Almost exactly a year ago, we reported on a residential street in Cardiff which had a quarter of a million car and HGV journeys in one month. Residents in Pen-y-Wain Road say the noise and pollution was unbearable with almost 350 cars passing every single hour on average.
12 months on, the street - along with Shirley Road which leads into it - continues to experience an exceedingly high volume of traffic. In just six months, Pen-y-Wain Road has seen more and 1.1 million car and HGV journeys along it, while Shirley Road has seen more than 1 million.
These figures come from low-cost sensors called Telraams supplied by WeCount, an EU-funded project that enables concerned citizens to count traffic. The project has since ended, but the sensors remain.
