A large Crown Entity wanted to gain insights into the root causes behind high death and serious incidents (DSI) rates occurring in a specific region of New Zealand. Statistical analysis was sought to confirm whether there was a relationship between certain factors (transport network design and socio-economic) and DSI rates.
Harmonic constructed the data models necessary to assess whether anecdotal descriptions of DSI rates and causes were evidenced in data. These models utilised various data sources including crash data and The Department of Statistics’ Integrated Data Infrastructure (IDI).
This analysis was then used to develop a highly visual and interactive crash analytics dashboard that could be used by a wide range of stakeholders. Each visual and interactive feature was carefully selected to improve the assimilation of crash analytics outputs.
Key features of the dashboard include a comparator view allowing different regions’ crash data to be compared, a word cloud identifying the causes of crashes for a selected area(s), and a geospatial view of crash counts and causes, covering the entire country.
