The investment in the transport system, whether carried out at the infrastructure or operational level, implies a careful assessment of the associated costs and benefits not only from the service provider's and users’ perspective, but also for society (considering all the externalities associated).

If, up until recently, the economic evaluation was oriented to evaluate large projects, it is now clear that there are advantages in evaluating all the projects, to clarify which benefits are expected to be achieved, ensuring "the best value for money".

TIS's integrated vision enables organizations to understand the business risks and opportunities, enabling informed decision-making.

TIS has a large experience in developing various demand studies and studies on the calculation of social and environmental benefits to assess the expansion of the Lisbon and Porto Metro networks. At a road infrastructure context, TIS has also been one of the privileged partners of one of the main Portuguese road operators.

More recently, aimed at supporting tendering processes for public road transport networks, TIS has developed the Economic and Financial Feasibility Study required for this process.
