A vehicle is moving along a straight line having an initial speed of 10 m/s. It is experiencing a deceleration of -0.5v2 m/s2 . Determine the distance travelled by the vehicle after three seconds.

Question A traffic stream in particular direction of a two-lane road moving with a constant speed of 50 km/h. with an average headway of 2.52 s.The longitudinal distance between two consecutive vehicles is

Two cars,on a level surface, are approaching each other from the opposite directions at a speed of 120 kph and 90 kph respectively. The reaction time is 2.0 seconds. Compute the minimum sight distance required to avoid a head-on collision of the two cars. Use 2011 AASHTO formula.
