International audienceWe model trip-timing decisions of rail transit users who trade off crowding costs and disutility from traveling early or late. With no fare or a uniform fare, ridership is too concentrated on timely trains. Marginal-cost-pricing calls for time-dependent fares that smooth train loads and generate more revenue than an optimal uniform fare. The welfare gains from time-dependent fares are unlikely to increase as ridership grows. However, imposing time-dependent fares raises the benefits of expanding capacity by either adding trains or increasing train capacity. We illustrate these results by calibrating the model to the Paris RER A transit system

Terms of use: Documents in AbstractCrowding on public transport (PT) is a major issue for commuters around the world. Nevertheless, economists have rarely investigated the causes of crowding discomfort. Furthermore, most evidence on the costs of PT crowding is based on contingent valuation studies. First, this paper assesses discomfort with PT crowding over dierent density levels, trip durations and across dierent individuals using a dierent methodology. Based on a survey of 1,000 Paris PT users, the negative, linear relationship of in-vehicle density on reported travel satisfaction is remarkably similar to previous studies investigating PT crowding costs and stable across most individual characteristics. Contrary to the identifying assumption of most contingent valuation studies, we nd little increase in crowding costs over travel time, in line with an additive specication of the generalized PT cost function. Second, we investigate the causes of this discomfort eect. We identify three key drivers: (a) dissatisfaction with standing and not being seated; (b) less opportunities to make use of the time during the journey; (c) the physical closeness of other travellers per se.

Long-distance carpooling is an emerging mode in France and Europe, but little is known about monetary values of this mode attributes in transport economics. We conducted a discrete choice experiment to identify and measure the values of attributes of long-distance transport modes for a trip as a driver and as a passenger, with a special focus on carpooling. Around 1.700 French individuals have been surveyed.We use discrete mixed logit models to estimate the probability of mode choice. We find that the value of travel time for a driver who carpools is on average 13% higher than the value of travel time when driving alone in his/her car. The average value of travel time for a carpool trip as passenger is around 26 euros per hour, 60% higher than for a train trip and 20% higher than for a bus trip. Moreover, our study confirms a strong preference for driving solo over taking carpoolers in one's car. We also show that individuals traveling as carpool passenger incur a "discomfort" cost of on average 4.5 euros per extra passenger in the same vehicle. Finally, we identify robust socio-economic effects affecting the probability of carpooling, especially gender effects. When they drive a car, females are less likely to carpool than male, but they prefer to carpool two passengers over only one passenger.
