The SAMPERS project - an over view By Gunnar Johansson Sveder Transek AB Postal address: Solna Torg 3, S Solna, Sweden Tel: , Fax: web:
28 April Background 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
28 April The old national traffic forecast system National road network data bank Public transport (train, bus, air ) Maps EMME/2 GIS FREDRIK regional trips Socio-economic data IC/3 long distance Car owner ship EVA CBA - assessment
28 April The project Contract April 1998 New traffic demand models –Current data National travel survey ( ) 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
28 April Data assembling Quality control Trips construction Estimation Client approval Model implementation Validation (Survey, Elasticity) Validation (Traffic counts) The project process
