Protecting the pedestrian has been talked about for some time yet cyclist safety appears to have only recently been given the attention it deserves. For its part, Dutch firm TNO is developing an external airbag to protect pedestrians and cyclists in the event of a collision. The researchers used simulations, combined with real world accident data, to study the precise areas of the car a cyclist is most likely to come into contact with. Continuing just-auto's series of interviews with companies pushing back the technical boundaries in the active and passive safety arena, Matthew Beecham talked with TNO's project manager Margriet van Schijndel-de Nooij to find out more.
