Analytic Process to Develop a Local Truck Driving Cycle

Driving cycles have been used in Federal Test Procedures to establish fuel economy and emissions characteristics for automobiles. Reasonable driving cycles for trucks and buses have been more difficult to establish because of the great variety of uses which these vehicles experience. The truck cycle has been divided into three different use categories—the local cycle, the short haul cycle, and the highway cycle. Only recently, has actual field data been obtained, and this paper proposes a method of utilizing this data to develop a more realistic local cycle than those previously proposed.
