Quantm is a software package that is used to optimise the routes of roads and railways. This was hitherto a tedious and laborious task as huge amounts of data are involved and the number of options is large as well. The Quantm software takes all the data and constraints and generates a prioritised list of good options that the user can choose between.

Quantm was originally developed by CSIRO of Australia, and is now owned by Trimble Navigation and developed at Trimble Planning Solutions in Melbourne, Australia.
