摘要

本研究旨在开发一种迁移城市批发市场的方法,目的是通过提高交通效率来缓解中心区域的拥挤状况,并使其成为无污染区域。本文提出了一个双层优化框架,在上层追求地方当局的目标,即相对于确保物有所值的支出,实现福利效益最大化。下层框架考虑了零售商对批发市场搬迁的反应,允许他们选择采购地点。下层问题还模拟了商用车辆和私家车辆的路线选择,以衡量由此造成的街道拥堵。针对印度尼西亚万隆的情况,采用整数粒子群优化算法解决了这个双层问题。结果显示,搬迁批发市场可将市中心的交通效率和污染水平提高约 14%。整个城市的交通速度也提高了 6.6%,污染水平也略有下降。作为一项战略,市场搬迁将显著提高效率和污染水平,但必须进行仔细规划和评估,否则市中心以外的排放量可能会增加。

Analysing wholesale market development strategies for decongesting city centre considering retailers’ procurement choices

This research is aimed at developing a method for relocating wholesale markets in a city with the objective of decongesting the central area by improving the traffic efficiency and to make it pollution free. This paper proposes a bi-level optimisation framework pursuing the local authority’s objective of maximising welfare benefits relative to the spend ensuring good value for money at the upper level. The lower-level framework considers retailers’ response to the relocation of wholesale markets allowing them the choice of procurement location. The lower-level problem also models the route choice of commercial vehicle traffic as well as the private vehicle traffic to measure the resulting on-street congestion. The bi-level problem has been solved with integer Particle Swarm Optimisation algorithm for the case of Bandung, Indonesia. The results show that relocating wholesale markets improves the city centre traffic efficiency and pollution level by about 14%. Traffic speeds over the entire city also improve by up to 6.6% and the pollution levels marginally would drop too. Market relocation as a strategy would significantly improve the efficiency and pollution levels but must be carefully planned and evaluated otherwise the emissions outside of city centre could increase.
