Traffic count data is valuable for making road safety and temporary traffic management decisions, and scheduling renewal and resurfacing works.
Vehicle traffic count data is collected by Christchurch City Council for various key locations.
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.
Cyclist trip count data is collected by Christchurch City Council for various key locations.
The number of count locations has incrementally been increased since the first counter instalment in 2016. As of December 2020, there are 26 counters located throughout the city and reported here.
The key locations chosen to count at have been selected to represent the cycle usage on the transport network both on and away from major cycle routes. The locations are selected to capture different usage types, such as educational, commuter and/or recreational trips.
Some count locations capture only one direction of cycling, however, the overall mix of locations captured in, out and orbital city flows.
This equipment counts the number of cycle movements all day, every day. The data collected is used for a variety of reasons including:

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