Nan’ao Township road accident hotspots and casualties

From 2024/01 to 2026/08, Nan’ao Township recorded 174 casualty road accidents, 1 deaths and 226 injured, which is 0.8% of Yilan County.

Nan’ao Township recorded only 174 accidents across these 32 months (records in 30 of them). The counts and casualty figures are actual records and can be quoted directly. The percentages, hourly distribution and rankings derived from them swing wildly at this sample size — one more or one fewer accident changes the result — so they should not be used to rank this area against others.

Nan’ao Township averaged 5.4 accidents a month over this period. Within a day the peak hour is 13, at 9.8% of the total; the night hours from 22:00 to 05:00 account for 13.2%; weekends account for 35.6%.

Motorcycles account for 42.8% of parties involved. There were 1 deaths in this period. With numbers that small it is not meaningful to convert to a death rate and compare with other areas — a single accident moves it by several times.

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.
