Technical Tours


Company Name: Q-Free

Presenters: Pat Marnell & Steve Mager

Project Title: Snohomish County, WA Adaptive Signal System

Virtual Technical Tour Summary:   

Q-FREE currently has an adaptive traffic signal control system that operates along 6 major corridors within the Snohomish County at 49 signalized intersections. Q-FREE envisions that the implementation of adaptive signal control technology at signalized intersections will optimize traffic flow and improve safety on the corridors. This adaptive technology utilizes industry-leading algorithms implemented locally at the intersections. Since Snohomish County does not have a standard traffic management center (TMC), this allows for a mobile TMC. 

This tour will showcase drive-through video footage of some of the selected project corridors in Snohomish County, a close-up of some of the included intersections, live footage of the project area where the adaptive signal system is deployed, and a demonstration of the system to show how the adaptive system works in real-time. This tour will also delve deep into the hardware and software aspect of the adaptive signal technology and how the adaptive signal algorithm works. 

Q-FREE plans to expand the selected adaptive signal system beyond this initial deployment in Snohomish county to include an additional 32 intersections. 


Company Name: Stantec

Presenters: Sumeet Kishani & Cynthia Albright

Project Title: Real-Time Analytics for a 700-km Corridor

Virtual Technical Tour Summary:   

Stantec has implemented a real-time traffic monitoring system for a 700km corridor between Edmonton and Vancouver in response to the challenges with standard traffic monitoring methods in the region. This tour will present video drive-throughs of the project area and provide an in-depth look at the software interface. The details of how the real-time analytics for the 700-km corridor were developed will be discussed. As well, the numerous measurement strategies utilized, and the types of data that was collected to enable the identification of high traffic areas and view congestion in real-time along the corridor will also be presented. Furthermore, this tour will show how this data was used to prolong the onset of congestion in real-time in the field by effectively identifying external factors that contribute to congestion.
