The research project IPTOP aimed at developing new methods for planning, designing, controlling and optimising Danish public transport systems. The benefits for the passengers would be short travelling time and better service. Aditionally the transport operators would gain economically. All together the expectations were to gain substantial societal and economic benefits compared to the overall investment.

IPTOP focused on the use of recent advances in the field of analytics (databases, analysis tools) and new traveller data sources (due to new fare collection technologies). These advances provided an
opportunity for a completely fresh and new application of mathematical optimisation at a very large scale.

The project was funded by the Innovation Fund Denmark for a period of 5 years from 2015-2019.
