Y型交叉口绿灯释放初期电动自行车对机动车的影响

Influence of E-bikes on Motor Vehicles in the Initial Stage of Green Light Release at Y-shaped Intersections

Y型道路交叉口属异形交叉口,趋于行驶车流角度,从而使灵活多变的电动自行车对机动车的影响较为突出.为研究Y型交叉口绿灯周期电动自行车对机动车的影响程度,统计了307组绿灯期电动自行车流量分布,确定了绿灯期0-10s为电动自行车释放初期,建立了基于Logistic逐步回归的电动自行车对机动车影响模型,通过实例验证了模型的有效性.结果表明,释放初期电动自行车的流量、占道间隙停车行为、自进口机动车第1车道驶入出口第2车道及自进口非机动车道驶入出口机动车第1车道的入侵行为对机动车影响显著,其中占道间隙停车行为对机动车影响最大.研究成果可为提高异形交叉口混合交通流通行效率、交叉口渠化设计及交通组织管理提供理论参考.

The Y-shaped road intersection is an irregular intersection,tending to the Angle of traffic flow,so that the flexible E-bike has a more prominent influence on motor vehicles.In order to study the impact of E-bikes on motor vehicles at Y-shaped intersections during the green cycle,307 groups of E-bikes during the green cycle were counted.It was determined that 0-10 s during the green period is the initial stage of the release of E-bikes,and the influence model of E-bikes on motor vehicles based on Logistic stepwise regression was established.The validity of the model was verified by an example.The results showed that the flow rate of E-bikes,the parking behavior between the occupied lanes,the intrusion behavior of the imported motor vehicles in the first lane into the exit lane and the non-imported motor vehicles in the first lane had a significant impact on the motor vehicles,among which the parking behavior between the occupied lanes had the greatest impact on the motor vehicles.The research results can provide theoretical reference for improving the efficiency of mixed traffic flow,channelization design of intersections and traffic organization and management at irregular intersections.
