Abstract

Rapid urbanization in the Kathmandu Valley has intensified travel demand, placing significant strain on transport infrastructure along the corridor connecting two UNESCO World Heritage Sites, where narrow historic streets and limited last-mile connectivity create unique accessibility challenges. This study assessed multimodal transport accessibility by incorporating traveler preferences into the analysis using a nested logit modeling framework supported by revealed preference and stated preference survey methods. Data were collected from travelers along the study corridor, with four distance- based travel scenarios established through geographic information system analysis. Nested logit models were estimated for each scenario to derive mode choice probabilities, values of time, and generalized cost measures. The analysis revealed that travel time, monetary cost, walking duration, transfer time, and traveler gender consistently influenced mode selection across all distance conditions. Combined bus and last-mile (tempo and cycle) options captured a notable portion of traveler preferences, particularly for moderate-length trips, while personal two-wheelers remained a strong contender across most scenarios. Values of time varied considerably across transport options, with private modes commanding higher valuations than public transport alternatives. Generalized cost estimates indicated that integrated multimodal options offered the lowest overall travel burden, reflecting their superior accessibility. Comparative scenario analysis revealed that multimodal combinations perform best when travel duration falls within a moderate range and transfer time constitutes a small fraction of the total journey. Based on these findings, interventions such as reducing transfer, walking time, and optimizing travel duration were identified as effective strategies for enhancing multimodal competitiveness. This study contributes to understanding how traveler preferences shape multimodal transport accessibility along heritage corridors and offers practical guidance for developing sustainable transport solutions in heritage contexts.
