摘要
针对中小城市临时交通管制措施下出现的交通拥堵状况,应用微观交通仿真软件TransModeler建立拥堵区域路网模型。运用动态交通组织手段来实现拥堵区域交通总量控制,均衡路网交通压力。以曲靖市中心城区拥堵区域动态交通组织优化为实例,通过仿真结果对方案实施前后的各拥堵路段的交通流运行状况进行评价,证明了流量调控方法对缓解拥堵区域交通状况具有一定的科学实效性。
For the traffic jams under the temporary traffic-control measures in small and medium-sized city,microscopic traffic simulation software TransModeler is applied for establishing regional network under the traffic congestion.Dynamic model of traffic organization means is used to realize total amount control of regional traffic congestion,and balance traffic pressure of network.And dynamic optimization of traffic congestion of the downtown area in Qujing city is took for example,it is through simulation results of optimizing organization before and after to evaluate traffic flow of each of road traffic congestion.It proves that flow adjustment methods can ease the regional traffic congestion and it has certain scientific effectiveness.
