摘要
为了揭示匝道控制对高速公路通行能力的影响,基于接受间隙理论综合考虑加速车道对车辆汇合的影响得出了高速公路干道流量与匝道流量间的关系模型, 并且对各种服务水平下的实际流量进行了具体的计算,为匝道控制和高速公路管理提供了依据。
In order to figure out the impact of ramp control on the traffic capacity on freeway, a functional model of the relationship between the traffic flow on freeway and that on ramp is developed based on gap-acceptance theory with consideration of the impact of the acceleration lane. Furthermore, numerical examples are presented in detail under several service levels, which provides foundation for ramp-control and freeway management.
