Description

Oregon is one of the few states that currently charge a commercial truck weight-mile tax (WMT). This research serves to evaluate ancillary applications for a system developed by the Oregon Department of Transportation (ODOT) to simplify WMT collection. The data collection system developed by ODOT – Truck Road Use Electronics (TRUE) - includes a smart phone application with a Global Positioning System (GPS) device and microprocessor. The TRUE data has enormous advantages over commercial truck GPS data used in previous research due to its level of disaggregation and its potential to differentiate between vehicle and commodity types. This research evaluates the accuracy of the TRUE data and demonstrates the results of its application to develop trip generation rates for a variety of truck types and land use categories. This research also confirms the value of the TRUE data to enhance existing ODOT transportation planning models and performance measures. Further, the potential use of the data for emission estimates is evaluated. A sensitivity analysis using the U.S. Environmental Protection Agency's (EPA) Motor Vehicle Emission Simulator 2010b (MOVES2010b) is performed in order to the understand the level of error that might be encountered in emission estimates when such detailed data is not available.
