From EMME to DYNAMEQ in the city of MALMÖ

THE COMPANY Founded in early 2011 Currently located in Stockholm, Gothenburg and Malmö Small company (currently 4 employees) but with many years of experience AREAS OF BUSINESS Supply & demandmodelling and simulation from national strategic levels to separate intersections Traffic planning (Road, Public transport, Bicycle and pedestrians) Cost-Benefit analysis Implementation & developement of models for traffic analysis Analysis and studys regarding accessibilty, parking, emission etc. Evaluations of infrastructural investments MODELS (SELECTION) Emme Sampers/Samkalk Dynameq Vissim ArcGIS

BACKGROUND

City of Malmö -Founded the year 1250, became part of Sweden in About inhabitants -30 % of population represent 170 different countries. -University with students. -Every day more than 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 About inhabitants -30 % of population represent 170 different countries. -University with students. -Every day more than 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

EMME Network traveltimes with and without the use of tpf in EMME OD-relations within the City of Malmö

EMME Route choice Without and With Tpf (uncalibrated demand from Sampers) No Tpf (185 counts) Tpf (185 counts) Y = x; R2 = 0.76 Y = x; R2 = 0.82

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
