Title: The Influence of Parking Regime on Intersection Capacity
Abstract: The modern concept of parking management, which refers to sustainable transport, is based on parking demand management. The most popular parking demand management policy is restricted parking regime. The introduction of parking charge and/or time limitation disables or discourages long-term parking, allowing realization of greater number of short-term parking. In this manner, by increasing the turnover on parking spaces, the parking demand and supply will eventually be balanced. However, while contributing to problem solving in this subsystem, the parking regime can adversely affect operation of other urban transport subsystems. Particularly strong impact this policy can have on dynamic traffic, precisely due to parking turnover increase. The increase in turnover, increases the traffic volumes on the one hand, and on another interferes with traffic flows reducing streets and intersections capacities. This paper examines the impact of parking regime (price and time limit) on the capacity of a signalised intersection. The analysis is based on the Highway Capacity Manual procedure for the calculation of intersection capacity. In this procedure, the capacity is a function of number of parking manoeuvres per hour within 250 ft upstream from the stop line. To forecast the influence of parking regime introduction/change on parking demand (and further on number of parking manoeuvres), good knowledge of parking users’ behaviour is required. User response to parking regime change is predicted on the basis of stated and revealed preference data and logit model. The developed methodology was tested in the inner central area of Belgrade, the capital of Serbia. The results show that parking regime has a strong influence on parking demand and hence on capacities of intersections within the area. In the present example, depending on chosen parking price and time limitation, the capacity may vary up to 27%. Due to the magnitude of the impact, it should be considered when defining the parking policy. Otherwise, the parking regime could jeopardise dynamic traffic’s normal operation. This, once again, emphasizes the importance of a comprehensive and integrated transport management, which is one of the main principles of sustainability.
