Signal-controlled intersection special lane and traffic capacity computing method thereof

Abstract

The invention provides a signal-controlled intersection special lane. Due to the fact that the special lane is provided with a special-width lane body and a first narrow lane body and a second narrow lane body are further arranged in the special-width lane body, the special lane can serve as a large vehicle driving lane and can also serve as driving lanes for two small vehicles, and the width range is 5.0-5.2 m. therefore, under the condition that the lane width is not increased significantly, existing road resources can be fully utilized, and the traffic capacity of city signal-controlled intersection is improved. In addition, through a provided computing method for the traffic capacity of the signal-controlled intersection special lane, the result that compared with conventional lanes, the traffic capacity of the signal-controlled intersection special lane is improved substantially can be computed out.

Description

technical field [0001] The invention relates to an intersection lane and a method for calculating its traffic capacity, in particular to a signal-controlled intersection special lane. Background technique [0002] Signal-controlled intersection is the bottleneck node of urban road traffic, and lane setting is a key factor affecting its operation level. The current setting is aimed at setting lanes with independent functions, but it is limited by the road space resources at intersections, especially for the most dense secondary branch road system in the urban road network. The width of the lane also often cannot add a standard lane that satisfies the passage of large vehicles. [0003] The types of lanes set at intersections are mainly obtained according to the following design methods: [0004] 1. According to the "Highway and Urban Road Design Manual", the width of each lane is mainly determined by the width of the vehicle body and the lateral safety distance, which is re...

AI Technical Summary

Problems solved by technology

[0010] For urban roads, due to the need to meet the traffic requirements of large vehicles such as buses, according to the previous concept that lanes must meet all types of vehicles, each lane must be set wide enough, which limits the wide use of narrow lanes

However, in actual operation, the most common vehicles on urban roads are small cars, and the lanes designed according to the traffic requirements of large cars are too wide for small cars, resulting in a waste of road resources
