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
Draw the diagram and compute the passing sight distance for the following data:Speed of the passing car = 96 kphSpeed of the overtaken vehicle = 88 kphTine of initial maneuver = 4.3 secAverage acceleration = 2.37 kph/secTime passing vehicle occupies the left lane = 10.4 secDistance between the passing vehicle at the end of its maneuver and the opposing vehicle = 76 m
The distance traveled by the vehicle in the opposite direction is 100 m on two lane two lane roadway. If the acceleration of overtaking vehicle is 3 km/h/sec and time of initial manoeuver is 4 sec. thus the safe overtaking vehicle speed rounded to integer number is ..........km/h
The following are specifications for traffic design of a highway:Speed of the passing car = 100 kphSpeed of the overtaken vehicle = 80 kphTime of initial maneuvers = 5 secTime passing vehicle occupies left lane = 10 secsDistance between the passing car and opposing car at the end of maneuver = 20 mAverage acceleration = 2.5 kph/sec. 1.

Assume you are observing traffic in a single lane of McArthur Highway at a specific location. You measure the average headway and average spacing of the vehicles as 3.2sec. and 50 m. respectively. Determine the traffic speed in kilometer/hour
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?
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.
The speed of overtaking and overtaken vehicles are 70 and 40 kph on a one-way traffic road. If the acceleration of the overtaking vehicle is 0.99 m/s^2, calculate the safe overtaking sight distance.
Compute the minimum passing sight distance for the following data: Speed of the passing car = 90kph Speed of the overtaken vehicle = 80kph Time of initial maneuver = 4 sec Average acceleration = 2.4 m/sec2 Time the passing vehicle occupies the left lane = 9sec Distance between the passing vehicle at end of its maneuver and the opposing vehicle = 80m
The density of traffic in a certain observation point on a highway was recorded to be 30 veh/km. If the space mean speed of the vehicle is 50 kph, how many vehicles will be passing every 20 minutes? OA 255 O B. 750 OC. 50 O D. 500 O E. None of the above
Current Attempt in Progress Car A is traveling at a location where the speed limit is 100 km/h. The police officer in car Pobserves this speed via radar. The driver of car Ais traveling at va - 136 km/h as it passes P, but over the next 5.5 seconds, the car uniformly decelerates to the speed limit of 100 km/h, and after that the speed limit is maintained. At the moment when A passes P, the police car begins to accelerate at the canstant rate of 5.3 m/s? until a speed of 151 km/h is achieved, and that speed is then maintained. Determine the distance s required for the police officer to overtake car A. Answers i
