RES2024-02: Applying Induced Travel Study in Urban Areas in Tennessee
In Tennessee growing traffic congestion is quickly becoming more prominent. The most significant national-level freight corridors cross the state and are predicted to grow significantly in the future. Unprecedented growth worsened traffic conditions in western, central, and eastern Tennessee, especially severely in urban areas. To manage congestion on the freeways and major arterials, the Tennessee Department of Transportation (TDOT) commissioned the development of Congestion Action Plans for the four largest urban areas (Chattanooga, Knoxville, Memphis, and Nashville). However, it is not clear how much the same induced travel effect holds for the cities in Tennessee as current scholarship on the topic is lacking except a few studies that go back several decades (DeCorla-Souza, 2000; COMSIS, 1996) making this research on evidence-based estimates very timely. A key objective is to estimate the short-run local impacts of lane capacity expansions on vehicle miles travel (VMT), speed (measured in miles-per-hour), and traffic flow (i.e., the number of vehicles per hour that pass a particular location) for evidence-based analysis of induced travel in major metro areas in TN (Chattanooga, Knoxville, Memphis, and Nashville) utilizing consistent data sources and methods of analysis. using data from the publicly available Highway Performance Monitoring System (HPMS) inventory system.
