The Conflict Analysis Of Intersection Under The Video Capture Information

As the hub of the urban road network, the intersection can directly impact on theoperating efficiency of the urban road network, which has been a major social concernin recent years, with the general deterioration of the traffic situation, the constraints ofthe operational status of the intersection to the urban road network operationalbenefits have become increasingly prominent. Therefore, how to improve theoperational status of the intersection, how to improve the overall operating efficiencyof the urban road network has got widespread attention.The pros and cons of the intersection operation benefits is mainly determined bythe intersection of the level of conflict, the intersection traffic conflict study is basedon the operating characteristics analysis of the intersection traffic flow, In this paper,which use the video image technology on urban roads intersection traffic flow toobtain the time-space information, then using the method of statistical analysis,cluster description to study the intersection traffic flow characteristics, in order todetermine the relationship between operating characteristics of the intersection trafficflow and traffic conflict, and to explain the intersection traffic flow operating rule.thereby application of the traffic flow theory, optimization control theory to researchon conflict mechanism of the intersection traffic flow, then we establish therelationship models between the degree of the intersection of mixing and the trafficlevel of conflict, the intersection of the level of conflict and the relationship of theintersection traffic flow characteristics, the intersection organization design andintersection operating efficiency, Then, based on the video image processingtechnology, we described the traffic running track and determined the intersection ofthe actual impact of the Vehicle-bicycle conflict areas, combined with the impact ofthe Vehicle-bicycle conflict, we create the capacity model of the vehicle flow.Determine the capacity of vehicle flow and bicycle flow under the impact of theVehicle-bicycle conflict. Then the paper research the conflicts of straight and turningleft vehicles and the conflicts of different driving directions straight-vehicle,Determine the capacity of vehicle flow under the impact of the Vehicle-vehicle conflict considering the impact of saturation flow rate and the speed.It is an explore to reduce traffic conflicts on the vehicle capacity of theintersection and improve the intersections efficiency of relevant research methods,research contents and research findings in this paper, Which can provide thetheoretical basis for the construction and management of the urban intersection.
