Engineering solutions hold tremendous promise for improving safety for all road users, and particularly for those who are physically more vulnerable. For all of us, the aging process tends to make our bodies less resilient and more prone to injury. This means that the same crash involving a 20-year-old driver might be much more severe if the driver were 85. For the safety of older road users, therefore, there are two imperatives: crash prevention and crash mitigation.

This section is dedicated to promoting lifesaving, cost-effective engineering solutions that protect drivers, passengers, pedestrians, bicyclists, motorcyclists, transit riders, and others. Whether an emerging technology, innovative best practice, or proven and required technical specification, there is likely to be a safer road design element appropriate for any effort to improve overall community safety.
