Note: The complete program is tested and the output is attached, please wait the table is being updated. I will attach once it is done.
Stopping sight distance (SSD) is defined as the distance needed for a driver to see an object on the roadway and t...
What is the minimum stopping sight distance (SSD) that should be provided on a highway that has a design speed of 75 mph and a maximum grade of -6%? Assume the perception reaction time = 2.5 sec.
1. Find the stopping sight distance (in feet) for traveling downhill at a grade of 3% and speed of 60 mph, assuming driver’s perception and reaction time of 2.5 sec and a deceleration rate of 9.3 ft/s2. 2. A temporary diversion has been constructed on a highway of +3% grade due to major repairs that are being undertaken on a bridge. The maximum speed allowed on the diversion is 25 mi/h. Determine the minimum distance from the diversion that a...
While a car was operated at 60 mph on a freeway, the driver saw a box on the road ahead and tried to stop the car. The highway grade is -2%. Assume the maximum deceleration rate of the car is 11.2 ft/sec^2 and the perception-reaction time is 2.5 sec. Calculate the stopping sight distance.
please show steps 3. Stopping Distance: You are traveling at 70 mph on a slushy road (friction coefficient 0.20) when you hear a train whistle. You then see the warning sign that is placed 1000 feet before the gate-protected railroad grade crossing. You know you must try to stop. How close will you be to the gate when you come to a stop? Your reaction time is 1.5 seconds. [F&W 6.18 1976.43 ft]
