Construction and road maintenance are ordinary activities frequently undertaken to maintain the well-being of road infrastructure. When these activities take place, they impact traffic flow and generate delays to the road users. Costs are imposed on the users on heavily traveled routes due to traffic slowdowns or even shutdowns. At rush-hour these direct and indirect costs come to a peak. Construction and road maintenance closures can take place at times when the negative impacts would be minimized. This study focused on the appropriate guidelines for lane occupancy charges that would eventually minimize the disutility of traffic lane closure. The project research team examined heavily traveled locations in the New Jersey region, with the cooperation of New Jersey Department of Transportation engineers. They examined traffic and construction patterns to be used in the analysis and developed general occupancy charge guidelines. Information regarding traffic flow with respect to time of day, season, annual average daily traffic, highway characteristics, etc., was reviewed. The project considered both economic and simulation analysis for examining the impact on user cost and construction operations due to different patterns of lane closure.
