Mass reduction while holding a vehicle's footprint (size) constant is a potential strategy for meeting footprint-based CAFE and GHG standards. An important corollary issue is the possible effect of mass reduction that maintains footprint on fatal crashes. One way to estimate these effects is statistical analyses of societal fatality rates per VMT, by vehicles' mass and footprint, for the current on-road vehicle fleet. Societal fatality rates include occupants of all vehicles in the crash as well as pedestrians. The analyses comprised MY 2000-2007 cars and LTVs in CY 2002-2008 crashes. Fatality rates were derived from FARS data, 13 State crash files, and registration and mileage data from R.L. Polk. The table presents the estimated percent increase in societal fatality rates per 100-pound mass reduction while holding footprint constant for five classes of vehicles:
|MY 2000-2007 CY 2002-2008||Fatality increase (%) per 100-pound mass reduction while holding footprint constant||95% confidence bounds|
|Cars < 3,106 pounds||1.56||+ .39 to +2.73|
|Cars ≥ 3,106 pounds||.51||− .59 to +1.60|
|CUVs and minivans||− .37||−1.55 to + .81|
|Truck-based LTVs < 4,594 pounds||.52||− .45 to +1.48|
|Truck-based LTVs ≥ 4,594 pounds||− .34||− .97 to + .30|
Only the 1.56 percent risk increase in the lighter cars is statistically significant. There are non-significant increases in the heavier cars and the lighter truck-based LTVs and non-significant societal benefits for mass reduction in CUVs, minivans, and the heavier truck-based LTVs. Based on these results, potential combinations of mass reductions that maintain footprint and are proportionately somewhat higher for the heavier vehicles may be safety-neutral or better as point estimates and, in any case, unlikely to significantly increase fatalities. The primarily non-significant results are not due to a paucity of data, but because the societal effect of mass reduction while maintaining footprint, if any, is small.
This report is also available in two NHTSA dockets—NHTSA-2010-0152-0040 and NHTSA-2010-0131-0336—as well as at http://www-nrd.nhtsa.dot.gov/Pubs/811665.pdf. This final report updates and supersedes a preliminary report issued in November 2011 (76 FR 73008, report available at NHTSA-2010-0152-0023), in response to public comments and to three researchers' peer-reviews of the preliminary report. Information about the public comments and the peer review is available in Docket No. NHTSA-2010-0152, including the peer-review charge at NHTSA-2010-0152-0024, the names of the reviewers at NHTSA-2010-0152-0025, and the three reviews at NHTSA-2010-0152-0035, NHTSA-2010-0152-0036, and NHTSA-2010-0152-0037.
This report also supersedes earlier NHTSA reports on vehicle mass, size and fatality risk issued in 2010 (75 FR 25324, Docket No. NHTSA-2010-0152, report available at http://www.nhtsa.gov/staticfiles/rulemaking/pdf/cafe/CAFE_2012-2016_FRIA_04012010.pdf, pp. 464-542); 2003 (68 FR 66153, Docket No. NHTSA-2003-16318, report available at http://www-nrd.nhtsa.dot.gov/Pubs/809662.PDF); and 1997 (62 FR 34491, Docket No. NHTSA-1997-3725, report available at http://www-nrd.nhtsa.dot.gov/Pubs/808570.PDF).
