The HIGH-TOOL model is an open source, high-level strategic assessment model for use by EU policy makers and policy analysts to assess economic, social and environmental impacts of transport policy measures. The model has two purposes. It can be applied to strategic assessment of transport policy options, and to support identification of policy options for further analyses by more detailed assessment instruments.
The HIGH-TOOL model is introduced successively during the project in order to facilitate the participation of users. Its development has been divided into three stages: prototype, pre-final version and final version.
The prototype version, completed in 2014 fulfilled following objectives: to establish a concrete basis for collecting comments and recommendations from the future users, and to allow the HIGH-TOOL partners to gain experiences in the modular tool development.
The pre-final version is a Java-based tool, running at NUTS-2 level, and allows the analysis of a wider field of transport policies.
After an extensive testing and validation phase, the final model version was developed.
The model evolution process has been carried out under the involvement of the future users and is accompanied by a Scientific Advisory Board, made up of distinguished experts that represent model users and model developers.
Output indicators of the model are largely based on policy targets of the White Paper 2011, the Roadmap for moving to a low-carbon economy in 2050 and the requirements of the European Commissionís Impact Assessment Guidelines. The HIGH-TOOL model will be calibrated against official statistics, and consistency between the model and the EU Reference Scenario 2013 will be ensured. The HIGH-TOOL database is closely linked to ETISplus.
The report on several methodological aspects of the final version of the HIGH-TOOL model is online available. The report describes the modelling methodologies underlying each individual module, and presents the relevant equations. Furthermore, in order to provide a basis for model validation, the deliverable contains an extensive study on elasticities. Finally, the report covers the identification of policy variables of Transport Policy Measures and their upper and lower bounds.
