“…Carsharing subscribers are mainly male and between the age of 35 and 45 years, with a higher education and income [4,5,22]. Referring to merely free floating carsharing services, which presents a new mobility service, more than half of the users are male and younger than 35 with a high share of full-time employment [5,23].…”

Purpose The majority of current e-carsharing users are middle-aged men with a high education and high income; they are most likely to have a full-time employment. Women are consistently underrepresented in previous studies and therefore this paper focusses on characterization of female early adopters. It builds a basis to identify current female early adopters and understand their preferences in e-carsharing in order to address women as target groups for e-carsharing. Methods A sample of 492 carsharing subscribers from Berlin is analysed according to socio-demographic backgrounds, mode choice, use and evaluation of (e-) carsharing services. Additionally, attitudinal indices and clusters based on mobility related attitudes are analysed to reveal significant differences between male and female users. Results Generally, the results confirm socio-demographic findings from previous literature about early adopters. Comparing females and males revealed differences in income, employment status and age. Female early adopters used battery electric vehicles (BEVs) more often than vehicles with an internal combustion engine and evaluate handling BEVs more positive. They show a higher bike affinity and lower affinities towards technology and innovation than male respondents. They combine public transportation and bicycling with the use of (e-) carsharing services as an additional part of urban mobility. Children do not seem to have an impact of the respective topics, although the findings suggest that services are not used with children. Conclusions The analysis of carsharing schemes needs to focus on specific requirements of each trip (e.g. transporting or accompanying children) in order to make sustainable mobility an option for others than one 'typical early adopter'.

Abstract. Rapid growth rates seem to indicate that recently introduced free-floating car sharing (FFCS) can mean a breakthrough for the car sharing idea. Like other vehicle sharing systems, FFCS systems face significant regional demand fluctuations. Thus, providers might have to reposition empty vehicles to not lose potential customers. However, this aspect has been hardly examined in research and practice. This study aims to investigate appropriate relocation strategies for this new type of car sharing systems regarding the case of car2go. For this purpose a survey based evaluation was conducted, new relocation strategies were developed, and a discrete-event simulation model for the evaluation with real time data from car2go was drafted. The results indicate that availability of cars is crucial for customer acceptance, but customers are open for smart relocation strategies. Furthermore, the developed simulation approach provides the basis for an in-depth analysis of various strategies with different objectives using a realistic demand forecast.

“…Only recently, research has extended its scope to the newest forms of car-sharing such as free-floating car-sharing and their environmental impact. Whilst early studies expected a significant reduction in car ownership and CO 2 emissions (Firnkorn and Müller, 2011) due to free-floating car-sharing, the actual impact seems to be more complex as non-car-owners reduce bike, walk and public transit trips, but start to use a (shared) car instead (Firnkorn, 2012). First reports from municipalities having introduced free-floating car-sharing are also ambivalent.…”

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 transportation users and (former) car-owners. However, given their highly flexible nature and different pricing structures, previous findings on user groups and environmental impact of station-based car-sharing may not be easily transferable. Therefore, this research uses survey data to directly compare user groups and usage patterns of a free-floating and station-based carsharing service both operating in the city of Basel. The findings suggest, that the schemes indeed attract different user groups and are also used differently. Moreover, it is shown, that car-sharing membership is governed by other factors than car-sharing activity. Given the observed structural differences, the environmental impact of free-floating car-sharing is yet to be determined.
