Making Safe Systems a Reality: Planning to Implementation (Workshop 1003)

The Safe System (SS) approach is critical for saving lives. Join Nicole Waldheim for this workshop that will explore SS using real-world applications and breakout discussions to define SS for all users, discuss barriers (e.g., data, measures, equity, funding and legal implications) and opportunities for coordination and implementation, share lessons learned, and identify research needs.

User Comprehension of Bicycle Signal Countdown Timers

With an increase in bicycling rates, there is a critical need to invest in active transportation to help create a safer, more connected and accessible transportation system. A key link in the bicycle network is at intersections and crossings. One stressor at intersections is knowing how long one must wait to receive a green indication. In international context, small, nearside bicycle signal heads that contain a countdown timer that visually estimates the amount of waiting time is provided; however, in U.S. context, MUTCD only allows countdown timers for pedestrian signals indicating the duration of clearance interval.

During this poster session, Douglas Cobb, PhD, PE, PTOE, RSP21 will discuss this study which evaluated the comprehension of bicycle countdown timers to determine whether they influence the quality of the cycling experience in the U.S. context.
