Research On Coordinated Vehicle Control Strategy For Connected Vehicle Dedicated Lane

With the improvement of intelligent,networked and automation level of automobile industry.After the network of vehicles,there is a problem of traffic efficiency decrease caused by the mixed driving of two heterogeneous vehicles,automatic driving and manual driving.In this regard,the measures to improve the operating efficiency are proposed to separate the two heterogeneous traffic flows in the special lane for networked vehicles.However,the current research only considers the lane users of autonomous vehicles,and fails to take into account the technical potential of networked human-driven vehicles equipped with collaborative adaptive cruise control system.Through the lanes to set up and running management factor analysis,based on snatched vehicle market penetration after setting the threshold value reaches lanes for vehicle fleet to further improve the efficiency of lane,to made the vehicle on the basis of bike trail formation strategy research,finally using the SUMO to snatched the vehicle lanes to evaluate operating efficiency,It provides a theoretical basis for the future management of dedicated lanes for networked vehicles.Firstly,this paper defines the types of networked vehicles from the aspects of vehicle automation level and networked communication,and gives the definition and applicable conditions of the dedicated lane for networked vehicles.Based on the analysis of the design form of dedicated lanes and the elements of lane operation management,the basic form of lane setting and the frame of fac tors affecting lane efficiency are given.The basic form of vehicle control in the Internet of Vehicles environment is defined,and how vehicle formation affects the efficiency of dedicated lanes is analyzed.Then,based on the analysis of operating efficiency and formation performance of dedicated lanes,the formation problem of networked vehicles is analyzed to clarify the characteristics of networked vehicles formation,determine the control strategy of vehicle formation,divide vehicle control areas acc ording to the conditions of basic lanes,and formulate vehicle simulation generation and formation rules.The cooperative control strategies with different proportions of the two kinds of connected vehicles under the fixed market penetration rate are propo sed.And based on prospect theory made artificial pilot collaborative behavior decision model,in the process of actual driving following and lane changing model is amended,analysis its interaction with automatic driving vehicle,the interaction between b oth collaborative queue strategy,vehicle interaction control process calculation method are given,furthermore puts forward vehicle queue in the driveway running stability and efficiency evaluation method.Finally,the proposed lane management strategy and formation strategy are verified by using SUMO-Veins simulation software.The results show that the set of dedicated lanes for networked vehicles can play its role when the market penetration rate reaches 30%,and the performance of the lane decreases whe n the market penetration rate reaches 45%,which is mainly reflected in the turning point of the average running speed of vehicles.After that,the vehicle formation drives in the dedicated lane in accordance with the 50% market penetration rate.The improvement of overall traffic efficiency is about 58.8% without dedicated lanes.
