A lane traffic efficiency optimization grouping device and method

Abstract

The invention discloses a lane traffic efficiency optimization grouping device, comprising: a data acquisition module for acquiring lane information of each lane of a current road section in a predetermined time period; a lane grouping scheme generation module for generating a lane grouping according to the lane information In the scheme, the lanes in each lane grouping scheme are continuous. According to the binary tree derivation rules, all the grouping schemes that have traversed the lanes are generated in turn; Check all the lane grouping schemes that have passed the test, and extract the lane grouping schemes that have passed the test; the lane grouping scheme evaluation index calculation module is used to calculate the evaluation indicators of the lane grouping schemes that have passed the test; the lane grouping scheme traffic efficiency evaluation module is used to group each lane. The traffic efficiency of the scheme is evaluated, and the lane grouping scheme with the best traffic efficiency is obtained. The adoption of the technical solution improves the traffic efficiency of vehicles.

Description

technical field [0001] The invention relates to the traffic field, in particular to a lane traffic efficiency optimization grouping device and method. Background technique [0002] With the rapid increase of car ownership, road congestion has become a public problem that seriously affects people's daily life and social development. Road congestion, on the one hand, is that road resources cannot meet the needs of vehicles, and on the other hand, it is caused by seizing lanes at road bottlenecks. Road resources are restricted by many factors such as land resources and planning, and cannot be changed in a short period of time. The most fundamental manifestation of the so-called road bottleneck is that the number of traversable lanes changes from more to less. This kind of bottleneck generally has two situations, (1) the number of road lanes changes from more to less; (2) the number of traversable lanes becomes less due to construction, traffic accidents or temporary traffic c...

AI Technical Summary

Problems solved by technology

[0003] In places with road bottlenecks, there is no good solution to the road congestion caused by seizing lanes. Generally, no intervention is carried out, and the traffic flow will naturally decrease and disappear; this will inevitably lead to road congestion time. long, frequent collision accidents, low traffic efficiency, etc.

However, artificial traffic control by traffic police faces problems such as lack of real-time performance, low efficiency, and the need to invest a lot of human resources. At the same time, it also poses a certain threat to the personal safety of traffic police.
