a traffic facility during an hour.
What is this?
Demand
Volume
Flow
v/c Ratio
Given that a 6-lane highway has 3 lanes per direction.
If the flow per lane is 1800 veh/h/ln in the eastbound direction.
What is the flow for that direction?
5400 veh/h
3600 veh/h
2400 veh/h
1800 veh/h
Assume that headways between consecutive vehicles in a lane are uniform. If the time headway is 6 seconds, what is flow rate?
1800 veh/h/ln
1200 veh/h/ln
900 veh/h/ln
600 veh/h/ln
Given that the jam density of a highway segment is 60 veh/km/ln and
Free-Flow Speed (FFS) is 100 km/h.
If the average speed of vehicles on the segment (u) is 55 km/h.
What is the flow condition?
Congested Flow
Uncongested Flow

and converted to vehicles per hour.
What is this?
Flow

Either will do.
Neither of them.
For a low flow condition, the distribution of the arrival rate is ...
Binomial
