Assignment (traffic)

The allocation of traffic volumes to routes.


A road with two or more intersections.


Time interval in an arterial progressive system during which vehicles can travel unimpeded.


A device which controls the sequence and duration of indications displayed by traffic signals.


The establishment of a definite timing relationship between adjacent traffic signals.

Cycle time

The time required for one complete sequence of signal indications.

Delay (traffic)

The time lost by vehicle(s) due to traffic interference or control devices.

Detector (traffic)

A device to detect the presence or passage of a vehicle in the roadway.

Flow (traffic)

The rate at which vehicles cross a given line on the road; the number of vehicles per unit of time.


The time interval between successive vehicle crossings of a given line on the road.

Intelligent transportation system

The addition of information and communications technology to enhance...
