Setting method of improving traffic efficiency of road network of high density development district

Abstract

The invention discloses a setting method of improving the traffic efficiency of a road network of a high density development district. A uniform square road network is used in a regional road network; the number of lanes of the road in the regional road network is determined by traffic flow forecasting data; all roads in the regional road network are one-way streets, and any two adjacent parallel roads in the regional road network are one-way streets which are opposite in direction; two phase traffic control signals are arranged at intersections of the one-way streets in the regional road network to separately control straight going vehicles in two vertical directions, and control signals are not independently arranged for left turning vehicles; and the traffic control signals are in a green wave band coordinated control mode. The parking queue and delay phenomena at the intersections are greatly reduced, so that traffic jam of the intersections is effectively avoided, and the traffic efficiency of the road network in the district is increased; and meanwhile, the average traveling time of the vehicle is shortened, the traffic efficiency of joining the road network of the region and an external road network is greatly improved, the traveling energy consumption of the vehicle is also reduced, the traveling cost is lowered, and the setting method is green and environmental-friendly.

Description

technical field [0001] The invention relates to the technical field of road traffic, in particular to a setting method for improving the traffic efficiency of a road network in a high-density development area. Background technique [0002] There are many high-density development areas in large cities, for example, a certain area is about 4km 2 In the high-density development of business office areas, the regional road network structure generally adopts a grid-shaped urban road network, and the road intersections are simple or flat interchanges. There are dozens to dozens of planes that need to be controlled by signal lights in the entire area. intersection. [0003] The road traffic in the area is dominated by external traffic and internal traffic, and transit traffic is negligible. Due to the influence of the structure of the grid road network, the proportion of road traffic turning in the area is relatively high. Referring to relevant information, the formula for calcula...

AI Technical Summary

Problems solved by technology

[0007] The ratio of left turns is a key factor affecting the traffic capacity of urban intersections. When the ratio of left turns is high, the grid-shaped urban road network is restricted by the traffic capacity of a large number of level intersections. The overall traffic operation efficiency is low and it is difficult to meet high-density development. The resulting traffic demand manifests itself in traffic congestion, frequent parking, long queuing distances, and low service levels
