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.

A 1500kg vehicle subjected to safety test suddenly hit the brakes and stopped within 50 meters from a velocity of 100 kilometers per hour. If each wheels carries equal braking force, determine the force at each wheel. 50m V1= 100 kmn/h O 2890N O 3012N O 3502N O 3822N O2995N 3320N
A train connection linking Munich airport and Munich city center needs to be optimized. The ride with 11 stops in between takes 41 minutes. Assume that all stops are equally spaced. The train is parking 1 minute at each station. It is driving at a maximum speed of 130 km/h and the maximum acceleration (and deceleration) is determined by the kinetic friction coefficient, which is 0.1 (steel wheels on the tracks). Calculate the distance the train is travelling! Calculate the time the ride would take is there were no stops in between

A car is driving at 75 mph down a 4.0 % grade on poor, wet pavement. The car's braking efficiency is 90%. The driver saw an object which is 480 ft away and applied the brake, and his reaction time was 1.0 second. The car's antilock braking system (ABS) works. Just after seeing the object, which of the following is closest to the distance (in ft) traveled before applying the brake? (Assume theoretical stopping distance ignore air resistance and let yb= 1.04 and fr = 0.015). 153 ft B) 127 ft 135 ft

A car is traveling at 70 mi/h on a level section of road with good, wet pavement. Its antilock braking system (ABS) only starts to work after the brakes have been locked for 100 ft. If the driver holds the brake pedal down completely, immediately locking the wheels, and keeps the pedal down during the entire process, how many feet will it take the car to stop from the point of initial brake application? (The braking efficiency is 80% with the ABS not working and 100 % with the ABS working. Use theoretical stopping distance and ignore air resistance. Let frl = 0.02 when the brakes are locked, but complete the frl once the ABS becomes active.)
