Traffic count data

Traffic count data is valuable for making road safety and temporary traffic management decisions, and scheduling renewal and resurfacing works.

Traffic count collection

Traffic count data is collected by Christchurch City Council for various key locations. This includes most controlled and signalised intersections and link roads.

Depending on the designation of the road or intersection, the counts will be done at periods of five-yearly, three-yearly, or two-yearly. Special counts are also done as one-off events. The most recent counts are shown on the maps.

For the traffic count data to be of any use, counts are not done during school or public holidays. Intersection counts are only done on Tuesdays, Wednesdays or Thursdays. This is to ensure that a more accurate representation of traffic data is collected.

Intersection counts are only done to cover the busy periods of the day. These are typically from 7am to 9am, 1pm to 2pm and 4pm to 6pm. These times may differ to ensure that the peak traffic hours are collected.

Link counts are taken over a 7 day period and averaged over the period.

State Highways

State Highways are operated by the New Zealand Transport Agency (NZTA) who conduct their own link traffic counts.

Council is not required to count the traffic on these roads, although we do have some count sites. If count data is available, the road will show in the list.

NZTA intersections are counted as part of Council intersection count programme.

Traffic count data terms of use

While all due care has been taken in the preparation and provision of this service, Christchurch City Council does not give any warranty that the information contained is accurate, and accepts no liability whatsoever for any loss or damage arising from the use of the data.

People using the traffic count data should apply and rely upon their own skill and judgement when using the information, and consider the consequences arising from its use. The data should not be used in isolation from other sources of advice and information.

Please note that traffic flow counts are variable due to various external factors, e.g. sensitivity of the equipment, counting methods used, congestion effects and seasonal variations. The traffic flow data is intended to be used as an indication of traffic volumes at counting sites.
