Case Study - City of Edmond, OK
Reduction in the number of routes from 40 to 30 resulting
in significant operational savings.
"We chose FleetRoute's
service bureau to develop our routes using GIS route
optimization software because this approach provided
a more economic, sophisticated, and faster solution
than we could develop in-house. The service bureau
gave us valuable access to the FleetRoute Team's extensive
experience in waste collection and advanced route
design. Using the service bureau allowed us to not
worry about the methodology, but rather focus on the
most beneficial routing for the City of Edmond."

Gershman, Brickner & Bratton,
Inc. was hired by the City of Edmond, Oklahoma to completely
re-route the residential collection system in this city of
70,000 people, encompassing 85 square miles. The City provides
weekly automated collection to 22,000 residences using one
or two 105-gallon carts. This project was done on a service
bureau basis as the most cost effective approach for Edmond.
Under the service bureau approach, the City did not have to
buy and maintain the FleetRoute routing software but contracted
for finished routes. The deliverables included:
- detailed route path maps,
- street-by-street travel direction reports,
and
- a customer sequence listing.
The City of Edmond provided
a GIS database with all customers’ addresses matched
to the streets on which they belong, with the side of the
street identified and a customer ID. The City also identified,
by ID, those customers that were exceptions to the norm, such
as:
- customers serviced on the side street (not
the front street where the house address matches to –
a so-called corner customer) and
- customers that require service times other
than the default value. Service time is defined as the elapsed
time from the moment the truck stops in front of a customer
until the moment the truck begins to move again.
Actual scale weight data
was used to assess the set-out size for customers. FleetRoute
was enhanced to control u-turns on major roadways. Also, high
traffic areas and schools were routed so the collection occurs
at specific times during the day. Narrow streets that disallowed
the trucks to turn around were increased in travel time and
displayed as pull-in, pull-out map reports.
The results were a reduction
in the number of routes from 40 to 30 resulting in significant
operational savings.
 In
Task One, the FleetRoute Team developed new optimized routes,
using the FleetRoute™ Route Optimization software, that
didn’t utilize the current collection day of week. Task
Two compared the new routes with routes optimized for current
collection day of week. The outcome of the second task was
that the efficiency improvements were minimal from entirely
switching the current collection day of week to new collection
days. Thus, it was deemed that new routes should be developed
that follow the current collection days, without sacrificing
the time balance between the routes, i.e., maximizing the
efficiency of all of the routes. These routes maintained the
current collection day of week, as closely as possible, while
keeping the routes balanced by time. This new task was the
third task for the routing of the City’s automated trash
collection. The goal in this routing was to allow some modifications
of collection days, but this was minimized to the greatest
extent possible.
Relevant information from
the City’s Tower waste management software (e.g., number
of containers, container size, current day of week service,
etc.) was imported and merged into the FleetRoute customer
database by the FleetRoute Team using the Automated Route
Updater. The City arranged with Transcomp to produce the import/export
file with current account data. An updated Tower file, created
by FleetRoute, was returned to the City reflecting the new
routes.
