BACKGROUND

City of Malmö -Founded the year 1250, became part of Sweden in 1658. -About 300 000 inhabitants -30 % of population represent 170 different countries. -University with 20 000 students. -Every day more than 70 000 people make the 30 minute trip between Malmö and Copenhagen using the Öresund bridge. -Part of the transnational region of Öresund with 3.5 million inhabitants -Expected increase of population with 33 % in the next 20 years City of Malmö -Founded the year 1250, became part of Sweden in 1658. -About 300 000 inhabitants -30 % of population represent 170 different countries. -University with 20 000 students. -Every day more than 70 000 people make the 30 minute trip between Malmö and Copenhagen using the Öresund bridge. -Part of the transnational region of Öresund with 3.5 million inhabitants -Expected increase of population with 33 % in the next 20 years BACKGROUND

The city of Malmö is currently going through massive changes in its infrastructural design New areas developed for living and working - the city prepares for a 33 % increase of population next 20 years To meet the expected increase of travel, the city is planning different measures in the transport infrastructural design, such as tram, fastlanes for busses, better bike facilitys, motorway interchanges etc Historically the city of Malmö have used static assignment models, such as Emme s a planning tool for different measures in the road infrastructure on a global level and microsimulation on a local level Due to the expected increase of travel both within the city and commuting to- and from the growing region of Öresund the need of a planning tool with better possibilities to measure congestion has grown Growing interest in what way different measures will affect route choices, queue lengths, travel times etc. both in shorter time horizons and in more strategic time horizons (20+ years) BACKGROUND

EMME vs DYNAMEQ Network traveltimes during AM peak hour: Dynameq versus EMME OD-relations within the City of Malmö Ratio Dynameq/Emme
18
EMME Network traveltimes with and without the use of tpf in EMME OD-relations within the City of Malmö
19
EMME Route choice Without and With Tpf (uncalibrated demand from Sampers) No Tpf (185 counts) Tpf (185 counts) Y = -426+1.16x; R2 = 0.76 Y = 280+0.98x; R2 = 0.82
28
CONCLUSIONS Network: ArcGIS powerful tool to edit large networks Demand: Need for more detailed data (time + centroids) DTA: Peak hours and 24-hours - different aims and challenges EMME v.s. DYNAMEQ: significant differences in traveltimes raises questions about the validity of demand modelling and cost- benefit analyses based on EMME in congested networks? EMME: The use of tpf (not default in Sweden) affects route choice and traveltimes in a significant way From EMME to DYNAMEQ
