影响城市畅通的因素很多,人、车、路、环境无一不重要。任何一个环节都会影响甚深,其中作为“交通基础设施”对安全畅通起关键作用。路的设计合理科学与否,其交通运行状况直接影响到出行的质量,影响交通的安全、畅通、环保、有序、便捷及其效率化。仅这一问题就涉及到城市规划、城市建设等部门,而非公安交管部门一家所能解决的。 Many factors affect the smooth city, people, cars, roads, the environment is not important. Any one link will have a profound impact, which as “transport infrastructure ” play a key role in security flow. The design of the road is reasonable and scientific or not, the traffic status of the road directly affects the quality of the travel, which affects the safety, smoothness, environmental protection, orderliness, convenience and efficiency of the traffic. Only this issue involves the city planning, urban construction and other departments, rather than the public security departments can solve one.
