Concept explainers

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.

Current Attempt in Progress The 3620-lb car is traveling at 25 mi/hr when the driver applies the brakes, and the car continues to move along the circular path.

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)?

(TRAFFIC AND HIGHWAY ENGINEERING)Figure below shows vehicles traveling at constant speeds on a two-lane highway between sections X and Y with their positions and speeds obtained at an instant of time by photography. An observer located at point X observes the four vehicles passing point X during a period of T sec. The velocities of the vehicles are measured as 70, 70, 65, and 50 (km/h), respectively. Calculate the flow, density, time mean speed, and space mean speed.
The reaction time of the average automobile driver is about 0.7sec. The reaction time is the interval between the perception of a signal to stop and the application of the brakes.
