ABSTRACT
The problem of timely collecting and transporting solid waste to the landfill sites in response to environmental pollution and urban beauty is an ongoing concern of many cities. The main objective of this research is to build a GIS database related to the municipal waste transportation in Lien Chieu District, Da Nang City. The traffic data including information about the route systems and their attributes were collected and standardized using the OpenStreetMap (OSM) application. Information about solid waste collection in Lien Chieu District was built based on the field surveys integrating with other referenced data sources. These data were processed in a GIS environment to prepare for waste transported optimization through Network Analyst method in ArcGIS software. The optimal waste transportation route proposed from this study can save the travel time and distance compared to the current route. Especially for the forklift trucks, the waste transported time is reduced by nearly 40 minutes, traveling distance is reduced by about 14 kilometers and the number of transportation trips is also saver compared to the current route. This improvement will increase the efficiency of the waste collection process and reduce environmental pollution. Results from this study can be widely applied for solid waste management in other metropolitan areas where suffering high pressure of population as well as municipal waste growth.
