Taoyuan Testing "3D" Optical Illusion Speed Bumps|提醒駕駛減速 桃園創"駝峰"減速丘

Traditional speed bumps or road markings cautioning drivers to slow down often result in noise pollution and cars slipping and sliding. Taoyuan is the first municipality in Taiwan to remove physical speed bumps in favor of optical illusion speed bumps to remind drivers to reduce their speed. The optical illusion speed bumps are being tested at intersections that are frequently the site of accidents. Taoyuan is also taking inventory of high-speed intersections without traffic signs.


These protruding speed-reduction lines are a source of noise pollution and a headache for local residents. They also pose a driving hazard, as they can cause drivers to temporarily lose control of their vehicles. Taoyuan recently became the first municipality in Taiwan to start using optical illusion speed bumps.

The speed bumps cause so much noise when someone drives over them. (Is it better now?) It's a lot better. There's no more noise. It's very quiet. You see?

The section of Mingzu Road from Datong Road to Mingzu Tunnel is a major access road for the train station. However, drivers often can't see oncoming traffic due to the bridge blocking their view and 26 injury-causing accidents took place here last year. The Department of Transportation therefore decided this was the best place to test its new 3D speed bumps.

(They) create a kind of visual pressure for road users. They see something in their line of vision, which isn't actually there. Driving over it is also impactless, but it is a very effective way to get drivers to slow down.

The department says it will test the new speed bumps at intersections that are frequent accident sites to see if the number of accidents goes down. It will also take inventory of high-speed intersections without traffic signs.
