The gradually accelerating pace at which tolls are being implemented or actively considered around the world suggests that road pricing is an idea whose time may finally have come. Nevertheless, various design considerations must be addressed and public acceptability hurdles overcome if road...

New developments in transportation systems and the increasing complexities of urban living are creating challenges and opportunities to comprehensively address transportation problems. The key to exploiting new opportunities lies in understanding how travelers would respond to changes in the...

We study route choice behavior when travel time is uncertain. In this case, users choice depends both on expected travel time and travel time variability. We collected survey data in the Paris area and analyzed them using a method based on the ordered probit. This leads to an ordinal as well as...

This article contains an economic analysis of regulatory parking policies as a substitute to road pricing. The scope for such policies is discussed, after which a simple diagrammatic analysis is presented, focusing on the differences between the use of parking fees and physical restrictions on...

This paper contains a comment on an article by Professor Lave, recently published in this journal (Transpn Res. 28A, 83-91, 1994). Lave's approach towards analyzing the political feasibility of road pricing is challenged on several grounds. In a simple setting, where individual road users are...

The article contains a welfare economic analysis of road transport's external effects. First, we discuss the definition of external effects. Applying this definition, it is concluded that road transport activities give rise to a wide range of external costs. However, there are no external...

Private toll roads are now seriously considered as an alternative to public (free-access) road infrastructure. Nevertheless, complete private provision without governmental control is only rarely considered. A main consideration against private roads would be that operators would be primarily...

This paper models strategic interactions between a road supplier, a provider of traffic information, and road users, with stochastic travel times. Using a game-theoretical analysis of suppliers’ pricing strategies, we assess the social welfare effects of traffic information under various...

Advanced traveller information systems (ATIS) are likely to exhibit significant economies of scale in production and operation. Private provision would therefore typically occur under considerable market power. An important policy question is whether the resulting distortions would aggravate or...

A dynamic 'car-following' extension of the conventional economic model of traffic congestion is presented, which predicts the average cost function for trips in stationary states to be significantly different from the conventional average cost function derived from the speed-flow function. When...
