Carsharing Papers at the 2019 Transportation Research Board Meeting

Carsharing has come a long way since the 1990s.  This year there don't appear to be any presentations about carsharing, although a number of papers about one-way, round trip were accepted for publication. (see the end for how to read the full papers.)  

Several of the papers deal with providing incentives for carsharing users to achieve various goals, for example relocation, increase utilization.  Here are several that look interesting and a section of the abstract that caught my eye.  

Free-Floating Carsharing Users Willingness to Pay/Accept for Logistics Management Mechanisms

...The objective of this study is to establish FFCS customers’ preferences for each of four incentivisation mechanisms: 1) vehicle delivery, 2) paid relocation, and 3-4) incentivisation for alternate vehicle pick-up and drop-off locations. Survey data from FFCS users in Vancouver and Washington D.C. are employed to quantify willingness-to-pay/accept (WTP/WTA) for these mechanisms. We find that a majority of respondents report positive attitudes toward each of the four incentivisation mechanisms. Regression analysis shows that user experiences using FFCS are generally stronger predictors of WTP/WTA than socio-demographic features, with (intuitively) the frequency of FFCS unavailability the strongest predictor.

...The reward policy and the ranking method were tested in real operating environment of an electric vehicle sharing system in two districts of Shanghai. The result suggests that the reward policy with ranking method could shorten the vehicle idle time and increase the number of transactions per vehicle and per station, and also resulted in increments on profits.

Car Sharing: Impact on Mobility and Travel Choices and the Role of Life Events and Attitudes

...Car sharers were classified into five categories: car dependents, car avoiders, second car avoiders, car aspirers and car sellers. Key findings suggest that car sharing motives and impacts vary greatly for all categories. Car aspirers and car sellers report the greatest changes in mobility choices (car ownership) and travel choices (use of a car, public transport and active modes).

Here's the poster session:

Operational Considerations for Shared Mobility
Monday 8:00 AM- 9:45 AM 
Carol Schweiger, Schweiger Consulting LLC, presiding

...Shared mobility, particularly sharing rides, cars, bikes and scooters, is having a transformative effect on cities. Understanding what operational considerations affect the implementation of shared mobility services is critical to their success. This poster session explores several factors for consideration in the implementation of shared mobility in the transportation ecosystem.

All the sessions involving carsharing and shared mobility are listed ere:
