Recent nationwide debate concerning the success of high-occupancy vehicle (HOV) lanes to reduce congestion has been fueled by negative public sentiment that such lanes are not serving their purpose. Carpooling declined nationally by an average of 30 percent in the past two decades. Yet, on Texas freeway corridors with mature HOV lanes, recent research has shown an increase in carpooling of 100 percent or greater during the same period. Implementing an HOV lane in a corridor can provide a number of benefits. Some of these benefits include travel-time savings and trip-time reliability for eligible vehicles, increased person throughput, reduced fuel consumption, decreased vehicle emissions, reduced bus operating costs, and increased efficiency for the entire system. This document provides guidance related to implementation of HOV lanes in the Dallas area. It is based on the results of a three-year research project sponsored by the Texas Department of Transportation to evaluate effectiveness of operating HOV lanes in the Dallas District.
