APPLICATION OF GIS IN IDENTIFYING WATERWAY HAZARDOUS AREA

Abstract

Inland waterway transport (IWT) has been playing a key role in Vietnam's freight transport system. IWT transport routes are often affected by hydro-meteorological characteristics, some routes have bridges and other structures crossing with limited navigational clearances, many sharp/ sudden turns and river bank encroachment. The development of waterways traffic requires improving traffic safety and reducing accidents on the entire waterway. This paper focuses on identifying potential points of traffic accidents in the case of IWT route with one of the actual flow sizes smaller than the minimum value of the technical level based on data analysis application using the Geographic information systems (GIS).
