Pedestrian Crossing - Safety

Safety

The safety of unsignalled pedestrian or zebra crossings is somewhat contested in traffic engineering circles. This is because pedestrians sometimes use the crossings without looking to see that cars have seen them and are actually stopping.

Research undertaken in New Zealand showed that a zebra crossing without other safety features on average increases pedestrian crashes by 28% compared to a location without crossings. However, if combined with (placed on top of) a speed table, zebra crossings were found to reduce pedestrian crashes by 80%.

A five-year U.S. study of 1000 marked crosswalks and 1000 unmarked comparison sites found that on most roads, the difference in safety performance of marked and unmarked crossings is not statistically significant, unless additional safety features are used. On multilane roads carrying over 12,000 vehicles per day, a marked crosswalk is likely to have worse safety performance than an otherwise similar unmarked location, unless safety features such as raised median refuges or pedestrian beacons are also installed. On multilane roads carrying over 15,000 vehicles per day, a marked crosswalk is likely to have worse safety performance than an unmarked location, even if raised median refuges are provided. The marking pattern had no significant effect on safety. This study only included locations where vehicle traffic was not controlled by a signal or stop sign.

The Queensland government no longer builds pedestrian crossings due to safety concerns, preferring pedestrian refuges instead.
