Vehicles moving along a multi-lane road section maintain fixed speeds. Each vehicle, however. moves at its own speed that may differ from the speeds of other vehicles. Vehicle trajectories and speeds in a rectangular area are defined by t = 0 - 1 minute and x = 0 -1 mile (see figure below).

a) Estimate the hourly volume, time-mean speed and approximated space-mean speed from the spot observation at point x = 0.1 mi during the period t = 0 - 1 min

b) Estimate the traffic density and space mean speed from the instantaneous observation at time t= 0.1 min between point x=0 mi and x=1 mi
