Dynamic setting method, device and vehicle-mounted device of intermittent priority bus lane

Abstract

The invention discloses a dynamic setting method for intermittent preferential bus transit lanes. The method includes the following steps that 1, a bus acquires position information and speed information of all social vehicles within the range of at least two bus stalls in front of the bus and at least two bus stalls behind the bus on a road where the bus is located in real time, and the current road service level is calculated according to the average speed of all the social vehicles within the range; 2, the bus sends an avoiding instruction to part of the social vehicles on the road where the bus is located according to the current road service level; 3, the step 1 and the step 2 are repeatedly executed. The invention further discloses a dynamic setting device for the intermittent preferential bus transit lanes and a vehicle-mounted device. Under the condition that actual road conditions are fully considered, a small number of social vehicles in front of the bus are notified of avoiding, the utilization rate of road resources can be greatly increased while the operating speed of the bus is guaranteed, the influences on the social vehicles are reduced, implementation is easy, and the implementation cost is low.

Description

technical field [0001] The invention belongs to the field of urban traffic management and control, and in particular relates to a dynamic setting method and device for intermittent priority bus lanes. Background technique [0002] With the increasingly severe urban traffic problems, giving priority to the development of public transport has become the consensus of all countries in the world. Bus-only lanes are an important measure of bus priority, and have achieved good results in alleviating urban traffic congestion, saving energy, and reducing urban air pollution. However, ordinary bus lanes are suitable for urban roads with large bus traffic. For urban roads with small bus flow and large social traffic flow, the opening of bus lanes will reduce the number of social lanes, reduce the utilization rate of traffic capacity, and may increase the average delay of social vehicles and the fragility of the traffic system non-development of bus-only lanes will lead to poor operat...

AI Technical Summary

Problems solved by technology

This method is more convenient than roadside detection, but it still needs indicator lights and vehicle-road coordinated control to restrict vehicles from entering the dedicated lane and prompt vehicles on the dedicated lane to leave. This method is technically difficult and expensive

[0007] To sum up, it can be seen that the existing intermittent priority bus lane setting method not only has the problems of high technical difficulty and high implementation cost, but more importantly, the utilization rate of road resources is still low, and the influence of actual road conditions is not considered.
