We estimate the marginal external congestion cost of motor-vehicle travel for Rome, Italy, using a methodology that … accounts for hypercongestion (a situation where congestion decreases a road’s throughput). We show that the external cost â … hypercongested for more than one hour per day. Hypercongestion accounts for about 40 percent of congestion-related welfare losses …

related to the introduction of congestion policies, focusing on tradeable driving permits and congestion tolls. We have the … congestion policies welfare-reducing. Second, drivers will oppose the policies even when they receive all permits for free, or … political majority to support both congestion policies. Third, in an infinite horizon setting, tradable permits are superior to …

Reducing electricity system congestion decreases ozone and PM2.5 concentrations in New England and New York and increases them … quantify the health impacts of changes in environmental pollution induced by a reduction in congestion and find overall health …

In classical traffic flow theory, there are two velocities associated with a given level of traffic flow. Following … demonstrates that a steady-state hypercongested equilibrium can be stable. Some other sensible models of traffic congestion …
