Assume you are an observer standing at a point
along a three-lane roadway. All vehicles in lane 1 are
traveling at 30 mi/h, all vehicles in lane 2 are traveling
at 45 mi/h, and all vehicles in lane 3 are traveling at 60
mi/h. There is also a constant spacing of 0.5 mile
between vehicles. If you collect spot speed data for all
vehicles as they cross your observation point, for 30
minutes, what will be the time-mean speed and spacemean speed for this traffic stream?
