3 © FGS Research- and Planning Group for town and traffic www.FGSBerlin.de Date: 10-09-2005www.FGSBerlin.de Michael Höppner 3 One remark before.... Driving and walking is very simple, everybody can do it, even without a special education

49 © FGS Research- and Planning Group for town and traffic www.FGSBerlin.de Date: 10-09-2005www.FGSBerlin.de Michael Höppner 49 Example #4:

50 © FGS Research- and Planning Group for town and traffic www.FGSBerlin.de Date: 10-09-2005www.FGSBerlin.de Michael Höppner 50 Example #4: wrong direction and no view

51 © FGS Research- and Planning Group for town and traffic www.FGSBerlin.de Date: 10-09-2005www.FGSBerlin.de Michael Höppner 51 What did we see? Statistical results don‘t lead directly to solutions -Only reviewing the locations will help

52 © FGS Research- and Planning Group for town and traffic www.FGSBerlin.de Date: 10-09-2005www.FGSBerlin.de Michael Höppner 52 What did we see? Problems of sight are risky.... -should be checked preventively, -best in an plan audit, -looking at more than the pure road side

53 © FGS Research- and Planning Group for town and traffic www.FGSBerlin.de Date: 10-09-2005www.FGSBerlin.de Michael Höppner 53 What did we see: Problems of sight may develop with time: -road inspections are needed as a standard maintenance -Building permission act and plan safety audit should join more

54 © FGS Research- and Planning Group for town and traffic www.FGSBerlin.de Date: 10-09-2005www.FGSBerlin.de Michael Höppner 54 What did we see? Road users develop there own „safety strategies“ -Road planners have to do their job... and remember that the road offers behavior setting to the user -If you can not avoid wrong behavior allow it and support it

55 © FGS Research- and Planning Group for town and traffic www.FGSBerlin.de Date: 10-09-2005www.FGSBerlin.de Michael Höppner 55 What did we see? Road functions might change with new neighbors -Road inspections have to realize the new situations and react -Redevelopment of roads is a permanent process, as part of normal maintenance

56 © FGS Research- and Planning Group for town and traffic www.FGSBerlin.de Date: 10-09-2005www.FGSBerlin.de Michael Höppner 56 Risk assessment in urban areas What are the safety problems in urban areas? -Car drivers at intersections -Cyclists at intersections -Pedestrians crossing the road -Driving to fast without sight -Behavior setting road design disregarding users sight and possibilities -traffic planning missing actual changes

57 © FGS Research- and Planning Group for town and traffic www.FGSBerlin.de Date: 10-09-2005www.FGSBerlin.de Michael Höppner 57 Risk assessment in urban areas Can we identify special areas? -Not really -Always need local approach -Traffic load determines number of conflicts

58 © FGS Research- and Planning Group for town and traffic www.FGSBerlin.de Date: 10-09-2005www.FGSBerlin.de Michael Höppner 58 Risk assessment in urban areas Do we know the backgrounds? -We can only look at obviously wrong or misleading road design -If we find some of these places we have done a lot -Good idea to consider personal “safety strategies”

59 © FGS Research- and Planning Group for town and traffic www.FGSBerlin.de Date: 10-09-2005www.FGSBerlin.de Michael Höppner 59 Risk assessment in urban areas Can we get active preventatively? -Yes, we can with standarised regular road inspections -Yes, we can with review of suspicous road sections
