TRAFFIC <br />INFORMATION <br />PROGRAM <br />SERIES <br />CQO&SWALUS <br />WHEN IS A CROSSWALK UNSAFE? <br />Apparently, whenever it is painted on the street! <br />A number of years back, the City of San Diego published some startling results of a very <br />extensive study of the relative safety of marked and unmarked crosswalks. San Diego <br />looked at 400 intersections for five years (without, signals or four-way stops) that had a <br />marked crosswalk on one side and an unmarked crosswalk on the other. About two and <br />one half times as many pedestrians used the marked crosswalk, but about six times as <br />many accidents were reported in the marked crosswalks! Long Beach studied pedestrian <br />safety for three years (1972 through 1974) and found eight times as many reported <br />pedestrian accidents at intersections with marked crosswalks than at those without. <br />One explanation of this apparent contradiction of common sense is the falsesecurity <br />pedestrians feel at the marked crosswalk. Two painted Fines do not provide protection <br />against an oncoming vehicle and the real burden of safety has to be on the pedestrian <br />to be alert and cautious while crossing any street. A pedestrian can stop in less than three <br />feet, while 'a vehicle traveling at 25 MPH will require 60 feet and at 35 MPH <br />approximately 100 feet. <br />The California Vehicle Code says that a crosswalk exists at all intersections unless <br />pedestrian crossing is prohibited by signs. Some of these crosswalks are marked with <br />painted lines,- but most of them are not. Pedestrian crosswalk marking is a method of <br />encouraging pedestrians to use a particular crossing. Such marked crossings may not be <br />as safe as an unmarked crossing at the same location. Therefore, crosswalks should be <br />marked only where necessary for the guidance and control of pedestrians, to direct them <br />to the safest of several potential routes. <br />lM/1-77 <br />6 �- <br />
