We can quote some of the systems which are used to enhance the road traffic by minimizing traffic jams.

Example 1 - Closed Circuit TV (CCTV)
This system which uses the CCTV (Closed Circuit TV) is helpful in monitoring the road traffic, accidents and illegal activities and take appropriate actions accordingly.





Example 2 -Traffic Light Control System
These automated lights are positioned at road junctions. These lights are helpful in minimizing accidents by controlling the vehicle traffic and pedestrians.

Example 3 - Parking identification placard
This is an entrance pass which is stuck on the windshield of a vehicle. When the vehicle comes close to the gate of the parking space, the sensors read the placard and only open the gates if the vehicle is already pre-registered. This system also helps to avoid building up of traffic at the gates due to its quick processing  ability.
