The paper aims to shed light on the determinants of choice for new forms of mobility or new modes of transport. More precisely, we focus on transport mode choice between coach and carpooling for long-distance trips in France. To do so, we perform a discrete choice experiment survey in which attributes reflecting elements of comfort and flexibility are introduced in addition to the conventional price and time attributes. The survey conducted among a small number of individuals who had already experienced coach and/or carpooling made it possible to collect 405 observations of choice. These data make it possible to infer values of time for the users of the modes by estimating econometric models. These values of time are significantly different since the carpoolers’ value of time appears at least twice as much as that of the coach users. Thus, at the sample average point, an individual’s willingness to pay to save one hour on travel time is €4.27 per hour for coach users compared to €10.53 per hour for carpool users or €6.23 per hour compared to €15.28 per hour respectively depending on the functional form chosen for the conditional indirect utility.
