Marginal congestion costs in the case of multi-class traffic: A macroscopic assessment for the Paris Region

Résumé

Although road congestion caused by freight activities is often pointed-out by researchers and public deciders as a major issue, few studies model time losses at a macroscopic-regional level within a 'multi-class traffic' framework. This research proposes such empirical assessment for the Paris region, using a simple method based on individuals' trip durations. We combine information on passengers and commercial transport (to describe road demand) with a GIS describing the stock of infrastructures (road supply) on that territory. According to econometric results, the travel times react differently to the flow of similar and dissimilar vehicles: Cars and vans are more impacted than trucks by the volume of 'small' vehicles, whereas 'large' vehicles are more affected than cars and vans by the presence of other large vehicles. Our methodology thus highlights varying and reciprocal congestion impacts, which is not common in the literature. We then propose various marginal congestion costs, for various origin-destination pairs, various time periods and various types of vehicles. In particular, we decompose external losses incurred to each category of vehicles by each category of vehicles. These results constitute valuable materials for future appraisals of transport policies in the Paris region.
