I want to build an electronics project, a big portrait printed map where the main roads are replaced with LED coloring from green to dark red depending on the traffic, the problem is that I cant seems to get google traffic layer as data " I mean each pint and traffic for it" Google api give you estimate it time between 2 points . While I am looking for traffic in certain point . My last resort is to screen capture the map and doing canvas and image processing and determine color of the road at every point. The problem this is not good and will cause problem in the future .
Any one can help in Idea how to tackle this problem ?
