Part 4 HD Traffic real time traffic information
In the previous articles we have seen how the geometry of the map is created, then the attributes for each road segment have been added. With IQ Routes each road segment was assigned a 'real speed' based on historic average speeds in 5 minute intervals. Now with HD Traffic we can see how these IQ Route average speeds can be dynamically updated in near real time with actual current road speeds.
Please post any comments in the main article thread here. _________________ Mike Barrett
