22 **Question 22**Given a free flow speed of 70 mph, and an analysis volume (or flow rate) of 2,037 passenger car/hour/lane on a freeway, what is the speed in mph? (Please compute an exact answer and report it with one decimal place)[Answer Text Box]---Explanation:This question presents a scenario involving traffic flow on a freeway. It provides the "free flow speed," which is the speed vehicles travel at under low traffic density conditions, and asks you to compute the speed given a specific flow rate of cars per hour per lane. The flow rate is provided as 2,037 passenger cars/hour/lane.To solve this, use traffic flow principles. The relationship between speed (v), flow rate (q), and density (k) in traffic flow theory is given by:\[ q = k \cdot v \]Where:- \( q \) is the flow rate (cars/hour)- \( k \) is the density (cars/mile)- \( v \) is the speed (miles/hour)Given:- Free flow speed (\( v_f \)) = 70 mph- Flow rate (\( q \)) = 2,037 cars/hour/laneYou will need to use this relationship to find the speed at the given flow rate, ensuring to report the final answer to one decimal place.
