متن کاملEstimating Urban Road Congestion Costs
Economists wishing to analyse road congestion and road pricing have usually relied on linkbased speed-flow relationships. These may provide a poor description of urban congestion, which mainly arises from delays at intersections. Using the simulation model SATURN, we investigate the second-best proportional traffic reduction and find that linear speed-flow relations describe network flows quite...
