National Center for Statistics & Analysis 2 Examples 1. Nopus and Seatbelt Use 2. Electronic Stability Control 3. FARS and Geospatial Coding

National Center for Statistics & Analysis 3 Nopus and Seatbelt Use

National Center for Statistics & Analysis 4 A Primary Use of Traffic Safety Data One way that we use data is to: determine a safety countermeasure, and after implementation of the countermeasure, assess its effectiveness

National Center for Statistics & Analysis 5 An Example One of NHTSA’s priorities is to increase safety belt use.

National Center for Statistics & Analysis 6 Using Data to Identify a Countermeasure Historically, belt use has been lower than average in rural communities, and among pickup occupants:

National Center for Statistics & Analysis 8 Implementing the Countermeasure In 2005, NHTSA chose to focus its Click It or Ticket belt campaign on these two areas – rural areas and pickup occupants:

National Center for Statistics & Analysis 11 Analyzing effectiveness of emerging technology and quickly disseminating results leads to appropriate market response.

National Center for Statistics & Analysis 12 How does ESC function?  Anticipates dangerous situations  Automatically intervenes  Brakes one wheel  Corrects over steer and under steer  Prevents skids, spins  Reduces situations leading to run-off- road and rollovers

National Center for Statistics & Analysis 13 Databases: ESC  FARS,  NCSA State Data  Florida,  Illinois,  Maryland,  Missouri,  Utah,

National Center for Statistics & Analysis 14 Data Sample: ESC Passenger Cars Mercedes-Benz and BMW models – 61 percent Luxury GM models – 23 percent Models from other manufacturers (Acura, Audi, Lexus, and VW) – 16 percent SUVs Mercedes-Benz models (ML320, ML350, ML430, ML500, G500, G55 AMG) – 22 percent Toyota models (4Runner, Land Cruiser) – 41 percent Lexus models (RX300, LX470) – 37 percent

National Center for Statistics & Analysis 15 Analysis Method: ESC  Compute ratios of single vehicle crash involvements (excluding pedestrians, bicycles, animals) to multi-vehicle crash involvements (control group).  Compute percentage reductions in these ratios in vehicles with ESC vs. vehicles of the same make-models without ESC.

National Center for Statistics & Analysis ESC Effectiveness Results In the US, it is estimated that stability control could save 7,000 lives per year. Passenger Cars Sport Utility Vehicles Fatal single vehicle crash reduction 30%63% All single vehicle crash reduction 35%67%

National Center for Statistics & Analysis 17 Resulting Actions  , research leading to rulemaking  In 2005, 20% of new vehicles had ESC as opposed to 10% in  General Motors has announced that by the year 2010, ESC will be standard equipment on all vehicles made.

National Center for Statistics & Analysis 19 The addition of new data element to an existing data system adds a whole new dimension to the use of the data systems.

National Center for Statistics & Analysis 20 FARS Congressional Districts School Districts Air Medical Services Fly Zones Which School Districts have high fatal crash incidents? What are crash rates for Congressional districts? Is there a significant relationship between survivorship and distance to EMS centers? And, a countless number of other traffic safety questions... Primary users of this system are traffic engineers…It is used to identify roadway, signage, design and or traffic signal problems.
