Painted medians can never be considered a refuge for a crossing pedestrian. Similarly, a 4 foot wide raised median next to a left turn lane can only be considered a refuge for pedestrians <br />if the left (timing volume is less than 20 vehicles per hour (meaning That In most cases the left tum lane is not occupied while the pedestrian is crossing). <br />2. A multiple threat lane is defined as a through lane where it is possible for a pedestrian to step out from in front of a slopped vehicle in the adjacent travel lane (either through or turn lane). <br />Treatment Descriptions: <br />A Install marked crosswalk with enhanced <br />Specific Guidance: Install marked crosswalk <br />road -side signs <br />with "State Law - Yield to Pedestrian" signs mounted on the side of the roadway with standard (W11-2) <br />use S1-1 signs for School Crossing locations. <br />advance pedestrian warning signs; <br />B Install marked crosswalk with enhanced <br />Specific Guidance: Install marked crosswalk <br />road -side and in -roadway (bollard mounted) signs <br />with "State Law - Yield to Pedestrian" signs mounted on the side of the roadway and on in -roadway <br />pedestrian warning signs; use S1-1 signs for School Crossing locations. <br />bollards; use standard (W11-2) advance <br />C Install marked crosswalk with enhanced <br />Specific Guidance: For 2 or 3-lane <br />signs and geometric improvements to increase pedestrian visibility and reduce exposure <br />roadways, install marked crosswalk with "State Law - Yield to Pedestrian" signs mounted on the side of the roadway <br />mounted signs; use standard (WI1-2) advance pedestrian warning signs; use S1-1 signs for School Crossing <br />refuge islands to shorten the pedestrian crossing distance and increase pedestrian visibility to motorists. <br />and on in -roadway bollards or median <br />locations.
