Abstract

Netheradays planning of metropolitan areas considers to improve quality of life of their inhabitants and urbanmobility is one of the main concerns. Studies point out that investments in public transportation and other modes are aimedat the overall improvement of mobility. However, there is a gap in proper tools for optimizing public transport networks.In fact, network optimization is an NP-Hard problem and there are usually many conflicting objectives that need to beoptimized simultaneously. This paper proposes the use of manyobjective evolutionary algorithms to address the problem ofpublic transport networks optimization, focusing on metropolitan bus lines. The proposal consists in optimizing the position of bus stops and consequently obtaining new routes that pass through these stops in order to minimize the average travel time, the time spent between origin / destination and the variance of distance between the stops. To evaluate our proposal, a simulator was used to simulate the behavior of different passenger profiles in an urban area and the results were compared between the lines obtained by the optimization process and existing bus lines in the city of Sao Paulo. According to our results, optimized bus routes have mean travel time 22% less than the existing route and the time spent between origin/destination has decreased up to 18%.
通过考虑网站的替代位置优化公共交通网络
如今,大都市地区的规划都会考虑提高居民的生活质量,而城市交通则是主要关注点之一。研究指出,对公共交通和其他交通方式的投资旨在全面提高流动性。事实上,网络优化是一个 NP-困难问题,通常有许多相互冲突的目标需要同时优化。本文建议使用多目标进化算法来解决公共交通网络优化问题,重点是大都市公交线路。该建议包括优化公交站点的位置,进而获得经过这些站点的新线路,以最大限度地减少平均旅行时间、起点/终点之间的时间以及站点之间的距离差异。为了评估我们的建议,我们使用模拟器模拟了城市地区不同乘客的行为,并将优化后的线路与圣保罗市现有的公交线路进行了比较。根据我们的结果,优化后的公交线路比现有线路的平均旅行时间减少了 22%,在起点/终点之间花费的时间最多减少了 18%。
