A colleague of yours comes to you for advice. S/he's working on a project aimed at improving an urban 6-lane freeway section. This person says to you that the traffic flow for one direction during the afternoon peak period is 5,300 vehicles per hour and, according to the loop detectors, the observed time-mean speed was about 45 mph. Her quick estimate seems to show that the specific direction under study operates at LOS=F. Do you agree with her assessment? What is the important assumption about number of vehicles in order for your analysis to be valid? Show all computations. A colleague of yours comes to you for advice.
