Hi Hüseyin:

In the UK a valuable source of traffic density values is: https://www.dft.gov.uk/traffic-counts/ and http://bettertransportmaps.org.uk/map-traffic-2005-2013.html

Just in case you consider the possibility of analysing cities there.

At international level, we have worked with TomTom data, but the datasets are not free.

Best,

Gustavo

Hi Gustavo,

Thanks for your answer, but we need how we can read level of traffic from map and we want to use the value for calculation of air pollution over a city. distribution
