为有效缓解因潮汐现象所导致的交通拥堵和道路资源闲置并存的问题,在考虑车道数对路段单向通行能力影响的基础上研究可变车道优化设置方法。该方法在确保可变车道实施过程中轻交通流方向正常通行的前提下,基于非均衡经济学理论的价格-数量调节,以系统总出行时间最小为目标构建可变车道优化的混合整数双层规划模型,并采用粒子群优化算法对模型进行求解,以算例的形式验证模型和算法的有效性。研究结果表明:从系统层面优化可变车道设置能够充分利用轻交通流方向闲置的道路资源来提高重交通流方向路段的容量,从而改变其行程时间函数,进而调节流量在路网上的分布并均衡各路段的饱和度;使道路网络结构...

In order to effectively alleviate the coexistence between traffic congestion and road resource idle caused by the tidal phenomenon, the variable lane optimization setting method was studied considering the influence of lane number on road unidirectional capacity. In this method, on the premise that the normal passage of the light traffic flow direction was ensured during the variable lane implementation process, the mixed integer bi-level programming model for variable lane optimization was established based on the price-quantity regulation of ...
