Question
A data collection study found a linear speed - density relationship for a highway as follows u/65 +k/120 =1
1-Write down the speed - density ( given ) , flow - density and flow - speed models , and plot their relationships
2-raffic study has shown that the time headways between successive vehicles on this highway are exponentially distributed and that 30% of the headways between vehicles are 4 seconds or greater. Apply the traffic models derived in the question a), compute speeds and densities corresponding to this flow.
