Models of Traffic Flow (Section 5.4) 5.7 An observer has determined that the time headways between successive vehicles on a section of highway are exponentially distributed and that 65% of the headways between vehicles are 9 seconds or greater. If the observer decides to count traffic in 30- second time intervals, estimate the probability of the observer counting exactly four vehicles in an interval. 5.8 At a specified point on a highway vehicles are
