Info

when data are entered, they are checked automatically for acceptable range values and consistency, enabling quickcorrections when necessary. Several programs continually monitor the data for completeness and accuracy.Periodically, sample cases are analyzed for accuracy and consistency.Note that the FARS data do not include motor vehicle fatalities on nonpublic roads. However, previous NHTSAanalysis found that these fatalities account for 2 percent or fewer of the total motor vehicle fatalities per year. (Seeglossary for highway fatality definition.)Injuries and CrashesNHTSA's General Estimates System (GES) data are a nationally representative sample of police-reported crashesthat contributed to an injury or fatality or resulted in property damage, and involved at least one motor vehicletraveling on a trafficway. Trained GES data collectors randomly sample PARs and forward copies to a centralcontractor for coding into a standard GES system format. Documents such as police diagrams or supporting textprovided by the officers may be further reviewed to complete a data entry.NHTSA suggests that about half of motor vehicle crashes in the United States are not reported to police and that themajority of these unreported crashes involve minor property damage and no significant personal injury. A NHTSAstudy of injuries from motor vehicle crashes estimated the total count of nonfatal injuries at over 5 million comparedwith the GES's estimate of 3.2 million in 1998. (See glossary for highway crash and injury definitions.)(See U.S. Department of Transportation, National Highway Traffic Safety Administration, Traffic Safety Facts 2008,DOT HS 811 170 (Washington, DC: 2009), appendices B and C for further information on GES, including a table ofstandard errors applicable to GES data.)TABLE 2-30. Safety Belt and Motorcycle Helmet UseThe National Occupant Protection Use Survey (NOPUS), conducted biennially between 1994 and 2010 by the U.S.Department of Transportation, National Highway Traffic Safety Administration is the source for these data.In 1994 and 1996, NOPUS consisted of three separate studies: 1) the Moving Traffic Study, which providesinformation on overall shoulder belt use, 2) the Controlled Intersection Study, which provides more detailedinformation about shoulder belt use by type of vehicle, characteristics of the belt users, and child restraint use, and 3)the Shopping Center Study, which provides information on rear-seat belt use and shoulder belt misuse. In 1998, theShopping Center Study was dropped from the survey. The Controlled Intersection Study includes the collection oflicense plate information to link seat belt use to vehicle type. As the results of the Controlled Intersection Study for2000 were not available prior to publication, only the Moving Traffic Study data were used in this table.In 1998, NOPUS separated pickups from the light truck category, thereby creating three categories of passengervehicles: passenger cars, pickup trucks, and other passenger vehicles. Other passenger vehicles include vans,minivans, and sport utility vehicles. In this table, 1998 and 2000 data for pickup trucks and other passenger vehiclesare combined into the light truck category to allow comparison to data from the earlier surveys. Since 2003, however,the National Highway Traffic Safety Administration (NHTSA) no longer computes an overall light truck belt useestimate. Instead, belt use is computed separately for motorists in: (1) vans and sport utility vehicles, and (2) pickuptrucks. Additionally, NHTSA no longer reports separate statistics for passengers and drivers, except at the overalllevel.In 1994, operators and riders wearing any type of helmet were counted as helmeted. In 1996, 1998, and 2000,motorcycle helmets that meet USDOT standards are counted as valid protection, whereas those that do not meetUSDOT standards were treated as if the operator/rider were not wearing a helmet.Data collection from the Moving Traffic Study was conducted at 1,823 sites across the country in 2009. Shoulder beltuse was obtained for drivers and right-front passengers only. Three observers (two observers in 1994 and 1996)were stationed for 30 minutes at interstate/highway exit ramps, controlled (intersections with stop signs or trafficsignals), and uncontrolled intersections. Every day of the week and all daylight hours (7 a.m. to 6 p.m.) were coveredin each survey. Commercial and emergency vehicles were excluded.
NOPUS was designed as a multistage probability sample to ensure that the results would represent occupantprotection use in the country. In the first stage, counties were grouped by regions (northeast, midwest, south, west),level of urbanization (metropolitan or not), and level of belt use (high, medium, or low). Fifty counties or groups ofcounties were selected based on vehicle miles of travel in those locations. In the next stage, roadways were selectedfrom two categories: major roads and local roads. Of the originally selected sites, some were found to be ineligibleduring mapping and data collection, and at some sites no vehicles were observed. In 2006, a newly designed sampleof observation sites emerged; subsequent years’ NOPUS surveys used a combination of sites from the old and newsamples. In 2009, a blend of 65 percent of sites were determined using the new methodology and 35 percent of siteswere obtained from the old methodology. In 2009, a total of 100,000 passenger vehicles were observed, down from116,000 in 2008. 947 motorcycles were also observed during the 2009 NOPUS.Each reported estimate has been statistically weighted according to the sample design. Two kinds of error can beattributed to all survey research: sampling and nonsampling. A measure, called the standard error, is used to indicatethe magnitude of sampling error. The source information provides two standard errors along with each estimate.Nonsampling errors could include problems such as vehicles not counted, incorrect determination of restraint use,and data entry mistakes, among others.TABLE 2-31. Estimated Number of Lives Saved by Use of RestraintsThe U.S. Department of Transportation, National Highway Traffic Safety Administration (NHTSA) uses data obtainedfrom the Fatality Analysis Reporting System to calculate the number of lives saved by the use of restraints. Themethodology used is outlined in a NHTSA report, Research Note, Estimating Lives Saved by Restraint Use inPotentially Fatal Crashes (Washington, DC: June 1995). The general approach is to adjust the observed number offatalities by a determined effectiveness rate for each type of restraint. This equates to subtracting the actual fatalitiesfrom the potential fatalities to determine the number of lives saved. This method is more accurate than earlierestimation methods since all calculations are derived from NHTSA's count of fatalities in which restraints were used.Reported restraint use is believed to be accurate for fatalities.The key to NHTSA's calculations is the effectiveness estimate for preventing fatalities for each type of restraint. Withthe exception of an adjustment in the effectiveness estimate for front outboard air bag-only restraint use in passengercars (NHTSA, Fourth Report to Congress, Effectiveness of Occupant Protection Systems and Their Use,Washington, DC, May 1999), a list of effectiveness estimates can be found in a NHTSA report, Estimating AlcoholInvolvement in Fatal Crashes in Light of Increases in Restraint Use, published in March 1998.This report alsoincludes additional references describing the determination of these effectiveness estimates.TRANSIT DATATABLE 2-1.

In 2008, 692 agencies reported to the NTD.Of that total, 101 transit agencies received exemptions from detailed reporting because they operated 9 or fewer
