【摘要】 为了缓解因交通流分布不均造成的交通拥堵,减少道路交叉口资源浪费,提出了基于时空资源组合的优化模型,分析了非饱和条件下信号控制交叉口单个进口道车道功能动态划分与通行时间分配的相互制约和转化关系。算例分析结果表明,该模型在流量需求动态变化范围内能得到效益最优的车道功能划分方案,有效地提高了交叉口时空资源的利用率。更多还原

【Abstract】 In order to alleviate the traffic jam that was caused by the traffic flow maldistribution,and reduce the waste of capacity of intersections as well,relations of mutual limitation and transition between dynamic lane assignment and running time allocation at an approach of signal control intersection were studied and an optimization model taking time space resources combination into account was put forward in this paper.The numerical test results show that the model can give an optimum benefit scheme based on dynamic lane functional partition within a given traffic demand range and effectively improve the utilization ratio of space time resources at intersections.更多还原
