The M@rsoin Scientific Interest Group (GIS) has undertaken to measure the different forms of carpooling, and to take into account all of these practices, even when they do not use a platform.
Its analysis is based on the results of a survey conducted in June 2016 on a sample of 2,000 French people aged 18 or older (a representative sample of the French population by age, gender, occupation and region of residence).
According to this survey, carpooling is more developed for long-distance trips, with a total of 52% of regular or occasional use, compared to 36% for home-to-work trips and 40% for daily trips.
"In the end, if we aggregate the three types of travel (long distance, home-work and daily travel), 62% of French people have already carpooled at least occasionally.
"These practices, while different, are nonetheless intertwined. Carpooling on one type of trip increases the probability of carpooling on another type of trip. Sixty-two percent of those who carpool do so on at least two trip types, and a quarter do so on all three trip types considered in the study. When only one type of trip is carpooled, it is most often long-distance trips.A relatively weak role for institutions and digital platforms
Another interesting result of this survey is that the practice is overwhelmingly based on interpersonal relationships for all three types of trips.The survey highlights "not only the dominant role of interpersonal relationships, on which a very large majority of carpooling practices are based (between 67% and 82% of respondents state that it is, most often, an arrangement with people they know), but also the very weak role of institutions.
While institutions seem to be better at organizing commuting trips than other types of trips, their role is still marginal with only 8% of commuters reporting that their carpooling is organized by an institution.The use of Internet sites also remains relatively low overall, according to this survey, "even if it is more important for long-distance carpooling, for which the matching between supplier and applicant is more complex; it is also more important when the practice is regular.
Only 25% of carpooling users have used a carpooling platform for at least one type of trip. On the other hand, 40% of regular carpooling users for long-distance trips have used it.
Motivations that vary according to the type of trip
The most frequently cited primary motivation for carpooling was to help each other (37% of respondents), followed closely by financial aspects (33% of respondents). Figure 1 shows the primary motivation for each carpooling combination.The main motivation for long-distance carpooling, on the other hand, is financial: 47% of those who only carpool long distance say that the motivation is to save money.
