Question

A traffic pacing operation was conducted by a highway patrol unit (see Figure
Q2(a)) to slow down upstream traffic on a highway due to maintenance works
being conducted downstream. The speed of the highway patrol unit during
this operation was 40 km/h and the upstream traffic density was 150
vehicles/km. After passing the location of the maintenance works, the
highway patrol unit left the traffic stream, causing traffic speed to increase to
70 km/h and density to settle at 50 vehicles/km.
(i)
Develop a mathematical relationship between speed and density.
(ii)
Will the upstream traffic flow reach the maximum flow?
