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

• 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

• 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
