Problems solved by technology

However, due to the accuracy and efficiency of the algorithm, the control effects of most green waves are uneven; at the same time, due to the lack of feedback for the evaluation of control effects, the control schemes cannot be updated in time and adapt to the characteristics of traffic flow changes.

Abstract

The invention relates to an urban trunk green wave control evaluation method and a device. According to the method and device of the invention, a vehicle-mounted module installed on a test vehicle is adopted to acquire evaluation parameters; and based on the information processing of a handheld device and an evaluation algorithm in a calculation module, a green wave band control effect can be fast evaluated according to the travel time of a test route, the number of times of the parking of the test vehicle, and the saturation degree of an intersection. With the above method adopted, various types of trunk green wave control effects can be rapidly evaluated; control effect feedback can be obtained timely; an evaluation report can be generated; a control scheme can be optimized; urban traffic congestion can be alleviated; and driving safety can be ensured.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation, and in particular relates to a traffic signal control evaluation technology, a method and a device for evaluating the operation effect of green wave control for urban arterial roads. Background technique [0002] At present, as an important part of the urban road network, arterial roads undertake the main task of vehicle traffic. With the continuous increase of car ownership, arterial roads have become the hardest hit areas for traffic congestion. Therefore, the intelligent traffic signal control strategy of arterial roads has become one of the important means to alleviate traffic congestion. In various researches and inventions, the traffic control of urban arterial roads has been extensively explored, among which the green wave control of arterial roads is the most widely used and the best effect. However, due to the accuracy and efficiency of the algorithm, the control eff...
