(a) The following relationship between traffic speed and flow applies to a particular urban highway:- q=192u - 44u In u where q = flow in veh/hr. u = speed in km/hr. Calculate the following:- (i) (ii) (iii) The mean speed when the highway flow is at maximum capacity The capacity of the highway The density at maximum flow capacity

Q: A freeway has the following relationship: S = 75.4e- where S' is in mph, for D pc/mi/ln (D<145), b…

A: Free flow relation- S=75.4e-bD  (D&lt;145)Vm (capacity) = 2500 pc/h/lnD0=45 pc/mi/lnTo determine -…

A: 6) If we consider 3 points within a mile of a road then we will find that if at a certain point u is…

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.
