<br />• Where the speed limit exceeds 64.4 km/h (40 mi/h). <br /> <br />• On a roadway with four or more lanes without a raised median or crossing island that has (or will <br />soon have) an ADT of 12,000 or greater. <br /> <br />• On a roadway with four or more lanes with a raised median or crossing island that has (or soon will <br />have) an ADT of 15,000 or greater. <br /> <br />GENERAL SAFETY CONSIDERATIONS <br /> <br />Since sites in this study were confined to those having no traffic signal or stop sign on the main street <br />approaches to the crosswalk, it follows that these results do not apply to crossings controlled by traffic <br />signals, stop or yield signs, traffic-calming treatments, or other devices. These results also do not apply to <br />school crossings, since such sites were purposely excluded from the site selection process. <br /> <br />The results of this study have some clear implications on the placement of marked crosswalks and the <br />design of safer pedestrian crossings at uncontrolled locations. <br /> <br />Pedestrian crashes are relatively rare at uncontrolled pedestrian crossings (1 crash every 43.7 years per <br />site in this study); however, the certainty of injury to the pedestrian and the high likelihood of a severe or <br />fatal injury in a high-speed crash make it critical to provide a pedestrian-friendly transportation network. <br /> <br />Marked crosswalks alone (i.e., without traffic-calming treatments, traffic signals with pedestrian signals <br />when warranted, or other substantial improvement) are not recommended at uncontrolled crossing <br />locations on multilane roads (i.e., four or more lanes) where traffic volume exceeds approximately 12,000 <br />vehicles per day (with no raised medians) or approximately 15,000 ADT (with raised medians that serve <br />as refuge areas). This recommendation is based on the analysis of pedestrian crash experience, as well as <br />exposure data and site conditions described earlier. To add a margin of safety and/or to account for future <br />increases in traffic volume, the authors recommend against installing marked crosswalks alone on two- <br />lane roads with ADTs greater than 12,000 or on multilane roads with ADTs greater than 9,000 (with no <br />raised median). This study also recommends against installing marked crosswalks alone on roadways <br />with speed limits higher than 64.4 km/h (40 mi/h) based on the expected increase in driver stopping <br />distance at higher speeds. (Few sites were found for this study having marked crosswalks where speed <br />limits exceeded 64.4 km/h (40 mi/h).) Instead, enhanced crossing treatments (e.g., traffic-calming <br />treatments, traffic and pedestrian signals when warranted, or other substantial improvement) are <br />recommended. Specific recommendations are given in table 11 regarding installation of marked <br />crosswalks and other crossing measures. It is important for motorists to understand their legal <br />responsibility to yield to pedestrians at marked and unmarked crosswalks, which may vary from State to <br />State. Also, pedestrians should use caution when crossing streets, regardless of who has the legal right- <br />of-way, since it is the pedestrian who suffers the most physical injury in a collision with a motor vehicle. <br /> <br />On two-lane roads and lower volume multilane roads (ADTs less than 12,000), marked crosswalks were <br />not found to have any positive or negative effect on pedestrian crash rates at the study sites. Marked <br />crosswalks may encourage pedestrians to cross the street at such sites. However, it is recommended that <br />crosswalks alone (without other crossing enhancements) not be installed at locations that may pose <br />unusual safety risks to pedestrians. Pedestrians should not be encouraged to cross the street at sites with <br />limited sight distance, complex or confusing designs, or at sites with certain vehicle mixes (many heavy <br />trucks) or other dangers unless adequate design features and/or traffic control devices are in place. <br /> <br />At uncontrolled pedestrian crossing locations, installing marked crosswalks should not be regarded as a <br />magic cure for pedestrian safety problems. However, marked crosswalks also should not be considered as <br />52
