A pedestrian activated crossing beacon called a Rectangular Rapid Flashing Beacon (RRFB) has been a revolutionary product that is taking North America by storm. The bright LEDs and distinct flash pattern gets drivers to stop for pedestrians like never before. If this technology was implemented at pedestrian crossings with enforcement support it can save lives. This is my recommendation.
Here is a video on how they work: http://carmanah.com/traffic/crosswalk-education-center
