WeCount intends to establish a multi-stakeholder engagement mechanism to gather data through road traffic counting sensors in five pilot cities. Data will then be used to formulate informed solutions to tackle a variety of road transport challenges, thus improving quality of life at the neighborhood level. The road traffic counting units are mounted on each participating household’s window facing a road, which will allow authorities to quantify local road transport and the speed of cars, large vehicles, cyclists and pedestrians. The sensors are based on the popular Telraam experience in Flanders. Crowd-sourcing methods provide cost-effective data for local authorities at a far greater temporal and spatial scale than what would typically be possible in classic traffic counting campaigns and will therefore open up new opportunities for transportation policy-making and research.The five pilot cities are Madrid, Ljubljana, Dublin, Cardiff and Leuven.
