Travel time as quality time: parental attitudes to long distance travel with young children

Quality of Real-time Travel Time Information

travel time ∗

In this paper we use a model-based traffic control approach to determine dynamic speed limits with the aim of reducing fuel consumption and emissions, while still guaranteeing small travel times. The approach we propose is based on model predictive control (MPC). MPC is a modelbased control design method that combines prediction and on-line optimization of a performance criterion over a given t...

The Attitudes of Bus Users to Travel Time Variability

The Institute for Transport Studies at the University of Leeds is carrying out research about the reliability benefits from improved bus infrastructure. The study includes both demand and supply modelling, and it is hoped that the final stage of the project will include an economic analysis of the effects on reliability of different bus infrastructure improvement scenarios. Of the various measu...

Time Travel and Time Machines

This paper is an enquiry into the logical, metaphysical, and physical possibility of time travel understood in the sense of the existence of closed worldlines that can be traced out by physical objects. We argue that none of the purported paradoxes rule out time travel either on grounds of logic or metaphysics. More relevantly, modern spacetime theories such as general relativity seem to permit...

Music Cognition as Mental Time Travel

As we experience a temporal flux of events our expectations of future events change. Such expectations seem to be central to our perception of affect in music, but we have little understanding of how expectations change as recent information is integrated. When music establishes a pitch centre (tonality), we rapidly learn to anticipate its continuation. What happens when anticipations are chall...
