Single-point control benefit evaluation method of road traffic signal

Abstract

The invention provides a single-point control benefit evaluation method of a road traffic signal. By the single-point control benefit evaluation method, quantized data can be provided, and the controlbenefit of a road intersection signal can be objectively evaluated. The signal-point control benefit evaluation method of the road traffic signal comprises the steps of S1, detecting an index which can represent a traffic running condition of a road intersection; S2, detecting a calculation formula of the index, and calculating a single index value of the index; S3, building a corresponding relation between a single index value range and a value range of a single-point control benefit evaluation index; S4, calculating a corresponding single-point control benefit evaluation index by a linear interpolation method; and S5, evaluating different emphasis points of traffic signal single-point control benefit with regard to different traffic time frames, and setting different weights for each index at different traffic time frames. On the basis of the sum of each single-point control benefit evaluation index and the corresponding weight, the control benefit integral index corresponding to asingle intersection is calculated by employing a weighted mean method.

Description

technical field [0001] The invention relates to the technical field of road intersection signal control effect evaluation, in particular to a road traffic signal single-point control benefit evaluation method. Background technique [0002] With the widespread application of intelligent transportation technology, traffic signal control technology has been developed on a large scale. According to statistics, by the end of 2016, there were 74,000 signal lights controlling intersections across the country, and the light control rate reached 43.1%. There are various types of signal control systems used in various places, and the control methods include timing, induction, self-adaptation, trunk line coordination, regional control, etc., and the application level is uneven. In order to control and manage traffic lights reasonably, it is necessary to apply traffic lights The effect and adaptability are evaluated and verified; due to the lack of a unified traffic signal control bene...

Problems solved by technology

There are various types of signal control systems used in various places, and the control methods include timing, induction, self-adaptation, trunk line coordination, regional control, etc., and the application level is uneven. In order to control and manage traffic lights reasonably, it is necessary to apply traffic lights The effect and adaptability are evaluated and verified; due to the lack of a unified traffic signal control benefit evaluation specification in China, the current evaluation of the rationality of road intersection signal management is mainly to start with manual observation of the congestion situation of each road intersection, from each Judging the signal management of road intersections from the angles of vehicle queuing at each intersection and the number of vehicles passing through each green light, etc., but the methods used are all subjective judgment methods, lacking reasonable and general quantitative analysis methods. As for the inability to establish a unified evaluation system, unified and scientific control and management of traffic signals at intersections
