Embodiment Construction

[0039] For traffic accidents, the premise of rapid handling is to arrive at the accident scene quickly. The present invention obtains the method for rushing to the optimal path of the traffic accident scene, taking the police cars near the accident scene as objects, respectively calculating the shortest time and the fastest path for these police cars to reach the accident scene, comparing the shortest time of these police cars, and taking the shortest shortest time The corresponding fastest path is taken as the optimal path, and the police car corresponding to the optimal path can use the optimal path to rush to the accident scene to achieve the goal of arriving at the accident scene in the shortest time. The method will be explained in detail below in conjunction with the accompanying drawings.

[0040] The present invention obtains the method for rushing to the optimal path of the traffic accident scene, such as figure 1 shown, including the following steps:

Abstract

The invention discloses a method and device for obtaining an optimal path to hurry to a scene of a traffic accident. The method comprises the following steps of: respectively calculating fastest paths for police cars around an accident scene to arrive at the accident scene and selecting one path which consumes the shortest time from all the fastest paths as the optimal path; and announcing the police car corresponding to the optimal path to hurry to the accident scene by adopting the optimal path, thus arriving at the accident scene in the shortest time. Therefore, by utilizing the method, the accident spread is avoided, the injuries and deaths can be reduced; and the time for processing the traffic accident is effectively saved by the method. In the method, when the fastest driving paths of the police cars are calculated, each driving path is segmented at first and then the driving time of the whole driving path is calculated through calculating an average car speed of each segment of the path, so that the fastest driving path is found out. As the path is segmented, the calculated average speed is more precise and more accurate. The invention also discloses a device corresponding to the method; and the method and the device are combined so that the police car can arrive at the accident scene in the shortest time.

Description

technical field [0001] The invention relates to the technical field of traffic control, in particular to a method and a device for obtaining an optimal route to a traffic accident scene. Background technique [0002] With the development of cities, the traffic is becoming more and more congested, traffic jams have become commonplace, and traffic accidents also occur frequently. For the traffic control system, after a traffic accident occurs, it is the most important thing to rush to the scene of the accident as soon as possible. [0003] Vehicles driving in the city are generally equipped with on-board GPS, which brings convenience to the positioning and speed measurement of the vehicle, but only knowing the position and speed of the vehicle is not enough to solve the problem of quickly arriving at the scene of a traffic accident. Contents of the invention [0004] The present invention proposes a method and device for obtaining an optimal route to the scene of a traffic ...
