Transportation Route Optimization of Municipal Solid Waste Using Network Analyst Tool, Case of Jimma Town, Southwestern Ethiopia

Abstract

Municipal solid waste transportation and collection account for the largest portion of its total management expenses. The current study intends to distribute solid waste collection bins and improve the municipal solid waste transportation routes for Jimma town, southwest Ethiopia, using the Network Analyst tool. The coordinates of each municipal solid waste collection container, the coordinates of the disposal location, the town's master plan, its population, the rate at which solid waste is produced, and the road shapefile are the data used for the study. The major piece of software used in this investigation was Network Analyst, an extension of ArcGIS. The recommended quantity of solid waste collection containers, the designated site for the containers, and the most efficient route are among the findings. The calculation's outcome showed that there were 66 municipal solid waste (MSW) collection containers for the 2018 calendar year and 110 containers after 20 years. 17.94 km is the optimal average distance to move filled containers from individual collection container locations to the disposal site and empty containers to their destination. Therefore, route design for municipal solid waste collection vehicles within the urban region is advised by the urban authorities.
