4 cards from this section. Quick, good the night before a test.
Define flow in the context of traffic.
Think about how traffic is measured.
What is jam density?
Consider when traffic completely stops.
What parameter represents the volume of vehicles passing a point in a time?
Consider what traffic often counts.
True or False: Jam density is when vehicles can still move.
Think of what congestion looks like.
You observe that a freeway has a jam density of 400 vehicles/km and a free-flow speed of 80 km/h. What is the maximum flow on this freeway?
Use the maximum flow formula discussed in class.
If the maximum flow of a highway is 6000 vehicles/hour and jam density is 300 vehicles/km, what is the free-flow speed?
Rearrange the maximum flow equation to solve for free-flow speed.
