A result of EPA's heavy-duty cycle development project has been the computer-generation of some 35 candidate chassis cycles by the contractor, Olson Labs. This collection of cycles, synthesized from actual urban driving data, has been narrowed down by EPA to four cycles representing truck operation under both freeway and non-freeway conditions in Los Angeles and New York. In an effort to choose a cycle for each category which best represented the actual data, EPA scored the candidates according to their summary statistics, provided by Olson with each cycle.
