Integrated main line intersection group space-time resource allocation method capable of lowering delay and emission

Abstract

A coordinate signal timing dial optimization method capable of lowering vehicle delay and traffic emission is applicable to main line intersection groups with (without) left-handed rotation short lanes. On the basis of impact analysis of coordinate signals on the main line traffic flow, short-lane space optimization is considered, and a main line intersection group space-time resource allocation optimization model is constructed, and the main line intersection group signal timing dial optimization model is constructed for determining the short-lane space. In order to evaluate the operating efficiency and the environmental conditions of main line intersection groups, three performance indexes of the specific form are provided, and a lane group average traffic delay estimation method and a traffic light period emission factor calibration method are improved. Then, technological application processes for models and methods are given for various conditions. By means of traffic simulation software VISSIM and programming software MATLAB, a computational example is used for explaining the technological application processes. A result shows that the novel method can integrally allocate time-space resources for main line intersection groups, the minimization of vehicle delay and traffic emission is achieved, and the method can be widely applied to signal timing dial design and optimization.

Description

technical field [0001] The invention belongs to the field of intelligent traffic control, and relates to a time-space resource allocation method applicable to an integrated arterial intersection group with (without) short lanes, which reduces vehicle delay and traffic emissions. Background technique [0002] In recent years, the number of motor vehicles in some large and medium-sized cities has continued to increase sharply, resulting in frequent and prolonged traffic congestion. At the same time, exhaust emissions from motor vehicles have led to continuous deterioration of the travel environment and living environment. From the perspective of traffic management and control, improving the efficiency of road network operation, shortening the travel time and delay of motor vehicles, and reducing the exhaust emissions of motor vehicles have become a hot issue that many scholars and engineers are concerned about. [0003] In the urban road network, there is a strong correlation ...
