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. |
