Special events may cause significant disruptions to the community and affect the daily lives of the local residents. This study examines how local residents perceive the traffic impact of a major tourism event, the Macau Grand Prix, which is an annual event that takes place on a circuit around the streets of the city, Macao. An exploratory factor analysis reveals five factors regarding the traffic impacts of the event, and the residents of different transportation modes have distinct views on the traffic measures. Bus transit and pedestrian traffic management is found to be the most effective. The result provides the event organizer implications and assessment for the traffic planning and management measures in gaining support from the community.
