  1. Research Project #3 Develop Common Denominators for Safety Measures

  2. Develop Common Denominators for Safety Measures Goals • Develop or identify common denominators suitable for transportation safety measurement • Should be usable within and across various transportation modes

  3. Develop Common Denominators for Safety Measures Scope • Limited to evaluation of exposure measures suitable for transportation safety evaluations • Includes crashes, incidents and injuries to occupants and/or workers

  4. Aviation General aviation Air carrier Highway Passenger car Trucks Transit services Bicycles Rail Passenger and freight Transit systems employing rail Maritime Commercial Recreational Pipeline Develop Common Denominators for Safety Measures Modes Considered

  5. Develop Common Denominators for Safety Measures General Approach • Exposure measures currently used identified • Limitations and gaps of current environment identified, by mode and by type of activity

  6. Develop Common Denominators for Safety Measures General Approach • Recommendations developed to correct for limitations and gaps • Recommendations for exposure measures suitable for intra- and inter-mode comparisons developed • Approaches for implementing findings and recommendations developed

  7. Develop Common Denominators for Safety Measures General Recommendation 1 • General aviation activity survey should be expanded to collect information on: • Number of aircraft occupants • Trip length, miles • Amount of freight carried • Hours on duty for professional pilots

  8. Develop Common Denominators for Safety Measures General Recommendation 2 • A process needs to be developed to capture information from commercial marine operators that would include: • Trip length, miles • Trip length, time • Number of occupants including crew • Hours on duty for crewmembers

  9. Develop Common Denominators for Safety Measures General Recommendation 3 • Highway data collection systems (HPMS, VIUS, NHTS, etc.) should be reviewed to determine accuracy of estimates currently provided. Accurate estimates are needed for: • Trip length in distance and time • Number of vehicle occupants • Total number of trucks operated by commercial operators • Hours on duty for professional drivers

  10. Develop Common Denominators for Safety Measures General Recommendation 4 • An ongoing and systematic survey should be undertaken to collect information from recreation and boat operators on: • Total number of occupants per trip • Trip length in time and distance • Type and size of boat (sailboat, power, etc.) • Number of hours underway compared to time at anchor

  11. Develop Common Denominators for Safety Measures General Recommendation 5 • The National Household Transportation Survey (NHTS) should be conducted more frequently (every two years) to improve timeliness of information. It should also be modified to collect information on: • Recreational use of transportation • Trip length and distance where applicable • Number of occupants • Transportation mode used for recreation

  12. Develop Common Denominators for Safety Measures General Recommendation 6 • The U.S. Department of Transportation should work with State and local authorities to develop a central repository of vehicle operator demographic information derived from operator licenses and other sources. This information should be collected for operators of highway vehicles and transit system vehicles.
