摘要 为了分析自行车交通在机非划线分割道路断面内对机动车运行造成的干扰,对机非划线分割道路进行了实地调查,收集了交通流数据。采用累计曲线法,根据道路上机动车与自行车的交通流特征,建立了广义线性模型分析自行车对机动车运行延误的影响。分析结果表明:随着自行车密度的增加,部分自行车进入机动车道,导致机动车运行速度明显降低;机动车的运行延误随着自行车流量和机动车流量的增加而增加;机动车道数及自行车道宽度对机动车运行也产生显著影响。研究结果有助于理解自行车交通流如何影响机动车延误,对机非划线分割道路设计提供了参考信息。 In order to analyse the impact of bicycle traffic on vehicle operation on divided road,the field investigation on divided road is conducted and the traffic flow data are collected. By using cumulative curve method and according to the traffic flow characteristics of vehicles and bicycles on the road,a generalized linear model is developed to analyse the impact of bicycles on traffic delay of vehicles. The result shows that( 1) a part of bicycles travel into vehicle lanes as the bicycle density increases,resulting in the vehicle traffic speed decrease obviously;( 2) the delay of vehicle traffic increases as the traffic volumes of bicycle and vehicle increase;( 3) the number of vehicle lane and width of bike lane significantly affect the vehicle traffic. The finding can help understand the impact of bicycle traffic on traffic delay of vehicle,which provided the reference information for design of divided road.
