Roadside tree inventory for sound barriers
For Rijkswaterstaat, we analyzed vegetation at sites marked for new sound barriers along the Dutch highway, mapping canopy projections for trees and shrubs to guide safe placement.
For Rijkswaterstaat, we analyzed vegetation at a set of locations marked along the Dutch highway network, where new sound barriers were planned to be placed. Using mobile mapping data collected by Cyclomedia, our platform identified canopy projections for both avenue trees and shrub vegetation across each site, giving Rijkswaterstaat the detail needed to plan sound barrier placement around existing greenery.
For avenue trees, we deliver individual tree data like tree location, crown diameter, and stem diameter. For shrub and group vegetation, we deliver per-area data with location, surface area, and average stem diameter.
This distinction let Rijkswaterstaat assess canopy coverage and vegetation structure at each site and identify potential collisions. It helped decide how sound barriers can be placed without unnecessary loss of greenery. It supported planners in the project phase, and later in planning the work and budgeting.
