Problems solved by technology
[0005] 1. The acquisition of the priority vehicle status mainly relies on the communication between the vehicle fixed terminal and the intersection sensor equipment, which not only increases the cost of infrastructure construction and maintenance, but also leads to the simplification of user types, and it is impossible to flexibly provide signal priority services for different users ;
[0006] 2. From the perspective of user service, for urban traffic managers, it does not provide background monitoring and management functions, and lacks decision-making and management support; for on-site users, the system has certain defects in operability, reliability, and practicability , the system functions lack intelligent and humanized design

Embodiment Construction
[0021] Below in conjunction with specific embodiment, further illustrate the present invention, should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention, after having read the present invention, those skilled in the art will understand various equivalent forms of the present invention All modifications fall within the scope defined by the appended claims of the present application.
[0022] like figure 1 The overall network topology of the system is shown in Figure 5, which mainly describes the communication connection between the traffic command center LAN and the external terminal. Among them, the command center establishes a communication connection with the GPS data acquisition terminal (that is, the terminal device integrated with the GPS positioning module) and the mobile terminal of the on-site user through a dedicated wireless network; establishes a communication conne...

The invention relates to a special vehicle signal priority control system based on a signal control system on the bases of a terminal device and a port opened to the outside of an integration global positioning system (GPS) locating module. Depending on an intelligent mobile terminal and browser / server (B / S) framework, the special vehicle signal priority control system respectively provides various application and management services of special vehicle signal priority control for a user in site and a user in a command center. According to the special vehicle signal priority control system, a pattern of two-level application and management service for the user in site and the user in the command center is adopted, so that autonomous and intelligent signal priority service can be offered to various special vehicles flexibly and decision and management support for a special vehicle signal priority mission is offered to a traffic manager. The special vehicle signal priority control system is strong in economy, operability, reliability and practicality and capable of improving city traffic management level and efficiency and deepening city intelligent transportation system construction.
Description
technical field [0001] The invention relates to the field of intelligent traffic signal control, in particular to a special vehicle priority control system based on GPS positioning data. Background technique [0002] Special vehicles, such as fire trucks, ambulances, emergency vehicles, police cars, etc., perform special missions that are directly related to the safety of people's lives and property. Therefore, it has always been one of the important responsibilities of urban traffic managers to protect their right to drive on roads. . [0003] The execution of traditional signal priority tasks requires dispatching a large number of police forces to signalized intersections where priority vehicles pass in advance. Through the collaboration between traffic police on duty, artificially adjust the working status of signal machines to open up signal priority paths for special vehicles. With the popularization of the distributed urban traffic signal control system, the remote co...
