10 Priority SHSP 8.5 Pedestrian Safety Data Task Force q An outgrowth of the Strategic Highway Safety Plan (SHSP), Challenge Area 8 Make walking and street crossing safer q Effort began in the summer of 2008 q q Collaboration between CDPH and multiple agencies Holly Sisneros, MPH, PedSafe Program, California Department of Public Health 10

11 The Task Force Directive Priority 5: Establish a Caltrans-led Pedestrian Safety Data Think Tank to develop and implement a comprehensive Pedestrian Safety Data Plan which: improves and institutionalizes pedestrian safety data collection and analysis ensures that existing data collection efforts include data on pedestrian fatalities, injuries and exposure implements a readily available format for local research and investigation. 11

12 Task Force Participants Consists of scientists and other experts from several key agencies, including: ª ª ª ª ª ª ª ª ª Caltrans California Department of Public Health (Lead) California Office of Traffic Safety California Department of Motor Vehicles California Highway Patrol California State Automobile Association Federal Highway Administration National Highway Transportation Safety Administration UC Berkeley SafeTREC 12

13 Underlying Goals Evaluation and improvement of data Improved access to data Improved analysis of data Institutionalization of data collection and management

14 Data Categories Pedestrian Crash Data Pedestrian Injury Surveillance Data Pedestrian-Related Infrastructure Data Pedestrian Exposure Data Driver Data

15 Purposes of Crash Data Determine the burden of traffic collisions Identify trends and patterns Determine causal factors Plan, implement, and evaluate countermeasures

16 Purposes of Injury Surveillance Data Determine magnitude and patterns of injuries Determine under-reporting Planning for medical response Determine effectiveness of medical response Evaluate methods to control energy transfer

17 Purposes of Infrastructure Data Track infrastructure status Conduct maintenance Evaluate capacity Identify high risk locations Basis for resource allocation Comply with ADA

18 Purposes of Exposure Data Determine the amount of walking (or mode share) Determine risk (collisions, injuries or fatalities per unit of exposure) Compare risk across groups, geographic areas and types of roadway Evaluate trends over time Assess the impact of countermeasures.

19 Purposes of Driver Data Identify characteristics of drivers involved in pedestrian crashes Identify drivers who may be at high risk for being involved in a pedestrian-related crash Support new/revised laws

20 Purposes of Linking Data Crash data + Infrastructure data + Exposure data Risk analysis Spatial analysis Countermeasure analysis

21 Recommendations were mostly about: Improving data (amount and quality) Analysis and modeling Linking Improving access

22 Top Four Recommendations Recommendation Rank Analyze 2009 Na-onal Household Travel Survey, California Add- On Data Train police on appropriate procedures for coding pedestrian crashes as part of the POST program and Collision Inves-ga-on Manual Support Current Research Efforts to Develop Coun-ng and Modeling Methods for Pedestrian Exposure on the State Highway System Conduct a study to iden-fy the rate of pedestrian crash underrepor-ng in the SWITRS database

28 #2 Train police on appropriate procedures for coding pedestrian crashes as part of the POST program and Collision Inves-ga-on Manual Information on the circumstances of the collisions may be inadequate to evaluate causes and identify appropriate countermeasures. Depends on revision of CHP 555 Form (i.e., Collision Reporting Form) Depends on strong advocates within enforcement 28

29 Improving Police Collision Report (e.g., CHP 555 Form) CALPED Task Force (after lengthy process) proposed changes to the CHP 555 collision report The issue was taken up by CA 08 (Pedestrian)

40 Topics Pedestrian Fatal and Severe Injury in California Pedestrian Data Task Force #1 Priority: Analyze 2009 National Household Travel Survey, California Add-On Data #2 Priority: Train police on appropriate procedures for coding pedestrian crashes as part of the POST program and Collision Investigation Manual #3 Priority: Support Current Research Efforts to Develop Counting and Modeling Methods for Pedestrian Exposure on the State Highway System #4 Priority: Conduct a study to identify the rate of pedestrian crash underreporting in the SWITRS database Underlying Goal Institutionalize Pedestrian-Related Data 40

41 Underlying Goal Institutionalize Pedestrian-Related Data To make something an established custom or an accepted part of the structure of a large organization or society (Encarta)

42 Modes of Institutionalizing Pedestrian Data Laws (e.g., MAP-21) Funding Streams (e.g., Safe Routes to School, Rural Highway Safety) Design manuals (e.g., AASHTO Green Book, MUTCD) and traffic engineering manuals Professional Training (e.g., Planning, Traffic Engineering) Data Bases (e.g., collisions, volume)

43 Highway Safety Improvement Program NPRM The FHWA proposes to revise the definition for the term highway to match the definition of 23 U.S.C. 101(a) and clarify the provision that HSIP funds can be used for highway safety improvement projects on any facility that serves pedestrians and bicyclists pursuant to 23 U.S.C. 148(e)(1)(A). 43

44 National Performance Measures NPRM Comment Received The FHWA should define performance measures that specifically evaluate the number of fatalities and serious injuries for pedestrian and bicycles crashes. The FHWA should require that bicycle and pedestrian crashes and fatalities be reported nationally and by State and MPO. 44

45 National Performance Measures NPRM Comment Received The FHWA should account for the safety of all road users by including separate measures for motorized and non-motorized (e.g., pedestrian, bicycle) transportation. Having separate measures will allow State DOTs to utilize some HSIP funds on non- motorized transportation without any detriment to safety efforts for other road users. 45

46 Sum Several categories of data, many sources Purposes/needs for data are clear Large number of activities around the state (evidenced by this Conference) A great deal of work to do!
