I drive the same busy highway every morning (I-64) here in the Hampton Roads of Virginia. A major section of it is under construction. Instead of passengers and/or drivers taking their eyes off the road to manually enter moderate/heavy/standstill traffic, it would be nice for Waze to automatically detect it and publish it to the map since there are enough people using Waze in this area. I'm sure an algorithm can be written that can detect Wazers within a 1-5 mile radius that are traveling at a particular speed and be able to automatically display the 'traffic speed' for a particular area instead of manually doing it. It will help fight traffic especially for those Wazers that aren't comfortable using their device while driving. It's kind of like having hundreds of thousands of sensors to automatically tell you the current driving speeds without having Wazers to manually do it. It would be more accurate for guidance, safer for the Wazers and ultimately better for the environment because of less traffic.
