DEVELOPMENT OF HANOI BUS INFORMATION SYSTEM

Abstract

Public transport is a part of the contemporary urban model. In Vietnam, the bus system is re-established a few years ago. At the same time, some maps have been published for helping the bus passengers. But these maps are still lacked of rich contents and useful functionalities. With the aim to improving the effectiveness of Hanoi public transport system, the authors have applied GIS technology for developing an information system of Hanoi bus. A logical model of the bus network consisting of 2 sub-networks and 5 cost attributes has been designed. This model serves as a basis for developing a bus geodatabase with 5 feature classes. For managing the geodatabase, a set of tools extending the capabilities of ArcGIS software via COM (Component Object Model) interface has been created. The developed information system has very useful functionalities: supplying information about bus stop and bus lines with illustrated photos, searching for streets and specific objects, finding the fastest path by bus between places in the city,... These functionalities will help the bus passengers, especially those in the city for the first time, to be orientated in the complicated Hanoi bus network.
