Many pedestrians are found to indulge in unsafe road crossing at both the signalized and non-signalized crosswalks. The objective of this paper is to study and compare unsafe pedestrians’ crossing behaviour at a signalized and/or a non-signalized crosswalk. F and t tests are performed to observe which crosswalk has the larger mean and variance of the available gap-size in the traffic flow and waiting time of pedestrians. Logistic regression models are fitted to examine the pedestrians’ risk and unsafe road crossing behavior at two crosswalks. Mean and variance of available gap size and waiting time to pedestrian at a signalized cross walk is larger than a non-signalized crosswalk. At a signalized crosswalk, probability of crossing by a pedestrian with the gap size less than the adequate gap size is about 98%; and at a non-signalized crosswalk it is about 95%. At a signalized crosswalk only gap size parameter is significant. However, at a non-signalized crosswalk other predictor parameters (such as gender of the pedestrian, whether alone or in a group, type of the conflicting vehicle and traffic volume) are significant in determining the pedestrian road crossing behavior. The odds of an unsafe road crossing by a pedestrian at a signalized crosswalk is about 1.7 times higher than that at a non-signalized crosswalk. Pedestrians unsafely cross roads when gaps are available within the traffic flow, at both signalized and non-signalized crosswalks. Thus gap size is a significant parameter to determine the pedestrians’ unsafe road crossing behaviour at both crosswalks.
