Bayview Avenue is a major arterial road crossing the city of Toronto from north to south, spanning the Don River. The Lower Don River area is prone to flooding during extreme weather events.
The City of Toronto has implemented resilience measures by deploying a traffic management system to rapidly mitigate the impacts of flooding. The Lower Don Traffic Management System (LDTMS) is allowing the city to remotely detour vehicles along Bayview Avenue and adjacent streets, preventing them from accessing flooded zones.
Toronto’s LDTMS consists of 21 highly visible crash tested gates and 41 Blank Out signs (LBO). The LBOs allow the City of Toronto to alert road users of flood events and road closures while efficiently redirecting them. Moreover, the automated gates can be deployed remotely to close key access points, preventing vehicles from entering flooded areas during heavy precipitation.
All ITS devices are controlled and monitored from Toronto’s Traffic Management Center’s ATMS solution (ITS Central from Transnomis). The ATMS connects to seven Versilis Commanders located at each one of the seven access points. Each Commander is configured according to its own site-specific scenario of operation, considering the number and type of devices, their grouping and the predetermined sequence of events.
