Abstract
The invention provides a vehicular access cooperative system with an early warning prompting function for red light running and a method. The vehicular access cooperative system comprises an intersection controller, a vehicle-mounted controller and a voice prompter. The intersection controller is used for collecting signal light information and stop line position information of the vehicle driving direction, and transmitting the collected information to the vehicle-mounted controller. The vehicle-mounted controller is used for obtaining position information of vehicles, speed information of the vehicles, receiving the collected information transmitted by the intersection controller, and processing the obtained information and the collected information. The voice prompter is used for carrying out voice prompt to drivers. Due to the fact that the intersection controller transmits the signal light information of the vehicle driving direction and global position system (GPS) information of the vehicle driving direction to the vehicle-mounted controller, and an early warning and decision-making module is utilized to give out aid decision-making information that whether a driver can pass through an intersection and whether the driver needs to slow down and brake, and transfer the information to the driver in a voice prompt mode, the vehicular access cooperative system avoids the occurrence of the action that the driver mistakenly runs the red light when a traffic light is yellow, and reduces traffic accident rate.
Description
Technical field
The present invention relates to technical field of traffic control, particularly a kind of collaborative early warning system of bus or train route and method with the early warning function of making a dash across the red light.
Background technology
The phenomenon of making a dash across the red light at the intersection place at present often occurs, there is certain limitation in traditional signal control method in the minimizing behavior of making a dash across the red light, especially at amber light constantly, the driver is that " walking " or " stopping " are not fixed unified standard on earth, and the driver can only select " walking " or " stopping " according to own experience, generally, when the driver ran into amber light, if distant apart from the crossing, most of can the selection stopped, if closer apart from the crossing, then can select to pass through.Potential range crossing when yet the driver runs into amber light " not far not near ", add the driver because driving experience, judgement difference to some extent, such situation may appear, in the time of can not having satisfied the driver by the crossing in yellow time, some drivers are owing to error in judgement is selected to pass through, the generation of the phenomenon that causes making a dash across the red light.Thereby when the driver enters the crossing and runs into amber light, should there be relevant early warning information can help the driver to carry out the judgement of " walking " or " stopping ".
For the amber light behavior of making a dash across the red light constantly, the present driver early warning technology that makes a dash across the red light also can be divided into two kinds, and a kind of is traditional early warning technology, and another kind is based on the collaborative early warning technology of bus or train route.Traditional early warning technology is to come alerting driver to need to stop by more additional flag informations, signal lamp variation etc., and this early warning technology cost is low, easy for installation, and there is dispute in result of use.By the key parameters such as the speed of steering vehicle, position, yellow time are analyzed based on the collaborative early warning technology of bus or train route, judge that can this vehicle pass through the crossing within yellow time, if can not safety, then provide the prompting such as the early warning information of noting deceleration by prior-warning device in the car to the driver, thereby avoid the driver to be not intended to make a dash across the red light, this technical application is strong, accuracy rate is high but technical costs is higher, needs to communicate by letter, that computing machine etc. is multi-field is auxiliary, is at present conceptual phase.
