Research by M. Fosgerau and Colleagues in Urban Economics Provides New Insights


  2012 APR 20 - (VerticalNews.com) -- According to the authors of recent research from Cachan, France, "We consider dynamic congestion in an urban setting where trip origins are spatially distributed. All travelers must pass through a downtown bottleneck in order to reach their destination in the CBD."

  "Each traveler chooses departure time to maximize general concave scheduling utility. We find that, at equilibrium, travelers sort according to their distance to the destination; the queue is always unimodal regardless of the spatial distribution of trip origins. We construct a welfare maximizing tolling regime, which eliminates congestion. All travelers located beyond a critical distance from the CBD gain from tolling, even when toll revenues are not redistributed, while nearby travelers lose," wrote M. Fosgerau and colleagues.

  The researchers concluded: "We discuss our results in the context of acceptability of tolling policies."

  Fosgerau and colleagues published their study in the Journal of Urban Economics (Congestion in a city with a central bottleneck. Journal of Urban Economics, 2012;71(3):269-277).
