Pima County’s Building Inspector
Routing Apps
What is the vehicle routing problem (VRP)?
• Organizations service orders with a fleet of vehicles.
• Need to determine which orders should be serviced
by each vehicle or inspector.
• Default behavior is a least-cost solution.

Automating the Process
• Python script run on a daily basis
• Routes displayed on MapGuide
What Does This Mean?
• DSD inspectors travel 34% fewer miles
• DSD is saving $197,000 per year on mileage and
inspectors’ time
•
• Our Street Network is improved by continuous
feedback from non-geocoded inspections and
addition of turn restrictions
• This model can be used by other departments
Using Esri Navigator
• Navigator 2.0 for iPad
• Navigator for Android (Beta) is available now
On the iPad or Android
Demo 1
Take a look at Navigator for Android
Mobile Map Package
• Create Mobile Map Package (MMP) in Arcgis Pro 1.3
• Symbology important if using your own data
• Create Separate Locator saved with the MMP
• Share the MMP with Navigator Users
• Ability to define Travel Modes (e.g. Walking Time,
Trucking Time)
• Need separate ND without Global Turn delays
Create The Package

• Built using Lat/Lon values from VRP
• Webpage created daily for Inspectors
Individual Route in Navigator
Future
• Use Inspectors Vacation schedule
• Creation of webpage for Customers to see the status of
their inspection
• Analyze routes periodically using Fleetistics to compare
actual vs VRP-generated

Building the Network Dataset
• Builds a speed table first using: subdiv (20mph), stnetall, mt_lemmon poly
(30mph), ajo table, stspeed table
• Build ND next, inputs are: Connectors (5mph), Cochise (5mph), Pinal
(5mph), stnetall, stmisc (5mph), stfclass, Arizona Streets, speed table, urban
polygon (35mph), pinal polygon (45mph), stnoturn
