3 cards from this section. Quick, good the night before a test.
Define jam density.
Consider what happens when traffic is heavily congested.
What does free-flow speed represent?
Think about how fast you could drive in ideal conditions.
What is jam density?
Think about the point at which traffic becomes too congested.
True or False: Free-flow speed is the speed at which congestion begins.
Remember what happens in ideal conditions versus congested conditions.
A highway has a jam density of 150 vehicles/km and a free-flow speed of 90 km/h. Calculate the maximum flow.
Substitute your known values into the maximum flow formula.
If the maximum flow on a given section of road is measured at 5000 vehicles/hour, what would be the jam density if the free-flow speed is 70 km/h?
Make sure to work step by step through the rearrangement.
