Solution:
Spot speeds of vehicles observed at a point on a highway are 40, 55, 60, 65 and 80 km/h. The space-mean speed (in km/h) of the observed vehicles is
Solution:
The lost time due to starting delay on a traffic signal approach is noted to be 3 sec, the actual green time is 20sec and the amber time is 3sec. How much is the efective green time?

Solution:
An aircraft approaches the threshold of a runway strip at a speed of 200 km/h. The pilot decelerates the aircraft at a rate of 1.697 m/s and takes 18 sec to exit the runway strip. If the deceleration after exiting the runway is 1 m/s, then the distance (in m) of the gate position from the location of exit on the runway is
Solution:
From the floating car method, the following observations were made:
- Average journey time of the test vehicle against the direction of flow: 15 minutes

- Average number of vehicles in the direction against the flow: 76
- Average number of vehicles overtaking the test vehicle: 39
- Average number of vehicles overtaken by the test vehicle: 25
