1. Demonstrate how the AASHTO Stopping Sight Distance increases for a flat, straight section of highway where the speed limit increases is $60 mph$ if the perception-reaction time $= 2.5 sec$ . 2. Determine if a segment of 700 feet is safe for vehicles to decide to maneuver on a two-lane rural highway of $80 mph$ speed. 3. Determine the required Design Controls when designing for a highway like King Fahad. List examples of each of the 4 parameters.
