Shared ride-hailing services are discreetly emerging in cities all over the world, with the purpose of providing a transport service more flexible than the public bus and cheaper than the regular taxi. Hence, it is important to identify and include the relevant and key fa ctors of such a service to ensure its success. The aim of this study was to investigate the utility of a commu ting on-demand shared ride-hailing service and determine the design factors for an appropriate ser vice from the users’ perspective. During one week, a pilot of a shared ride-hailing service to commute f rom the city centre of Barcelona to the most western district of the city was conducted. Although the s ample used in this study was modest in scale, it enabled to draw preliminary conclusions. Users valued very positively the comfort provided but they would not pay more than the double of the price of the public transport. This indicates that despite having a high number of users, such a low price could c omplicate the profitability of the service unless it was partially subsidized.
