Abstract
Public transportation is an essential component of urban mobility, providing affordable and
accessible transport services for daily commuters. This study was conducted along the Sankhu-
Ratnapark Route in Kathmandu Valley with the objectives of identifying the key factors
affecting public transport demand and service adequacy, developing an elasticity-based
demand model, and assessing peak and off-peak demand patterns.
The study adopted a quantitative research approach based on primary data collected through
passenger count surveys, travel time surveys, bus stop observations, and Key Informant
Interviews. A total of 30 bus trips were surveyed, and opinions from 18 transport experts and
stakeholders were collected through KII. Signal-to-Noise Ratio (SNR) analysis was employed
to rank the factors affecting public transport demand and service adequacy. The results
identified Travel Time, Fare, Passenger Waiting Time, Overcrowding and Service Frequency
as the most influential factors affecting public transport demand on the Route.
To quantify the relationship between passenger demand and operational service variables, a
log-log elasticity demand model was developed using multiple regression analysis. The model
achieved an R² value of 0.719 and an Adjusted R² value of 0.687, indicating that approximately
71.9% of the variation in passenger demand is explained by the selected operational variables.
The results revealed that Travel Time, Passenger Waiting Time, and Fare have negative
relationships with passenger demand, suggesting that increases in these variables lead to a
reduction in public transport usage.
The assessment of peak and off-peak demand patterns showed substantial variations in
passenger demand, load factors, waiting times and service frequencies. The study concludes
that reducing travel time and waiting time, maintaining affordable fares and improving service
frequency can significantly enhance public transport demand and service adequacy along the
Sankhu-Ratnapark Route.
