Exclusive Lanes for Trucks and Passengers Vehicles on Interstate Highways inVirginia: An Economic Evaluation

摘要

Increase in heavy truck traffic on Virginia's highways in recent years haveraised concerns about both safety and a capacity, particularly on the interstate system. Transportation agencies have developed a number of strategies for dealing with the impacts on safety and capacity of a truck population that has been increasing in volume and in the percentage of large tractor-trailers. One strategy that has been suggested is separate lanes for trucks and passenger vehicles. This study evaluated a computer program, Exclusive Vehicles Facilities (EVFS), developed by the Federal Highway Administration for determining the economic feasibility of separating trucks and other vehicles on freeway segments. A 50.7-km (331.5-mi) segment of I-81 in Virginia was selected to demonstrate the application of the program.
