The goals of our design program at Grand Canyon, which attracts nearly five million visitors each year, were to reduce car traffic navigating a counter intuitive network of roads, increase shuttle bus use, improve safety information at trailheads, and help orient visitors visiting the South Rim. Designs and plans were developed to direct motorists to parking, provide mapping systems to introduce visitors to the free shuttle bus system, and encourage foot travel with better trail guidance. We also developed an information program for trailheads, campgrounds, and other key locations to educate visitors about personal safety and resource protection.
