Sustainable safety: Designing streets the Dutch way

  1. 1. Sustainable safety: designing streets the Dutch way
  2. 2. What is sustainable safety? • Intrinsic safety or lasting safety: safety by design not safety by regulation • Streets become places where people aren’t pushed to the periphery by cars
  3. 3. Sustainable safety in the Netherlands • Idea introduced in early 1990s as a way of tackling road deaths and injury • “The central issue is that people, even if they are highly motivated to behave safely while using the road, make errors that may result in crashes.” Advancing Sustainable Safety, SWOV, 2005 • “Sustainable Safety aims to ensure that road safety depends as little as possible on individual road user decisions. The responsibility for safe road use should not be placed solely on the shoulders of road users but also on those who are responsible for the design and operation of the various elements of the traffic system.” Advancing Sustainable Safety, SWOV, 2005
  4. 4. Who benefits? • Everyone! • Vehicles and people with very different speeds and masses are not expected to share the same space • Urban environment becomes more people- friendly.
  5. 5. Five principles of sustainable safety • Functionality • Homogeneity • Predictability • Forgivingness • State awareness
  6. 6. Functionality • All Dutch roads are classified according to their function and fall into three categories: access, distributor and through roads • These streets have a mono-functional design which is appropriate for their purpose
  7. 7. Functionality • Idea comes from Buchanan’s 1963 report Traffic in Towns Swav.nl taken from Traffic in Towns
  8. 8. Through roads • Fast roads carrying high volumes of traffic • Motorways, trunk roads, bypasses • Completely separate facilities for cycling and walking and usually at a distance from the highway
  9. 9. Distributor roads • These connect the access roads to the through roads • They carry more traffic than access streets so a greater degree of separation of modes is necessary
  10. 10. Access roads • These are typically residential streets • They are not through roads and therefore carry very low volumes of traffic • They are designed to slow down traffic
  11. 11. Homogeneity • Difference between mass, speed and direction of travel of vehicles using same space is minimized
  12. 12. Predictability • Roads made predictable by using consistent designs • Street design sets expectations about how the space is used through use of materials and colour, and consistent design of crossings
  13. 13. Forgivingness • Anticipating mistakes and accepting that humans are fallible • Making sure that mistakes aren’t fatal
  14. 14. State awareness • Education becomes an essential complement to sustainably safe road design • NOT a replacement for good design
  15. 15. Can we do this here? Yes!
