Method of Setting Free Direction-changing Areas at Intersections Based on Symmetrical Phase and Unbalanced Traffic Flow

A symmetrical phase, non-equilibrium technology, applied in the control of traffic signals, traffic control systems, traffic control systems for road vehicles, etc., can solve problems such as large traffic flow in a single lane, congestion, waste of green light time at the entrance, and reduce delays. time, the effect of alleviating traffic congestion

Abstract

A method for setting a free direction-changing area at a symmetrical phase unbalanced traffic flow intersection disclosed by the present invention includes the following steps: Step 1, in front of the parking line of the entrance road of the fixed-direction area, that is, the parking line of the entrance road of the fixed-direction area faces the intersection Set up a free direction-changing area on one side of the entrance; step 2, establish a control plan for the signal light group at the entrance road in the fixed direction area and the signal light group in the free direction change area; the signal light group at the entrance road in the fixed direction area is used to indicate the rear of the stop line at the entrance road in the fixed direction area The vehicle control scheme in the free direction changing area; the signal light group in the free direction changing area is used to indicate the vehicle control scheme in the free direction changing area. The present invention increases the number of vehicles passing through the intersection in each phase by increasing the number of entrances to the free direction-changing area at the intersection. Provide more optional routes for vehicles at intersections to meet the direction-changing requirements of intersection traffic. When the signal timing cycle at intersections is long, it can significantly reduce intersection delay time, enabling vehicles to enter intersections in an orderly manner. Effectively relieve traffic jams in high-traffic lanes.

Description

technical field

[0001] The invention belongs to the technical field of urban traffic management, and relates to a method for setting free direction-changing areas at intersections based on symmetrical phases and unbalanced traffic flows. Background technique

[0002] With the rapid development of my country's social economy, the process of urbanization is accelerating, and the scale of cities continues to expand, resulting in a sharp increase in urban traffic demand. The construction of urban roads is relatively lagging behind the growth of motor vehicles, and the poor road network structure of road construction focuses on trunk roads and neglects secondary roads, which leads to the occurrence of common urban problems-traffic congestion, especially at road level intersections. Traffic congestion has led to a decline in traffic efficiency and also caused serious environmental pollution.

[0003] At the front end of the entrance road at the intersection of existing urban road...
