A paper titled ‘Mobile phone use and traffic characteristics‘ co-authored by G.Yannis, E.Papadimitriou, P.Papantoniou and N.Petrellis is just published in the Traffic Engineering & Control Journal. The objective of this research is the analysis of the impact of mobile phone use on vehicle traffic speed and headways. It was found that vehicle speed is increased for young drivers (aged 18-25 years), male drivers and taxi drivers, and decreased for older drivers (>55 years) and for drivers using their mobile phone while driving. Vehicle’s time headways were not found to be affected by cell phone use. However, headspaces, estimated as the product of vehicle speed and time headways, were found to be decreased for drivers using their mobile phone, young drivers and older drivers.
