Research Reveals Urgent Need for Longer Road Crossing Times

A recent study has highlighted significant discrepancies between standard pedestrian crossing times and the needs of older adults with limited mobility. Research conducted by experts from the Universities of Bath, Birmingham, and Exeter reveals that the typical crossing time in the UK is more than two seconds shorter than what is necessary for many older pedestrians to cross safely.

Led by Dr. Max Western from the University of Bath Centre for Motivation and Behaviour Change, the study analyzed the walking speeds of over 1,100 adults aged 65 and older. Findings indicate that only 1.5% of older adults with mobility limitations can walk at a speed sufficient to cross within the time allowed by pedestrian signals. The average walking speed recorded was a mere 0.77 meters per second, significantly below the 1.2 m/s standard typically assumed in pedestrian crossing designs.

The implications of this research are profound. An average participant would require approximately 6.5 seconds to cross a 5-meter road, which exceeds the typical green signal duration. This discrepancy not only raises safety concerns but also poses a barrier to independence, physical activity, and social engagement for older adults, all of which are crucial for quality of life.

Understanding the Challenges

The study found that factors such as older age, decreased strength, and balance issues contribute to slower walking speeds among older individuals. Notably, over half of the participants would need to increase their comfortable walking speed by 50% or more to cross safely within the existing time limits.

Professor Afroditi Stathi from the University of Birmingham, who leads the two trials underpinning this research, emphasized the importance of designing inclusive outdoor spaces. “Older adults often face challenges staying active and connected, especially when mobility is reduced,” she stated. “Designing outdoor spaces that work for everyone, such as allowing enough time to cross the road, can boost confidence and support independence.”

A Call for Action

The researchers advocate for changes to pedestrian crossing times to reflect more realistic walking speeds. They propose extending green signal durations to accommodate a walking speed of 0.7 m/s, which would enable more older adults to cross roads safely and confidently.

While innovations like smart crossings and countdown timers are emerging, the research team warns that these advancements may not reach those most in need without targeted public awareness and inclusive design practices.

The study calls for urban design standards that incorporate slower walking speeds and enhance pedestrian safety features. Such adjustments would help ensure that older adults can navigate their communities more easily. Additionally, integrating mobility support into public health strategies is essential. Creating age-friendly outdoor spaces with safe walkways, benches, and extended crossing times can encourage regular physical activity among older adults.

The findings are detailed in the paper titled “Why didn’t the senior citizen cross the road? Gait speed in community-dwelling older adults with mobility limitations relative to pedestrian crossing times,” published in Age and Ageing on December 8, 2025. This research builds on data from two NIHR Public Health Research Programme grants, providing critical insights into the mobility challenges faced by older adults.

By addressing these issues, communities can foster an environment that supports the independence and well-being of older residents, ultimately enhancing their quality of life.
