Abstract
The purpose of this report is to compare vehicle operational characteristics of the EPA highway driving cycle with those of the General Motors Rural RT data (GM rural driving data filtered by road type). The computer program developed by GM to evaluate the rural GM CHASE Car data was also employed to analyze the highway schedule. Therefore, driving characteristics for both the GM Rural RT data and EPA HDDS were tabulated according to common criteria. Initially, the more easily calculable parameters such as average trip length, average trip duration, and average trip speed are contrasted for the EPA HDDS and GM Rural RT data. Conclusion: comparison between the EPA HDDS and GM data seems to suggest that both have very similar operational characteristics, most notably average trip speed. The primary discrepancies found are that the highway cycle has more stops/mile and the GM data includes substantial driving at speeds above 60 mph.
