Description

Die Erfindung bezieht sich auf ein Transport- und Verkehrsleitsystem mit einem Tourenrechner zur Tourenplan­optimierung beim Fuhrunternehmer und mit Lieferfahrzeugen, die mit einer Leit- und Informationseinrichtung ausgerüstet sind, sowie mit einem Verkehrsleitrechner einer Kommune für ein Leit- und Informationssystem für den Individualverkehr.The invention relates to a transport and traffic control system with a tour computer for optimizing the tour plan for a haulage contractor and with delivery vehicles equipped with a control and information device, and with a traffic control computer of a municipality for a control and information system for individual traffic.

Es ist bekannt, zur Tourenoptimierung für den Güterverteil­verkehr computergestützte Systeme zu verwenden. Ein bekanntes System zur Fuhrparksteuerung, z.B. TRAFIC-X, gestattet für eine Transportoptimierung eines Fuhrparks mittels eines Touren­rechners alle Gegebenheiten von Kunden, Fuhrpark, Lager und Strecken in die Tourenplanung einzubeziehen. Für die Wege­planung beruht die Tourenoptimierung jedoch lediglich auf Luftlinienentfernungen zwischen den Auslieferungslagern und den Kunden. Mit den bekannten Systemen ist eine straßennetzab­hängige und situations- bzw. verkehrsabhängige Fahrrouten­planung nicht durchführbar.It is known to use computer-aided systems for route optimization for the distribution of goods. A known system for fleet management, e.g. TRAFIC-X allows for the optimization of the transport of a fleet by means of a tour computer to include all circumstances of customers, fleet, warehouse and routes in the tour planning. For route planning, however, route optimization is only based on air line distances between the distribution centers and the customers. With the known systems, a route network-dependent and situation-dependent or traffic-dependent route planning cannot be carried out.

Es ist auch ein Verkehrsleit- und Informationssystem bekannt, bei welchem die einzelnen Fahrzeuge individuell von einem jeweiligen Ausgangsort zu eingebbaren Zielorten geführt werden können. Bei dem bekannten Leit- und Informationssystem für den Individualverkehr ist neben einer Verkehrs- und Informations­leitzentrale eine entsprechende Infrastruktur erforderlich. Verfahren zur Verkehrserfassung und -lenkung sind beispiels­weise in den europäischen Patentschriften 021 060, 025 193 und 029 201 beschrieben und unter dem Namen ALI-SCOUT bekannt.A traffic management and information system is also known, in which the individual vehicles can be guided individually from a respective starting point to destinations that can be entered. In the known control and information system for individual traffic, a corresponding infrastructure is required in addition to a traffic and information control center. Methods for traffic detection and control are described, for example, in European Patents 021 060, 025 193 and 029 201 and are known under the name ALI-SCOUT.

Aufgabe der Erfindung ist es, ein integriertes Transport- und Verkehrsleitsystem vorzuschlagen, welches erlaubt, beide Systeme miteinander zu verbinden und Einrichtungen sowie Maßnahmen hierfür anzugeben.The object of the invention is to propose an integrated transport and traffic control system which allows the two systems to be connected to one another and to specify facilities and measures therefor.

Diese Aufgabe wird bei einem oben erläuterten Transport- bzw. Verkehrsleitsystem mit folgenden Merkmalen gelöst:

  • a) In dem Leit- und Informationssystem ist am Verkehrsleit­rechner ein Transportroutenrechner angeschlossen, dem eine Datenübertragungseinrichtung nachgeschaltet ist,
  • b) die im Leit- und Informationssystem in Form von digitali­sierten Straßennetzbeschreibungen eingebbaren Netzdaten und aktuelle Verkehrsdaten werden in Transportroutenrechner ver­arbeitet und aufbereitet,
  • c) zumindest ein Tourenrechner ist über eine Übertragungs­einrichtung mit dem Transportroutenrechner verbindbar,
  • d) die vom Transportroutenrechner zum Tourenrechner übertragenen, speziellen Leit- und Informationsdaten werden im Tourenrechner mit den Tourenplandaten verknüpft und hieraus werden optimale Fahrrouten mit Name, Adresse, Koordinaten und der Reihenfolge der zu beliefernden Kunden für ein jeweiliges Lieferfahrzeug berechnet,
  • e) an den Tourenrechner sind über eine Bakenanschlußeinrichtung und eine Bakenelektronik eine oder mehrere Ladehofbaken ange­schlossen,
  • f) mittels der Ladehofbaken werden vom Tourenrechner an die aus dem Ladehof ausfahrenden Lieferfahrzeuge die jeweiligen Fahr­routendaten sowie zugehörige Leitvektorketten übertragen,
  • g) in den Lieferfahrzeugen wird mittels des bekannten Leit- und Informationssystems an der Anzeigeeinrichtung der Leit- und Informationseinrichtung die situationsabhängige Zielführung zum Kunden angezeigt.
This problem is solved in a transport or traffic control system explained above with the following features:
  • a) In the control and information system, a transport route computer is connected to the traffic control computer, which is followed by a data transmission device,
  • b) the network data and current traffic data that can be entered in the control and information system in the form of digitized road network descriptions are processed and processed in transport route computers,
  • c) at least one tour computer can be connected to the transport route computer via a transmission device,
  • d) the special guidance and information data transmitted from the transport route computer to the tour computer are linked to the tour plan data in the tour computer and from this optimal route with name, address, coordinates and the order of the customers to be supplied for a respective delivery vehicle are calculated,
  • e) one or more loading yard beacons are connected to the tour computer via a beacon connection device and beacon electronics,
  • f) the route computer transmits the respective route data and associated guide vector chains from the tour computer to the delivery vehicles leaving the loading station,
  • g) the situation-dependent route guidance to the customer is displayed in the delivery vehicles by means of the known guidance and information system on the display device of the guidance and information device.

Erfindungsgemäß wird ein Tourenoptimierungssystem eines oder mehrerer Fuhrunternehmer über Datenleitungen mit dem um einen Transportroutenrechner erweiterten Verkehrsleitrechner eines Verkehrsleit- und Informationssystems verbunden. Über die Datenleitungen werden in gewissen Zeitabständen Straßennetz­daten und Verkehrsdaten, wie sie beispielsweise durch Tages­ganglinien von Reisezeiten für jeweilige Streckenabschnitte im Straßennetz erfaßt sind, abgerufen. Im Tourenrechner des Fahr­unternehmers werden diese Daten mit den Tourenplanoptimierungs­daten verarbeitet und hieraus Tourenfolgen ermittelt, die zu­zusammen mit Leitvektorketten über Ladehofbaken, die an der Ausfahrt des Ladehofes installiert und mit dem Tourenrechner verbunden sind, an die ausfahrenden Lieferfahrzeuge übertragen. Es ist aber auch möglich, die voraussichtlichen Reisezeiten zwischen den Ladehöfen und den zu beliefernden Kunden bzw. die Fahrtzeiten von einem Kunden zu dem nächsten durch den zentralen Transportroutenrechner berechnen zu lassen und diese Reisezeiten an die Tourenrechner für den Fuhrunternehmer zu übertragen. Letztere können dann aufgrund der voraussichtlichen Reise- und Ladezeiten die optimalen Tourenfolgen bestimmen.According to the invention, a route optimization system of one or more hauliers is connected via data lines to the traffic control computer of a traffic control and information system which is expanded by a transport route computer. Road network data and traffic data, such as are recorded, for example, by daily trip lines of travel times for respective sections of the road network, are called up at certain time intervals via the data lines. In the tour operator's tour computer, this data is processed with the tour plan optimization data and tour sequences are determined from this, which, together with guide vector chains, are transmitted to the departing delivery vehicles via loading station beacons installed at the exit of the loading station and connected to the tour computer. However, it is also possible to have the estimated travel times between the loading stations and the customers to be supplied or the travel times from one customer to the next calculated by the central transport route computer and to transfer these travel times to the tour computer for the haulier. The latter can then determine the optimal tour sequences based on the expected travel and loading times.

Die Transportfahrzeuge empfangen die Adressen und Koordinaten der zu beliefernden Kunden in einer Reihenfolge, wie sie die Tourenfolgeoptimierung ergeben hat, gemeinsam mit Leitvektor­ketten durch ihre Leit- und Informationseinrichtung und verarbeiten diese bei der weiteren Fahrt mit den im Fahrzeug ermittelnden Ortungs- und Navigationswerten sowie mit den über weitere am Straßenrand installierten Leitbaken und von dort empfangenen Verkehrsleitdaten. Auf diese Weise ist es möglich, mit Hilfe der Zielführung die Kunden in kürzester Zeit zu beliefern.The transport vehicles receive the addresses and coordinates of the customers to be supplied in a sequence, as they have resulted from the tour sequence optimization, together with guidance vector chains through their guidance and information device and process them during the further journey with the location and navigation values determined in the vehicle as well as with the via other beacons installed on the roadside and traffic guidance data received from there. In this way, it is possible to deliver to customers in the shortest possible time with the help of route guidance.

Da der Güter- bzw. Lieferverkehr einen wesentlichen Anteil im Individualverkehr darstellt, führt eine derartige verkehrs­abhängige Routenoptimierung und als Folge davon eine gewisse Nivellierung von Verkehrsspitzen auf hochbelasteten Straßen zur Senkung von Energieverbauch und Abgaßemisionen. Ein weiterer Vorteil besteht darin, daß durch eine optimale Zielführung der Lieferfahrzeuge die Straßen gleichmäßiger genutzt und der Verkehr flüssiger gehalten werden kann. Mit dem Transport- und Verkehrsleitsystem werden laufend erfaßte Verkehrssituationen und neu auftretende Verkehrsstörungen, wie sie beispielsweise durch einen Unfall hervorgerufen werden, aufgrund der Leitweglenkung in der laufenden Tour mit berück­sichtigt. Dabei wird in einer vorteilhaften Weiterbildung der Erfindung mit der im Lieferfahrzeug installierten Leit- und Informationseinrichtung, die einen Ortungs- und Navigations­rechner sowie eine Reisezeitmeßeinrichtung aufweist, die jeweilige Fahrzeit zu und die jeweilige Standzeit bei den einzelnen Kunden gemessen und gespeichert. Diese jeweiligen Fahr- und Standzeiten werden mit den entsprechenden Kunden­adressen bei der Rückkehr des Lieferfahrzeugs in den Ladehof über die Ladehofbake vom Ortungs- und Navigationsrechner zum Transportroutenrechner übertragen und zur Berechnung der neuen optimalen Fahrroute gespeichert. Dieser sogenannte Fahrtbericht erlaubt es, aufgrund seiner Daten für künftige Fahrten eine verbesserte Routenoptimierung durchzuführen.Since freight or delivery traffic represents a significant proportion of individual traffic, such a traffic-dependent route optimization and, as a result, a certain leveling of traffic peaks on busy roads leads to a reduction in energy consumption and emissions emissions. Another advantage is that the roads are used more evenly by optimally guiding the delivery vehicles and traffic can be kept smoother. With the transport and traffic management system, continuously recorded traffic situations and emerging traffic disruptions, such as those caused by an accident, are taken into account due to the routing in the current tour. In an advantageous further development of the invention, the control and information device installed in the delivery vehicle, which has a location and navigation computer and a travel time measuring device, measure and store the respective travel time and the respective downtime for the individual customers. These respective driving and standing times are transmitted with the corresponding customer addresses when the delivery vehicle returns to the loading yard via the loading yard beacon from the location and navigation computer to the transport route computer and stored for the calculation of the new optimal driving route. This so-called trip report makes it possible to carry out improved route optimization based on its data for future trips.

Es ist vorteilhaft, die Standzeitmessung der Reisezeitmeß­einrichtung zu starten, sobald das Lieferfahrzeug in unmittel­barer Nähe der durch die Zielkoordinaten des betreffenden Kunden vorgegebenen Position abgestellt wird, und die Stand­zeitmessung zu beenden und damit die nächste Fahrzeitmessung zu starten, sobald das Lieferfahrzeug gestartet und eine eigens dafür vorgesehene Starttaste am Bediengerät des Ortungs- und Navigationsrechners betätigt wird. Damit wird die weitere Zielführung zum nächsten Kunden am Bediengerät angezeigt.It is advantageous to start the service life measurement of the travel time measuring device as soon as the delivery vehicle is parked in the immediate vicinity of the position specified by the target coordinates of the customer in question, and to end the service life measurement and thus to start the next travel time measurement as soon as the delivery vehicle starts and one specifically for this intended start button on the control unit of the location and navigation computer is pressed. This shows the further route guidance to the next customer on the operator panel.

Für die Berechnung der günstigsten Routen-Reisezeiten ist es zweckmäßig, die im Verkehrsleitrechner zur Verfügung stehenden Tagesganglinien der Reisezeit für jeweilige Streckenabschnitte im Transportroutenrechner für den Transportverkehr und für die Lieferfahrzeuge aufzubereiten. Dazu weist der Transport­routenrechner in der Leit- und Informationszentrale einen Transportganglinienrechner auf, der die voraussichtlichen Reisezeiten für die Lieferfahrzeuge ermittelt und zum Touren­rechner überträgt.For the calculation of the cheapest route travel times, it is advisable to prepare the daily route lines of the travel time available in the traffic management computer for the respective route sections in the transport route computer for the transport traffic and for the delivery vehicles. For this purpose, the transport route computer in the control and information center has a transport route computer which determines the expected travel times for the delivery vehicles and transmits them to the tour computer.

Gemäß einer anderen Ausgestaltung der Erfindung berechnet der zentrale Transportroutenrechner mit Hilfe eines oder mehrerer Routenrechner auf Anfrage eines Tourenrechners von einem Fuhrunternehmer die voraussichtlichen Reisezeiten zwischen seinem Ladehof und den zu beliefernden Kunden bzw. zwischen den Kunden. In diesem Falle werden den Tourenrechnern die bereits ermittelten voraussichtlichen Reisezeiten übertragen. Letztere haben dann lediglich die optimalen Tourenfolgen zu berechnen, indem sie die Summe aller Reise- und Ladezeiten für eine Tour minimieren. Zweckmäßigerweise werden die Daten der Kundennamen- ­und Adressenkoordinaten jeweils mit einer Kennziffer versehen, die das betreffende Lieferfahrzeug bezeichnet, welches die Ladungen für diese Kunden geladen hat.According to another embodiment of the invention, the central transport route computer calculates the expected travel times between its loading station and the customers to be supplied or between the customers by means of one or more route computers at the request of a tour computer from a haulier. In this case, the estimated travel times already determined are transferred to the tour computers. The latter then only have to calculate the optimal tour sequences by minimizing the sum of all travel and loading times for a tour. The data of the customer name and address coordinates are expediently each provided with an identification number which designates the delivery vehicle in question which has loaded the loads for these customers.

Diese Art der indivi­duellen Zielführung wird an jeder Leitbake LB des Leit- ­und Informationssystems ALI-SCOUT fortgesetzt, die von den Fahrzeugen im Laufe der weiteren Fahrt passiert werden. Links ist in Fig.2 ein rückkehrendes Lieferfahrzeug LFZr gezeigt, welches beim Einfahren in den Ladehof A seinen "Fahrtbericht" über die Ladehofbake LHB an den Touren­rechner TR3 abgibt. Die Leit- und Informationseinrichtung LIE der Lieferfahrzeuge LFZ weisen eine Reisezeitmeßeinrichtung RZM auf, die mit Hilfe des Ortungs- und Navigationsrechner ONR die Reisezeit, beispielsweise zwischen dem Fuhrunternehmer FU3 und dem Kunden B ermittelt. Erfindungsgemäß wird bei dem inte­grierten Transport- und Verkehrsleitsystem mit der Reisezeit­meßeinrichtung die jeweilige Fahrzeit zu und die Standzeit bei den einzelnen Kunden gemessen. Dabei beginnt die Standzeit­messung bei einem Kunden, wenn der Fahrer des Lieferfahrzeugs in der Nähe der durch die Zielkoordinaten vorgegebenen Position hält. Die Standzeitmessung endet beim Anfahren nach dem Betätigen einer eigens dafür vorgesehenen Starttaste am Bediengerät BG der Leit- und Informationseinrichtung LIE des Lieferfahrzeugs LFZ. Die Positionsbestimmung erfolgt durch den Ortungs- und Navigationsrechner ONR. Gemeinsam mit den Kunden­namen werden die Fahrzeiten zu diesen sowie die Standzeiten bei diesen im Ortungs- und Navigationsrechner gespeichert und bei der Rückkehr der Fahrzeuge LFZr in den Ladehof A über die Lade­hofbake LHB an den Tourenrechner TR3 übertragen. Auf der Basis dieser Daten werden die nächsten Touren optimiert.The integrated transport and traffic control system according to the invention is shown schematically in FIG. The traffic control and information center VLZ or LIZ has a traffic control computer VLR, which is connected on the one hand with operating and viewing devices and on the other hand with traffic switching devices VSG in the city area. The beacons LB are connected to each traffic control device VSG in addition to the traffic light system LSA. The individual hauliers FU1 to FU3 are connected to the traffic control and information center VLZ or LIZ via data lines DL1. Every haulier has a trip computer TR1 to TR3, which is used to optimize the trip plan. The example of the haulage contractor FU3 shows a loading yard A, the exit of which has loading yard beacons LHB, which are connected to the trip computer TR3 via a data line DL2. Furthermore, two delivery vehicles LFZ are shown in Fig. 2, which with a guidance and information LIE device according to Fig.1 are equipped. The right delivery vehicle LFZa leaves the loading yard A and receives the route data from the loading yard beacon LHB. With the help of the loading yard beacon LHB, the trip computer TR3 transmits the names, addresses and coordinates of the customers to be supplied (B) in the order in which the vehicles LFZa leave the loading yard and which the trip computer TR3 has calculated as time-optimal. In addition to the lists of customer addresses, guide vector chains are also transferred to the departing vehicles, which all describe the travel routes issued by their location, as described in European Patent 025 193, as well as a list of all possible destination fields with information on which routes to choose are. (This system is described in German patent application P 36 30 038.1). This type of individual route guidance is continued on every beacon LB of the guidance and information system ALI-SCOUT, which the vehicles pass during the further journey. A returning delivery vehicle LFZr is shown on the left in FIG. 2, which delivers its "journey report" to the trip computer TR3 via the loading yard beacon LHB when entering the loading yard A. The guidance and information device LIE of the delivery vehicles LFZ has a travel time measuring device RZM which uses the location and navigation computer ONR to determine the travel time, for example between the haulage contractor FU3 and the customer B. According to the invention, in the integrated transport and traffic control system with the travel time measuring device, the respective travel time and the standing time are measured for the individual customers. The service life measurement begins at a customer when the driver of the delivery vehicle stops near the position specified by the target coordinates. The service life measurement ends when starting after pressing a dedicated start button on the control unit BG of the control and information system LIE of the delivery vehicle LFZ. The position is determined by the location and navigation computer ONR. Together with the customer names, the travel times to these as well as the downtimes are added this is stored in the location and navigation computer and transmitted to the tour computer TR3 when the vehicles LFZr return to loading area A via loading area beacon LHB. The next tours are optimized on the basis of this data.

In Fig. 3 sind Tagesganglinien TGL für die Reisezeit tR1, tR2, tR3 usw. für drei Streckenabschnitte S1 bis S3 in Abhängigkeit von der Tageszeit t dargestellt. Wie später noch erläutert wird, werden in der Verkehrsleit- und Informationszentrale hieraus die zu erwartenden Reisezeiten für Routen berechnet, indem die Reisezeiten der einzelnen Streckenabschnitte addiert werden.FIG. 3 shows daily curve lines TGL for the travel time tR1, tR2, tR3 etc. for three route sections S1 to S3 depending on the time of day t. As will be explained later, the expected travel times for routes are calculated in the traffic control and information center by adding the travel times of the individual route sections.

In der Fig.4 ist das situationsabhängige Leiten für das er­findungsgemäße Transport- und Verkehrsleitsystem als ein dreidimensionales Problem dargestellt. Der Straßennetz­beschreibung SNB, die in digitalisierter Form in der x-y-Ebene im Verkehrsleitrechner gespeichert wird, ist die Zeit als 3.Dimension überlagert: Die "Zeitebenen" t₁,t₂,t₃ ... ent­sprechen dabei den Zeitintervallen t₁,t₂,t₃, ... in Fig.3. Die kleinen "Uhren" in Fig.4 symbolisieren die Reisezeiten für jeden Streckenabschnitt S₁,S₂, S₃, ... innerhalb der Zeitintervalle t₁,t₂,t₃ .... Diese Reisezeiten werden den Reisezeitgangkurven (Fig.3) entnommen.4 shows the situation-dependent routing for the transport and traffic management system according to the invention as a three-dimensional problem. The road network description SNB, which is stored in digitized form in the xy plane in the traffic control computer, the time is superimposed as a 3rd dimension: The "time levels" t₁, t₂, t₃ ... correspond to the time intervals t₁, t₂, t₃,. .. in Fig.3. The small "clocks" in Fig.4 symbolize the travel times for each route section S₁, S₂, S₃, ... within the time intervals t₁, t₂, t₃ .... These travel times are taken from the travel time curve (Fig.3).

Im Rechner werden aus diesen Daten die jeweiligen Routen optimiert, dadurch, daß diejenige Route ermittelt wird, für die die Summe aller Reisezeiten pro Streckenabschnitt ein Minimum ist. Ein Streckenabschnitt S₁, S₂,S₃, ... erstreckt sich jeweils von einem Knoten K₁,K₂,K₃, ... in der Straßen­netzbeschreibung SNB zum nächsten.From the data, the respective routes are optimized in the computer by determining the route for which the sum of all travel times per section of the route is a minimum. A route section S₁, S₂, S₃, ... extends from a node K₁, K₂, K₃, ... in the road network description SNB to the next.

Da für unterschiedliche Fahrzeugklassen unterschiedliche Reisezeiten gelten - so können bestimmte Streckenabschnitte z.B. für LKW gesperrt sein, wodurch die Reisezeit länger an­gesetzt werden muß - ergeben sich unter Umständen für ver­schiedene Fahrzeugklassen unterschiedliche Bestrouten, wie in Fig. 4 angedeutet: Während PKWs über eine kürzere Strecke von ihrem Ausgangsort A zu ihrem Zielort B geleitet werden und für ihre Fahrt 4 Zeitintervalle t₁ bis t₄ benötigen, müssen LKWs einen weiteren Weg nehmen und erreichern im Beispiel von Fig.4 im 6. Zeitintervall ihr Ziel B (Kunde).Since different travel times apply to different vehicle classes - for example, certain sections of the route can be blocked for trucks, which means that the travel time has to be set longer - there may be different best routes for different vehicle classes, as indicated in Fig. 4: During cars over a shorter route from their starting point A to their destination B and need 4 time intervals t₁ to t₄ for their journey, trucks have to take a further route and reach their destination B (customer) in the example of Fig.4 in the 6th time interval.

In Fig. 5 ist das integrierte Transport- und Verkehrsleitsystem im Blockschaltbild dargestellt. Die Verkehrsleit- und In­formationszentrale ist hier in die Verkehrsleitzentrale der Polizei VLZP und in die Leit- und Informationszentrale LIZ ge­gliedert. Der Verkehrsleitrechner VLR, wie in Fig.1 und 2 gezeigt, besteht aus mehreren Rechnern, die durch ein Ring­bussystem miteinander verbunden sind. Ein Bedienrechner BR steht in der Verkehrsleitzentrale der Polizei VLZP. Der Leit- ­und Informationsrechner wird von einem Versorgungsrechner VR, der zur Eingabe und Aktualisierung des Straßennetzes dient, von einem Ganglinienrechner GLR, der die Reise- und Stauzeiten verarbeitet, und von mehreren Routenrechnern RR1 bis RR3, die zur Berechnung der optimalen Routen dienen, gebildet. An diese sind über Knoten die einzelnen Leitbaken angeschlossen.5 shows the integrated transport and traffic management system in the block diagram. The traffic control and information center is divided into the traffic control center of the police VLZP and the control and information center LIZ. The traffic control computer VLR, as shown in FIGS. 1 and 2, consists of several computers which are connected to one another by a ring bus system. A control computer BR is in the traffic control center of the police VLZP. The guidance and information computer is formed by a supply computer VR, which is used to enter and update the road network, by a gangway computer GLR, which processes the travel and traffic jam times, and by several route computers RR1 to RR3, which are used to calculate the optimal routes . The individual beacons are connected to these via nodes.

Das erfindungsgemäße Transport- und Verkehrsleitsystem dient der optimalen Routen- und Zielführung von Lieferfahrzeugen, also LKWs. Das heißt, daß deren Belange an die Zielführung besonders berücksichtigt werden müssen: LKWs sind oftmals über andere Routen zu führen, weil beispielsweise bestimmte Straßen für sie gesperrt sind. Auch dürfen Fahrzeuge mit gefährlichen Ladungen Tunnelstrecken nicht benutzen. Ferner gibt es Brücken oder Unterführungen, für die Gewichts-, Höhen-, Längen-oder Breitenbeschränkungen der Fahrzeuge bestehen. Deshalb ist das Straßennetz entsprechend für die Lieferfahrzeuge aufberei­tet. Ebenso sind die Reisezeiten der LKWs von den Reisezeiten für PKWs unterschiedlich. Daher sind in der Leit- und Infor­mationszentrale LIZ den oben erwähnten Rechnern weitere Rechner zugeordnet, die mit den übrigen Rechnern über eine Ringbusleitung verbunden sind. Ein Ganglinienrechner TGLR für die Berechnung der Reisezeit der Lieferfahrzeuge und drei Routenrechnern TRR1 bis TRR3 für die Berechnung der Liefer­fahrzeugrouten sind als ein Rechner zusammengefaßt, der mit Transportroutenrechner TRR bezeichnet ist. Dieser Transport­routenrechner TRR ist über eine Übertragungseinrichtung MODST, MOD mit den Tourenrechnern TR der Fuhrunternehmer FU ver­bindbar. Dies ist in der Fig.5 rechts dargestellt. Die Über­tragungseinrichtung besteht hierbei aus einer Modemsteuerung MODST und einem Wählmodem MOD, welches über das öffentliche Fernsprechnetz ÖN bzw. die Datenleitung DL1 den Transport­routenrechner TRR mit dem Tourenrechner TR verbindet.The transport and traffic control system according to the invention is used for optimal route and destination guidance of delivery vehicles, ie trucks. This means that their needs for route guidance have to be given special consideration: trucks are often to be led via other routes because, for example, certain roads are blocked for them. Vehicles with dangerous loads are also not allowed to use tunnel routes. There are also bridges or underpasses for which there are weight, height, length or width restrictions for the vehicles. The road network is therefore prepared for the delivery vehicles. Likewise, the travel times of the trucks are different from the travel times for cars. Therefore, in the control and information center LIZ there are more computers mentioned above Assigned computers that are connected to the other computers via a ring bus line. A chart computer TGLR for calculating the travel time of the delivery vehicles and three route computers TRR1 to TRR3 for calculating the delivery vehicle routes are combined as one computer, which is referred to as the transport route calculator TRR. This transport route computer TRR can be connected to the tour computers TR of the hauliers FU via a transmission device MODST, MOD. This is shown on the right in Fig. 5. The transmission device here consists of a modem control MODST and a dialing modem MOD, which connects the transport route computer TRR to the tour computer TR via the public telephone network ÖN or the data line DL1.

In Fig. 6 ist dargestellt, wie der Tourenrechner TR beim Fuhr­unternehmer FU mit weiteren Einrichtungen für das Transport- ­und Verkehrsleitsystem ergänzt ist. An den Tourenrechner TR ist ein Modem für das Fernsprechwählnetz MODFU angeschlossen. Ferner sind an dem Tourenrechner TR über eine Bakenanschlußein­richtung BAE und eine Bakenelektronik BEFU Ladehofbaken LHB angeschlossen, wie das anhand der Fig.2 schon erläutert wurde.FIG. 6 shows how the trip computer TR at the haulage contractor FU is supplemented with further facilities for the transport and traffic control system. A modem for the telephone dialing network MODFU is connected to the trip computer TR. Furthermore, loading yard beacons LHB are connected to the tour computer TR via a beacon connection device BAE and beacon electronics BEFU, as has already been explained with reference to FIG.
