Questions, answered briefly

Which Christchurch intersection has the most crashes?

Marshland Road & Prestons Road, 184 police reports pinned to it.

How many intersections are in the crash record?

8,212 road pairings, every pair of roads the Crash Analysis System (CAS) locates a Christchurch crash by.

Where do the numbers come from?

NZTA’s Crash Analysis System: crashes police wrote up, filtered to Christchurch City. Damage-only crashes sit undercounted beneath it, so the true figure is higher.

Does a pairing’s pin mean the crash was in the intersection?

Not exactly, the CAS record locates a crash by the nearest pair of roads, so the pin is the nearest crossing, not proof the crash happened inside the intersection box.
