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.
