Since 2008 most older people in England have benefited from unlimited area-wide free travel by bus after the morning peak period. The official policy rhetoric supporting implementation of the measure drew significantly on the need to reduce social exclusion amongst older people. However, despite...

Waiting time uncertainty is one of the main determinants of public transport reliability and overall level-of-service. The dissemination of real-time information concerning vehicle arrivals is often considered an important measure to reduce unreliability. Moreover, the prediction of downstream...

This paper presents a transit simulation model designed to support evaluation of operations, planning and control, especially in the context of Advanced Public Transportation Systems (APTS). Examples of potential applications include frequency determination, evaluation of real-time control...

Transit systems exercise complex dynamics and evolve through the interaction of various agents. The analysis of transit performance requires emulating the dynamic loading of travellers and their interaction with the underlying transit system. Multi-agent simulations aim to mimic the emergence of...

Transit operations involve several inherent sources of uncertainty including dispatching time from the origin terminal, travel time between stops and dwell time at stops. Bus holding control strategies are among the prominent methods applied by transit operators in order to improve transit...

Denna rapport analyserar Trafikverkets, Transportstyrelsens, Konkurrensverkets och Konsumentverkets aktiviteter med järnvägs- och kollektivtrafikmarknaderna under januari till augusti 2012. Vi finner inga indikationer på att företag av Trafikverket förfördelats i tilldelningen av...

Denna rapport analyserar Trafikverkets, Transportstyrelsens, Konkurrensverkets och Konsumentverkets aktiviteter med järnvägs- och kollektivtrafikmarknaderna under 2011. Vi finner inga indikationer på att företag av Trafikverket förfördelats i tilldelningen av järnvägskapacitet. Däremot...

This study uses a stated choice experiment and drawings of four different type-environments to assess how various security-promoting factors in the built physical environment influence valuation of walking time when accessing public transport. Valuations that can be applied for evaluating...
