Transportation sharing (e.g., car-sharing, freight-sharing, car-pooling, ridesharing) has received a lot of interest over the years. Despite the continued growth in transportation sharing, its potential in rural areas has not been fully explored. This paper provides a state-of-the-art review of the literature on sharing and transportation, particularly in rural areas. Based on findings from the literature, technological advancements, economic prospects, convenience, perceived environmental protection, the possibility to socialise, and avoidance of car ownership are some factors that have facilitated the growth of transportation sharing. Potential barriers to transportation-sharing in rural areas include poor regulation, poor network coverage and low, inconsistent demand due to few sprawled-out rural residents. Sharing in transportation has a great potential to provide sustainable solutions to transportation challenges in rural areas, as residents and visitors to these places overwhelmingly depend on car travel. Accordingly, transportation sharing could potentially reduce congestion, especially if car travel is combined with other modes (e.g., autonomous vehicles).
