Development of project

• Start 2008

• EMM e.V. = European Metropolitan Area Munich Marketing and debating platform with different thematic working groups: education, culture, economy, environment, mobility

• Pilot project „Accessibiliy Atlas“– First step: regional database, published 2010– Currently:

o cooperation on county level to develop the local level and applications in strategic land-use and transport planning

o „Stress-tests“ for sustainable mobility


Stand heute - Ergebnisse


Stand heute - Ergebnisse- Spatial resolution: municipalities

consistent data availability

- Development of submodels for local analyses

- OpenStreetMap network data

- CORINE Land Cover Land Use Datao disaggregation of structural datao speeds in built-up areas

- Public Transport timetables from authorities or publications

- Webtool version (should be launched one of these days…)


Stress-test for sustainable mobility

Two interesting study regions: - European Metropolitan Region

of Munich - Metropolitan Region Lyon

Two teams: - Department of urban structure and transport planning / TUM - Laboratory of Transport Economics / LET

Opportunities of collaboration: - PhD Summer school 2009 (Frauenchiemsee) with BFHZ - Joint proposal to WCTR … NECTAR … PREDIT


Stress tests - Research questions• Which locations (e.g. in terms of economics) and which

groups of society are mostly in danger to suffer from social exclusion in the face of the scenarios?

• How are different transport modes affected? Are existing public transport systems able to step into the breach? If not, which investments are necessary to prepare public transport for possible new challenges?

• Which new opportunities and challenges will arise for electric mobility as well as neighbourhood mobility?

• How can land-use patterns (jobs, shops, homes ...) be

relocated to avoid severe accessibility drops?


Three dimensions of vulnerability

Exposure is the contact between system and stress

Sensitivity is the degree to which sth./so. is affected by exposure to stress

Resilience is the ability of sth./so. to absorb stresses wo. changes in its fundamental structure or function

(Kaspersons et al. 2006)


Suggestions for indicators• Exposure:

- Vehicle-km / household- (Commuting distances)- Cars per household- …

• Sensitivity:- Unemployment rate- Income/taxes

• Resilience:- Accessibility- Age- Family situation


Exposure: Car ownership


Sensitivity: Unemployment rate


Sensitivity: Monthly income


Resilience: Accessibility for public transport


Resilience: Accessibility for PC/PT
