Problems solved by technology

At present, most of the traffic guidance methods start from the analysis of road sections and intersections, and the relationship between intersections and intersections to judge the road network traffic conditions. The amount of calculation and processing information is relatively large, which cannot meet the real-time requirements of traffic guidance.

Embodiment 2

[0098] The difference between the present embodiment and the traffic guidance method of embodiment one is:

[0099] When there is no bottleneck congestion point in the main traffic artery, or when there is a bottleneck congestion point, but the ratio of the travel time of the detour route of the main traffic artery to the travel time of the main traffic artery does not exceed the ratio threshold, the present invention The traffic guidance method of embodiment also includes:

[0100] generating second or third inducing information, and publishing the generated inducing information; wherein, the second inducing information includes the location of the bottleneck congestion point; and the third inducing information includes a reminder that there is a congestion point. in,

[0101]The first induction information also includes: the position of the bottleneck congestion point, the congestion information of the intersection, etc.; the second induction information also includes the d...

Embodiment 3

[0104] The difference between this embodiment and the traffic guidance method of Embodiment 1 or Embodiment 2 is: in addition to including the implementation process of the traffic guidance method of Embodiment 1 or Embodiment 2, the traffic guidance method of the embodiment of the present invention also includes:

[0105] Correspondingly mark the congestion information of the determined intersections on the position corresponding to each intersection on the map, and send the map to the traffic management center or publish it on the guidance screen.

[0106] Specifically, the corresponding marking of the congestion information on the map includes:

[0107] a1. Divide the value range of the delay time into [0,10s], (10s,35s], (35s,60s], (60s,∞) in advance, and the four intervals correspond to the first to fourth levels of congestion levels; Among them, the first level is unimpeded, the second level is slight congestion, the third level is moderate congestion, and the fourth lev...

Abstract

The invention relates to a traffic guidance method. The traffic guidance method includes the steps that when periodic or segmental congestion information is updated, the following steps will be carried out on each main transit corridor, firstly, for each intersection, congestion information of the intersection within set duration from the current moment is backtracked, secondly, whether the intersection is a bottle neck congestion point or not can be judged according to the backtracked congestion information of the intersection, and thirdly, the judging result is recorded; judging results of the intersections are traversed, and vital communication lines which the bottle neck congestion points exist on the main transit corridors can be found out; it is determined that the ratio of the travel time of bypassing lines of the found vital communication lines to the travel time of the vital communication lines exceeds a proportional threshold value, and first guidance information is generated and issued. According to the traffic guidance method, road network traffic conditions can be judged rapidly and accurately, and real-time traffic guidance can be achieved.

Description

technical field [0001] The invention relates to the field of intelligent traffic, in particular to a traffic guidance method. Background technique [0002] Traffic guidance is based on modern technologies such as electronics, computers, networks and communications, and helps road users find the optimal route from the starting point to the destination through real-time traffic information. Its characteristic is to consider people, vehicles and roads together, improve the road traffic system by inducing the travel behavior of road users, prevent traffic jams, reduce the time of vehicles staying on the road, and finally realize the traffic flow in the road network. Reasonable distribution on each road segment. [0003] The key to realizing traffic guidance is to be able to synthesize the traffic information of each road section and each intersection that compose the road network, quickly and accurately judge the traffic conditions of the road network, and then generate guidanc...
