ITEA Conference 2023 in Santander
The annual conference of the International Transport Economics Association (ITEA) was held at the University of Cantabria in Santander, Spain, from June 14-16, 2023. Participants of the conference are scientists and specialists in the field of transport economics. The Institute of Transport Economics of the University was represented by seven scientists. Tim Podleschny, Sebastian Specht and Dr. Jan Wessel presented their research work and received valuable input for future research in the exciting discussions.
A highlight of the conference was the award ceremony for the best papers, where Dr. Jan Wessel from the Institute of Transportation Science at WWU Münster was awarded the "Richard J. Arnott Best Paper by a Junior Researcher Prize". His research paper, titled "Space Wars - Finding an Economically Efficient Allocation of Street Space Across Different Transport Modes," examines the economically efficient allocation of street space. Through a theoretical model of transportation mode choice and extensive simulations for the cities of Berlin and New York City, the study shows that reallocating street space from cars and parking in favor of buses and especially bicycles can increase the economic efficiency of the transportation system. The paper thus makes an important contribution to the current debate on the distribution of road space.
Gössling et al. (2023) claim to calculate the welfare effect of a speed limit of 130 km/h in Germany. Since they do not consider tax revenues from gasoline and diesel, they overestimate the welfare gain by about 378 million euros. A speed limit increases travel times. Gössling et al. (2023) calculate travel time increases using a simplified approach that underestimates costs by an order of magnitude equal to their full (tax-adjusted) welfare effect. A speed limit induces some traffic to switch to another mode or not to travel at all. The reduced costs of driving less are crucial to their calculation, but the losses in consumer surplus associated with reduced traffic are ignored. Gössling et al. (2023) do not calculate a value associated with the welfare changes of a 130 km/h speed limit on highways for Germany.
