Beyond Traditional Value-of-time: Passenger Behaviour for Multimodal Door-to-door Travels in the Age of Information Technologies

We look at previous research on various transport modes to identify how people currently behave when deciding to travel and choosing their transport modes and study the relevancy of considering other attributes than just price and time of travel.
Today, new services and products open a realm of possibilities to the imagination of individuals, leading to profound changes in the way we live and move. While transport has traditionally been viewed as a constraint in daily life, mobility now becomes a part of it.
Beyond traditional transport modes organized by operators, additional services provide travellers with means to organise, control and optimise their own door-to-door mobility and to turn their travels into a useful or even enjoyable time.
For these reasons, the current way of analysing passenger travel choices does not seem to reflect anymore the way people behave when they decide to travel and choose their transport modes.
For practicality reasons, current transport models usually consider individual transport modes with the attributes of monetary costs and time costs, using the value of time of travellers. This leads to the supremacy of speed in models of passenger behaviour and in the evaluation of transport infrastructure project: it is assumed that people will always favour the fastest transport mode, unless it is more expensive than others. Speed becomes the very first attribute of the utility of travel, while the cost of travel enters the budget constraint of the individual.
However, today people seem to consider other attributes than just price and time of travel. Moreover they usually string together several transport modes from origin to destination, and take into account the whole package when deciding about their trip
In this paper we look at previous research on various transport modes (or combination of transport modes) in order to identify how people currently behave when deciding to travel and choosing their transport modes. What attributes should be considered when analysing transport choices? For example, how do passengers value real-time information on traffic that, if used, enable them to improve the quality of their trips through anticipation and selection of the best solution for the endpoints of the trip? How do they value the use of phone or internet connections during their travel time? More generally, how would they like to use their travel time?
This enables us to identify some of the new attributes that should enter transport models and to think about data collection to go further into the identification of passenger behaviour, in order to think about future mobility with better tools of analysis.
