Embodiment

[0123] Embodiment: A single-point off-line optimization system for traffic signals is composed of an intersection determination module, an adaptive strategy module and a fixed-scheme strategy module.

[0124] A single-point offline optimization method for traffic signals, specifically as follows:

[0125] Collect the geomagnetic data of single-point intersections, and the intersection judgment module judges and distinguishes the types of single-point intersections based on the integrity of the geomagnetic data, and determines different optimization strategies for optimization according to the integrity of the geomagnetic data:

[0126] (i) For single-point intersections with complete geomagnetic data or incomplete but repairable geomagnetic data, call the adaptive strategy module to perform adaptive optimization strategy control to adjust the timing with traffic;

[0127] (ii) For single-point intersections with incomplete geomagnetic data and irreparable geomagnetic data, the...

Abstract

The invention relates to a single-point offline optimization system and method for traffic signals, and the system and method can formulate an appropriate optimization strategy according with a current intersection based on the data condition of the current intersection, and optimize the signal timing through the data information. Single-point intersections are classified according to intersectiondata conditions, different offline optimization strategies and methods are adopted for different classifications, and two single-point offline optimization strategies are defined, so that data resources can be utilized more effectively, and efficient optimization of the single-point intersections is realized.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a system and method for single-point off-line optimization of traffic signals. Background technique [0002] With the improvement of people's living standards, the urban population is increasing day by day, the number of cars is increasing, the pressure on urban traffic is increasing, traffic jams are becoming more and more serious in large and medium-sized cities, and the contradiction between economic growth and traffic congestion is becoming increasingly prominent. Traffic conditions have seriously restricted economic development. According to incomplete statistics, China's annual economic loss due to traffic congestion is about 200 billion yuan. Urban traffic problems have become the focus of common attention at home and abroad, and are related to the sustainable development of cities. [0003] Traffic congestion often occurs at road intersections. Reasonably alloca...
