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 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)?
One 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?
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?
Q2/ One vehicle is following another on a two lanes, two way highway at night, according to the rule of thumb which allow one car length of spacing per 10 km/hr of speed, if both vehicles are traveling of 100 km/hr and lead car crashes in to the rear of unlighted parked truck, at what speed will the rear vehicle hit the wreckage, assume the perception reaction time of 0.5 sec. and the coefficient of braking friction is 0.5 ,assume length of vehicle is 3.5 m.
A car is approaching toward an intersection with speed 45 mph. The road has a downhill grade of 1%. When the car is at a distance of 250 ft from the intersection, the signal turned yellow. If the driver applies brake and the reaction time of the driver is 1.5 s, will the driver be able to come to a complete stop? Justify your answer with calculations. Assume braking friction coefficient of 0.35.
MCQ (Multiple Choice Question) If the speed limit of a rural two-lane highway is 110 km/h on a straight level segment followed by a horizontal curve with a speed limit 50 km/h. As you a transportation engineering, where should a traffic warning sign to be placed from the beginning of the curve to warn the drivers to reduce their speed knowing that the driver can see the warning sign from 25 m? * O 159.9 m O 184.9 m O 212.9 m O 187.9 m
The length of a highway is 550 m when a head-on vehicle collision occurred. Police reports show that neither human error nor vehicle malfunction was the cause of the collision. 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.
A 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.) Discuss your results.
Two 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? (Assume that grade is zero, driver’s reaction time is 1.5s and autonomous vehicle can decelerate at 15.5ft/s2 )?
Traffic on a freeway gives a Greenshield's traffic flow relationship expressed as: Q = 60k-0.16667k? 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. Capacity flow of the highway 2. Traffic shockwave created by the road accident 3. Time in AM the patrol car will reach the accident zone 4. Plotted traffic shockwave line in the Q-k traffic model diagram
