Titel: Comparing Car-Sharing Schemes in Switzerland: User Groups and Usage Patterns
Kurzbeschreibung: Free-floating car-sharing schemes operate without fixed car-sharing stations, ahead reservations or return-trip requirements. Providing fast and convenient motorization, they attract both public transport users and (former) car-owners. Therefore, the environmental impact of these novel systems is hard to estimate. This research uses a difference in difference approach to estimate the impact of free-floating car-sharing on its members' travel behaviour. Data is collected using member surveys combined with a smartphone-based GPS-tracking solution. The results can be directly compared with both a station-based round-trip car-sharing service operating in the same city and a random control group. The findings suggest, that free-floating car-sharing has a similar socio-demographic customer potential as station-based round-trip car-sharing. However, free-floating car-sharing has more active members and is employed for a broader variety of uses. Moreover, the results suggest, that it reduces car-ownership on a level comparable to station-based round-trip car-sharing.2

Titel: Impacts of a new free-floating carsharing system traced with a Smartphone App
Kurzbeschreibung: Ubiquitous mobile devices such as smartphones allow real-time exchange of information. This enables new forms of social interactions and supports the idea of a shared economy. One of the best-known and most widespread applications in a shared economy is carsharing of which free-floating carsharing benefits the most from the new communication technologies. Since free floating carsharing is a new service, knowledge about its impacts is still very limited. Empirical studies in the few cities with the service have identified major user groups and their motivations to use free-floating carsharing. In addition, they analysed the dominant usage patterns as well as environmental implications (e.g. Schmöller et al., 2014; Kopp et al., 2013). Yet, these facets have been treated separately leaving possibly important links undetected. Moreover, it is still unclear how a growing diffusion of free-floating carsharing services affects overall travel behaviour (Seattle Department of Transportation, 2014). In this paper, we attempt a comprehensive investigation of the usage and impacts of free-floating carsharing based on a detailed analysis on the individual users. Given the sporadic nature of carsharing use, this goal implies surveying carsharing users for several days. However, traditional survey techniques would impose a large burden on the respondents and would therefore suffer from a low response rate and also from underreporting. Collecting the required data would be too expensive for the operator or the planner, regulator. A different approach is needed. The use of smartphones as observation tool promises a more reliable and more detailed observation of travel behaviour at reasonable cost while reducing the burden for participants. First studies (e.g. Pereira et al., 2013) have produced encouraging results. In this research, a new smartphone tracking app is used to acquire rich revealed preference data on the individual participants and their trips.2

Titel: Car-sharing in Switzerland - comparison of user groups
Kurzbeschreibung: A survey was conducted to study customer groups and usage patterns for a station-based and a free-floating car-sharing service in Basel. It was found, that the two car-sharing services serve different groups and are used in different ways. In particular, the free-floating car-sharing service attracts a broad variety of customers. Contrarily, the station-based car-sharing service is especially appealing to highly-educated and high-income people from non-car households. Also, station-based car-sharing is mainly used for purposes actually requiring a car, whereas most free-floating car-sharing rides could in principle also have been done using public transit. Therefore, station-based carsharing direcly enables and serves carless households, whilst free-floating car-sharing does so indirectly by providing efficient transportation on a trip-basis.2

Titel: Neutron production and thermal moderation at the PSI UCN source
Kurzbeschreibung: We report on gold foil activation measurements performed along a vertical channel along the tank of the ultracold neutron source at the Paul Scherrer Institute. The activities obtained at various distances from the spallation target are in very good agreement with MCNPX simulations which take into account the detailed description of the source as built.2
