Embodiment Construction

[0032] Below in conjunction with accompanying drawing and embodiment the present invention will be described in further detail:

[0033] I. design concept and main technical features of the present invention

[0034] The invention relates to a method for controlling mixed traffic signals at a single intersection using a self-programmed computer program. The self-compiled computer program is loaded into the signal machine, and the signal machine runs the self-compiled computer program to realize the control method of mixed traffic signals at a single intersection.

[0035] The preparation of computer programs involves the calibration method of motor vehicle conversion coefficient, the calibration method of bicycle conversion coefficient, the optimization method of signalized intersection timing based on traffic intensity, the determination method of bicycle phase green light early cut-off time and the induction control of variable unit green light extension time method. In or...

Abstract

This invention relates to one single cross mixture traffic signal control method by use of computer program, which comprises the following steps: summing up the automobile car number relative to standard car number by use of the computer program of the formula method and for the number of bicycle number; summing up each channel traffic flow standard car number per hour by use of data process program; signal machine judges and selects whether for single point time control type or signal sense control type or single optimization type for each type signal optimization scheme.

Description

technical field [0001] The invention relates to a method for urban traffic management control, in particular to a control method for mixed traffic signals at a single intersection. Background technique [0002] With the development, application and improvement of traffic control systems such as TRANSYT (UK in the 1960s), SCOOT (UK in the 1970s) and SCATS (Australia in the 1980s), it marks the relevant theories and methods of urban traffic control systems. And the implementation technology has reached a quite mature level in developed countries. Although there are still many people engaged in research in this field in these countries, it is difficult to break through the existing theory and method system. In our country, with the introduction and application of foreign traffic control systems (at present, dozens of cities have introduced foreign traffic control systems), relevant theoretical workers and engineering technicians have applied the key theories and methods of thes...
