摘要：
To reveal the standee preference for standing areas in urban buses, a multinomial logit (MNL) model of standee preferences was proposed based on the stochastic utility theory. According to standee preference flow and seat arrangement, three key independent factors that affected the preference were introduced, including the looseness of standing, the convenience of getting-off, and the probability of obtaining a seat. The algorithms and thresholds of three factors were proposed, and the distribution law and coupling relationship of each factor among all the standing areas were put forward. The parameters to be estimated in the MNL model were calibrated by Newton iteration method in MATLAB. The typical urban bus of 12 m was taken as a case, and the selection model of each standing area was given based on the investigation data of 22 bus lines in Xi'an. In addition, the standee preference for standing areas under different average standee densities in buses was analyzed. Analysis results show that the calibrated MNL model can effectively reflect standee preferences. The priority of standee for the three independent factors is the convenience of getting-off, the looseness of standing, and the probability of obtaining a seat. There is a coupling relationship of looseness of standing between the two standing areas in the wheelbase. The standee preference for the looseness of standing and the probability of obtaining a seat in the reference area is weaker than that in the non-reference area. When the average number of standing passengers per square meter in the bus is no more than 2, the preference decrease rate of area 3 is 35.95%, while the preference increase rate of area 2 is 19.99%, with a significant phenomenon of coupling. When the average number of standing passengers per square meter in the bus is more than 2, area 2 will significantly relieve the passenger flow in area 1, and the standee always prefers area 1 than area 4. Standee preference for standing areas presents a convergence feature. The study on the standee preference for standing areas is of great value to measure the effect of seat arrangement and passenger flow adaptation, guide the emergency evacuation and diversion of passenger flows, and improve the service quality of urban bus travel. © 2023 Chang'an University.
