GATE Civil 2021 Set 2 | Question: 13
Relationship between traffic speed and density is described using a negatively sloped straight line. If $v_{f}$ is the free flow speed then the speed at which the maximum flow occurs is $0$ $\frac{v_{f}}{4}$ $\frac{v_{f}}{2}$ $v_{f}$

GATE Civil 2021 Set 1 | Question: 35
On a road, the speed – density relationship of a traffic stream is given by $u=70-0.7k$ (where speed, $u$, is in $\text{km/h}$ and density, $k$ is in $\text{veh/km}$). At the capacity condition, the average time headway will be $0.5 \:s$ $1.0 \:s$ $1.6 \:s$ $2.1 \:s$

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 distance travelled $d$ (in km) and time $t$ (in hour) for both vehicles are given as P: $d=60 \: t$ Q: ... would be $15$ km at $30$ minutes $15$ km at $15$ minutes $30$ km at $30$ minutes $30$ km at $15$ minutes

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 speeds of the moving observer while traveling along and against the stream are $20$ km/hr and $30$ km/hr, respectively. The density of the traffic stream (expressed in vehicles/km) is _________

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 student (assume the number of vehicles overtaken by the student is zero) during the ride and $45$ vehicles while the student stopped. The speed of vehicle stream on that road (in km/hr) is $7.5$ $12$ $40$ $60$
