Intersections have primary importance in urban networks because most of travel time is wasted at the intersection specially signalized category. Popular solutions of intersection control need to use artificial objects such as speed hump or signals. If both solutions were used together, it causes a manifestation of the delay problem. The study aims at analyzing the impact of speed hump on signalized intersection act in case of traffic mix nature. Quality features such as delay, level of service, and saturation flow rates had been measured and compared for the two consecutive signalized intersections that have approximately the same geometric and operation features in Port Said city. The first intersection has a speed hump and the other is without a speed hump. The study investigates that the existence of speed hump causes the increasing of the average delay by 4.3 %. Also, about half of green time is spent to pass the speed hump. Moreover, the saturation flow rate decreases by about 7 %. The speed hump adjustment factor is 0.93 that declares the harmful impact of speed hump on the saturation flow rate thus it effects on the whole performance of the intersection.
