Model uncertainties

Models are by definition affected by uncertainties (in input data, input parameters, scenario definitions, etc.). Have the model uncertainties been quantified? Are uncertainties accounted for in your simulations?

yes
The uncertainties have been quantified by several stakeholders including heavy duty vehicle manufacturers.

    Sensitivity analysis

    Sensitivity analysis helps identifying the uncertain inputs mostly responsible for the uncertainty in the model responses. Has the model undergone sensitivity analysis?

    yes
    Yes the JRC has made a first sensitivity analysis, the findings are currently under publication.

      Have model results been published in peer-reviewed articles?

      yes
      It undergoes continuous review by industrial stakeholders who use it for certification purposes and independently by the JRC.

        Has the model formally undergone scientific review by a panel of international experts?

        Please note that this does not refer to the cases when model results were validated by stakeholders.

        no

          Model validation

          Has model validation been done? Have model predictions been confronted with observed data (ex-post)?

          yes
          Three reports have been published to date on the topic by the JRC. Validation has been done by some member states and by industrial stakeholders.

            Transparency

            To what extent do input data come from publicly available sources?

            This may include sources accessible upon subscription and/or payment

            Based on both publicly available and restricted-access sources

            Is the full model database as such available to external users?

            Whether or not it implies a specific procedure or a fee

            no
            There is no underlying database, the input is vehicle specific and derived during the certification process.

              Have model results been presented in publicly available reports?

              Note this excludes IA reports.

              yes

              Have output datasets been made publicly available?

              Note this could also imply a specific procedure or a fee.

              no
              Depends on who is using the model. As JRC we draft reports and papers on the simulations we run with VECTO.

                Is there any user friendly interface presenting model results that is accessible to the public?

                For instance: Dashboard, interactive interfaces...

                no

                  Has the model been documented in a publicly available dedicated report or a manual?

                  Note this excludes IA reports.

                  yes

                  Is there a dedicated public website where information about the model is provided?

                  yes

                  Is the model code open-source?

                  yes
                  The source code, the users manual and the technical annex regarding VECTO are public by law.

                  Can the code be accessed upon request?

                  not applicable
