The aim of this research is to investigate and model pedestrian road crossing behavior at uncontrolled mid-block in Egypt as one of the developing countries. In particular, two aspects of pedestrian crossing behaviors at mid-block locations have been examined, namely the size of traffic gaps accepted by pedestrians and the decision or not to cross the street, as well as the related determinants. A field survey was carried out at nine uncontrolled mid-block locations in different streets in three Egyptian cities. The locations were chosen with various street crossing widths to test the influence of this variable as it has not covered in previous pedestrian models. In this survey, pedestrian crossing decisions were videotaped in real traffic conditions. The survey period was 30 minutes for each location. Ten JPEG files were obtained from each second of video recording with the help of Snapshot Wizard software. The data collected included traffic characteristics (speed, type, etc.), individual characteristics (gender, age etc.), as well as individual behavior (frequency of attempt, rolling gap, etc.). A lognormal regression model was developed in order to examine the effect of various parameters on the size of traffic gaps accepted by pedestrians. It was found that the accepted gaps depend on the speed of incoming vehicle, the pedestrian rolling gap, the frequency of attempts a pedestrian makes before crossing, the crossing width, and the age of the pedestrians. A binary Logit model was also developed in order to examine the effects of various parameters on the decision of pedestrians to cross the street or not. The results suggest that pedestrians’ decision to cross the street depends on the size of traffic gap, the vehicle speed, the pedestrian rolling gap, and the frequency of attempts before crossing.
