Research On The Impact Of Entering Vehicles On The Urban Road Access With Bus Lane

With the rapid development of China's national economy,there are more and more families can own cars.As a result,the number of private cars increases every yare,and the trend of motorization of residents' travel modes is becoming increasingly obvious.This has aggravated the traffic pressure of China's urban road network and will become more severe in the future.In order to alleviate the urban traffic problems caused by the increase in motor vehicle travel volume,many cities in China have begun to set up bus lanes.However,due to many factors such as urban spatial layout and urban demand,many cities usually set up access ports on road sections with bus lanes to meet the traffic demand of office,medical,commercial,etc.Usually,the opening period of the bus lane is also the peak hour of the city commuting.At this period,the mutual interference between vehicles that want to pass through the access port and vehicles on the main road,the non-motor vehicle is inevitable.This will affect traffic operation in the access section and even lead to traffic congestion throughout the road.Therefore,it is necessary to study the impact of vehicles that want to pass through the access port on the traffic operation of the access port from two levels during the opening period of the bus lane.The first is the conflict between the vehicles that want to pass through the access port and the bus and how this conflict affects the vehicles in other lanes.The other is how the vehicles that want to pass through the access port interact with the non-motor vehicle during the crossing of the non-motor vehicle lane.This paper relies on the Humanities and Social Sciences Fund of the Ministry of Education of China,“Research on the Mechanism and Management Strategy of Traffic Congestion at the Entrance of Parking Facilities Based on Multi-source Data Fusion(Approval No.:19YJAZH011)"and the Yangzhou University Cultivation Fund,"Traffic congestion mechanism and optimization method for entrance of off-street parking facilities under multi-factor coupling".Through surveys,data analysis and modeling,the research on the mechanism of the vehicles entering the urban road access port with bus lanes is carried out,including the following contents:investigation and characteristic analysis of influence of vehicles that want to pass through the access port on access port;analysis of the influence of vehicles that want to pass through the access port on the vehicles in other lanes of the road bus lanes;analysis of the influence of vehicles that want to pass through the access port on the non-motor vehicle lane.Firstly,according to different types of urban road access ports and access roads,the traffic characteristics and influencing factors of the access road sections with bus lanes are analyzed from the aspects of road conditions,traffic conditions,and traffic management.At the same time,in order to facilitate the study of traffic impact characteristics,a corresponding traffic survey plan was developed and the data obtained from the survey is analyzed.Secondly,according to the basic characteristics of vehicles that want to pass through the access port,its driving behavior and position before leaving the road are analyzed.The influence of the opening and closing periods of the bus lane on the vehicles that want to pass through the access port are analyzed.Based on the arrival characteristics of the bus and the driving characteristics of the vehicle,the traversable gap model for the vehicles that want to pass through the access port is constructed;the first following vehicle delay time model is established based on the acceptable gap of the vehicles that want to pass through the access port;the arrival rate of the bus and vehicles in the main road are selected as main parameters to build the main road traffic delay time model.The models proposed in this section are all simulated.Finally,the basic characteristics of the non-motorized traffic flow in the access section are analyzed,and the game theory is selected to study the non-motor vehicle lane of the access section.The basic concepts and research principles of game theory are introduced in detail.The delay time of non-motor vehicles and the vehicles that want to pass through the access port are selected as utility value to build the game model.The evolution mechanism of decision-making behaviors of the vehicles that want to pass through the access port and non-motor vehicles is analyzed and simulated.
