Assume you are an observer standing at a point along a three‐lane roadway. All vehicles in lane 1 are traveling at 30 mi/hr, all vehicles in lane 2 are traveling at 45 mi/hr, and all vehicles in lane 3 are traveling at 60 mi/hr. The spacing between vehicles in each lane is 0.5 mile. If you collect spot speed data for all vehicles as they cross your observation point for 2 hours, what will be the time‐mean speed and space‐mean speed for this traffic stream?
Assume you are an observer standing at a point on a three lane race track. All vehicles in lane 1 are traveling at 50 mi/h, all vehicles in lane 2 are traveling at 65 mi/h, and all vehicles in lane 3 are traveling at 70 mi/h. There is a constant spacing of 0.25 mile. If you collect spot speed data for all vehicles that pass your observation point in one hour, what will the time-mean speed be for the traffic stream?

- Two vehicles, one operated by a human and the other computer controlled, are traveling on a level highway. If the autonomous vehicle is traveling at 70 mi/h, and it receives information at a frequency of 10Hz to respond, what is the maximum speed the human-controlled vehicle can travel and have a practical stopping distance that does not exceed that of the autonomous vehicle? (Assume that grade is zero, driver’s reaction time is 1.5s and autonomous vehicle can decelerate at 15.5ft/s2 )?arrow_forward5. Vehicle time headways and spacings were measured at a point along a highway, from a single lane over the course of an hour. The average values were calculated as 2.5 sec/veh for headway and 200 ft/veh for spacing. What was the average speed? [54.4 mph]arrow_forwardStudies have shown that the traffic flow on a two-lane road adjacent to aschool can be described by the Greenshields model. A length of 0.5 miadjacent to a school is described as a school zone and operates for a periodof 30 min just before the start of school and just after the close of school.The posted speed limit for the school zone during its operation is 15 mi/h.Data collected at the site when the school zone is not in operation showthat the jam density and mean free speed for each lane are 125 veh/mi and57 mi/h. If the demand flow on the highway at the times of operation ofthe school zone is 90% of the capacity of the highway, determine: The speeds of the shock waves created by the operation of the schoolzone, and• The number of vehicles affected by the school zone in the upsream ofthe zone during this 30-minute operation.arrow_forward
