RT Journal A1 Runge JW, Cole TB T1 CRosswalk markings and motor vehicle collisions involving older pedestrians JF JAMA JO JAMA YR 2002 FD November 6 VO 288 IS 17 SP 2172 OP 2174 DO 10.1001/jama.288.17.2172 UL http://dx.doi.org/10.1001/jama.288.17.2172 AB Older adults are more likely than any other age group to be killed while crossing a street. Although only 12.6% of the US population in 2001 was estimated to be 65 years or older, these older adults accounted for 1049 (21.5%) of 4882 deaths of pedestrians in motor vehicle crashes in that year.1 Marked crosswalks are often constructed at intersections to enable pedestrians to cross safely. However, an article by Koepsell et al2 in this issue of THE JOURNAL suggests that marked crosswalks might not always be safe for pedestrians.
