Thank you, Gary, for your visual real-world example of the "hogging" issue that Menlo Park residents will have to face trying to get home with the new partial cloverleaf that is being built right now. @CALTRANS - Please develop a mitigating solution that will enable Menlo Park-bound traffic (westbound) to exit the freeway at Willow Road and avoid the extensive backup that the Dumbarton Bridge-bound traffic (eastbound) creates. One suggestion is a dedicated exit lane added to the existing 2 lanes, dedicated for Willow Road westbound only traffic. The key to making this work is to locate the exit as far north on 101 as possible, to avoid most or all of the backup. Even better would be an additional exit lane on 101 Southbound that feeds into this dedicated exit.
Ken Hoyle: Personally, the mitigation that I prefer would be to add back an exit loop on NB 101, which would probably eliminate the opportunity to add metering lights for the NB 101 entrance loop from Willow EB, but they could remain on the Willow WB to 101 entrance ramp. Not having those would not have much impact since the traffic entering 101 there during the PM rush hour is less than the traffic exiting at that time.
This does not make sense. The traffic in the other lanes of 101 seem to be moving along just fine so it is safe to assume that the 92 east exit is not backed up. So why are all of these cars getting off at Hillsdale to get on the SM bridge? I think it is much more likely that these cars are not going to the SM bridge at all. They are just Foster City residents trying to get home.
McGovern Family: Your speculation is probably not accurate, but either way irrelevant to the important question of how partial cloverleaf interchanges perform in the circumstance of asymmetrical traffic (i.e. Much more heading east than west (or vice-versa)). Whether they are headed to Foster City, the east bay or NYC does not matter. What matters is that they block west-bound cars from reaching the intersection when they should. There are other adverse things that matter, but I am only addressing the main point.
Well, first, I'm not speculating. I am pointing out that the description of the video is not accurate so you fail to make your point. Why would all of those cars be taking the Hillsdale exit to get onto 92E? Is it a shorter, faster route to the bridge? No. Especially when the Hillsdale exit is already backed up and the 92E exit is obviously not. It just doesn't make sense. Those cars are not headed for the bridge. They're going to Foster City. You might be right about the partial cloverleaf interchange issue but this video does nothing to help make your point. That's all I'm saying.
McGovern Family: I suggest that you either look at Google Maps's traffic at the appropriate time, ask someone who regularly drives it or drive it yourself. Many things are baffling that are facts. These are too. Yes, you ARE speculating.
Ok, fine. I'm speculating. As are you. Please, tell me WHY all of those people are choosing to exit at Hillsdale to get on 92E when the 92E exit is not backed up. Gary, I don't like traffic any more than you do and I'm not just trolling for something to argue about. My intent is not to squash your point. I think your video is very nice. I just do not think it presents the evidence that you say it does. There are better examples of the phenomenon you are trying to point out. For example, the Marsh Road exit off of 101 South. Most of the cars that exit there every afternoon are headed for the Dumbarton Bridge. Those who want to turn right to get to MP or Atherton are often forced to wait in that back-up. Maybe the new Willow Road interchange will alleviate some of the back-up at the Marsh Road exit? By the way, my name is Patrick and I do not represent the opinions of my entire family. I just happened to be logged in as such when I commented on the video.
You seem to be hung up on an issue that does not pertain to the subject of my video, but I will indulge you: since we are not in the same vehicle from which I can say "look over there at the slow traffic on 92," I suggest that you look at Google Maps's display of typical traffic for the PM rush hour (e.g. 5:30PM). In case you don't know how: on a computer's web browser, look at the intersection, turn traffic on, at the bottom of the page click on "live traffic" and change it to "typical traffic." Then select a weekday and move the slider to about 5:30pm. What you will see is that the 92 backup is dark red (not just red), which means very slow. Hillsdale is just red. Also, the dark red extends to all three ramps of the 92/101 interchange. This doesn't get any faster until the first exit in Foster City, Edgewater Blvd./Marina Island Blvd. After that it speeds up to red. Given that, it appears that it IS faster to get to the SM bridge via Hillsdale Blvd...but as I said in my first reply, it is irrelevant where they are heading. The video's purpose is to illustrate the phenomenon that I named "hogging." You say that it does not illustrate the point that I say it does. I think it does very clearly so perhaps you misunderstood what it was meant to show. I suggest that you play it again with the volume turned up.
Thanks Gary. Well done.
