摘要
为利用可变车道增加交通高峰和紧急疏散时道路的通行能力,提出了动态车道反转的技术框架,以实现车道方向快速反转以适应动态交通流变化。建立了动态可变车道交通通行能力分析模型,分析了路段、交叉口和路网的通行能力。提出了整数线性规划和双层规划模型,以最大限度地通过可变车道提高路网的通行能力。结果表明:采用整数线性规划模型和主动式的可变车道管理策略,将使路网通行效率提高72%;采用双层规划模型模拟道路网络更能反映实际的交通运行状态。
In order to utilize reversible lane to increase the road capacity for peak hour traffic and emergency evacuation, the technology framework for dynamic reversible lane is proposed to achieve rapid lane reversal in dynamic traffic condition. A road capacity analysis model of dynamic reversible lane is built for analyzing the road capacity in road section, intersection and network. The integer linear programming and bi-level programming models are proposed to maximize the capacity of road network traffic with reversible lane. The result shows that （ 1 ） the integer linear programming model and the active management strategy will enable road network with reversible lane improve traffic efficiency by 72% ; （2） hi-level programming model for simulating road network is more suitable to reflect the actual traffic condition.
