Abstract:

Carshare systems are seen as an appropriate solution for sustainable development in the future. To promote carsharing it is imperative to make it cost effective, which includes reduction in costs associated to crashes and insurance. To achieve this goal, it is important to characterize carshare users involved in crashes and understand factors that can explain at-fault and not-at fault drivers. This study utilizes data from GoGet carshare users in Sydney, Australia. Based on this study it was found that driving experience, higher insurance excess, needing car on weekends, owning a car reduced the likelihood of being in crash and being at fault. Further, the likelihood of not being at-fault reduced with higher insurance excess, not having previous instance of traffic offences, preference for luxurious cars and living near a dedicated parking. Marginal reduction in the propensity of being not-at-fault was also observed due to having a driver’s license from a country having a left hand drive, similar to that in Australia. The analysis of not-at-fault drivers also provides insights for quasi-induced exposure methods, suggesting that when applying quasi-induced exposure methods it is critical to control for insurance type, previous instance of traffic offences, vehicle type and what type of license the individual has. Finally, based on this study it is recommended that having higher insurance excess on risky drivers and also providing some incentives based on training and experience (based on kilometres driven), possibly on insurance excess could improve safety and reduce costs associated to crashes for carshare systems.
