Abstract

First-mile and Last-Mile (FMLM) connectivity is critical to ensuring seamless integration within public transport networks. However, accessibility remains challenging due to mode availability, travel cost, and reliability. This study designs and implements a pilot study to evaluate the impact of reliability variables on FMLM accessibility and mode choice in Kuala Lumpur’s rail transit system. The study employs a concept to develop a research instrument by integrating latent constructs and analyzing them in structural equation modelling (SEM). This study also develops the construct by adjusting the attributes in the SP experiment and validating it in multinomial logit (MNL) models. Data were collected through an intercept survey at selected LRT and MRT stations, focusing on socio-demographics, accessibility indicators, and reliability perceptions. Findings indicate that the survey instrument and its variables fulfil the validity and reliability test, although some variables like IF2, AV2, RE5, and PE1 require refinement. The result also shows that availability, Travel Cost, and Travel Time Distance significantly influence Accessibility. The study further highlights discrepancies between stated and actual mode choices, suggesting the need for hybrid models integrating revealed preference (RP) data. Future research should incorporate a longitudinal approach and employ nested logit or latent class models to refine FMLM accessibility models.
