Ridership Factors Change and Bus Service Demand Sensitivity Assessment of the Fixed- Route Bus Service for Short-term Action Plan

Bus service demand generally raises when bus
service quality attractively increases achieving viable and
reasonable standard. There are many important aspects to
be considered in the increasing bus service demand include
the changes of bus service elements and characteristics of
ridership factors. The study aims to evaluate the change in
ridership factors and to assess the bus service demand sensitivity
with respect to ridership factors change. Primary data on bus
services are collected from the regular stage bus operated in the
mixed traffic at a corridor level and secondary data are compiled
from some resources with respected institution. The study
concludes that the bus service demand responses most sensitive
on travel time elasticity. Meanwhile, some other factors such as
ticket fare, fuel price, per capita income, service frequency, and
headway indicate inelastic factors in the change of bus service
demand. Therefore, especially for current bus system and based
on the short-term period, the bus service demand is not
sensitive with respect to the change in ticket fare, fuel
price, per capita income, service frequency, and headway.
It may change based on those factors and some
circumstances for long-term period.
