A Diploma Thesis titled ‘Ιnvestigation of the minimum gap from the vehicle accepted by the pedestrian for urban street mid-block crossing’  was presented by Athanassios Theofilatos in March 2009. A lognormal regression model was developed in order to investigate the influence of certain parameters in the minimum pedestrian gap acceptance. It appeared that the distance from the vehicle, illegal nearby parking that may affect pedestrian’s visibility, the vehicle size and possible companions have statistically significant impact to the minimum gap acceptance. Concerning the choice to cross the road or not, the waiting time and the gap between the pedestrian and the vehicle strongly define his decision.pdf5 ppt5
