I have been a fan of open source, and I found a great little iphone APP that takes two data sets and adds value. This app shows you where the traffic jams are located in Hong Kong so you can pick the best route to your destination, get your FREE app at iTunes
click on an image to enlarge………. the red overlay indicates heavy traffic, green overlay indicates normal traffic, it is real time and that simple.
