| Abstract | The purpose of this study was to identify sources of data for MOBILE 6 and set procedures to prepare the data in the format required for use in MOBILE 6. The Environmental Protection Agency (EPA) has provided a comprehensive set of documents describing proper use of MOBILE 6 and has also provided a full set of default values to assist in operation of the model. However, the EPA warns that local data should be used wherever possible, and efforts were made in this study to develop procedures that allow local data to be gathered for use in MOBILE 6. A proof-of-concept study was conducted on the use of Global Positioning System (GPS) instruments to estimate vehicle miles traveled (VMT) and soak times. From data of GPS-equipped vehicles in Lexington, Kentucky, gathering information on VMT and soak times in this manner appears to be feasible, and the results showed that local data is sometimes considerably different from that portrayed in MOBILE 6 default tables. Another method of local data collection tested in this study was a method used to estimate VMT from Highway Performance Monitoring System (HPMS) data without using volume groups. Volume groups are difficult to assign to links where no traffic count data exist. The method produces less accurate results than the current method (root mean square error of 1643 vehicles per day overall, versus 543 in the conventional method), but once established, it is easier to apply. |
