Two sets of students are collecting data at two sections XX and YY of a highway 430m apart. Observations at XX show that five vehicles passed that section at interval 3,4,3,5s respectively. If speed of vihecles were 50,45,40,35,35 kph respectively draw schematic showing locations of vehicles 20s after the first vehicle passed section XX and determine a)time mean speed b)space mean speed c)density of the highway

A freeway traffic stream was observed to have a density of 22.0 veh/mi/ln when the mean speed was 55.0 mi/h. On another occasion at the same location, the jam density was found to be 132 veh/mi/ln. Assume Greenshields' model of traffic flow applies. The optimum speed (in mi/h) is: a) 22.0 b) 33.0 c) 55.0 d) 66.0 e) None of he above
Car A is moving with constant speed v on the straight and level highway. The police officer in the stationary car Pattempts to measure the speed v with radar. If the radar measures "line-of sight" velocity, what velocity v' will the officer observe? Evaluate your general expression for the values v = 78 mi/hr, L= 480 ft, and D = 17 ft, and draw any appropriate conclusions. O Answer: v' = L P mi/hr
For a national highway, the free mean velocity and jam density are 80 kmph and 45 Veh/km respectively. A student mistakenly takes the quadratic relation between the velocity and traffic density in Green-Shield model as shown below: V = All the symbols have the usual meaning. Find the magnitude of error in maximum capacity of the road in Veh/hr (upto two places after decimal)
