Time-varying Tolls in a Dynamic Model of Road Traffic Congestion with Elastic Demand
نویسنده
چکیده
In this paper, a dynamic model of road traffic congestion is presented, with an elastic overall demand for morning peak road usage, and with the congestion technology used being ‘flow congestion’. It is demonstrated that in such a case, the optimal time-varying toll should include a ‘flat’, time-invariant component when road users share the same desired arrival time. This has important consequences for the design of optimal toll schemes in reality, because it implies that optimal tolls cannot be set if the regulator has no information on the road users’ desired arrival times.

Literature Review of Traffic Assignment: Static and Dynamic
Rapid urban growth is resulting into increase in travel demand and private vehicle ownership in urban areas. In the present scenario the existing infrastructure has failed to match the demand that leads to traffic congestion, vehicular pollution and accidents. With traffic congestion augmentation on the road, delay of commuters has increased and reliability of road network has decreased. Four s...
متن کاملPareto Improvements from Lexus Lanes
This paper shows that a judiciously designed toll applied to a portion of the lanes of a highway can be a Pareto improvement even before the revenue is spent. I achieve this new result by extending a standard dynamic congestion model to reflect an important additional traffic externality which transportation engineers have recently identified: additional traffic does not simply increase travel ...

Congestion pricing is one of the major travel demand management policies to reduce traffic volumes in metropolitans. One of the main factors for effective implementation of this policy is to analyze users' response to different toll rates. In this paper, the willingness of users to pay for using their personal cars is evaluated. The stated preference method was applied for data gathering. Sever...

Urban road networks in many countries are severely congested, resulting in increased travel times, increased number of stops, unexpected delays, greater travel cos...
متن کاملMinimal Revenue Tolls: Price Stability for Networks With BPR Cost Function
Marginal-Cost (MC) tolls are known to produce economic efficiency of network flows. Yet, MC pricing has not been widely adopted, because of various perceived unpopular aspects, such as complexity, collection costs, and inequities. Minimal Revenue (MinRev) pricing has been suggested as a means to achieve most of the economic improvements of MC pricing with fewer unpopular aspects. One claimed im...
