Day-by-day traffic changes, compared with historical data, and analysis together with related statistics showed the following results: The Western route called Kan-etsudou experienced 20% increase in traffic caused by detour trip toward the disaster region Tohoku during the first week. From the fourth week until mid-July after the earthquake, the average traffic volume increased by 20% compared with 2010, and average trip length increased by 10%. One of the major reasons for this change was that ports in the Tokyo Bay area were used as alternative freight transport routes in place of damaged ports in Tohoku.

  • Promoting Construction of the Three Ring Expressways of the National
    Promoting Construction of the Three Ring Expressways of the National Capital Region Tokyo Metropolitan Expressway Central Circular Route This circular route is approximately 47 kilometers long and links areas within an approximate 8 to 10 kilometer radius from the center of Tokyo. With the section linking the No. 3 Shibuya Route to the Wangan Route completed in March 2015, the Central Circular Route fully opened to traffic. This has resulted in less concentration of traffic in the city center. The volume of traffic in the area within the Central Circular Route (*1) has declined by five percent and time lost due to traffic conges- tion (*2) has gone down by about 50 percent. Among other benefits, the time required to travel to Haneda Airport from Shinjuku during rush hour has been reduced by about 21 minutes. Tokyo Outer Ring Road (Gaikan) This route is approximately 85 kilometers long and links areas within an approximate 15 kilometer radius from the center of Tokyo. Up until now, a roughly 34 kilometer section between Oizumi Inter- change and Misato Minami Interchange has been in operation. Work is currently underway on the section between Misato Minami Interchange and the Higashi-Kanto Expressway, which is due to be completed in fiscal year 2017. In April 2007, the city plan for the section between the Kan-etsu Expressway and the Tomei expressway was changed from an elevated route to an underground route and the project became ready for implementation in May 2009. Currently this project is being carried out by the central government and the East and Central Japan Expressway Companies.
