• Comparison of Two Dynamic Transportation Models: Case of Stockholm Congestion Charging
  Abstract: This paper reviews the transportation models used for predicting impacts of congestion charging in European cities and carries out in-depth comparison of two such models, METROPOLIS and SILVESTER. Both are mesoscopic dynamic models involving modal split and departure time choice calibrated for the Stockholm baseline situation without charges and applied for modeling effects of congestion charging. The results obtained from the two models are mutually compared and validated against actual outcome of the Stockholm congestion charging scheme. Both models provide significant improvement in realism over static models. However results of cost benefit analysis differ substantially.

• Evaluation of Impacts of Urban Road Pricing on Social and Spatial Inequalities
  Abstract: In the context of “sustainable” urban development, this paper evaluates the impact of setting up traffic toll zones, cordon pricing, on the evolution of inequalities based on a study of the conurbation of Lyon. It simulates a new charging policy implemented by imposing an urban road pricing to analyse its impacts on the evolution of inequalities with respect to the current situation used as reference. Four different types of indicator are used to achieve this. Besides “specific” indicators of inequalities such as those of Gini, Theil and Atkinson, the gravity-based measurement of accessibility is also considered to enlighten public decision-makers on the evolution of inequalities. In agreement with the literature, our results show that the different indicators of inequality produce highly contrasted and sometimes contradictory results on both the scale of the zone and that the city. Furthermore, although an improvement of accessibility was observed, notably for the central zones, it is the first ring (adjacent to the toll zone) that will be affected most negatively by the toll. This is confirmed by the three indicators. Lastly, the indicators of Theil and Atkinson alone show that introducing a toll can lead to reducing inequalities for the zones furthest away.

• Pareto-Improving Hybrid Policy for Transportation Networks
  Abstract: This paper investigates an innovative Pareto-improving hybrid policy that combines two policy instruments, i.e., congestion pricing and road space rationing, and takes advantage of the synergistic effects between those instruments. Mathematical formulations for developing Pareto-improving pure road space rationing schemes and hybrid policies are presented. Numerical examples demonstrate that the proposed hybrid policy offers greater flexibility and is more prominent in leading to Pareto improvement than both pure congestion pricing and road space rationing schemes.

• Demand Shifts and Observed Effects on Traffic Operation as a Result of Congestion Pricing Implementation on San Francisco Bay Bridge
  Abstract: The San Francisco Bay Bridge is one of heaviest travelled bridge in California and in the United States. A congestion pricing scheme was implemented on July 1st 2010. This paper describes the work that was conducted to evaluate the effects of such new toll policy on traffic operation. The study is based on traffic data that are acquired from vehicle detection stations located upstream of the toll plaza over a six-month period in 2010 and corresponding periods in 2009. With data aggregated into hourly and daily intervals, traffic attributes were extracted to compare performances before and after the introduction of the congestion pricing scheme. The findings indicated that the toll pricing policy led to a shift in travel demand and resulted in statistically significant effects on travel operation. In a relatively short term period, from June just before and July just after the toll changes, the morning peak hours’ average speed increased, the vehicle flow rate was lower, and travel time delay was reduced.
