Abstract

Introduction of autonomous and connected trucks (ACTs) is expected to result in drastic changes in operational characteristics of freight shipments, which may in turn have significant impacts on efficiency, safety, energy consumption, and infrastructure durability. One such important change is the formation of truck platoons. Truck platoons will become more feasible and practical with the intelligent technologies existing in ACTs that enable the connection among vehicles and between vehicles and infrastructure. Reducing congestion and braking/accelerating and improving fuel efficiency are some of reported and expected benefits of platooning. Yet such platooning operations may accelerate the damage accumulation within pavement structures because the lateral position of successive trucks within a lane is expected to be similar (i.e., channelized traffic) and the time between two consecutive axle loads (i.e., resting time) is expected to be reduced. Therefore, this study develops a platooning-control strategy for a fleet of ACTs such that the lateral position of trucks and spacing between them can be explicitly optimized to minimize damage to the pavement, thus significantly reducing maintenance and rehabilitation costs. In the paper, the efficiency of the proposed strategy was demonstrated through a case study.
