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.

Question

Traffic flow shows the magnitude of the vehicle headway on average 2.2 seconds at a speed of 50 km/hour. Calculate the density and flow rate for this traffic flow.

Traffic on a three-lane (in each direction) freeway observes the following Greenshields flow relationship: V = 60D(1-D/360) where V is the traffic volume on vehicle per hour, and D is the traffic density in vehicles per mile. At 10:00 am, an accident occurs at point A (in the following Figure). The vehicles involved immediately pull off onto the shoulder of the roadway, but traffic passing the incident slows to 10 mph as drivers survey the damage on the side of the road (sometimes called "spectator slowing"). Lucy enters the freeway via the ramp at point B, also at 10:00 am. Upon entering the freeway, she notes that traffic on the freeway is moving along at about 40 mph.
