flow
When taking a count of traffic, it would be useful if the vehicles are classified into distinct types and the volume of each class is noted. This is known as ______.
classified volume counts
Since traffic can change over days of week, it is customary to take the survey for seven days consecutively. This will cover the effects of weekly holiday or weekly market. The duration of intersection volume counts can be restricted to ______ hours only.
peak
The Origin-Destination survey, abbreviated as O-D survey, is a frequent task of a Traffic Engineer. It seeks to fined ______ of traffic.
the origin and the destination
Speed is the rate of travel. It is measured in meters per second or kilometers per hour. Spot speed is instantaneous speed of a vehicle at a specified location When averaging out speed measurements, two types of mean speeds are met with: 1) Time mean speed 2) ______ mean speed.
