Snow Plow Tracking from Start to Finish GIS-T 2014
Iowa Department of Transportation
Eric Abrams – Iowa DOT
Agenda
Why track plows
Understand current technology and processes
Plow Cam Project
Questions
Winter Operations Facts
901 Snow Plows
9,479 centerline miles of road
24,215 lane miles of roadway
24,735,773 gallons of brine used during 2013-2014 winter season
185,058 tons of salt used during 2013-2014 winter season
2009 – Looking at Cost Control
High cost of salt
Strained budgets
Laborious record keeping
Auditing the REAL use of materials
Response consistency
Impact of winter operations on pavement asset
ROI Done
Every dollar spent on AVL returns $6.40
A 10% reduction of salt is $1.4 million dollars in savings
Not everything that can be counted counts, and not everything that counts can be counted.
-Albert Einstein
Start of project in 2010 - RFP Understand & visualize
Fleet Movement
Material Usage
Give Supervisors tools to direct fleet
Drivers less paperwork
Give public a better winter driving experience
Turn plow data into information
Vendor with open architecture Web services
Access to data
Implementation Lessons – 2011/12
Wanted – Phase 1 Driver to log into the system
Report road conditions
Integrate with resource system
Deployed 25 trucks
Computer to manage touch screen
Custom database
Learned Pulled back to only a modem
No driver interaction
Able to pull real-time truck information
Winter of 2012/13
Only Modem (LT6 unit)
Make the system invisible to the driver
Standardized spreader controllers
Install on all plows
More robust database architecture
Mobile web site
Begin integration with resource management systems
Winter of 2013/14
Mobile Web site adoption
Public access to data Travelers
researchers
Photos from truck Minor adjustments to architecture
Technical Architecture
Open vendor data Access to raw data for Iowa DOT processing
LTI as a vendor (https://www.loctech.com/)
Technology Used Oracle

Future Enhancements
Full Public rollout of plow data Continuous improvement of system Full ESRI REST access Expanded Plow Cam Analytics
Plow Cam Objective
Identify and implement readily available technology to capture, upload, and geographically display photos taken from snow plow vehicles during winter operations
Cameras Considered
Existing GPS/AVL and Brigade camera
IPhone
Internet protocol (IP) camera and modem
Camera Criteria
Quality of photo
Availability of hardware
Availability of software/application
Multi-functionality
Simplicity
Unobtrusiveness
Connectivity and data transfer
Cost
Implementation-Timeline
Phase 1 Phase 2 Phase 3 Internal Internal Internal/External
2 rural shops District 1 (Central Iowa)
All Districts
7 IPhones 100 IPhones 200 IPhones Nov-Dec 2013 Dec 2013 –
Feb 2014 Feb 2014 – Current
Executed soft release of Plow Cam Photos on Public facing website during Blizzard event on 20-21 February 14.
Pilot 6 Month Cost (200 Installs)
IPhone 4s = $0.00
Application = 200 hours staff time - $10,000.00
GIS = 200 hours staff time - $10,0000.00
Mounts & Wiring - $50 per truck Total initial = $30,000.00
Unlimited data plan = $40.00 / month / IPhone Total monthly = $8,000.00
Total = $78,000.00
Findings Many uses
Situational awareness
Operational/treatment decisions
Roadway/travel conditions
Performance analysis
Research
Positive field acceptance
Positive public response
Simple
Adaptable
