Streets designed and operated to enable safe use for walking, bicycling, driving, and transit offer something for everyone. These “Complete Streets” provide safer places to travel and increase physical activity at the same time. In many cases, economic growth is enabled by connecting people to jobs, shopping, and services. Complete streets reflect

Over time, the pavement surface may become polished, thereby reducing the available pavement friction and creating a higher risk of crashes. Also, intersections are locations where friction demand is higher due to slowing, stopping, and turning actions that require an adequate supply of friction. High Friction Surface Treatment (HFST) consists of a
