Add color codes to Map view of alternative routes.
When you calculate alternative routes, you get a List view and a Map view. On List view you can see approximately how congested the routes are, but you don't see where exactly are the congestions. In current Map view, you don't get any info about traffic jams. It would be very useful to have color coded map of the selected route in Map view, maybe also small dots to shows warnings, accidents and other infos sent in by the users.
