عنوان انگلیسی Pedestrian Gap Acceptance Logit Model in Unsignalized Crosswalks Conflict Zone
چکیده انگلیسی مقاله Pedestrians are the most vulnerable road users. For evaluating and modifying pedestrian safety in unsignalized crosswalks,the first important issue is to identify and explore factors affecting the interaction behavior of pedestrians andvehicles in conflict areas. By analyzing those factors and determining how they affect road user's behavior, we canrepresent the plans and procedures to promote awareness and safety of both pedestrians and drivers. The goal of thisarticle is to study pedestrian decision making behavior in unsignalized crosswalks and to determine factors affectingthe crossing behavior in conflict areas. The supposed goal of this study was assessing how each factor can influencepedestrian-vehicle conflict behavior by means of developing logistic regression models. This work explores a varietyof factors that may impact the gap acceptance behavior of pedestrian to provide a promising decision model. Discretechoice (probit) models of the gap acceptance decision are estimated from observations of pedestrians behavior whencrossing at conflict zone.Analysis results show that variables like vehicle speed change (VSC), pedestrian distance to vehicle lane (PDV), pedestrianage (PA) and vehicle position to the start point of pedestrian (Vp) are effective in Pedestrian gap Acceptance(PGA). Modeling decision making behavior by logit models, resulted in neglected R Square of 0.882 and correctclassification of 94.9 pair wise cases. Area under ROC curve resulted in 0.98 that means the reliability of models isextracted. The results also showed that some variables like vehicle type (VT), waiting time (WT), number of pedestrianswalking in a group (PN) and Gap or Lag are not effective in decision making logit models.
