* Changed 'seasonal closures' avoidance option to 'date and time closures'. MapSource will now route over roads that have time-of-day and seasonal closures if this avoidance option is not checked.
Interesting. It's nice to at least have the option to disable and enable routing via time-of-day and seasonal closures. Ideally, GPS software should be aware of time-of-day, day-of week, and season, and routing should be adjusted accordingly. But I have not yet seen a product that deals with time-of-day traffic restrictions based on actual time-of-day. They all simply avoid routing through there at all times, even if the restriction may be only for between the hours of 7 am to 9 am, and even if it happens to be a completely different time of day.
I realize this is not a trivial feature to implement, and there are several variables to consider.
