Project Description

This project involved the extension of the Mississauga Transitway from Winston Churchill Boulevard Station to Highway 407, in the City of Mississauga. Noise sources that were assessed included vehicular traffic on Highway 403 and Ridgeway Drive, and the proposed Transitway bus volumes.

Engineers undertook a noise impact assessment to evaluate the impacts of the proposed bus rapidway on nearby residences. Transportation noise prediction was undertaken as per the Ontario Road Noise Analysis Method for Environment and Transportation (ORNAMENT) using the MOE Stamson software. Work also included a noise monitoring component to document baseline sound levels in the vicinity of the nearby noise sensitive areas that could be impacted from noise created by the proposed transitway. Based on the findings of the study, the noise impacts at the nearby sensitive land uses are expected to fall within the Ministry of the Environment, Conservation and Parks (MECP) sound level limits. Thus, the implementation of this project will not be constrained by noise and will not require noise mitigation measures.

LEA engineers Tony Chiu and Felipe Vernaza completed work on the project while employed with a previous firm.
