Abstract: Truck-only lanes and tollways have been promoted as a way to combat road congestion, enhance safety and reduce pavement damage. This paper explores one aspect of truck lanes by considering whether there are advantages in separating cars and trucks. The benefits of vehicle separation are found to depend on several factors: the relative volumes of cars and trucks, the congestion delay and safety hazards that each type of vehicle imposes, values of travel time for cars and trucks, and lane capacity indivisibilities. The optimal assignment of vehicles to lanes can be supported using tolls that are differentiated by vehicle type and route. By contrast, lane access restrictions generally cannot support the optimum and may provide no benefit at all.
