Short answer: Vista, Hayworth, Hacienda, West Knoll (speed); Gardner, Cynthia, Laurel (volume)

Note: This is a new look at the City speed and volume data we discussed in our September article. It covers residential streets only. We’ll look at arterial streets like Santa Monica Boulevard in a future article.

The City measured traffic speeds and volumes for 131 segments of 72 residential streets in West Hollywood. Segments of Gardner, Cynthia, and Laurel had the most traffic, measured in vehicles per day. Segments of Vista, Hayworth, Hacienda, and West Knoll had the fastest traffic.

We’re measuring “fastest” in terms of the “85th percentile” speed. It’s not the maximum, but it’s close. If seven people drive by, it’s the speed of the second-fastest driver. One driver is going faster, while the other six (85%) are going that speed or slower.

The speed and volume numbers are shown for each street segment in the table below, along with street widths, area of the city (westside, center city, or eastside), whether it’s north or south of Santa Monica Boulevard, and the address of the measurement point. The numbers were last updated in July, 2014. You can sort the rows by clicking on the column headings and scroll by clicking on the scrollbar. (If you can’t see all of the columns on your mobile device, please try turning the device horizontally.)

Two street segments — Vista south of Santa Monica Boulevard and Sweetzer north of Santa Monica — are called out in both charts. That part of Vista is unusual. At 65 feet, it’s wider than the adjacent Santa Monica Boulevard.


Parts of the city with the highest speeds/most traffic

Which parts of the City have more streets with higher speeds and volumes? The answer is center city north of Santa Monica Boulevard and the westside north of Santa Monica. The table below shows the street segments with the highest speeds (s = 27 mph and up) and volumes (v = 4,000 vehicles per day and up).
