Taiwanese city trials Korean sunshades, debate over trees vs. structures for intersection shade

Kaohsiung is testing three Korean-style manual retractable sunshades at intersections near MRT stations, with each costing NT$275,000. This initiative has sparked debate, with some advocating for trees as a sole solution for intersection shade.

However, the local group "Good Days in Kaohsiung" contends that relying solely on trees is impractical for intersections, drawing on experiences from South Korea. They point out that the sunshades are installed at locations where pedestrians naturally wait, and their placement does not interfere with sidewalk greening efforts.

The idea that trees should be used exclusively for intersection shade is not feasible based on practical experience in South Korea.

South Korea has widely adopted similar sunshades, with over 10,000 installed nationwide since 2015. These are considered "transportation auxiliary facilities" and are regulated to ensure they do not obstruct pedestrian flow, vehicle visibility, or accessibility facilities. Korean authorities report that these shades can reduce temperatures by over 8 degrees Celsius and have been rated as a highly impactful policy by citizens.

"Good Days in Kaohsiung" argues that while trees are effective for shade, large trees suitable for intersections are not feasible due to space and visibility constraints. They emphasize that the sunshades' placement at intersections is distinct from tree planting areas and does not contradict greening policies. The group suggests that integrating such facilities into pedestrian infrastructure management and road design manuals could be a viable direction, referencing the Korean experience.

The placement of sunshades at intersections is not the same as tree pits and does not conflict with sidewalk greening policies.
