The principal subject of the report is driving behavior, including acceleration and trip start patterns. After reviewing existing research on driving behavior, EPA determined that new surveys were needed to assess current driving in U.S. urban nonattainment regions. A parallel study of current technology vehicle emissions under the full range of driving conditions is also in progress. Results from these efforts will be combined in determining the need for test procedure revisions. The preliminary technical report discusses how the driving surveys were conducted, presents analyses of the results, and compares the data to the existing FTP. Quantitative assessments of the emission impacts are still in progress and are not discussed in the report.
