Modelling and Analysis on Commuting Behaviors Considering Dedicated Autonomous Vehicle Lane and Combined Management Strategy
Considering the coexistence of new multi-mode commuting modes under the background of autonomous driving,a dedicated lane for autonomous vehicles was set up,that is,a two-lane traffic system in which traditional cars and autonomous vehicles travel separately.Based on the bottleneck model,the effects of the combined management strategy of tradable credit scheme and encouraging carpooling on the credit price,commuters'choice of travel mode and endogenous penetration rate of autonomous vehicles were analyzed before and after the implementation of the combined management strategy,and the parameters of the combined management strategy with the goal of the optimal improvement effect of the total system cost were collaboratively optimized.The results show that the market price of the tradable credit can be uniquely determined after the combined management strategy is implemented.The total number of vehicles in the system is reduced,the duration of the morning rush hour in both lanes is shortened,and the traffic congestion is improved.There are combined management strategy parameters that satisfy the specific relationship to optimize the total system cost improvement,and the market penetration of private and shared autonomous vehicles can be obtained when the system is optimal.The research can provide new ideas for future urban traffic management.
