Signals will stay green unless traffic approaches at certain pedestrian crossings in Barking and Dagenham, Newham and Tower Hamlets. - Credit: PA Pedestrian crossings in east London are being reprogrammed to stay on the “green man” signal until approaching traffic is detected. In a move to prioritise people walking over driving, 18 crossings in the capital will have the pioneering “green person authority” technology. Two crossings by Devons Road DLR station in Bow, Tower Hamlets and one in Prince Regent Lane by Alnwick Road in Custom House, Newham are among seven locations that have already been upgraded. Crossings in London Road by James Street in Barking and Gale Street by Becontree Station in Dagenham will follow by the end of June, along with nine other locations across London.
