Long tradition of cost-benefit analysis of investment projects Long tradition of modelling - from 4-step to disaggregate systems SAMPLAN, extensive co-operation between agencies responsible for road, rail, air, sea National transportation plan, investment plan, transportation policy: maintenance, taxation, road pricing, technical development, regulations Evaluation of alternative scenarios the society efficiency, environment, safety, regional balance Detailed cost-benefit analysis Background
National road network data bank Public transport (train, bus, air ) Maps EMME/2 GIS EVA CBA - assessment IC/3 long distance FREDRIK regional trips Socio-economic data Car owner ship The old national traffic forecast system
Contract April 1998 New traffic demand models Current data National travel survey (1994-1997) SP-survey (time of day) Fehmarn Belt, Öresund All trips Regional National long distance International Time of day modelling Long distance public transport trips Secondary destination Regional trips Computer System EMME/2 Plenty of forecast parameters Integrated into one single user-friendly system Car ownership Demand models Impact calculation Cost benefit analysis Accessibility calculation Flexibility to output data Validation Delivery, spring and autumn 1999 The project
