It takes about 3 s for a driver having 0.1% alcohol in his system to react to a situation to avoid a collision. If such drivers are traveling on a straight road at 45.5 ft/s and their cars can decelerate at 2.64 ft/s^2, determine the shortest stopping distance d (in feet) from the moment they see the pedestrians. The Correct answer is 528.59. Show solution.
Assume you are observing traffic in a single lane of a highway at a specific location. You measure the average headway and average spacing of passing vehicles as 3.2 seconds and 20 m, respectively. Calculate the flow, average speed, and density of the traffic stream in this lane.
Give the Greenberg's speed-density relation equation for the following traffic data.
what distance (in meters) does the car travel during this time? PROBLEM 2: A bicyclist starts from rest and after travelling along a straight path a distance of 20m reaches a speed of 30 km/hr. Determine his acceleration (m/s²) if it is constant. Also, how long (in seconds) does it take to reach the speed of 30 km/hr?
