Abstract

This research focuses on evaluating the row position of
trees planting to the near-road air quality exposed to CO2 emitted from
transportation. Since emission spread quickly to the roadside, it caused highly
concentrated CO2 in ambient air that may harm human health, meanwhile
the roadside is public space for pedestrians. The design of trees planting
is necessarily critical in controlling air quality. This research provides
four positions of trees planting simulated in Surabaya City, Indonesia, and
created the physical condition according to the actual condition in a real 3D
environment. CO2 emission was also calculated based on real data, simulated it
using computational fluid dynamics (CFD) analysis. The result displayed that
the position of trees planting impact on the air quality was caused by
CO2 dispersion. Planting the trees as a barrier between roadside and road in
double-row position is an effective way of decreasing CO2 dispersion.
