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

The free flow speed of vehicles on a road section is considered as 80 km/hr and jammed density as 240 veh/km. Estimate the i) traffic density on the road section in maximum traffic flow conditions, ii) possible
maximum flow rate for the road section, and iii) average speed of the vehicles at the maximum traffic volume.

The traffic flow at a highway has an average vehicle time headway of 2 sec at a space mean speed of 60 km/hr. Find the average space headway, flow rate and density for the given traffic flow.
The lane of a 2-lane one way carriageway is closed for repairs. The maximum mean free speed under conditions of low flow in the 2-lane portion is 65km/hr. Under conditions of low flow, observations show that the maximum mean free speed in the bottleneck is also 65km/hr. The average space headway when vehicles are stationary is 12.5m. The volume of traffic on the 2-lane road is 1800 veh/hr. Assuming that the speed-concentration relation is linear, find The mean speed of traffic through the bottleneck caused by the closure of one lane; The mean speed of traffic in the congested conditions immediately on the approach to the bottleneck The mean speed of traffic on the carriageway clear of the influence of the bottleneck The rate at which the queue of the congested traffic enter
