SkyTrain Noise Study

 

We want to be good neighbours, so TransLink is conducting a multi-step SkyTrain Noise Study. In response to noise concerns from residents along the Expo and Millennium lines, we have engaged an internationally-recognized acoustic engineer to assess noise levels along the Expo and Millennium lines and to evaluate possible noise-mitigation options.

 

First Steps

During the initial assessment, extensive noise measurements were conducted in 10 study areas along the Expo and Millennium lines. The results were used to create a detailed sound model, which highlighted sources of noise that exist in the SkyTrain system and areas most in need of noise-mitigation measures.

The results show that there is relatively little difference in noise levels between train types and that track condition is the main contributor to noise rising to levels above desired thresholds, which is further amplified with higher train speeds. You can find more details in the full report or the summary report.

 

Next Steps

Over the coming months, TransLink will investigate the feasibility of a variety of noise mitigation measures to address the complexity of SkyTrain noise and develop noise guidelines for residential developments.

Thorough pilot programs and further studies are needed to understand the effectiveness, costs and operational considerations for each noise-mitigation option. These findings will inform priorities for future investments with the intent of reducing noise levels and improving the liveability of communities near the SkyTrain system. We expect to have more details about which options are feasible later in 2019.

This work is more important now than ever before as Metro Vancouver continues to grow and more people choose to live near our rapid transit lines. The results of the study will help us identify noise-reduction measures for our 30-year-old system and inform future designs and investments with noise reduction in mind.

 

Community Input

Using records of SkyTrain noise-related customer complaints from between 2014 to 2017, we were able to identify the 10 study areas upon which to focus. The study has been supported by a community advisory committee comprised of 15 people who reside in these 10 communities.
