e-Ticketing
The Basics
e-Ticketing Goals
• Reduce inspector workload• Improve data collection
and data recording• Allow inspectors to focus
on most demanding tasks
e-Ticketing Opportunities
DOT
• Web based exchange of material information
Contractors
• GPS/GIS system for fleet tracking and management
How it works
• Cigarette Lighter Adapter– Internal Battery Backup
• Mobile app on smartphones• Ping every minute on haulers• Ping every 30 seconds on pavers/mills• Fee is per truck, no user fees or special software
required
Geozones, Subzones, Geofences
Cycle Time Capability
Daily Shifts
Analyzing Shifts
General Benefits
Real-time Electronic Information Easily sorted and analyzed
Potential to automate processes (shifts, payment, estimates, etc.)
Quick and easy set-up
Web-based
Mobile apps
Works with company or brokered trucks
Other BenefitsDOT
• Safety• Electronic storage of
tickets• Electronic quantity tracking• Advanced review of
delivery• Expedites pay
Contractor
• Data for trucking payroll• Real-time fleet
management• Eliminate bottlenecks at
plant and paver
National Use… more on this later
e-Ticketing
KYTC’s Journey
KYTC’s First Pilots
• MTV• 7,000 tons• 3 rollers• Cores taken• Special Note
• No MTV• 3,000 tons• 2 rollers• No cores taken• Special Note
Collaborative Technologies
Inspection Operation Inspector Responsibility Assistive Technology
Ticket Receipt and Acceptance Collect Tickets
Tracking Theoretical Tonnage (Yield)
Determine theoretical tonnage by station
Temperature Monitoring in the Truck Bed and Paver Hopper
Take temperature readings as normal
Temperature Monitoring behind the Paver and Screed
Take temperature readings as normal
Monitoring Roller Operation Check as normal
Communicating with Contractor QC for Nuclear
Density MeasurementsCheck as normal
Theoretical Tonnage with e-Ticketing
Theoretical Tonnage = Mix Density * Pavement Thickness * Pavement Width * Pavement Length
Paver Mounted Thermal Profiler
• Highly accurate compared to IR shots
• Temperature variations more visible without material transfer vehicle (MTV)
• Speed of paver directly impacted temperature of mat
Temp vs. Speed (no MTV)
Temp vs. Speed (with MTV)
Intelligent Compaction
• Temperature at Breakdown
• Roller pass counts
• Roller speeds

• National Trends• A lot of DOT interest…
• Many states piloting• States trying new materials and…
• Looking for an enterprise solution• A lot of vendor competition
• Moving to systems without hauler tracking• Pros & Cons
Considerations for Instituting e-Ticketing
• You need buy-in• Can you have partnership without knowing who your
stakeholders are?• Is your agency (& field staff) ready?• Is you industry ready?• What material(s) will you focus on?• Will the solution provide material tracking?
• Does this entail 3rd party haulers?• Is there liability in tracking (speed histories, etc.)?
Considerations for Instituting e-Ticketing
• How will data be transferred and who owns it?• Is there a vendor that fits your needs?
• Will staff need training for multiple technologies?• Will you consider an in-house developed solution?
• Will the data integrate into your contract admin system?
• Is there a bill of lading (electronic)?
Considerations for Instituting e-Ticketing
• How will you procure the solution?• Is there a good place to start a pilot?
• Willing industry, good connectivity, technology savvy staff
• Will contractors want to know how data is going to be used?
• Is this a single pilot or is there a scale up plan?
Forthcoming Research
• NCHRP Project 03-140• Guidelines for Applications of RFID and Wireless Technologies in
Highway Construction and Asset Management• Continued e-Construction and EDC efforts
e-Ticketing and the Impacts of COVID-19
• Rapid implementation of many electronic aspects• Moves to contactless & paperless• e-Signatures rapidly adopted• Pilot e-Ticketing to statewide use
• Pressure on e-Ticketing (and other electronic tool) vendors• Rapid increase in number of vendors
• Some barriers seems to fade

Cell Service Limitations
Advertisement Considerations
No Advertisement Considerations Currently● Made decision not to force this on anyone● Find willing participants (COVID 19 has helped)● Grow momentum by positive experiences ● Get the largest Asphalt products suppliers in Utah comfortable with
the system before considering advertising● Possible advertisement including eTicketing by fall 2020

Benefits to Contractor
● Near real time quantities● Itemized Delivery Information
○ (Truck # / Qty / Temp / Notes / Location)● Verify / Reconcile Truck Tickets (Hrs & Loads)● Creates data analytics for better understanding of cycle
times, trucking efficiencies/inefficiencies, etc.
Partnering with Industry
● Initially presented to the URMCA○ UDOT only consists of about 2% of their business○ Hard no○ WW Clyde – PCC pilot project
● UAPA ○ Presented to UAPA with a much better response
■ No new commercial software in batch plants■ No mandation of software/hardware in trucks
○ Granite Construction (Scott Fernald) was first volunteer○ Bruce Jacobsen Enterprise Architect with Granite Construction
Pilots (2019)● 7 Projects with Granite
○ 2,900 tickets for 70,000 tons● 1 Project with Staker-
Parson● Pilot PCC with Geneva
2020 Projects (as of today)
● 11 Projects with Granite○ ~174,000 Tons
● 16 Projects with Staker-Parson○ ~313,000 Tons
● 12 Projects with WW Clyde● Upcoming test Projects with Kilgore
Companies
Concerns● Supplier vs. Prime
○ How does this process work when the Prime is not also the material Supplier?● Bypassing Port of Entries
○ A paper ticket is required in Utah to bypass a port of entry while hauling material● Automation/Scalability
○ Finding ways to create projects when an order is sent to a seperate REST endpoint○ Server capacity if all UDOT projects are using eTicketing
● Enterprise Architecture○ Guidelines for solving problems○ Data Governance
Institutionalization and Expansion on Future Projects
● Create a Standard Operating Procedure○ Document best practices for eTicking at UDOT○ Contact list for project administrators○ Keeping up with new projects
eTicketing Expansion Potentials● PCC
○ WW Clyde is sending PCC tickets○ Much more complex data structure and Integration into
other Department Systems○ Create real time W/C ratio tickets
● Aggregates○ Can we implement the same system?
