State-by-state, traffic cameras are ubiquitous in the US and Canada, and now they’re starting to pop up in India.

The number of cameras has exploded since 2011, when India introduced its first traffic cameras.

There are more than 500 in the country, mostly in major cities, but some are in rural areas and towns.

State-by the numbersThe total number of traffic cameras in India is about 5,500.

Here are the most common states where traffic cameras operate:• Karnataka, where more than 30,000 cameras are installed • Maharashtra, where 7,000 traffic cameras exist • Tamil Nadu, where 4,000, plus some mobile units that are being installed in rural locations, are among the most popular states for cameras.

There are more cameras in the state of Maharashtra than in any other state.

New Delhi has more than 1,300 cameras in its capital, but about 20 of them are in residential areas.

Some other states, including Punjab and Haryana, have more than 100, while the rest have less than 100.

The biggest cities, including New Delhi, are home to a large number of such cameras.

Traffic cameras are expensive.

But the cameras can make a huge difference in reducing accidents.

India has an average traffic speed of just 16kmph, compared with the US’s 32.7kmph.

That’s due to a number of factors, including the lack of traffic signals and parking regulations, and the fact that roads are narrow, with traffic moving slowly and carefully.

They make it easier for drivers to spot other vehicles on the road.

They also reduce the number of people involved in accidents, because cameras catch the attention of other drivers, which in turn increases the speed of traffic.

As the number and type of traffic camera systems increase, more states are going to have more.

And with that, the number will keep on growing.
