由于国内经济飞速发展,车辆的社会保有量越来越高,对城市的交通道路和原有的城市建设都提出了挑战。为满足城市交通需要,完善城市的交通路网结构,促进物流行业的发展,越来越多的城市选择建立高架立交桥、城市轻轨等形式。但是在城市中进行大规模的建设需要考虑到时间效率和噪音污染等多种因素的影响。 Due to the rapid development of the domestic economy, the social possession of vehicles is getting higher and higher, posing challenges to the urban traffic routes and the original urban construction.
