How do adverse weather conditions affect demands on urban transport systems?

Abstract

Mode choice research in urban transportation constitutes a very important part of transportation planning in terms of studies such as decision-making on public transportation policies, mode-shifting and traffic calming practices, etc. Mode choice researches, which are usually made for an ordinary day within the scope of transportation masterplan studies, are also carried out for some special cases such as public holidays, adverse weather conditions, and the day of sports competitions, in order to shed light on the decisions that policy-makers and local governments will take in different scenarios. In this study, the changes in the daily user counters of the public transportation systems in Izmir, Turkey, according to the weather conditions were examined. The mode shifts and changes in demands were evaluated according to the adverse weather conditions, and the measures to be taken are discussed.
