Abstract

With the introduction of connected and autonomous trucks (CATs), truck platooning is expected to be more feasible and prevalent. The reported benefits of the truck platooning include regularizing traffic, reducing congestion, increasing highway safety, and decreasing fuel consumption and emission. Truck platooning may, however, decrease pavement longevity because it would cause channelized load application and hinder the healing properties of asphalt concrete. This study proposes a centralized control strategy that converts the pavement-related challenges of truck platooning into opportunities. This strategy leverages the auto-pilot technologies in CATs by optimizing the lateral position of each platoon or group of platoons. The efficiency of the proposed control strategy was demonstrated in a case study. Results showed that pavement life-cycle costs could be reduced up to 50% by controlling the lateral position of the platoons for each day.
