| In recent years,the number of cars in China has increased sharply,but the parking space has increased slowly,which cannot meet the parking demand.On-street parking is widely used as an effective means to alleviate the parking problem.When the on-street parking solves the parking problem,it also interferes with the motor vehicle flow in the road.The interference of on-street parking to the motor vehicle flow in the road under the non-mixing condition was further expanded.In this paper,the vehicle flow with the on-street parking berth section is studied,and the impact on the non-mixed conditions is analyzed.This paper first expounds the setting principle and management of on-street parking,the driver’s choice behavior,etc.;analyzes the three elements of traffic flow;analyzes the characteristics of drivers,cars and non-motor vehicles;The mutual interference in the detailed analysis is carried out,focusing on the impact of retrograde non-motor vehicles on traffic.By analyzing the data in the captured video,the blocking interference is classified and the influence of individual factors on the speed of the vehicle is quantified.The density-flow model is used to obtain the approximate road capacity of the research section,and compared with the calculated road traffic capacity without onstreet parking and non-motor vehicles,the degree of influence of on-street parking and nonmotor vehicles on road capacity is made a preliminary judgment.Combining the theoretical analysis with the captured video,the main factors affecting the traffic velocity are determined.A multivariate regression analysis is used to establish a nonlinear model of traffic velocity.Based on the conflict theory,the road capacity model is established.In this paper,a single-lane road with on-street parking berths and non-mixed vehicles is taken as the research object.The vehicle flow velocity model and road traffic capacity model are established.The relevant parameters are determined by VISSIM simulation. |
