RES2021-01: Comprehensive Analysis on the Conversion of the Existing HOV Lanes into Hot Lanes in TN

RES2021-01

The objective of the proposed project is to assess required actions and implications of converting existing high occupancy vehicle (HOV) lanes in Tennessee into high occupancy toll (HOT) lanes. The research will focus on the technical and public policy issues and the likely impacts on the interstate corridors, system users (including commuters and truck drivers), land use patterns, existing transportation modes, and regional travel behaviors and patterns. The study is to answer the following questions: (1) Can the weaving behaviors of vehicles in HOV lanes be reduced regardless of whether the lane is operated as an HOV or HOT lane? (2) How will patterns in land use development impact O-D estimates and corridor operations? (3) Will the conversion of HOV lanes to HOT lanes: Decrease the travel time and improve the throughput for specific corridors? Lower fuel costs for Tennessee motorists? Efficiently reduce congestion? Lead to fewer emissions and improved air quality? Reduce stop-and-go traffic? (4) What are the public and road users’ perception and opinions on introducing HOT lanes in TN?
