  8. 8. County of Fairfax, Virginia Narrowing Lanes ° AASHTO Green Book (Transportation Engineering Guidebook) — Lane widths may vary from 10’ to 12’. 12’ lanes should be used on higher speed, free flowing, principal arterials — Narrow lanes are adequate and have some advantages for roads under 45mph, with signa| s- similar to Franconia Road ° Several studies suggest narrower lanes have many benefits — NCHRP 330 “Effective use of Street Width on Urban Arteria| s” “all projects evaluated during the study that consisted exclusively of lane widths of 10’ of more resulted in accident rates that were reduced or unchanged. " — Midwest Research Center “Relationship of Lane Width to Safety for Urban and Suburban Arteria| s” “A safety evaluation of lane widths for arterial roadway segments found no indication, except in limited cases, that the use of narrower lanes increases crash frequencies. The lane width effects in the analyses conducted were generally either not statistically significant or indicated that narrower lanes were associated with lower rather than higher crash frequencies. " — Florida DOT completed a study that found there is no measurable decrease in urban street capacity when through lane widths are narrowed from 12 feet to 10 feet. This contradicts the Highway Capacity Manual that shows the capacity of a lane is reduced by 3.33% for each foot of lane width under 12 feet Department of Transportation 397,- CDOT 5 sm. .., ;. i.. /..
