INTRODUCTION 1/2

• Relevant National Research Program financed by
  Italian Research Ministry Non conventional
  transit systems fields of application and
  feasibility analysis
• Research teams
• University of Rome Tor Vergata
• University of Calabria (Cosenza)
• University Mediterranea of Reggio Calabria
• University of Roma Tre

Phases of research 1) Classification of transit
systems - Classification criteria - Analysis
and classification of transit systems - Analysis
and identification of applicability contexts 2)
Feasibility studies of advanced transit systems
- Methodological and simulation issues-
Application to 4 test-sites 3) Results

Strategic urban pole
Link by new transit systems

• Buses
• Tramways

- high performances- medium-short distances (lt 5
Km)- medium-low line capacity (lt 10.000 spaces/h
per dir.)

Light automated guideway transit systems

• AGT light metros
• Monorails
• Funiculars
• Ropeways

- Global automation - Light facilities - Reserved
and exclusive lanes - Low environmental impact
