Metro Nashville and Davidson County, TN – Revolutionizing Recycling Routes

Gershman, Brickner & Bratton, Inc. (GBB), in association with CIVIX L.L.C., was selected by the Metropolitan Government of Nashville and Davidson County to implement a path-routing geographic information system for the new curbside recycling collection using the FleetRoute software. This effort involved obtaining house counts and constructing a GIS database for the 130,000 single family homes in the Urban Services District that were to receive recycling collection from Metro. House addresses were geocoded and the various databases integrated and verified.

Before Optimization

Field verification and observations were conducted before and during the route implementation for greater accuracy. The areas of Nashville were divided into two groups based upon the appropriate type of collection vehicle: automated or semi-automated. Routes also guided the delivery of wheeled carts.

After Optimization

GBB FleetRoute Services provides Metro the following outputs: color driver and management maps; street-by-street and minute-by-minute driving directions, statistical reports for each route, and ad-hoc mapping and analysis for both the automated and semi-automated routes. The routing began in January and the routes were provided to start crew training and testing in March with cart delivery starting in April. Collection on the routes started in May 2002 and fully implemented in November 2002.

The gains for Metro are fewer routes, trucks and crew, lower costs, and a balanced workload. Other benefits included the establishment of a customer service database, which is used by the city wide call center and the adoption of a new street network for use by other City departments.
