Direction switching method for variable lane of urban road

Abstract

The invention discloses a direction switching method for a variable lane of an urban road, which is oriented to crossing signal timing dial and a variable lane indicating lamp position and is mainly used for switching from bidirectional balanced traffic to bidirectional unbalanced traffic. The invention aims to complete direction switching of a variable lane of an urban road in two signal periods, ensure smooth lane change of vehicles on the variable lane, reduce wrong lane change to the maximum extent and establish a direction switching method for a variable lane of an urban road, which is oriented to crossing signal timing dial and a variable lane indicating lamp position. The method comprises the following specific steps of: arranging indicating lamps on the variable lane of the urban road; arranging a guide lane on a crossing through which the variable lane passes; performing a direction switching process on the variable lane of the urban road; and determining whether an indicating lamp arranging position on the variable lane in a certain section meets a certain requirement.

Description

technical field [0001] The invention belongs to the field of road traffic control, and in particular relates to a method for changing the direction of a variable lane on an urban road facing intersection signal timing and the position of a variable lane indicator light. Background technique [0002] With the acceleration of the process of urbanization and motorization in our country, urban traffic is becoming more and more congested. At the same time, the space mismatch between employment and residence, the separation of employment and residence, and the tidal phenomenon are becoming more and more obvious, which have become one of the important causes of traffic congestion. The main measure to alleviate the tidal traffic problem is the traffic organization of variable lanes. However, my country's variable lanes lack uniform design standards, implementation guidelines and management basis, and the guiding role of variable lane-related signs and markings and variable lane lig...

However, my country's variable lanes lack uniform design standards, implementation guidelines and management basis, and the guiding role of variable lane-related signs and markings and variable lane lights has not been highlighted

At present, the direction change of variable lanes in our country is manually switched by the traffic police on duty according to the traffic flow conditions on the spot. On the one hand, the time of direction change is often ahead of time or lags behind the best switching time, which cannot make full use of variable lanes; on the other hand, there is no effective The use of variable lane indicators does not guarantee smooth lane changes and minimal wrong lane changes
