This paper investigates the effects of motorcycles on traffic operations at signalized intersections. Field surveys are conducted to study the effects of motorcycles on other traffic by examining discharge headway. It is found that the effects of motorcycles may be measured in terms of an increase in the start-up lost time of signal phase. Presence of motorcycles does not affect the saturation headway of traffic. A microscopic traffic simulation is developed so that effects of motorcycles can be taken into account in the planning and management of urban streets. It is found that our software can replicate the discharge headway as observed from the actual data.
