Traffic counts are essential as a basis for solutions to take action against air pollution. Unfortunately counting is currently expensive, limited in time, and rarely records all forms of transport (cars, heavy vehicles, public transport, cyclists and pedestrians).
Telraam puts citizens in control of local mobility policy.
It aims to involve citizens in installing low cost sensors (a combination of a Raspberry Pi microcomputer, sensors and a low-resolution camera) outside the windows of their homes. This can generate widespread traffic counts that can be used to make infrastructure, traffic lights and traffic management plans more efficient and more effective.
