An Origin-Destination Based Parking Pricing Policy for Improving Equity in Urban Transportation

In this paper we propose to optimize parking pricing fares in urban areas with the aim to improve transportation equity; the optimization approach is applied to an origin-destination parking pricing policy that can differentiate the tariffs for each origin-destination pair, considering the difference in accessibility, in particular with public transport services. An optimization model is implemented, and a solution algorithm is proposed. Model and algorithm are tested on the case study of Naples (Italy), where the quality of transit services is very different between zones and OD pairs; therefore, differentiating parking fares as a function of origin and destination of the trip may be very useful for rebalancing accessibilities among zones, aiming to improve transportation equity.
