Annual Key Performance Indicators
Every winter, the Mobility Division publishes an annual progress report on our key performance indicators. We dig into trends for transit ridership, pedestrian, bike, and motor vehicle traffic, collected speed data, Bluebikes ridership, and reported crash data. We also report on key safety deliverables such as traffic calming installations and newly constructed safety and comfort improvements.
What is an air source heat pump and how does it work?
Air source heat pumps are appliances that provide heating and cooling by moving heat into a building (for heating) or out of a building (for cooling). Heat pumps do not create heat, they just move heat from one place to another.
