A sign is required to be put up asking drivers to slow down to 30 km/h before entering zone Y (see figure). On this road, vehicles require 174 m to slow down to 30 kmn/h(the distance of 174 m includes the distance travelled during the perception reaction time of drivers). The sign can be read by 6/6 vision drivers from a distance of 48 m. The sign is placed at a distance of x m from the start of Zone Y so that even a 6/9 vision drive can slow down to 30 km/h before entering the zone. The minimum value of x is m.

Car A is traveling at a constant speed vA = 132 km/h at a location where the speed limit is 100 km/h. The police officer in car Pobserves this speed via radar. At the moment when A passes P, the police car begins to accelerate at the constant rate of 4.1 m/s² until a speed of 169 km/h is achieved, and that speed is then maintained. Determine the distance s required for the police officer to overtake car A. Neglect any nonrectilinear motion of P. VA Answer:s= m
A car is traveling at 15 m/s, when the traffic light 60 m ahead turns yellow. If the car decelerates, the time needed to stop the car at the light. 7 secs O 8 secs 5 secs 6 secs
On a six-lane EDSA, an observer is stationed at a certain spot. All of the cars in lane 1 are moving at a speed of 80 kph, 75 kph in lane 2, and 90 kph in lane 3,66 kph in lane 4,70 in lane 5, 65 in lane 6 and 85 for the bus lane respectively. In addition, cars are kept at a constant 65-meter distance between. What will be the time-mean speed and space-mean speed for such a traffic stream based on the acquired spot speed data for all cars as they cross the observation site for 60 minutes?
18 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? A. 255 B. 750 C. 50 D. 500 E. None of the above
Car A is traveling at a location where the speed limit is 100 km/h. The police officer in car P observes this speed via radar. The driver of car A is traveling at VA = 128 km/h as it passes P, but over the next 5.8 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 constant rate of 5.9 m/s² until a speed of 168 km/h is achieved, and that speed is then maintained. Determine the distances required for the police officer to overtake car A. Answer: s= VA P m
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.
Car A travels due east at an initial velocity of 10km/hour then constantly increased in velocity until it reached 50 km/ hour after 40 minutes then it maintained the velocity for the rest of its travel. Car B has an initial velocity of 90 km/ hour and gradually decelerates to a velocity of 60 km/hr after traveling for 20 minutes it then maintained the velocity of 60 km/hour for the rest of its travel time. If car B travels due east 15 minutes after car A started at what distance from their starting?
Car A is traveling at a location where the speed limit is 100 km/h. The police officer in car P observes this speed via radar. The driver of car A is traveling at vÃ = 122 km/h as it passes P, but over the next 4.1 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 constant rate of 4.0 m/s² until a speed of 164 km/h is achieved, and that speed is then maintained. Determine the distance s required for the police officer to overtake car A. Answer: s= i VA 248.52 P m
