In this paper, the dynamic optimal toll design problem is considered as a one leader-many followers hierarchical non-cooperative game. On a given network the road authority as the leader tolls some links in order to reach its objective, while travelers as followers minimize their perceived travel costs. So far toll has always been considered either as constant or as time-varying. Inspired by the San Diego's Interstate 15 congestion pricing project, in which heuristics with toll proportional to traffic flow are applied on a real two-link highway network, we consider toll as proportional to traffic flows in the network. On a three-link network we investigate various toll schemes and their influence on the outcome of the game for the road authority. We show that the use of alternative toll schemes may improve system performance remarkably.

In this paper we estimate technical efficiency in International Air Transport, by means of Stochastic Frontier Analysis (SFA) using a panel set of the world's twenty-four (24) largest network airlines, for the period 1991-2000. The results are compared to those from Data Envelopment Analysis (DEA), a popular approach for efficiency measurement in the literature. Findings suggest that airlines experience constant returns to scale, while technical efficiency ranges between 51% and 97% approximately. Furthermore, the level of technology experienced a slight increase, while the privatization of few of the airlines in the data set didn’t seem to affect their technical efficiency. Results from SFA and DEA do not vary significantly.

Incidents cause a large part of the delays in road networks. This is caused by a decrease of the capacity at the incident site. A detailed knowledge of the queue discharge rate can improve for instance the traffic prediction and thereby improve delay information or routing advice. Therefore, this study determines the queue discharge rate for many incident locations during an incident situation and these are compared with the queue discharge rate at the same location in normal conditions. Ninety incidents meet the requirements to apply the proposed methodology. It is found in case a driving lane is blocked, the queue discharge rate for each available lane is reduced by 50%. In case the driving lanes are open but there is a distraction of an incident at the emergency lane or on the roadway for the opposite direction, the queue discharge rate is reduced by 30%.

This paper investigates gender differences in the origin and terminal vertices of the time-space prism. Using the stochastic frontier method, separate models are constructed for females and males, based on data extracted from activity/travel diaries collected in The Netherlands. As activity patterns become more diverse, multiple peak distributions in arrival or departure times may be observed, to which the stochastic frontier method cannot be applied without violating its assumptions. By disentangling the multiple peak distributions, we demonstrate how this may be circumvented. The results indicate that the factors relating to the male and female prism vertices are not the same and are not in the same order of importance. The results are also discussed in relation to accessibility, further research directions and Dutch policies on gender equality.

This paper reports on a stated choice experiment examining the determinants of travelers' need and willingness to pay for advanced public transport information services. Specific attention is given to the role of making transfers in the decision to acquire specific types of information. Intercity train travelers are asked to choose among information services that varied in type of information provided by the services, precision of provided dynamic travel time estimates, whether or not the system can provide information unasked for and price. Respondents made these choices conditional on a specified transfer context, denoting whether or not transfers had to be made during the trip, and whether these were transfers to high or low frequency train services. Modeling results indicate that as hypothesized, transferring during the trip, especially towards low frequency connections, induces a larger need for travel information, a higher preference for services that can provide advice relative to other information and a higher willingness to pay for information in general. However, the choice for information services is highly price sensitive, which suggest a low overall willingness to pay.

Road pricing has a long and checkered history with many failed attempts interspersed by a small number of successes around the world. A question at the forefront of research and policy is whether the successes and failures hold useful lessons for designing and implementing roadpricing schemes in other countries and cities. Road Congestion Pricing in Europe (RCPE) provides a welcome and informative contribution to the debate.
