A paper titled “Safety culture among bus drivers in Norway and Greece” authored by Tor-Olav Nævestad, Ross O. Phillips, Alexandra Laiou, Torkel Bjørnskau, and George Yannis is now published in Transportation Research Part F: Traffic Psychology and Behaviour. The aims of this paper are to: (1) Examine the influence of national safety culture, sector safety focus and organizational safety culture on the safety behaviours of professional drivers, compared with other explanatory variables (e.g. age, type of transport, working conditions), and to (2) Examine the influence of safety behaviours and other factors (e.g. age, mileage, type of transport) on self-reported crash involvement. The study indicates a relationship between national road safety culture, road safety behaviour and crash involvement, that could be developed further to help explain differences in national road safety records.
