Pedestrians are vulnerable road users therefore, it is necessary to analyze their behavior in order to define quality measures. This paper reports the comparison of pedestrian crossing behavior at signalized and unsignalized intersections in Addis Ababa. The objective of the study is to find the factors that affect pedestrian crossing speed and waiting time and to provide MLR model for both intersection types With specific of two signalized intersection those are legehar and kidist maryam and two unsignalized intersections those are 4 killo round about and safari uncontrolled intersections. For each crosswalk observation was taken at 7:30A.M to 8:30A.M. Data collection was taken by video observation. For the study total of 2374 sample of pedestrian are used. Different parameters are taken to test the significant factors those are Gender, Age group, Baggage handling, crossing stage, crossing direction, crossing patters, crossing situation, disability, mobile usage and crossing along the crosswalk. Student t-test and one way ANOVA were used to identify factors affecting pedestrian crossing speed while Mann-Whitney U test and Kruskal-Wallis one way ANOVA test were used to identify determining factors of pedestrian waiting time. Male pedestrian, young pedestrian, pedestrian alone, pedestrian with no disability and pedestrian with no mobile usage cross faster. From the analysis of the crossing speed mean crossing speed is found as 1.41m/s and 1.27m/s and the recommended design crossing speed are 1.02m/s and 0.95m/s for signalized and unsignalized intersection respectively. For a better understanding, MLR model method was applied at 95% confidence interval, which showed gender, age group, crossing stage, crossing pattern, crossing situation, disability and CAS- crossing along the crosswalk as the significant factor for the crossing speed. In the case of waiting time, 40%, 69% and 91% of pedestrian doesn’t wait more than 10s for signalized and unsignalized intersections respectively. Females, old pedestrian, pedestrian with no baggage, two stage crossing, crossing by walk, being alone, crossing without mobile taking, pedestrian with no disability have higher waiting time. For a better understanding, an MLR model method was applied at 95% confidence interval was prepared for the waiting time of pedestrian analysis, which showed gender, age group, Crossing stage, crossing pattern, crossing situation and CAC- crossing along the crosswalk.
