SASI Model

The regional economic model SASI was developed by the partners of S&W in co-operation with the Technical University of Vienna in the EU project SASI (Spatial and Socio-economic Impacts of Transport Investments and Transport System Improvements). The model has since been applied in several EU projects, such as IASON (Integrated Appraisal of Spatial Economic and Network Effects of Transport Investments and Policies),  ESPON 2.1.1 (Territorial Impacts of EU Transport and TEN Policy) of the European Spatial Planning Observation Network (ESPON), the Interreg-IIIb project AlpenCorS (Alpen Corridor South) and the projects STEPs (Scenarios for the Transport System and Energy Supply and their Potential Effects) and ESPON ET2050 (Territorial Scenarios and Visions for Europe).

The SASI model

The SASI model has been continuously further developed in the course of the projects. Most recent developments include the modelling of generative effects of transport infrastructure investments and the inclusion of the West Balkan countries and Belarus and Russia into the study area. The SASI model is described in:
