In addition to traffic signal synchronisation, other ITS technologies vital to GHG emissions reduction include traffic incident management, ramp metering, construction zone management, traveller information systems, transit signal priority and bicycle signal detection at traffic signals. “Utilising ITS for carbon reduction is aligned with US DoT’s Smart City initiative; California’s emission reduction target’ and the Paris Agreement on climate change,” Morrissey added. “ITS needs to be embraced as a solution.”
