1 Forecasting, planning and monitoring of traffic in Verona by integration of CUBE (simulation model) and MISTIC (integrated traffic supervisor) Arch. Bruno Pezzuto Traffic Control Center

2 City of Verona inhabitants (2012, 24 th sept)

3 Mobility in Verona (2010) vehicles 1,25 average vehicles/head 1,2 average of displacements per day per person displacements/day 20 average time for any displacement

4 ITS for Verona The city of Verona uses for many years the CUBE software for planning and study of urban traffic. In 2007 was realized the integrated system for mobility management whose strength is represented by the urban traffic control which has obtained sensitive improvements in urban roads.

In 2007 was realized the integrated system for mobility management whose
