Studies On The Influence Of Comprehensive Corridor Construction On Road Capacity

Since the reform and opening-up in China for more than 30 years,the economy has been rapidly upgrading,the scale of urbanization has been expanding,and the demand for public infrastructure such as power supply,heating,water supply,exhaust and communication,which is based on urban development,Growth,integrated corridor This emerging municipal approach is adopted by more and more cities,but the construction of integrated corridors,excavation of the road,but also caused the interference of road traffic.In this paper,the comprehensive management of Kunming Road,Xi'an,as an example,combined with VISSIM simulation software,the road capacity of the specific study for the integrated corridor construction and construction sections of the traffic organization to provide a certain reference.Firstly,this paper analyzes the impact of the construction of the integrated corridor on the traffic.Based on the characteristics of the road and the characteristics of the vehicle,the traffic simulation platform based on VISSIM is introduced,and the traffic simulation is used to study the traffic The impact of capacity.Secondly,the research on the traffic capacity of the road sections is carried out,and the main factors influencing the traffic capacity of the road sections are put forward.The reduction coefficient of the traffic capacity is obtained from the aspects of the length of the construction area,the proportion of the large car and the speed limit of the construction area.The basic capacity of the construction section is obtained.Based on the basic capacity,the actual capacity of the road section is calculated and compared with the traffic capacity under the normal road section,which shows the influence of the construction of the integrated corridor on the traffic capacity.Finally,the traffic capacity of the signal intersection is studied.This paper analyzes the main factors influencing the traffic capacity of the signalized intersection,and puts forward the calculation of the traffic capacity of the signalized intersection with the saturated flow rate model.The traffic simulation is carried out at the intersection after the construction of the integrated corridor,and through the Kunming Road and Seoul South Road The intersection of the traffic survey,the maximum allowable traffic volume concept to simulate the middle of the Wai Wai and side of the fence under the conditions of the maximum traffic volume,and no encirclement at the intersection of traffic volume comparison,Effect of Construction of Comprehensive Corridor on Capacity of Intersection.
