通过对郑州市不同等级道路对应的小区进行相关变量测量并结合相关值得出结论,高等级道路对应的小区饱和车头时距较低,平均行程车速较高。按小区模式和规模向城市规划部门、从开源和节流两方面向交通管理部门分别提出了合理化建议。 Through the relative variable measurement of the communities corresponding to the different grades of roads in Zhengzhou and the correlation values, it is concluded that the saturation time of the saturated areas of the districts corresponding to the high-grade roads is relatively low and the average speed of traveling is higher. According to the district pattern and scale to the city planning department, from the open source and throttling two aspects to the traffic management department put forward reasonable suggestions.
