Abstract
Mode choice models mainly use socioeconomic and trip characteristics as independent
variables. In addition to the observable variables, the choice of modes of transportation is
also influenced by unobservable or latent factors. This study is aimed at incorporating latent
factors along with observable variables in mode choice models for working commuters in
Lalitpur Metropolitan City. The transportation modes considered in study were private and
public vehicle. In order to collect the travel behavior a structured questionnaire survey was
carried out which consists of questions on socioeconomic characteristics, trip characteristics
and indicator statements reflecting the decision of commuters towards mode choice which
were to be rated by commuters on a five-point Likert scale.
Structural Equation Modeling (SEM) was developed for both modes to identify the latent
factors influencing mode choice decision. Two Binominal Logit (BL) mode choice models
were developed using SPSS version 25. First binomial logit model considered socioeconomic
and trip characteristics as an independent variables. Travel time, travel cost, age and monthly
income, occupation were found to be statistically significant for mode choice of working
commuters. Second binomial logit model considered socioeconomic, trip characteristics and
identified latent factors as independent variables. Travel time, travel cost, age, monthly
income, occupation, reliability, convenience and safety were found to be statistically
significant for mode choice of working commuters. The result of binomial logit model
revealed that incorporating latent factors in the mode choice model, the accuracy of model
was increased.
Finally, the study concludes that in order to achieve higher share of modal split for public
transport, the public transport service providers should improve service quality by increasing
reliability, convenience and safety. The study thus recommends that Lalitpur Metropolitan
City, DOTM and public transport service providers should cooperate among each other to
provide reliable and efficient public transportation.
