伴随经济的快速增长,城市化进程的不断加快,城市人口数量不断扩大增加,汽车工业的飞速发展,产量销量持续的增加,城市居民物质生活的极大提高,城市私家车数量持续快速上升。此种状况下使得城市机动车保有量也在不断扩大,但城市区域空间有限,城市道路资源远远不能满足不断增长的车辆通行及停驻的需求,造成交通拥堵的现象日益加剧。城市交通拥堵不但影响交通参与者的出行时间,拥堵停滞增加了能源消耗,拥堵停滞的延时排放加重了空气污染,拥堵造成的事故带来巨大的经济损失,成为阻碍城市发展的顽疾。城市交通拥堵已成为世界性难题。国内外存在道路交通拥堵的城市都尽力采取措施去解决或缓解拥堵状况,但收效却不明显。本文通过对城市道路造成拥堵的各种因素进行分析,查找造成道路拥堵的根源,并提出相应的解决办法。
With the rapid economic growth, the process of urbanization continues to accelerate, the urban population continues to expand and increase, the rapid development of the automobile industry, production and sales continued to increase, greatly improving the material life of urban residents, the number of urban private cars continued to rise rapidly. Under such circumstances, the number of motor vehicles in urban areas is also constantly expanding. However, due to the limited space in urban areas, urban road resources can not meet the ever-increasing demand for vehicular traffic and parking, which aggravates the phenomenon of traffic congestion. The congestion of urban traffic not only affects the travel time of traffic participants, but also increases the energy consumption due to the stagnation of congestion. The delayed discharge of congestion aggravates the air pollution. The traffic accident caused by congestion brings huge economic losses and becomes a stubborn obstacle to urban development. Urban traffic congestion has become a worldwide problem. Cities with road traffic congestion at home and abroad all try their best to take measures to solve or alleviate the congestion situation, but the effect is not obvious. This paper analyzes the various factors causing congestion in urban roads, finds the root causes of road congestion, and puts forward corresponding solutions.
