1970 Taylor Infographic Map of Los Angeles' Traffic

Publication Date: 1970

About this Item

Excellent. Some handwritten annotations. Size 21.5 x 28 Inches. An intriguing infographic map of Los Angeles traffic flows prepared in 1970 by City Traffic Engineer S. S. Taylor. It introduces a novel technique to illustrate traffic density and demonstrates the difficulty of managing the immense number of vehicles transiting the city daily. A Closer Look Coverage includes the area between Robertson Boulevard in the west and Indiana Street in the east and between Forest Lawn Drive (Griffith Park) and Colorado Boulevard in the north to Slauson Avenue in the south, except for the downtown portion of Los Angeles, which appeared on a separate map. Lines represent the traffic density in a weekday 24-hour period along major roads, with the thickest lines representing 40,000 vehicles or more. The most congested part of the city (outside of downtown, at least) was the entrance and exit of the Hollywood Freeway (U.S.-101) along Cahuenga Boulevard, Highland Avenue, and Franklin Avenue, where traffic could exceed 70,000 vehicles per day. Major north-south and east-west corridors such as La Cienega Boulevard, La Brea Avenue, Crenshaw Boulevard, Los Feliz Boulevard, Sunset Boulevard, and Wilshire Boulevard were also especially congested. Even the narrow and winding Laurel Canyon Boulevard far exceeds 20,000 vehicles per day. Though the focus is on local roads (overseen by the city), state freeways and interstates are also traced with their (considerably larger) volume of vehicles, with the most congested part of the Santa Monica Freeway (Interstate-10) exceeding 230,000 vehicles. In sum, this is a fascinating contemporary portrait of traffic congestion in Los Angeles that still rings true for anyone unfortunate enough to have extensive experience driving in the city. Publication History and Census This map was prepared by S. S. Taylor, L.A. City Traffic Engineer, in 1970, though it was not published until 1973, as part of a Central Area Cooperative Transportation Study . It is not independently cataloged with any institution, while the entire Study is only held by the University of California Los Angeles and the Los Angeles Public Library. 'Traffic Flow Maps' from later years are similarly scarce, listed among the holdings of a small handful of institutions (UCLA, LA Public Library, UC Berkeley, and the Metro Transportation Research Library and Archive) in the OCLC.
