Kaohsiung uses smart sensors to detect falling roadside trees
2026-08-03
To prevent roadside trees from falling down and causing damage, the Kaohsiung Public Works Bureau has installed smart monitors on the trunks that can keep track of tilt angles, tipping off a potential accident before it ever happens.
A brown plastic box recently appeared on this tree trunk. It’s actually a sensor that can provide great protection for passing pedestrians, despite its small size.
- From street surveys, we’ve found some medium-risk trees.
Staff sitting in the office can use their computers to monitor the trees in real time. To prevent collapse, the Kaohsiung Public Works Bureau first set up 380 tilt monitors at key points along major thoroughfares. If the angle exceeds 2.5 degrees, personnel are immediately dispatched to check.

If there’s a relatively severe tilt detected, the device can quickly transmit a notification to our staff.
If an abnormality is detected, the city can quickly go address it by trimming branches or anchoring the tree to keep it from falling. If there’s no way to correct it, cutting it down is also an option.

This approach is much more precise than relying on the naked eye, so I think it’s quite good.

Feels safer
Since it can monitor when a tree is tilting and give an early warning, I think it makes it much safer for people.
Trees that are unhealthy or unstable are at risk of falling. Using this system ensures that any potential dangers can be tracked in real time and handled quickly. The city plans to keep expanding the system in the future to ensure the public’s safety.

防倒塌! 高雄建置智慧監測系統 感測行道樹”傾斜角度"
2026-08-03
為了避免路樹倒塌，帶來不可預知的危險。高雄市工務局，特別建置了行道樹的智慧監測系統。透過裝在樹木上的感測器，掌握傾斜角度，提前預防樹倒意外的發生。
粗糙的樹幹上，出現一個褐色的長方體塑膠盒，其實這是個感測器，雖然體積小，卻能給行經的用路人，大大保障。
- 做行道樹普查，在裡面挑選一些中風險的樹木
人員坐在辦公室內打開電腦，就能從系統上及時監測。為了提前防範樹倒風險，高雄市政府工務局，先針對市區重要道路，建置了380處行道樹智慧監測點，來監測路樹傾斜角度，若是超過2.5度警戒值，維管單位就會立刻派員到場勘查。

“倘若發生一些，較為大幅度的傾斜的時候，我們就可以透過這個機器，很快速的去傳遞給我們，即時的一個訊息”
發現異常，人員第一時間到場修剪、固定，降低樹倒可能，若真的無法改善就會安排移除。

“這樣的做法，會比我們人用肉眼看更精準，所以我覺得是不錯的”
[[民眾]]
“因為它可以監測到，這個樹木萬一傾斜，可以先預知，對民眾的安全很有幫助”
樹木若是不健康或結構不穩也有倒伏風險，透過這個監測系統提前防範，也讓這些樹木狀況被及時掌握，市府未來也將持續擴大監測範圍，保障市民的通行安全。
