The Portland Safe Routes Program document outlines engineering tools to improve safety for pedestrians and cyclists. It discusses conducting outreach, meetings, data collection and design to identify priority routes. Tools include speed bumps, raised crosswalks, curb extensions, refuge islands, beacons, signals, sidewalks and pathways, access management through one-way streets or closures, and bike parking. The overall goal is to focus on crossings and use engineering strategies to manage speed, improve crossing safety, and provide convenient routes and facilities for active transportation.
