MOBILE SOURCE EMISSION IMPACTS OF HIGH OCCUPANCY VEHICLE FACILITIES

This paper appears in a compendium of conference papers and describes research to verify and validate two methods that estimate the potential mobile source emission reduction of high occupancy vehicle (HOV) facilities. Results obtained from these methods are not consistent with the implementation of HOV facilities; both models failed validation due to their inability to accurately predict observed changes in travel characteristics due to implementation of HOV facilities. Three recommendations stem from the research: 1) one method has potential for future use, however, it must be modified to account for HOV trips by trip purpose and include a more conservative speed change methodology; 2) traffic characteristic data are best for model validation due to the current state of technology; and 3) more research is needed to determine the validity of methods that assess the potential emission reduction of HOV facilities. The Clean Air Act Amendments of 1990 mandate the use of transportation control measures, such as HOV facilities, in non-attainment areas.
