2 Automated Vehicle-Occupancy Verification Technologies Study HOV Pooled Fund Study California Georgia Maryland Massachusetts Minnesota New Jersey New York Tennessee Virginia Washington FHWA Study Team: TTI and Battelle

3 Addressing the HOV/HOT Enforcement Challenge Automated Vehicle Occupancy Verification (AVOV)

4 Presentation Overview Problem and Need Study Objectives Research Findings

5 Problems with Visual Enforcement Insufficient Accuracy and Reliability Costs and Manpower Requirements Safety Concerns

6 Growing Need for AVOV HOV Lanes

7 Growing Need for AVOV HOT Lanes

8 Projects Under Development I-495 Northern Virginia I-95/395 Northern Virginia I-95 Miami I-10 Houston I-635 Dallas I-30 Dallas I-5 San Diego I-15 Expansion San Diego I-680 Bay Area CA Hwy 101 Bay Area CA I-35W Minneapolis I-10, I-110 Los Angeles

9 Purpose and Objectives of Study Review concepts, methods and technologies for AVOV Identify feasible technologies Develop criteria for improved AVOV Develop path for advancing technology

10 What s Out There Synthesis of Technologies Description of AVOV Systems Roadside In-vehicle Research and Development Overview

11 Roadside Systems Sensing Technologies Viable Technologies Multiband Infrared Systems Infrared Systems Non-viable Technologies Photo and Video Systems Passive Microwave Ultrawideband (UWB) Radar

12 Key Challenges - Roadside Systems Property Visible Light (Passive) Near Infrared Thermal Infrared UWB Radar Microwave Cabin Penetration Environmental Conditions Image Resolution Capture at freeway speed

13 Infrared Composite Imaging University of Minnesota / Honeywell Study, 1998

14 Trends and Outlook: Roadside Viable research and technologies Sensor technologies Faster and cheaper infrared sensors Image processing NIR fusion isolates skin signature Pattern classification No systems in current production Cyclops/dtect

15 In-vehicle Sensing Technologies High Interest Technologies (Near Term Viable) Weight Sensors Capacitive and Electric Field Sensors Optical and NIR Sensors Low Interest Technologies (Near Term Unviable) Biometric Smart Cards Thermal Infrared Imaging Ultrasonic Sensors Smart Cards and Readers

16 3D Time-of-Flight (TOF) Sensors Development Status Pre-production Development Interest Market Forecast Large systems have been researched by IEE, Canesta, Fraunhofer/Siemens, DaimlerChrysler/Conti Temic Wide application foreseen

17 3D TOF Sensor Operation

18 Trends: In-vehicle Systems Sensing Technologies OEM advanced airbag systems will detect front occupants 100% of new vehicles by 2009 Weight sensing Active Optical / NIR, Ultrasonic, Electric Field sensors Increasing monitoring of rear passengers as rear side curtain airbags gain adoption Electric Field sensors Telematics Roadside communications Higher speed in-vehicle networks

19 Key Challenges Accuracy and Reliability Rear Occupant Detection Capability Communications Integration Retrofit Feasibility and Costs Market Penetration

20 Legal and Privacy Considerations Statutory Framework Examination of statutes and case studies related to automated enforcement Legal Issues Legal challenges

21 Privacy Considerations Privacy Concerns Threats Resolving Concerns Photographic record of occupants VII barriers Role of Public Education

22 Findings: Phased Approach Near Term (2-5 years) Growth of HOT lanes provides a market for roadside systems in the near term Use as enforcement tool Engage in VII development Intermediate Term (5-15 years) Legal authority for automated roadside system Continue VII engagement and address public privacy concerns Long Term ( years) VII-based in-vehicle system for occupancy verification
