...So far most efforts to improve bicyclist safety have focused on infrastructure. Cities have added bike lanes and cycle tracks and have delineated bike boxes at intersections to give bicyclists their own space to wait for a light to change. In many cases, safety was found to improve after such changes (see "Sharing the road: Communities try new ways to improve bicyclist safety," Jan. 24, 2013).

But even with improved infrastructure, it would be impossible to eliminate all conflicts between vehicles and bicycles. That's why it's important to incorporate bicyclist detection into front crash prevention systems.
