This tool allows you to import a route with stoptimes and depart times.
Each of the stops has a separate column to specify stop time in minutes.
This has been tested with MapPoint 2011 North America, but could easily be modified to work in any version of MapPoint.
Work on this was originally started for a question in this forum here:
Import a Route with Stoptimes
Depending on your needs if you are working with routing in MapPoint, you should also take a look at RouteWriter / RouteReader.
RouteWriter: Export Microsoft® MapPoint® Route WayPoints to Excel®
Hope this helps someone. Any suggestions or modification requests are welcome, Happy Mapping!
