Platoon Following Model and Simulation of Intelligent Connected Vehicles
With the development of intelligent connected vehicles,the intelligent and connected vehicles become the definite development trend.How to achieve safe and efficient traffic management and control in new industry model is an urgent issue.To study the platoon following in the intelligent connected environment and explore the rule-based vehicle queue formation mechanism,a platoon following model for intelligent connected vehicles was constructed based on the minimum safe distance model.The model based on 3 pieces of vehicle interaction rules:as close as possible,consistent speed,and collision avoidance.The model was established to perform the multi-objective optimization solving by using ride comfort and travel time as the comprehensive evaluation indicators.The platoon following model and optimization solving algorithm were programmed in SUMO simulation software.The simulation study was conducted for two-vehicle and five-vehicle traffic scenarios.The result indicates that the following vehicle can be in short time,at same speed,and keeping the minimum safety distance in the process of following the adjacent leading vehicle.It can simultaneously meet the requirements of riding comfort and optimal travel time.The simulation tests not only verify the feasibility of proposed platoon following model,but also validate the model scientific validity as the platoon fleet formation mechanism in the intelligent connected environment.To further illustrate the advantages of proposed model,the simulation tests of CACC platoon formation were conducted under the same simulation conditions.The comparative analysis on simulation result shows the vehicles driving more stably with the proposed platoon following model,thus ensuring the driving stability of whole platoon.
