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 is a green wave control and evaluation method and device for urban arterial lines. The invention obtains evaluation parameters through a vehicle-mounted module installed on the test vehicle, and uses the information processing and evaluation algorithm in the calculation module of the handheld device to evaluate the green wave zone based on the test line travel time, the number of test vehicle stops, and the intersection saturation. Quickly assess control effectiveness. The above method can be used to quickly evaluate the green wave control effects of various types of trunk lines, obtain timely feedback on the control effects, and generate evaluation reports to achieve the purpose of optimizing control plans, alleviating urban traffic congestion, and ensuring driving safety.

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...
