A Ph.D. Thesis titled ‘Pedestrian behaviour and safety models in urban road networks‘  was presented by Eleonora Papadimitriou in February 2010. A topological consideration of the urban road network was opted for, allowing to identify basic properties of pedestrian trips and crossings, an algorithm was also developed for the estimation of the choice sets related to crossing decisions along a trip and a discrete choice modeling approach is proposed for crossing choices. The proposed methodology was demonstrated by means of models implementation on a typical urban trip for different scenarios.
