Abstract
Many U.S. metropolitan areas are expecting significant growth in the amount of truck travel on their road networks. For those areas, such as Atlanta, Georgia, where the region experiences not only substantial truck movements internal to the region but also large numbers of through truck trips, this growth presents a significant challenge. A proof-of-concept analysis was undertaken in Atlanta to examine the likely impacts of various truck-only toll (TOT) lane strategies for the regional freeway network. Three strategies are examined: building new lanes along major truck corridors, allowing trucks to use existing high-occupancy vehicle (HOV) lanes inside the central area, and turning all proposed HOV lanes in the region into TOT lanes. The analysis of these strategies is presented, and the conclusion is that turning proposed HOV lanes into TOT lanes provides the greatest transportation benefit to the region.
