Multi-index based intersection signal timing plan evaluation method

Abstract

The invention provides a multi-index based intersection signal timing plan evaluation method, which belongs to the field of traffic control technology. The method comprises the steps of collecting traffic parameters generated by running a current signal timing plan and selecting a plurality of evaluation indexes in the traffic parameters; based on a preset normalization function, subjecting the plurality of evaluation indexes to normalization to obtain corresponding evaluation index values; based on a preset evaluation index weight algorithm, calculating weight values of the plurality of evaluation indexes; and obtaining the evaluation result of the intersection signal timing plan based on the plurality of evaluation index values and the weight values of the plurality of evaluation indexes. By the use of the plurality of independent and uncrossed evaluation indexes, and by normalization of the various evaluation indexes to eliminate the problems caused by differences in the dimension, the authenticity of problems in the signal timing plan that are reflected by the various evaluation indexes is improved, and with combination of the weight value of each index, the obtained evaluation result of the signal timing plan can be very accurate.

Description

technical field [0001] The invention relates to the technical field of traffic control, in particular to a multi-indicator-based evaluation method for an intersection signal timing scheme. Background technique [0002] At present, the increasing congestion of urban traffic has attracted social attention, which has brought unprecedented pressure to urban traffic management. In the management of urban road intersections, the use of intersection signal timing schemes can effectively regulate the traffic at intersections. Therefore, the role of traffic signal timing design is becoming more and more significant. However, the current timing scheme often has some problems in practical application, which leads to low traffic efficiency at road intersections. Therefore, it is necessary to evaluate the traffic signal allocation in order to optimize the timing scheme according to the evaluation results. [0003] At present, methods for evaluating traffic signal timing schemes general...
