Why didn’t the senior citizen cross the road? Slower crossings may help people with reduced mobility

Research finds that standard road crossing intervals are too short for older adults with limited mobility, resulting in a need for slower crossings. The study analyzed walking speeds of 1,110 adults aged 65 and over and found that just 1.5% can cross the road within the typical time allowed by pedestrian signals.
