THE EFFECT ON TRAFFIC FLOW DURING TOTAL ROAD CLOSURES DUE TO ROAD REPAIRS

The Metropolitan Expressway Public Corporation began with 4.5 km of roadway in 1962 and has expanded to 231 km, carrying over 1.15 million vehicles per day in 1994. During this period, the Metropolitan Expressways have been linked to the National Highways, further adding to traffic volume. Increased vehicles and aging has led to a rise in damage to the roads, making frequent road repairs necessary. Since 1991, the routes in the Metropolitan Expressway network with detour routes (Routes 1, 6, and 7) have been undergoing repairs necessitating total road closures. In 1994, the construction method, scale, schedule, and the effect on city traffic were investigated to determine whether the same method could be applied on Route 3, which has no detour route. Results of the investigation allowed road repairs to be conducted with total road closure on Route 3. Traffic disorder due to the road closure was not noted during this time period because of early public announcements, detailed planning, and traffic countermeasures. This paper describes the measures taken to create public awareness and the traffic countermeasures instituted to allow maintenance work to be performed. It also describes changes in the traffic conditions during the period of maintenance.
