Example 4: A driver on a mountain highway with a 7% downslope notices a traffic sign 850ft ahead in the roadway. The driver strikes the sign at a speed of 30mph. If the driver insists that the 60mph speed limit was not exceeded, what would be the associated reaction time for this driver? Assume the deceleration rate a is 3.4 m/s²[11.2 ft/s²].

Intersection Design

An intersection is a location where two or more roads or railways meet or join. The traffic movement is controlled at the intersection that depends on its design and type. It governs the operation, efficiency, speed, capacity, and safety of the highways, airways, and railways. The movement of the pedestrian causes hazards and delays at the intersection.

Question

Example 4: A driver on a mountain highway with a 7% downslope notices a traffic sign
850ft ahead in the roadway. The driver strikes the sign at a speed of 30mph. If the driver insists
that the 60mph speed limit was not exceeded, what would be the associated reaction time for this
driver? Assume the deceleration rate a is 3.4 m/s²[11.2 ft/s²].

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 motorist is travelling at 72km/hr when he observes that a traffic light ahead of him turns red. The traffic light is timed to stay red for 22 seconds. If the motorists wishes to pass the light without stopping just as it tums green again, determine a) the required uniform deceleration of the car in m/s^2 b) the speed of the car in m/s as it passes the light. 320m v = 72km/hr

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 sees and reacts very unwisely to the police car P. Car A is traveling at VÅ = 129 km/h as it passes P, but over the next 4.9 seconds, the car uniformly accelerates to 149 km/h, after which that speed is maintained. At the moment when A passes P, the police car begins to accelerate at the constant rate of 4.4 m/s² until a speed of 177 km/h is achieved, and that speed is then maintained. Determine the distances required for the police officer to overtake car A. A Answer: s= VA P m
While a car is moving with a speed 108 k on a straight road the driver sees a truck which enters the road 75m ahead. The driver applies full brake 0.5s after s/he observes the truck, however the car hits the truck with a speed of 50 k. Then what would be the maximum initial speed of car in when the driver observes the truck in order that the car does not hit the truck with all other conditions are the same?
A car is traveling around a circular track of 660-ft radius. If the magnitude of its total acceleration is 6.2 ft/sec² at the instant when its speed is 32 mi/hr, determine the rate at at which the car is changing its speed. Answer: at = ± ft/sec²
