摘要:
通过调查历史街区交通拥堵问题,发现在街区主要道路拥堵不堪时,很多支路却未被充分利用.本文通过分析单向交 通的特征和历史街区实施单向交通的合理性,提出将支路的单向交通组织作为缓解历史街区交通压力的有效管理措施.建立了基于历史街区特色的道路阻抗函数,并以研究区域路网出行时间最短为目标通过仿射尺度法进行交通分配,最后以西安市湘子庙历史街区为例,应用Transcad 软件反推得到出行OD 矩阵,提出路网单向组织方案,得到实施单向交通后的路网流量分配值.将优化方案与现行方案进行比较表明,历史街区实施单向交通组织后路网通行能力得以提高,交通质量得到明显改善.
Abstract:
By investigating the traffic jams and congestion of historic district, the authors find that many branch roads are left unused when traffic jams occur in the main road. This article suggest one-way traffic organization of branches as the effective management measures to relieve the traffic pressure by analyzing the characteristics of one-way traffic and rationality of implementing one-way traffic in historic district. This article estimate impedance function based on the characteristics of road in historic district, and use the affine scaling algorithm to carry on transportation assignment by the shortest travel time of the study area road network as the goal establish directional. This article finally take the historic district of Xiangzi Temple in Xi’an as an example, obtain OD one-way traffic Matrix by the Transcad software, present the scheme of one-way traffic organiz ation and get the flow assignment. Comparing the optimized result with present scheme, it shows that the road network capacity and the traffic quality of historic district are improved significantly after the implementation of one-way traffic.
