The speed limit on State Highway 1, between Warkworth and Puhoi, changed from 100kph to 80kph on June 14 last year.
In response to an enquiry from a Mahurangi Matters reader who asked, “Have the number of crashes on the road decreased as a result?” (see letter) Waka Kotahi-NZ Transport Agency provided the table right.
The table provides data from the Waka Kotahi Crash Analysis System, which is updated once a Traffic Crash Report (TCR) is received from NZ Police sometime after the crash. It reflects accidents on SH1 between Puhoi Road and Hill Street.
However, the agency says that the data for last year and this year is incomplete as it can take several months for some non-fatal crashes to be entered into the system.
Due to the nature of non-fatal crashes it is believed that these are under-reported, with the level of under-reporting decreasing with the severity of the crash.
The amount of traffic on the roads during level four lockdowns was greatly reduced, which consequently reduced the number of road crashes.
Road movements under the Orange and Red levels of the Traffic Light system would also be reduced due to the restrictions in place, so data from these periods will not align with previous trends.
