Abstract
Road users experience different transportation-related issues ranging from congestion, delay, and crashes, which are partially due to growing background traffic and traffic generated by new land use developments. With regard to congestion, metropolitan planning organizations (MPOs) pursue a variety of measures for mitigating congestion resulting as the product of new land use developments. These measures may include imposing impact fees or proportionate fair share to the developers amongst others. Literature review in the United States has revealed that, impact fees and proportionate fair shares are calculated solely to mitigate impacted intersection or link capacity but does not consider other safety and operational measures such as travel time. This paper introduces travel time mitigation fee model, which takes into consideration additional delay to the road users resulting from new trips added to the highway from new land use developments. The congestion pricing approach is used to determine the average and marginal effects of the travel time. With the known values of time, vehicle occupancy, and number of travel days per year, delay fee model in terms of cost per unit increase trip in land use development trip is estimated. An Illustrative example is used to demonstrate the use of the proposed delay fee model.
