3D TREE MODELLING FOR LESS NOISE

3D TREE MODELLING FOR LESS NOISE

Announcing our latest publication, “Improving Traffic-noise-mitigation Strategies with LiDAR-based 3D Tree-canopy Analysis,” in Geomatics and Environmental Engineering journal (Vol. 18, No. 3, 2024)! This groundbreaking study explores how trees can be our green heroes, reducing traffic noise naturally.

Our team used cutting-edge LiDAR technology to create 3D models of tree canopies. We analyzed how trees’ leaves and structures absorb traffic noise.

We developed a new equation to measure noise reduction, integrating it with existing models. Our findings show that trees can reduce traffic noise by 1 to 3 dB(A).

LiDAR-based 3D visualizations provide accurate data for better urban planning. Tree belts and dense planting schemes are particularly effective in noise mitigation.

Our discoveries pave the way for greener, quieter urban spaces. Imagine strolling down a city street with less noise and more peace—thanks to thoughtful tree planting!

Join us in celebrating the power of nature and technology to improve urban living. Let’s make our cities not just smarter, but also greener and more serene!

FROM MPHIL TO PROMOTION – NEVIL’S INSPIRING STORY

FROM MPHIL TO PROMOTION – NEVIL’S INSPIRING STORY

I am thrilled to share a moment of pride and achievement as my supervisee, Nevil Wickramathilaka, reaches a significant milestone in his career. After completing his MPhil in Geoinformatics at Universiti Teknologi Malaysia with a perfect CGPA of 4.00, Nevil has not only excelled academically but has also made remarkable contributions to the field.

His dedication over the past two (2) years has been truly inspirational. Nevil has published five (5) journal articles in renowned Scopus/WoS indexed journals, presented his innovative research at four (4) international conferences, received two (2) prestigious awards, and registered three (3) intellectual properties related to his groundbreaking work in traffic noise visualization and noise absorption assessment via spatial interpolation.

Today, I had the honor of writing a recommendation letter for his promotion at John Kotelawala Defence University, which reflects his hard work and potential. His promotion comes with a well-deserved salary increase of around 150%.

“Success is no accident. It is hard work, perseverance, learning, studying, sacrifice, and most of all, love of what you are doing or learning to do.” — Pele

WIND IN THE URBAN CANVAS – 3D BUILDING IMPACTS EXPLORED

WIND IN THE URBAN CANVAS – 3D BUILDING IMPACTS EXPLORED

Exciting News! Just published my latest research on “Investigating the Influence of 3D Building Models on Pedestrian Wind Comfort through Wind Computational Fluid Dynamics Analysis”!

Curious about how the shape and detailing of buildings impact wind flow patterns and velocity, influencing pedestrian comfort? This study dives deep into the realm of Wind Computational Fluid Dynamics (CFD) to unravel the secrets of wind behavior around 3D urbanized building models.

The findings? Diverse effects due to different building detailing, leading to multiple flow patterns and changes in wind velocity. The downstream building recorded lower velocity, thanks to wind flow separation from the building frontal. Wind comfort levels? All in the good range, falling within Beaufort wind force scale levels 2 and 3.

This research underscores the crucial role of building models in shaping wind flow patterns and velocity, ultimately impacting Pedestrian Wind Comfort. Despite varied building shapes and detailing, the wind comfort levels were suitable for pedestrians.

Ready to explore the dynamics of wind and buildings? Swipe through my publication for an in-depth look!
