Disruptions in the road transport system can have severe consequences for accessibility and transport costs. These impacts vary depending on in which regions they occur (regional importance), and users may be affected differently depending on where they travel (regional exposure). Some...

The COVID-19 pandemic has changed travel behaviour and reduced the use of public transport throughout the world, but the reduction has not been uniform. In this study we analyse the propensity to stop traveling by public transport during COVID-19 for the holders of 1.8 million smart cards in...

This paper establishes mild probability-theoretical conditions under which observations of space-averaged speed and occupancy in some area concentrate with low scatter around a well-defined curve. These conditions are validated against empirical data from Stockholm and Geneva. No equilibrating...

The paper analyses the impacts of COVID-19 on daily public transport ridership in Sweden during spring 2020, in particular the three most populated regions Stockholm, Västra Götaland and Skåne. The analysis is based on ticket validations, sales and passenger counts data. Public transport...

In this paper we introduce an activity-based modeling approach for evaluating the traveler costs of transport network disruptions. The model handles several important aspects of such events: increases in travel time may be very long in relation to the normal day-to-day fluctuations; the impact...
