道路交叉口是人流、车流的比较集中的地方,也是经常发生交通事故的地方,将渠化设计应用在道路交叉口设计中,可以有效的降低交通事故发生的概率。改善交通问题,可以缓解交通压力,提高道路的通行能力,保证道路的通畅。道路交叉口的渠化设计的方法很多,根据不同的道路条件需要选择不同的方法,而且还要遵循平面交叉口渠化的原则,这样才能实现提高道路的利用率。 Road intersection is a place where people and traffic are more concentrated. It is also a place where traffic accidents often occur. Using canal design in road intersection design can effectively reduce the probability of traffic accidents. Improving traffic problems can relieve traffic pressure, enhance the capacity of roads and ensure smooth roads. There are many ways to design canalization at road intersections. Different methods should be chosen according to different road conditions, and the principle of canalization at plane intersections should be followed in order to improve the utilization of roads.
