specific Embodiment approach 1

[0050] Specific implementation mode one: combine figure 1 The present embodiment is described. The present embodiment provides a vehicle speed guidance system for reducing parking at signalized intersections, including:

[0051] The traffic signal control subsystem is used for real-time control of the phase of the signal light according to the real-time traffic conditions, receiving the traffic signal phase request information from the vehicle speed guidance device 6, and feeding back the corresponding traffic signal phase information to the vehicle speed guidance device 6;

[0052] The vehicle speed guidance device 6 is installed on the vehicle, communicates with the traffic signal control subsystem in real time, sends a traffic signal phase information request to the traffic control subsystem at a certain frequency through communication, and receives feedback information from the traffic signal control subsystem, Provide a reasonable suggested speed value to the vehicle acco...

specific Embodiment approach 2

[0053] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the traffic signal control subsystem includes: a vehicle information receiver 3, a signal system management server 1, a signal system area server 2, a signal front-end device 5 and Signal information transmitter 4;

[0054] The vehicle information receiver 3 is connected with the signaling system management server 1, receives a request from the vehicle speed guidance device 6 to retrieve (next signalized intersection) traffic signal phase information, and sends the retrieval request to the signaling system management server 1;

[0055] The signaling system management server 1 receives the traffic signal phase information request (next signalized intersection) from the vehicle information receiver 3, and retrieves the corresponding traffic signal phase information from the signaling system area server 2 according to the traffic signal phase information that the vehicle expects to obtain. signal...

specific Embodiment approach 3

[0060] Specific Embodiment 3: The difference between this embodiment and Specific Embodiment 2 is that the signal front-end device 5 includes a signal lower computer and a signal light, and the signal lower computer is connected to the signal light, and the signal The lower computer is used for real-time phase control of the corresponding signal lights.

[0061] Other steps and parameters are the same as in the second embodiment.

Abstract

The invention provides a speed guiding system and method that reduces signal intersection pausing, and belongs to the traffic management and control technical field; the speed guiding system comprisesthe following parts: a traffic signal control subsystem used for controlling a signal lamp phase in real time according to real time traffic conditions, receiving traffic signal phase request information from a speed guiding device, and returning the corresponding traffic signal phase information to the speed guiding device; the speed guiding device arranged on a vehicle and used for communicating the traffic signal control subsystem in real time, sending the traffic signal phase information request to the traffic control subsystem with certain frequency via communication, receiving feedbackinformation from the traffic signal control subsystem, and providing a suggestion speed value for the vehicle according to the feedback information. The speed guiding system and method can solve the problems that an existing method cannot control to reduce the signal intersection pausing problem; the speed guiding system and method can be applied to intersection speed guiding.

Description

technical field [0001] The invention relates to a vehicle speed guidance system and method for reducing parking at signalized intersections, belonging to the technical field of traffic management and control. Background technique [0002] The level of service at a signalized intersection is determined based on the obstruction of vehicles at the signalized intersection. Control delays include stop delays due to signal lights and deceleration and acceleration delays experienced by queuing vehicles when they stop and start. Parking caused by control signals at signalized intersections will not only lead to additional energy consumption and emission pollution, but also reduce the driving experience and affect the driver's driving psychology. [0003] In order to improve the driving speed of urban arterial roads and the utilization rate of green lights at intersections, green wave control came into being. The so-called "green wave control" refers to connecting the traffic signa...
