Analysis of Opportunities for Truck Platooning from Telematics Data

NREL completed a geospatial & temporal analysis of telematics data to estimate the fraction of platoonable miles traveled by class 8 tractor trailers. The telematics data set consist of over 57,000 unique vehicles traveling over 210 million miles combined during a two week period in which the vehicles consumed 75% of their fuel in top gear. The data is at a one hour resolution resulting in 22% of miles being driven at an unknown speed. Multiple analysis methods to estimate platoonable miles are discussed. Results indicate that 60-75% of total miles driven at known speeds are at speeds amenable to platooning. Taking into account availability of a nearby partner vehicle going the same direction regional results ranged from 33% platoonable to 71% platoonable.

Potentials for Platooning in U.S. Highway Freight Transport

Abstract Smart technologies enabling connection among vehicles and between vehicles and infrastructure as well as vehicle automation to assist human operators are receiving significant attention as a means for improving road transportation systems by reducing fuel consumption – and related emissions – while also providing additional benefits through improving overall traffic safety and efficiency. For truck applications, which are currently responsible for nearly three-quarters of the total U.S. freight energy use and greenhouse gas (GHG) emissions, platooning has been identified as an early feature for connected and automated vehicles (CAVs) that could provide significant fuel savings and improved traffic safety and efficiency without radical design or technology changes compared to existing vehicles.
