Main components of raised crossing arrangement site 7 in Israel.

  • 1. – a raised crosswalk
  • 2. – a circular speed hump before the crosswalk
  • 3. – traffic signs and amber flashing light

Yielding at Swedish sites

Pedestrians were more often given way by the first driver in the near lane when the distance between the crossing and the speed cushion is longer: 50% at longer distances compared with 40% at shorter (p < 0.05)

Israeli results

Mean speed and the 85-percentile were both reduced by 20-30 km/h The share of vehicles yielding to pedestrians increased from 80% to 96-98%, in the near lane, and from 62-63% to 98-100%, in the far lane.

Traffic environment for children: max 20 km/h

  • If the goal is to eliminate serious injury accidents

30 km/h might not be a sufficiently low speed Höskuldur (2015)

  • Children 7 to 12 should not cross streets at

location where vehicle speeds exceed 15-20 km/h Johansson & Leden (2010)

Actions taken at the crosswalk with most pedestrians injuries in the city. Kaivokatu, Helsinki, Finland

1.30 km/h speed limit marked with signs 2.Automatic speed enforcement with a camera 3.Road markings in the carriageway 4.Advanced stoplines with ten meters
