| Routing for
New Curbside Recycling System
(Metropolitan Government of
Nashville and Davidson County, Tennessee)
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.

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.
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.
"The team at FleetRoute
worked alongside our operational crews to solve problems,
promote efficiencies, and provide better service to
the citizens. The routing software is user friendly
and extremely flexible"
