505			_aABSTRACT: Start-up lost time is one of the parameters of a signalized intersection that measures the efficiency of the road. It displays the difference between the drivers traffic and behaviors. Perception and reaction time vary from driver to driver, and this heavily influences the value of start-up lost time. The introduction of signal countdown timers at signalized intersections intends to reduce this conflict and other traffic problems. Meanwhile, Manila, the capital of the Philippines, has felt a surge in the volume of road vehicles in the post-COVID period. The traffic congestion pushed people to look for alternative means of transportation, which is by riding a motorcycle. This led to the evaluation of the start-up lost time of motorcycles at signalized intersections with a signal countdown timer (SCT) and without an SCT using headway distribution analysis. The evaluation of the study was based on the field data collected at the two intersections in Manila. Different traffic parameters were collected, evaluated, and analyzed under the different countdown timer states. It has been found that the start-up lost time of a motorcycle at the intersection with SCT is 1.65 sec/cycle/lane, which is relatively lower than that at the intersection with non-SCT, with a start-up lost time value of 1.82 sec/cycle/lane. On top of that, the start-up lost time of motorcycles at both intersections has outperformed the 2.00 sec/cycle/lane fix value of start-up lost time proposed by the Highway Capacity Manual. Additionally, the saturation headway at SCT intersections was lower than that at non-SCT intersections; this means vehicles at SCT intersections cross the road rather than those at non-SCT intersections. A higher capacity of signalized intersections was also evaluated when SCT was present. The study found that the presence of a signal countdown timer increases the operational performance of signalized intersecti
