Truck and Auto Performance Measurement Using Probe-Based Speed Data: Case Study of I-95 Corridor in Maryland
This paper calculates the mobility performance measures based on the National Performance Management Research Data Set (NPMRDS) on the I-95 corridor in Maryland. Separate performance measures are computed for each of the three data sets within NPMRDS: auto, truck, and all vehicles. Cross classification is done to compare how much of the time performance measures calculated for each data set match. Travel time index (TTI) and planning time index (PTI) are the performance measures used in this study as an indicator of congestion and reliability respectively. Based on the cross classification, the congestion performance measure matched between all three data sets the majority of the time, while the reliability performance measure rarely matched.
