Wireless Inspection Program Highlights

Jeff Loftus
Program Manager, Technology Division

Outline

  • Project Description
  • Need for Improved Inspection Processes
  • Comments from Request for Information
  • Technology Assessment
  • Concept Evaluation
  • Recommended Solution
  • Estimated Costs and Benefits
  • Next Steps

Overall Project Goals

  • Develop alternative concepts to support commercial vehicle inspections
    • Improve the accuracy and efficiency
    • Allow for increase in total number of inspections completed
  • Leverage advanced on-board sensor systems and wireless communication technologies
  • Evaluate concepts relative to
    • Safety impacts
    • Estimated cost of implementation
    • Institutional and policy issues

Current Inspection Activities

  • 3 million roadside safety inspections each year
    • 45 minutes to an hour to complete
    • 1,200 fixed facility inspections stations
    • 1,000 portable/mobile units
  • 73% Violation rate
    • 23% Vehicle Out-Of-Service rate
    • 7% Driver OOS rate

Need for Improved Inspection Process

  • Infrequent inspections
    • Average less than one per year
    • Many CMVs over 10,000 – 26,000 lbs rarely inspected due to operations
  • Current inspection program directed at interstate carriers using tractor-trailers
    • 27% of all CMV fatal crashes involve straight trucks
    • 40% of all CMV crashes occur on secondary roads
  • Inspection program challenged by both volatility and growth in the CMV sector
    • 3.3% annual growth for number of CMVs and VMT
    • 40,000 new entrants annually
    • In last 20 years, 1 million new tractor-trailers on highways

Opportunities for Technology

  • Analysis of historical inspection data reveals that a large portion of significant "defects" are limited to a few items
  • With the exception of load-securement, most of the key vehicle and operator condition criteria lend themselves to on-board electronic monitoring and diagnostic assessment.

Driver Violations% Driver OOS Violations
Logbook40.0%
HOS28.7%
CDL19.4%
Total88.1%

Vehicle Violations % Vehicle OOS Violations
Brakes41.2%
Lighting16.6%
Tires9.4%
Load Securement 15.7%
Total 82.9%

Identification of Items to be Inspected

  • Examination of CMV crash data also completed to help identify items that should be inspected
    • Most crashes linked to driver error
    • While "fatigue" is not directly cited as the "critical reason" for a crash, drivers were cited as being fatigued in a significant portion of CMV crashes
    • Where a vehicle defect was the critical reason for the crash, brakes, tires and load securement issues were most often cited

Critical Reasons in One Truck-One Passenger Vehicle Crashes (FMCSA Large Truck Crash Causation Study)

Bar chart showing critical reasons in one-truck/one-passenger vehicle crashes.  The 'Driver' of the truck represents 88% of the critical reasons; the 'Driver' of the passenger vehicle represents 93%.  The categories of 'Vehicle' and the 'Environment' for truck and passenger vehicle represent the difference.

Request for Information Summary of Comments

RFI issued in September 2005: 27 respondents, including fleets, drivers, OEMS, safety advocacy groups, and the enforcement community

Total27

RFI Responses

  • Communication Standards/Protocols
  • Data Concerns
    • Security, integrity, privacy
  • Data Message Content & Structure
  • End-User Concerns
    • Operator resistance, electronic falsification, O&M
  • Inspection Frequency Level to Change Behavior
  • Implementation Strategies to Equip Every CMV

Technology Assessment

  • Most Viable Option for Wireless Inspection Concepts
  • Dedicated Short-Range Communication (DSRC) at 5.9 GHz
  • 5.9 GHz DSRC has significant advantages:
    • Designed for vehicle-to-infrastructure communications and has high data rates up to 27 Mbps
    • Can support many other safety and "convenience" applications

Concepts of Operation Evaluation

  • Deployment-based
    • Fixed, mobile, virtual, remote, kiosk, etc.
  • Data Message Set-based
    • Basic
      • Driver – License number and log book information
      • Vehicle – Fault codes
    • Enhanced
      • Driver – Fatigue warning, lane tracking, and collision-avoidance systems
      • Vehicle – Brake sensors, tire pressure monitoring

Recommended Wireless Inspection Solution

  • Driver and Vehicle Basic
    • Driver Basic
      • Driver identification, CDL status, and log info
    • Vehicle Basic
      • Fault codes

Wireless Inspection Concept Deployment Plan

  • State and Federal Government
    • 1,200 fixed facility inspection sites
    • 1,000 virtual inspection stations
    • 500 mobile inspection vehicles
    • IT infrastructure (roadside to back office systems)
  • Motor Carrier Industry
    • All CMVs equipped with DSRC and on-board computers

Estimated Costs

  • Public sector annual costs of $45M – $76M
  • Private sector annual costs of $224M – $395M
    • $533 - $940/vehicle
    • 420,000 new vehicles equipped per year

Benefits Assumptions

  • Dramatic Paradigm Shift
    • Electronic safety checks will be frequent and expected
    • Number of unsafe CMV drivers and vehicles on road would be reduced
    • Crashes related to unsafe CMV drivers and vehicle defects would be reduced
  • Size & weight program comparison

Next Steps

  • Conduct proof of concept field tests
  • Develop data interchange and message set standards
  • Partner with states and motor carrier industry to resolve institutional issues
  • Coordinate with ongoing testing and deployment programs (e.g., CVISN grants, I-95 Corridor Coalition efforts, Vehicle Infrastructure Integration program)
  • Investigate broader DSRC applications for trucks and buses
