A road is divided into four sections having varying widths as shown in the figure. Section-$2$ (S$2$) represents a capacity constrained condition with respect to the traf...

Traffic is moving on a $6$-lane dual carriageway road. Traffic volume per direction during peak hour ($08:00$ am to $09:00$ am) is $6000 \mathrm{~veh} / \mathrm{h}$. It i...

Spot speeds of vehicles observed at a point on a highway are $\text{40, 55, 60, 65 and 80 km/h}$. The space-mean speed (in $\text{km/h}$, $\textit{round off to two decima...

Two cars P and Q are moving in a racing track continuously for two hours. Assume that no other vehicles are using the track during this time. The expressions relating the...

Average free flow speed and the jam density observed on a road stretch are $60 \: km/h$ and $120$ vehicles/km, respectively. For a linear speed-density relationship, the ...

The speed-density relationship in a mid-block section of a highway follows the Greenshield’s model. If the free flow speed is $v_f$ and the jam density is $k_j$, the maxi...

The uniform arrival and uniform service rates observed on an approach road to a signalized intersection are $20$ and $50$ vehicles/minute, respectively. For this signal, ...

While traveling along and against the traffic stream, a moving observer measured the relative flows as $50$ vehicles/hr and $200$ vehicles/hr, respectively. The average s...

The radius of a horizontal circular curve on a highway is $120$ m. The design speed is $60$ km/hour, and the design coefficient of lateral friction between the tyre and r...

A student riding a bicycle on a $5$ km one-way street takes $40$ minutes to reach home. The student stopped for $15$ minutes during this ride. $60$ vehicles overtook the ...

The space mean speed (kmph) and density (vehicles/km) of a traffic stream are linearly related. The free flow speed and jam density are $80$ kmph and $100$ vehicles/km re...
