An engineering student is driving on a level roadway and sees a construction sign 500 ft ahead in themiddle of the roadway. The student strikes the sign at a speed of 25 mi/h. If the student was traveling at 55 mi/h when the sign was first spotted, what was the student’s perception/reaction time?
2.30 An engineering student is driving on a level
roadway and sees a construction sign 500 ft ahead in the
middle of the roadway. The student strikes the sign at a
speed of 25 mi/h. If the student was traveling at 55 mi/h
when the sign was first spotted, what was the student's
associated perception/reaction time (use practical
stopping distance)?
Calculate the minimum passing sight distance required for a two-lane rural
roadway that has a posted speed limit of 45 mi/h. The local traffic engineer
conducted a speed study of the subject road and found the following:
average speed of the passing vehicle was 47 mi/h with an average
acceleration of 1.43 m/h/sec, and the average speed impeder vehicles was
40 mi/h. Use t1=4.0 and t2=10

- A child accidentally runs into the street in front of an approaching vehicle. The vehicle is traveling at 40 mi/h. Assuming the road is level, at what distance must the driver see the child to stop just in time?arrow_forwardOne vehicle is following another on a two-lane, two-way highway at night according to the safe-driving “rule-of-thumb” of one car length spacing for each 10 mph of speed. Both of you traveling at 70 mph when the lead vehicle crashes into an unlighted disable vehicle. Assuming that one car length is 20 feet, f=0.28 and PIEV time is 1.5 for you, will you hit the lead vehicle? If so at what speed will you be going?arrow_forwardA driver with 20/20 vision traveling at 55 mph in the median lane desires to exit the freeway at the exit ramp. If 5-in. letters are used, what is the minimum distance the sign should be placed ahead of the ramp exit? (Some assumptions that would be helpful are perception-reaction time = 2 sec; exit speed = 30 mph; deceleration rate = 4.80 ft/s2 a driver with 20/20 vision can read a sign at 55 ft per inch of letter height.)

Check if the length of the highway is sufficient for an overtaking maneuver. *Accident Report: Speed of Overtaking Car = 96 kph, Speed of Overtaken Car = 88 kph, Perception-reaction Time = 2.5 sec, Average acceleration = 2.4 m/sec2, Time of the passing vehicle occupying the left lane = 10.4 sec, Distance between the passing vehicle at the end of its maneuver and the opposing vehicle = 84m.arrow_forwardTwo vehicles, one operated by a human and the other computer controlled, are traveling on a level highway. If the autonomous vehicle is traveling at 70 mi/h, and it receives information at a frequency of 10Hz to respond, what is the maximum speed the human-controlled vehicle can travel and have a practical stopping distance that does not exceed that of the autonomous vehicle?

At 10AM, an accident occurs 4 km downstream of an access ramp. The vehicles pull onto the shoulder of the roadway, but traffic passing the accident area slows to 10 kph as drivers survey the damage on the side of the road. A patrol car enters the freeway via access ramp, also at 10AM. Upon entering the freeway, the patrol car notes that traffic on the freeway is moving along at about 40 kph. Determine the following: 1.
