Compete With Arterials, Not Just Freeways

In the US, we often mentally organize cities by their freeways, and consequently we often conceptualize potential transit as mimicking the freeway network. Hence we think of north-south transit between the Westside and the Valley as “the 405 Line”.

But as Cap’n Transit would remind us, transit is competing with parallel facilities like freeways. If the freeway is a total basket case, like the 405, you’ll probably do fine. But in a place like Orange County, even the heavily traveled freeways are going to offer faster average speeds. Where transit and freeways compete, freeways often come out on top, partly because medium distance trips are the sweet spot for freeways – trips that are long enough to make freeway access time worth it because of the higher speeds freeways offer.

However, transit is also in competition with arterial roadways, mostly for trips for which freeways can’t compete. These are shorter distance trips, where it’s not worth the time to get to and from the freeway, as well as medium distance trips where there’s no freeway available. In fact, even in LA County, the best performing LRT lines are the ones that are not directly in competition with a freeway: the Blue Line is somewhere between the 110 and the 710, and Expo Line Phase 1 is about a mile from the 10 (and benefits from the truly abominable traffic). Meanwhile, the lines that directly compete with a freeway (the Green Line and the 105, the Gold Line and the 110) achieve fewer boardings per mile.

It follows that we could find some clever and unexpectedly successful LRT or BRT routes by looking for long, straight arterial corridors that are serving short distance trips and medium distance trips where there’s no freeway available. In fact, we already saw a couple such potential routes when we looked at Sepulveda Pass/LAX transit: Reseda, Balboa, and Lincoln are long arterial corridors where there’s no practical competing freeway.

Where else do we have potential corridors like this? Here’s a few that come to mind:

  • Beach from Huntington Beach through Westminster and Stanton to Buena Park (or maybe La Habra)
  • Harbor from Newport Beach and Costa Mesa through Garden Grove and Anaheim to Fullerton (or maybe La Habra)
  • Florence from Westchester through Inglewood, South LA, Huntington Park, and Bell Gardens to Downey
  • Lakewood from Pico Rivera through Downey, Bellflower, and Lakewood to Long Beach
  • Hawthorne in Torrance
  • PCH from LAX to Long Beach
  • Imperial from Norwalk through La Mirada and Brea to Yorba Linda
  • Whittier from East LA through Montebello, Pico Rivera, and Whittier to La Habra
  • Azusa from Industry through Covina to Azusa
  • Rosemead from South El Monte through Rosemead and Temple City to East Pasadena


At the moment, I’m finding the first two the most intriguing. The others are good candidates for sure, but I like the idea of a sneaker route in Orange County, connecting the beaches to Metrolink. Beach is a good five miles from any competing north-south freeway. Harbor probably has better destinations but is closer to the 55 and the 57.

The problem to watch out for with routes like this is making sure there’s enough development to justify the route. Odds are the biggest destinations have freeways between them, but you can still find routes that make sense. I may revisit one or several of these corridors in more detail in the future.

    I would have thought of Santa Monica Blvd as an obvious candidate too, but are you thinking of the Red Line, Purple Line, and the “Pink Line” extension of the Crenshaw Line as already filling that?

      Santa Monica is another great candidate. Wilshire is too, of course, and it’s getting bus lanes and subway. I sort of left out everything on the Westside and Central (La Cienega, La Brea, Western, Venice), partly because some of those corridors already have “Rapids” & partly because we already realize the transit potential in that area. Western fits the bill the whole way from Hollywood to San Pedro though, and Santa Monica Blvd would really benefit from at least bus lanes!

      Start where you already have the demand, right?

      Thanks for the link; that’s a great map. As you’d expect the performance falls off south of the 405 and north of the Riverside Line. Harbor does look a little better than Beach. The other interesting thing to note is how much better the gridded section (west of the 55) performs compared to Irvine and southern Orange County. Irvine, at least, could be better by going with a grid. It’s a little surprising there’s nothing south of the 133 and east of the LOSSAN corridor, given that portion of Irvine is booming. They’re probably due to revamp service.

      As far as LRT vs BRT, given the nature of development in Orange County, it probably makes sense to focus rail investment on LOSSAN and have everything else be bus for the time being. The gridded bus routes could be improved for less money & more quickly, spreading the benefit systemwide rather than being focused on a single corridor or two…
