19/20CONCLUSIONS

Microsimulation30-second periods analysis

Different scenariosContribution to the discussion on the use of microsimulation models on interchanges analysesNext steps...More consistent and systematic approach (regarding to the consideration of the time variable in the performance analysis of the LOS)

Build a richer database (in order to apply the methodology to other interchanges)

Progressively eliminate the microsimulation tools limitations
