大型客运枢纽行人标识导向系统设计优化模型及其解法

大型客运换乘枢纽往往具有复杂空间结构,行人标识导向系统对提高枢纽换乘服务水平、引导公共交通出行具有积极促进作用.基于复杂建筑空间特点和枢纽功能管理要求,行人导向标识布设问题本质上可以归纳为复杂决策问题.基于此,建立考虑公交优先和财政投入的多目标优化模型,采用基于距离的粒子群改进算法(DISMOPSO)对模型进行求解.在铁路上海南站枢纽新一轮行人标识导向系统布设的实例中验证优化模型和算法的有效性.实证表明,本研究给出的优化模型与算法可以为大型客运换乘枢纽行人标识导向系统设计提供借鉴与帮助.

Optimization model for pedestrian-oriented signage system in large passenger hub and the DISMOPSO algorithm

Cope with complex architectural spaces in large passenger transfer hub, pedestrian-oriented signage system in hubs has a positive role in improving the service level of transfer and encouraging travelers to choose public transport. Based on the complexity features and requirements of hub management function, the design of pedestrian-oriented signage system essentially can be summarized as complex decision problems. Aiming at this problem, this paper develops a multi-objective optimization model. The improved particle swarm algorithm based on distance (DISMOPSO) is used to solve the model. In the project of Shanghai South Railway Station pedestrian-oriented sign system design, the mathematical model and the algorithm are used to verify their logical and effectiveness. The empirical results show that optimization models and algorithms can provide reference and help in the design of pedestrian-oriented signage system in large passenger hub.
