A single-lane highway has a traffic density of 40 vehicles km. If the time-mean speed and space-mean speed are 40 kmph and 30 kmph, respectively, the ...

The lane configuration with lane volumes in vehicles per hour of a four-arm signalized intersection is shown in the figure. There are only two phases:...

For a traffic stream, V is the space mean speed, k is the density, q is the flow. Vf is the free flow speed, and kf is the jam density. Assume that th...

Consider the four points P, Q, R and S shown in the Greenshields fundamental speed-flow diagram. Denote their corresponding traffic densities by kP, k...

A two-phase signalized intersection is designed with a cycle time of 100 s. The amber and red times for each phase are 4 s and 50 s, respectively. If ...

At a traffic intersection, cars and buses arrive randomly according to independent Poisson processes at an average rate of 4 vehicles per hour and 2 v...

The vehicle count obtained in every 10 minute interval of a traffic volume survey done in peak one hour is given below. .tg {border-collapse:collaps...

The figure presents the time-space diagram for when the traffic on a highway is suddenly stopped for a certain time and then released. Which of the fo...

A plot of speed-density relationship (linear) of two roads (Road A and Road B) is shown in the figure. If the capacity of Road A is CA and the capa...

Assuming that traffic on a highway obeys the Greenshields model, the speed of a shockwave between two traffic streams (P) and (Q) as shown in the sche...
