Transportation Planning
Road, rail, and airport noise studies for infrastructure projects and route optimization. Evaluate noise impacts and design effective mitigation.
Transport Infrastructure Noise
Transportation projects require detailed noise studies to assess impacts on communities along routes. Noise modeling helps planners compare alignment options, design noise barriers, and demonstrate regulatory compliance.
SoundPLAN includes calculation methods for all major transport modes, with source models for various vehicle types, train configurations, and aircraft categories.

Route Optimization
Compare noise impacts of different route alignments, vertical profiles, and design speeds. SoundPLAN calculates population exposure for each alternative to support route selection decisions.
- Horizontal alignment comparison
- Cut vs. fill section analysis
- Speed zone optimization
- Barrier placement scenarios
Barrier Design
Design noise barriers with optimized height, length, and placement. SoundPLAN calculates barrier insertion loss and identifies the most cost-effective configurations.
- Barrier height optimization
- Absorptive vs. reflective surfaces
- Gap and end effects
- Cost-benefit analysis support
