Page 30 of the Rice Signs 2017 Traffic Safety Catalog continues the School and Pedestrian Signs section with in-street and portable crosswalk sign systems. Portable Pedestrian Crossing Signs use weighted bases (typically 30 lb rubber) for temporary deployment at school zones and crosswalks. Roll-Down Pedestrian Crossing Signs (PR-S9 through PR-S15) feature retractable graphics that can be opened or closed depending on whether the sign is in use. Folding Pedestrian Crossing Signs (PR-S19d through PR-S22d, all double-sided) collapse for compact storage between school sessions. All signs are designed to comply with MUTCD R1-6 In-Street Pedestrian Crossing requirements and are fabricated with high-visibility fluorescent yellow-green sheeting for daytime conspicuity.
