cars of the automatic Taxi type of different sizes, buses of different sizes, lorries, special motor vehicles are steered by board computers 9_ and actuated by electric motors. Motor vehicles JL travel down the guideline §_ by the same - preset speed prescribed by the info-line J7. Passenger vehicles JL are of the Taxi type for two, four or more passengers. The vehicles JL will be parked in parking stands where they will recharge their batteries JL_3_ from the electric power point built-in the parking stand from electric traction 8_ located under the vehicle JL. Batteries JLJ3 allow the vehicle to drive a distance inside the city of maximum 20 - 50 km. When a passenger comes to the vehicle JL, the door opens. Passengers get on and on the board computer 9_ control console inputs the desired destination. After inserting a credit card, the board computer calculates the traffic fee. The door closes and with the road free, the Taxi moves from the parking stand to the acceleration lane or directly to the driving lane where it will travel at a preset speed, maintaining communication with the surrounding vehicles JL and maintaining a safety distance between them. This way passengers are carried via an optimal route according to the city electronic map to the desired destinations. After passengers get off, the vehicle JL is ready to transport other passengers. This solves parking problems. The traffic in the town is smooth and fast due to the control and regulation by a stationary central computer 12. The speed in the town is matched to the character of the roads, in particular sections it can reach up to 100 krα/h. If there is no vehicle JL in a parking place, the passenger could call it by a mobile telephone. No driving licence is necessary for passengers.

Cargo vehicles JL₁. buses and special vehicles operate on a similar principle. A cargo vehicle JL of the corresponding size will come upon a phone request to a loading place. After loading, the customer will provide the board computer 9_ with the address to which the goods should be transported to. He will insert the credit card to which the transport fee will be debited. The vehicle 1_ will transport the goods to the required destination, where the recipient will unload it. The vehicle 1_ is ready for further transport. The stationary central computer _12_ will dispatch it to the required location.

Special vehicles, such as ambulances, police cars, fire brigade cars, service and other vehicles will have the option of manual steering to be able to exit the computer controlled transport system. Also other cargo or passenger vehicles, which need to drive outside the invented transport system e.g. to building sites, etc. will be equipped with manual steering. When a vehicle equipped with the manual steering will arrive to the invented automatic transport system, its steering will be taken over by the board computer 9.

Example 7

This example of particular application of the invention describes the second implementation of the road £ as a second part of the automatic transport system, applicable in the intercity area, modified for the vehicle 1. movement as shown in Fig. 3. The essential part of the road _£ is described in Example 5 and alternatively also in Example 6. A distinctive feature is that it comprises at least one partial or full electric traction _8 located on elevated parts of the road _4 and/or in the road barrier 14.

It should be clarified that the invented integrated intercity transport system is a proper solution for inter city transport. The guidelines _6 and info-lines 1_ are painted onto the highways driven by passengers or cargo vehicles _1. Passenger transport is covered by Intercity Taxi adapted for high speed driving.

Passengers get on and put in the desired destination into the board computer _9 control console. Passengers in the city will order an Intercity Taxi to their individual addresses. After boarding, passengers will input the address in the target city and pay by a credit card. The intercity Taxi will carry passengers to their required addresses via optimal routes. On roads 4_ with long sections without intersections, the electric traction _8 is located on the road barrier 14, which feeds the vehicle 1. power through the electric power bus _5 in form of a trolley located on the side of the vehicle 1_ for its movement and also for battery 1_3 recharge.

The right lane of a four-lane highway is earmarked for heavy motor vehicles 1_ such as lorries or buses driving at lower speed. The left lane will be reserved for passenger and lighter cargo vehicles 1_ travelling at high speed. All vehicles 1_ will travel in the given lane at same - preset speed and maintain safety distances between them. In the middle of the highway there will be the usual median separating barrier 3^4. For safety reasons, traffic lanes are separated by lower barriers \Λ_, which will keep the vehicle 1 within the lane in emergency cases until halt. The transition lanes from slower to faster lane are located after each intersection. An acceleration lane, in which the vehicle 1 increases its velocity to the fast lane is located between slow and fast lane. At the end, the accelerating lane it will change to the high speed lane. Similar process will occur before an intersection at which the vehicle 1_ will turn.
