The introduction
The Introduction

  • Perform a cost analysis of the current Residential Trash Collection Route.

  • Use GIS to create a new route that is more efficient and cost effective.

  • Requirement for new route: Garbage truck should only run three days per week.


The data
The Data

  • Roads (from tngis.org)

  • Parcels (from State of TN)

  • City Limits (from Sparta GIS)


The methodology
The Methodology

  • Loaded necessary files into ArcMap.

  • Used “polygon to point” tool to create points from parcel polygons.

  • Used Network Analyst to try to create an efficient route.

  • Loaded points into “stops” in Network Analyst.


The methodology1
The Methodology

  • Set options to re-order stops to optimize route.

  • Crashed ArcMap… 5 times…

  • Decided to resort to old school methods of calculating efficiency… calculator and common sense.


The results
The Results

  • The current routes are being ran 5 days per week (103 miles/week).

  • The current route costs $891.64 per week ($46,365.28/yr).

  • The new, three-day route(80 miles/week) will cost $855.39 per week ($44,480.28/yr).



The results1
The Results

  • 3.4 mph

  • 27 miles/day

  • 3 days/week

  • 649 stops/day (1,947 stops/week)

  • 82 stops/hour (about 45 seconds/stop)

  • 60 miles of road (allowing for 80 miles per week)
