我们提出了一个灵活的公共交通网络设计模型，它优化了社会访问目标，同时保证系统的成本和运输时间保持在其当前水平的预设范围内。该模型的目的是找到一组微小的，立即修改现有的公交网络，可以让更多的社区获得所选择的服务，同时对当前网络的运营商成本和用户成本的影响最小。设计决策包括重新分配现有资源，以调整线路频率和容量。我们提出了一种混合禁忌搜索/模拟退火算法的解决方案，这个优化模型。作为一个案例研究，我们应用该模型的问题，提高公平获得初级卫生保健设施在芝加哥大都市区。该模型的结果表明，有可能实现更好的初级保健获得公平，通过重新分配现有的巴士和实施快车运行，同时离开整体服务水平相对不受影响。
We present a flexible public transit network design model which optimizes a social access objective while guaranteeing that the system’s costs and transit times remain within a preset margin of their current levels. The purpose of the model is to find a set of minor, immediate modifications to an existing bus network that can give more communities access to the chosen services while having a minimal impact on the current network’s operator costs and user costs. Design decisions consist of reallocation of existing resources in order to adjust line frequencies and capacities. We present a hybrid tabu search/simulated annealing algorithm for the solution of this optimization-based model. As a case study we apply the model to the problem of improving equity of access to primary health care facilities in the Chicago metropolitan area. The results of the model suggest that it is possible to achieve better primary care access equity through reassignment of existing buses and implementation of express runs, while leaving overall service levels relatively unaffected.
