Variable-message signs, or VMS, are electronic equipment which
may display different traffic messages consistent with the
requirements of a selected road. Permanent VMS displays are
mounted on large sign structures overhead or alongside the road.
These devices are often placed on urban freeways which have
traffic problems. Portable CMS (PVMS) panels are usually
mounted on trailers, although some could also be carried by
trucks. they're often utilized in work zones or other events that
A traffic signal , also referred to as traffic light , stop light, stop-
and-go lights, may be a device positioned at a road intersection,
zebra crossing , or other location so as to point when it's safe to
drive, ride, or walk employing a universal code (and a particular
sequence, for that are colors blind).Nowadays, a red light meant
traffic altogether directions had to prevent . A traffic light meant
cross-towntraffic would need to slow and a green light would to

Traffic Lights are wont to control the vehicle traffic . within the era
, everyone has differing types of vehicles leading to rise to the
numbers of vehicles. That’s why traffic lights are mandatory to
avoid the traffic jams and accidents. There are three lights within
the traffic light , having different message for the drivers. Red light
(upper one) asks the driving force to yield at the intersection,
green light (last one) gives the driving force free
drive through the intersection ...Traffic flow radar uses a "side-fire"
technique to seem across all traffic lanes during a narrow band to
count the amount of passing vehicles and estimate traffic density.
For stopped vehicle detection (SVD) and automatic incident
detection, 360 degree radar systems are used as they scan all
lanes along large stretches of road. Radar is reported to possess
better performance over longer ranges than other technologies.
