Dynamic priority level-based bus signal priority method

Abstract

The invention provides a dynamic priority level-based bus signal priority method. The method comprises the steps of solving two problems. Firstly, a bus vehicle calculates the priority requirement ofan intersection according to the actual operation condition, namely the judgment on the level of the bus vehicle. Secondly, the priority potential is calculated based on the current traffic operationcondition of the intersection, namely the judgment on the level of the intersection. According to the method, the negative influence of the bus priority on the social traffic and the whole system is reduced, and the bus priority effect and the intersection traffic efficiency are improved. Therefore, the balance distribution of buses in all intervals can be realized, and the service level of the bus system can be improved.

Description

technical field [0001] The invention relates to a dynamic level bus signal priority method based on the combination of bus vehicle priority demand and intersection priority potential, and belongs to the field of bus signal priority control. Background technique [0002] With the continuous acceleration of China's urbanization process, the number of cities in China has grown rapidly, and the scale of cities has continued to expand. The total number of trips and travel distances of urban residents have shown a substantial increase. At the same time, significant changes have taken place in the urban traffic structure. The proportion of motorized travel has risen rapidly, the proportion of non-motorized travel has continued to decline, urban traffic congestion has intensified, traffic accidents have increased, energy consumption has increased, and the urban environment has deteriorated. Traffic has become a constraint for large and medium-sized cities. important factor in econom...
