Basically takes your dispatch and "enhances" it further. Loop boundaries are no more. Pickups are fair game. It will attempt to dispatch ground stops where there is a random air stop. Problem is, it doesn't assign it properly in the RDO so usually the air ends up in the 1000 shelf, while that ground stop is in your 7000s.
In addition it will also move sequences with no stops assigned to it just in case something comes in unforecasted. To top it all off, it takes about 40 minutes for the roads tool to do its thing. And then the PDS needs to double check what it did to make sure nothing is goofy. So you're looking at needing to have your dispatch plan done at least an hour prior to the preload.
Once it's done, you'll get an excel spreadsheet that tells you what sequences and addresses it moved. So unless you know every route in and out,, it makes it hard to quickly double check. No map overlay of the routes to give you a quick glance of before and after.. Your PDS will be really happy about having to come in even earlier depending on what building you work at.
If you have any pickup times that are wrong, LBT or anything else that could create wait time, it will attempt to eliminate that and move random stops. Best thing you can do is make sure you plans are pristine to get it to make as few of moves as possible.
There is an exclusion tool that you'll get so you will have the ability to select certain routes not to get looked at, but just like with everything, if you exclude too much, you'll hit a report. The one nice thing is planned bulk stops (assigned to a shelf or floor location) won't get touched.
I love it.
