Wellington Traffic & Mobility Explorer
Insights
Data stories from Wellington's transport sensor network. Each insight is a self-contained analysis connecting WCC Vivacity counts to weather, fuel prices, and public transport data.

About this data
Sensor normalisation. Wellington's sensor network grew from ~113 to ~383 active sites between Jan 2024 and Apr 2026. All city-wide totals — cyclists, cars, and freight — are divided by the number of active sensors in each time period so that new sensors entering the network don't appear as real traffic growth.
Incomplete months. All monthly charts exclude the current calendar month. A part-month would appear as a steep drop at the right-hand edge, which looks like a trend but is just missing data.
Sensor overlap. Adjacent countlines may count the same vehicle more than once — this is inherent to how the sensor network is laid out, not a data error. Counts are best read as an index of relative change rather than absolute volumes. Infrastructure comparisons (before/after) are unaffected since the same sensors are used in both periods.
