Traffic flow at major junctions would be much easier and better soon, as Visakhapatnam will soon be equipped with Vehicle Actuated Controlled (VAC) system at major traffic signal junctions, as a part of Smart City Project. This system will monitor and flash lights (Green, Red and Orange), based on the flow of vehicles. At present, the traffic signals in the city works on Fixed Time (FT) mode, wherein irrespective of the volume of vehicles in a lane, the traffic lights change after a fixed time set by the traffic police. Based on the traffic flow at a particular junction, the police would increase or reduce the time frame, in phases through the day.

50 junctions

According to officials, the L&T company, which is handling this project, as part of the smart city projects, has already set up such system at 25 traffic signal points out of total 50, on a trial basis. Satyam Junction, Thatichetlapalem junction, NAD Junction, Hanumanthuwaka Junction and many parts on NH-16, apart from Tycoon Hotel junction and few others inside city limits are included.

Explaining the functioning of the VAC system, Executive Engineer (EE-Smart Cities) Greater Visakhapatnam Municipal Corporation (GVMC) V Sudhakar saidm “The programming of VAC is designed in such a way the CCTV cameras, which are embedded in the system will measure the length of traffic in all points and decide which side is to be given green signal and which side needs a red. It will keep on calculating the traffic length and adjust the timing.” Mr. Sudhakar also added that all these traffic signal junctions are connected to Command Control Centre (CCC) at GVMC.

‘Not all the time’

Additional Deputy Commissioner of Police (ADCP-Traffic) M. Ramesh Kumar said that even though VAC systems comes in handy, there will be a traffic police at all junctions, as there could be situations like passing of ambulances, VIP visits and other emergencies. “During emergencies and green channels, traffic police will change it into manual mode, while during normal times, it would be kept in VAC mode. At present, our traffic police are being trained by L&T personnel on how to operate this system. After training, we will use it to the fullest,” the ADCP added.
