Changhua City road accident hotspots and casualties
From 2024/01 to 2026/08, Changhua City recorded 14,760 casualty road accidents, 37 deaths and 19,721 injured, which is 24.2% of Changhua County.
Changhua City averaged 461.2 accidents a month over this period. Within a day the peak hour is 17, at 9.8% of the total; the night hours from 22:00 to 05:00 account for 5.0%; weekends account for 24.6%. Excluding the month still being filled in, the last 12 complete months had 5,702 accidents against 5,717 in the 12 months before, down 0.3%.
Motorcycles account for 59.5% of parties involved. Deaths per thousand accidents is 2.51, below the national average of 4.24. That ratio swings sharply when deaths are few, which is especially true in districts that record few accidents to begin with, so do not draw conclusions from it alone.

Months with no recorded accidents are not listed.
The National Police Agency refreshes its rolling data on the 1st and 15th of each month, so the last month is still being filled in and will always read low. Do not compare it with earlier months.

How to read these numbers
More accidents does not mean more dangerous. Places with more traffic, longer roads and denser population naturally record more. This data has no traffic volume to divide by, so a rate per ten thousand vehicle passes cannot be computed; it can only tell you where accidents actually happened.
The road ranking counts road names appearing in the address. In Taiwan 26% of accident addresses are written as a reference point along a road rather than an exact position, so this ranking is reliable at the level of a road but not at the level of a junction.
Only A1 and A2 accidents, which involve casualties, are included. Property-damage-only collisions are not, so the real number of collisions is higher.
