Abstract
The invention provides a system for automatically recording behaviors that motor vehicles do not slow down and yield when passing through a crossroad with the Yield sign. When motor vehicles pass through a crossroad with the Yield sign, the system continuously track the motor vehicles in real time both in Slow Down-Yield direction and priority pass direction through video tracking and detecting equipment. The system can be used for automatically monitoring in real time that whether the motor vehicles in the Slow Down-Yield direction slow down or not and whether the behavior that the motor vehicles pass through the Slow Down-Yield line leads to slowing down or stop of the motor vehicles in the priority pass direction or the safe intervals between the motor vehicles passing through the Slow Down-Yield line and the motor vehicles in the priority pass direction are smaller than a set safe distance threshold value. If the conditions are satisfied, the system immediately photographs and records the unlawful behaviors of the motor vehicles in the Slow Down-Yield direction for breaking the Yield rule.
Description
Technical field
The present invention relates to traffic administration field, specifically do not give way the system of behavior in pass through crossing of giving way of a kind of automatic recorder motor-car.
Background technology
Pass through in order to ensure crossing orderly, safe, unimpeded, vehicle supervision department crossing motor vehicle flow do not reach adopt signal lamp to carry out the required standard controlled time, the general yield signs graticule that adopts carries out control of giving way, to improve crossing traffic efficiency.
But, current domestic driver operating motor vehicles pass through give way direction by crossing time, motor vehicle is seldom had initiatively to slow down close to during crossing according to regulation, whether observe priority pass direction when arriving crossing has motor vehicle to be introduced into crossing, and note avoiding the reducing speed of motor vehicle or the parking that cause priority pass direction, finally cause accident to occur.
To give way mark according to 5.3 regulations in standard GB/T 5768.2-2009: represent that vehicle should give way, bulletin vehicle drive people should be slowed down or stop, and observes main line driving situation, is guaranteeing that arterial highway vehicle is preferential, guaranteeing under safe prerequisite, crossing of being allowed for access.
Specify to give way line according to 5.6.2 in standard GB/T 5768.3-2009: the line that gives way represents that vehicle should slow down at this crossing makes arterial highway vehicle leading.
According to accident statistics form, several more than 20% is played because caused traffic hazard of giving way not according to regulation accounts for total accident, in order to solve motor line Stop and give way through needs Stop and give way crossing problem in accordance with the law, in prior art, propose system for automatically monitoring running vehicle and the operation method thereof to violating the regulation that gives way
Patent documentation CN100476899 discloses a kind of motor vehicle to form vehicle automatic checkout system and the operation method thereof of violating the regulation that gives way, this system by have right-of-way vehicles or pedestrians detecting device, before and after two wagon detectors, in violation of rules and regulations automobile image recording unit and their joining process computers form to allow line.System operation method be detect that vehicle successively takies branch line allow line rear vehicle detecting device and allow interval time between line vehicle in front detecting device, if be less than the minimum line time T that allows of regulation, judge that this vehicle violates the regulation that gives way, even if be not less than the minimum line time T that allows above-mentioned interval time, if detect now to have the vehicles or pedestrians detecting device of right-of-way occupied, still judge that this vehicle violates the regulation that gives way, determined violation gives way after regulation, namely start in violation of rules and regulations automobile image recording unit to this vehicle shooting record.
But, in the program, when only having motor vehicle to stop on the detector, just can detect that this car stops, if although after this motor vehicle is parked in that Stop and give way line, do not stop on the detector, then easily judge by accident.In addition, in the program, accurately cannot judge to allow the motor vehicle of line direction whether cause the reducing speed of motor vehicle in priority pass direction or the situation of parking, therefore effectively can not supervise the motor vehicle behavior of not giving way at Stop and give way crossing in accordance with the law.
Summary of the invention
For this reason, technical matters to be solved by this invention is the illegal activities of in accordance with the law not giving way for the motor vehicle at crossing of giving way in prior art, can not supervise comprehensively and effectively, thus provide a kind of automatic recorder motor-car to pass through to give way the system that behavior is not given way at crossing.
For solving the problems of the technologies described above, the system providing a kind of automatic recorder motor-car to pass through to give way crossing not give way behavior of the present invention.
The invention provides pass through crossing of giving way of a kind of logging machine motor-car not give way the system of behavior, be arranged on and require that reducing speed of motor vehicle gives way crossing, described crossing of giving way is executed in the direction that needs give way to draw and is given way line and arrange the sign board that gives way, execute in priority pass direction and draw stop line, comprising:
