| Abstract | Public transit service in Hochiminh City is in the declining process in spite of the efforts of
concerned authorities to improve its performance. Some measures like improvement of amenities,
comfortable inside buses and additional of vehicle fleet, etc. had been implemented without ยท
success. In order to provide a reasonable suggestion for service improvement and future traffic
planning, a study of public transit system had been carried out. Two broad aspects of demand
(considering the commuters' characteristics and their opinions) and supply (considering the transit
operation) were examined. It was believed that distinguished features of operational characteristics
and performance indicators of the best air-conditioned bus and the worst cooperative bus service
routes (indicated by passenger demand) can provide clear insight into problems and deficiencies of
public transit operation.
In addition, the lambretta of locally known as lamb was also selected to present the more
flexible service. It was also believed that the study of commuters' characteristics and their
opinions regarding the levels of service in different aspects can identify the main reasons or
weaknesses of transit service that caused commuters to abandon the services. The services were
examined in terms of six aspects or variables (time consumption, accessibility, safety, comfortable,
crew manner and fare level). A model with utility functions of the six variables and their
coefficients of importance was introduced to integrate utility functions of these variables to an
overall utility function and level of service of the public transit system.
It was found that the most important motive of commuters choosing a certain transit mode
was the convenience in accessing (52%), whereas the existing public transit system in term of
accessibility was evaluated at an unacceptable level. The study had revealed that deficiencies in
route designing and transit system planning had reduced accessibility and attraction of public
transit service. Poor scheduling, lack of proper monitoring and enforcement caused their service
unreliable. It was also found that in terms of time consumption, safety, comfort, crew manner and
fare level, public transit system was evaluated as fair to good levels, whereas overall level of
service was evaluated at a poor level only due to its unacceptable level of accessibility.
Inconvenience in accessing was recognized as the main reason of 48% commuters rejected public
transit service. Poor management at cooperative or company through City level was recognized as
the main reason of the mentioned deficiencies and problems. A study of new transit modes showed
that there was an urgent need to improve performance of the existing transit service rather than
introduce the new transit modes. |
