We have work with +Vecteezy and publish this set of 70 flat design transport/traffic-themed icons. Personally I love this set very much and think it would be a good addition to your collection – especially if you are making traffics or vehicle related infographics recently.
Icons come in .psd and .ai files, download size at 3.05MB.
