Modeling travel behavior onboard of privately autonomous vehicle and shared autonomous vehicle
- 1 Department of Transport Technology and Economics Budapest University of Technology and Economics
The impact of travel time, travel cost, and multitasking availability on the selection of privately use AV (PAV) and shared AV (SAV) are examined. The main daily trip is only studied, where all trips are within urban areas. A stated preference (SP) survey which includes a discrete choice experiment, was designed and distributed in Budapest, Hungary to collect the preferences of people towards PAV and SAV. As a result, a sample size of 2056 observations was obtained from the survey. A discrete choice modeling approach was applied to the data using a conditional logit (CL) model, where the characteristics of the alternatives are considered. The analysis results show that the value of travel time (VOT) of SAV is lower than AV, and the probability of choosing a transport mode is increased when multitasking is available in a transport mode. Moreover, the impact of travel cost on transport mode choice is higher than the impact of travel time. In conclusion, people are more likely to select SAV over PAV when the multitasking availability is considered as one criterion in the transport mode selection.
