Indeed, a substantial increase in active travel is needed to achieve London’s 2030 target for net zero carbon emissions. Yet, while London’s roads are increasingly popular and safe, more must be done to make them safer. London universities have repeatedly experienced the human cost of unsafe streets, with LSE losing three members of its community in less than a year. In response, staff and students initiated a cross-university letter to the London Mayoral candidates. The letter asked candidates to commit to putting a stop to cyclist and pedestrian deaths caused by motor vehicles in London by 2028, and to bring forward the deadline for London’s ‘Vision Zero’, its strategy to eradicate deaths from London’s roads, from 2041 to 2032.
