Abstract:The upsurge in ride-hailing services and their rapidly growing demand have recently ignited considerable research interest. However, present research on ride-hailing is mainly focused on the demand for trips, while less attention is given to the supply enabling them, i.e., the drivers. To obtain a comprehensive understanding of ride-hailing demand, a good understanding of driver participation should be achieved. The present study aims to obtain a realistic representation of driver participation that will later be embedded in a multi-agent simulation. To date, ride-hailing research has been hampered by a lack of data, yet here we leverage a unique dataset of Lyft and Uber vehicle traces collected in San Francisco. Using a choice modeling approach, we model driver participation within four steps, estimating: (1) number of shifts on the working day, (2) shift duration, (3) shift start time, and (4) shift start location. Driver type (full-time, part-time, occasional) was found to be a strong determinant of driver participation. Full-time, but not occasional, drivers were found to work both more shifts and longer shifts. A higher number of shifts started in the downtown area (where population and employment are higher) and in higher income areas, while less shifts started in areas of high student density. Based on these modeling results, a driver fleet was generated for a typical weekday. This is one of the first studies to estimate ride-hailing driver behavior, offering insights that can potentially support transit agencies in effectively planning and regulating multi-modal transportation.
