OFFICE OF SAFETY Proven Safety Countermeasures Crosswalk Visibility Enhancements Poor lighting conditions, obstructions such as parked cars, and horizontal or vertical roadway curvature can reduce visibility at crosswalks, contributing to safety issues. For multilane roadway crossings where vehicle volumes are in excess of 10,000 Average Annual Daily Traffic (AADT), a marked crosswalk alone is typically not sufficient. Under such conditions, more substantial crossing improvements could prevent an increase in pedestrian crash potential. Three main crosswalk visibility enhancements help make crosswalks and the pedestrians, bicyclists, wheelchair and other mobility device users, and transit users using them more visible to drivers. These include high-visibility crosswalks, Safety Benefits: lighting, and signing and pavement markings. These enhancements can also High-visibility crosswalks assist users in deciding where to cross.

Improved Lighting The goal of crosswalk lighting should be to illuminate with positive contrast to make it easier for a driver to visually identify the pedestrian. This involves carefully placing the luminaires in forward locations to avoid a silhouette effect of the pedestrian.

OFFICE OF SAFETY Proven Safety Countermeasures Leading Pedestrian Interval A leading pedestrian interval (LPI) gives pedestrians the opportunity to enter the crosswalk at an intersection 3-7 seconds before vehicles are given a green indication. Pedestrians can better establish their presence in the crosswalk before vehicles have priority to turn right or left. LPIs provide the following benefits: FHWA’s Handbook for Designing • Increased visibility of crossing Roadways for the Aging Population pedestrians. recommends the use of the LPI at intersections with high turning vehicle • Reduced conflicts between volumes.

OFFICE OF SAFETY Proven Safety Countermeasures Rectangular Rapid Flashing Beacons (RRFB) A marked crosswalk or pedestrian warning sign can improve safety for pedestrians crossing the road, but at times may not be sufficient for drivers to visibly locate crossing locations and yield to pedestrians. To enhance pedestrian conspicuity and increase driver awareness at uncontrolled, marked crosswalks, transportation agencies can install a pedestrian actuated Rectangular Rapid Flashing Beacon (RRFB) to accompany a pedestrian warning sign. RRFBs consist of two, rectangular- shaped yellow indications, each with a light-emitting diode (LED)-array-based light source.1 RRFBs flash with an alternating high frequency when activated to enhance conspicuity of pedestrians at the crossing to drivers. Safety Benefits: For more information on using RRFBs, see the Interim Approval in the Manual RRFBs can reduce on Uniform Traffic Control Devices (MUTCD).1 crashes up to: 47% for pedestrian crashes. 4 Applications The RRFB is applicable to many Considerations Agencies should:2 types of pedestrian crossings but is • Install RRFBs in the median rather particularly effective at
