TSS’s maintenance programme, called Software Upgrade Subscription (SUS), enables Aimsun users to receive major software upgrades for a flat annual fee. The first year’s SUS is included, free of charge, with every new licence bought.

With the frequency of major releases averaging one per year, SUS not only spreads your upgrade payment but also represents excellent value for money compared to purchasing individual upgrades. The upgrade process is seamless, new versions are backwards compatible and you can even run the new and old versions side-by-side.
