Research on Commuting Travel Mode Choice of Car Owners Considering Return Trip Containing Activities

Abstract

Taking car owners as research objects, the present study investigates the choice of travel mode from the perspective of the travel chain. This study mainly focused on how car owners make travel mode choices during return trips containing activities. The research methods were based on two different decision criteria, namely, the expected utility theory and prospect theory. In the present study, the investigators considered that influence factors for decision-making were uncertainty of travel time and uncertainty of parking. Taking arrival time as the variable, two travel mode models based on these two theories were established. An example of the application of these two models was given to determine whether the return trip containing activities would make the car owners give up driving on the way to work, and under what conditions would they give up driving and switch to public transport. The results indicate that when the return trip contains activities and there are time constraints in these activities, car owners may give up driving to work in their departure trip. The uncertainties of arriving and parking are the main factors that make car owners give up driving. The demarcation points from car to public transport based on these two theories are very close, which indicates the consistency of the expected utility theory and prospect theory. It turns out the importance of the punctuality of public transport to attract the passenger flow, thereby reducing car travel and realizing low-carbon transportation.

“…Fourth, in most cities in China, morning rush hours are often centered in the period of 7:00-9:00 a.m. [45]. Thus, the experimental data in this study was not in rush hours.…”

Lane Choice Behavior at Toll Plaza Under Mixed Traffic Conditions Using TODIM Method: A Case Study

“…They found that traffic characteristics significantly affect lane changes (obtained highest weightage among all criteria). Sun et al [ 49 ] used the prospect theory for travel choice for the car drivers in the return trip. Li et al [ 6 ] applied the MCDM method for the lane change model.…”

Comparative mode choice analysis of university staff commuting travel preferences

“…According to De Vos et al (2016), the utility theories focus on the weight of those attributes which support mode choice decision. In addition, the parameters of a suitable utility function need to be defined (Sun et al, 2018). In most cases, modern informaticsbased solutions are proposed as means for changing travel behavior (Nybom, 2014).…”
