A priority intersection has a single-lane oneway traffic road crossing an undivided two-lane two-way traffic road. The traffic stream speed on the single lane road is $20$ kmph and the speed on the two-lane road is $50$ kmph. The perception-reaction time is $2.5$ s, coefficient of longitudinal ... be $50$ m and $20$ m $61$ m and $18$ m $111$ m and $15$ m $122$ m and $36$ m

Traffic on a highway is moving at a rate of $360$ vehicles per hour at a location. If the number of vehicles arriving on this highway follows Poisson distribution, the probability (round off to $2$ decimal places) that the headway between successive vehicles lies between $6$ and $10$ seconds is ________

A car follows a slow moving truck (travelling at a speed of $10$ m/s) on a two-lane two-way highway. The car reduces its speed to $10$ m/s and follows the truck maintaining a distance of $16$m from the truck. On fining a clear gap in the opposite traffic ... ( from the time it leaves its lane and subsequently returns to its lane after overtaking) is $64$ m $72$ m $128$ m $144$ m

A $7.5$ m wide two-lane road on a plain terrain is to be laid along a horizontal curve of radius $510$ m. For a design speed of $100$ kmph, super elevation is provided as per $\text{IRC:}73-1980$. Consider acceleration due to gravity as $9.81 m/s^2$. The level difference between the inner and outer edges of the road (in m, upto three decimal places is ________
