Abstract:

To alleviate the truck barrier effect in diverging areas under a connected and automated environment, a lane-changing model that conforms to diversion characteristics was constructed. The effects of the truck proportion, the arriving flow rate of going-straight vehicles, the arriving flow rate of departing vehicles, the time headway, and the platoon length on the truck barrier effect were analyzed. A truck platoon controlling strategy(TPCS)was proposed and evaluated by integrating a lane change control strategy and platoon length limit strategy. The results show that different combinations of the truck proportion, the arriving flow rate of going-straight vehicles, and the arriving flow rate of departing vehicles are the macroscopic conditions for the formation of truck barriers. From the microscopic aspect, five or more trucks traveling in a platoon with a time headway no more than 2 s will cause the truck barrier effect. In addition, compared to the platoon and non-platoon statuses, TPCS can improve the off-ramp flow by up to 60% and 43%, respectively. Therefore, when the conditions for the formation of the truck barrier are met, traffic managers can implement TPCS to alleviate the truck barrier effect.
