A driver on a level two-lane highway observes a truck completely blocking the highway. The driver was able to stop her vehicle only 10 ft from the truck. If the driver was driving at 70 mi/h, how far was she from the truck when she first observed it (assume perception-reaction time is 2.0 seconds)? How far was she from the truck at the moment the brakes were applied (use a/g=0.35)?
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)
A vehicle pulls out onto a single-lane highway that has a flow rate of 300 veh/h (Poisson distributed). The driver of the vehicle does not look for oncoming traffic. Road conditions and vehicle speeds on the highway are such that it takes 1.7 seconds for an oncoming vehicle to stop once the brakes are applied. Assuming a standard driver reaction time of 2.5 seconds, what is the probability that the vehicle pulling out will get in an accident with oncoming traffic?
In an intersection collision, one of the vehicles leave 165 ft of skid marks. A skid mark analysis indicates that the vehicle was traveling 54 mph at the onset of braking. Assuming the driver’s perception-reaction time is 1.25 seconds, estimate the distance from the point of impact to the vehicle position when the driver initially reacted.
You are to determine the duration of the yellow light at a highway intersection. Assume that cars will be approaching the intersection traveling at 70 mph, and that the reaction time of the driver is 2.5 sec and that cars achieve a deceleration of 1/8 of the gravitational acceleration. if g=32.2 fps^2, a. how long must the traffic light remain yellow to allow drivers to come to stop before the traffic light turns red? b. what is the minimum distance of a car from the intersection when the lightturns yellow to ensure that it comes to a full stop before the intersection?
A driver on a level two-lane highway observes a truck completely blocking the highway. The driver applied the brakes and utilized the maximum longitudinal friction of 0.45 between the wet pavement surfaces and tires. The vehicle stopped only 10 m from the truck. If the driver was driving at 100 km/h, how far was she from the truck when she first observed it (assume perception-reaction time is 1.5 seconds)? How far was she from the truck at the moment the brakes were applied
A test of a driver's perception reaction time is being conducted a special testing track with wet pavement and a driving speed of 55 mi/hr. When the driver is sober, a stop can be made just in time to avoid hitting an object that is first visible 520 ft ahead. After a few drinks under exactly the same conditions, the driver fails to stop in time and strikes the object at a speed of 35 mi/hr. Determine the driver's perception/reaction time before and after drinking. (Assume practical stopping distance)
Problem: Car B is traveling a distance d ahead of car A. Both cars are traveling at 60 ft/s when the driver of B suddenly applies the brakes, causing his car to decelerate at 12 ft/s^2. It takes the driver of car A 0.75 s to react (this is the normal reaction time for drivers). When he applies his brakes, he decelerates at 20 ft/s^2. (Figure 1_ Question: Determine the minimum distance d between the cars so as to avoid a collision. Express your answer to three significant figures and include the appropriate units.
In a stream of vehicles, 20% of the vehicles travel at a constant 50 km/hr, 30% at a constant speed of 80 km/hr and the remaining vehicles travel at a constant speed of 100 km/hr. An observer travelling at a constant speed of 60 km/hr over a length of 6 km with the stream is passed by 10 more vehicles than he passes. When the observer travels against the stream at the same speed and over the same length of highway, the number of vehicles met is 390. What is the mean speed and flow of traffic stream being observed? How many vehicles travelling at 100 km/hr are met by the observer while he travels against the stream?
Calculate the setback distance on a national highway having horizontal curve of radius 300 m and length of 180 m. Assume speed of 80 km/h and coefficient of friction of 0.35 and perception-reactions time of 2.5 seconds.
As a car comes around a bend onto a straight road moving at 80 km/hr the driver suddenly notices another slower car ahead, a distance d = 50 m ahead, moving at 30 km/hr. At this moment, in order to avoid hitting the slow-moving car ahead the driver slows down but takes .25 seconds to react relative to first noticing the car 50 m ahead. Assuming the car decelerates at a constant rate, above what minimum magnitude of the deceleration avoids a rear-end collision? can you solve this with a detailed explanation
A vehicle moving at a speed of 50 mph is slowing traffic on a two-lane highway. What passing sightdistance is necessary, in order for a passing maneuver to be carried out safely? Calculate the passingsight distance. In your calculations, assume that the following variables have the values given: Passing vehicle driver's perception/reaction time = 2.5 sec Passing vehicle's acceleration rate = 1.47 mph/sec Initial speed of passing vehicle = 50 mph Passing speed of passing vehicle = 60 mph Speed of slow vehicle = 50 mph Speed of opposing vehicle = 60 mph Length of passing vehicle = 22 ft Length of slow vehicle = 22 ft Clearance distance between passing and slow vehicles at lane change = 20 ft Clearance distance between passing and slow vehicles at lane re-entry = 20 ft Clearance distance between passing and opposing vehicles at lane re-entry = 250 ft
