| 説明 | 1935 from John Paver and Miller McClintock, Traffic and Trade. Source for present.Intriguingly different from the present: there used to be a pedestrian dinner dip followed by a second peak, and there was not an AM vehicular peak!The missing third figure is the *huge* AM and PM transit peaks in 1935. |
