我国部分城市正在进行有轨电车建设,迫切需要建立一套科学实用的选线体系,为规划设计人员提供可依据的尺度和方法.依托具体的有轨电车建设项目,从道路条件、客流条件、城市发展适应性、成本效益4方面明确了有轨电车选线准则,建立了有轨电车路线选择测度模型;该模型以影响参数为因素指标集,以路线方案为论域集,构建了有轨电车路线方案决策矩阵,应用[0,1]线性变换将其标准化;充分考虑专家知识经验以及数据本身蕴涵的信息综合确定影响参数的权重,并将标准化决策矩阵与参数权重相结合构造了加权标准化决策矩阵;基于运筹学中的格序决策方法确定了有轨电车路线方案的正负理想方案,通过计算路线方案与正负理想方案的欧氏距离以及路线方案的综合差异值来确定有轨电车最优路线方案.最后,以某市有轨电车线路规划说明了本模型的科学性与有效性.
In some cities of our country, the construction of the tramcar is underway and there is an urgent need to establish a scientific and practical route selection system to provide the basis for the planning and design personnel.Relying on the specific tramcar construction project, from the road conditions, passenger flow conditions, Urban development adaptability and cost-effectiveness 4, the tram line selection criteria are established and the tram route selection measurement model is established. The model takes the influence parameter as the index set of indicators and the route scheme as the domain set, Which is standardized by [0, 1] linear transformation. The weight of influential parameters is determined by taking full account of the expert knowledge experience and the information contained in the data. The standardization decision matrix and the parameter weight are combined to construct the weighted normalization Decision matrices. Based on the grid decision method in operation research, the positive and negative ideal solutions of the tram route plan are determined. By calculating the Euclidean distance between the route plan and the positive and negative ideal plan and the comprehensive difference value of the route plan, The best route plan.Finally, the city tram route planning shows that the model is scientific and has Sex.
