    Something they could stand to learn around here, but NO, they use it as a way of speed enforcement to make sure that you hit every light on red.

    Traffic lights have long been synchronized along stretches of certain roads, but interconnecting an entire city is new. I wonder how sophisticated their software is, and what the real-world result will be.

    I'm particularly interested in whether they will retain local dynamic-control, with in-pavement and overhead sensors to detect traffic pattern changes, and how that would integrate into the larger grid of traffic lights.

    I happen to dislike in-pavement magnetic sensors, BTW, because they often won't detect lighter and mostly non-ferous motorcycles, that therefore get stuck at lights that won't change, especially left turn green arrows across traffic. Some States have even passed traffic rules that allow you to go through a red light if it doesn't change in a reasonable time. Overhead sensors using non-magnetic means are better at responding to bikes, but are not as common as the wires in the road surface.

    Yeah, tell me about it....

    There is an intersection about 300 yards from my house; 3 way intersection, and if the through street gets a red light, it lasts about 5 min......really, I've timed it. Worst part is the light will turn red even when NO ONE is waiting to do a left turn or come from the side street....it just goes red.

    It will sure be interesting to see the impact if any in LA. I didn't personally have huge issues with LA because over the years I got my life wired in such a way that I drove little and walked or used my bike to get most everything done. True, I put close to 8,000 miles a year on the bike, but the reward was an ass as hard as steel icon_rolleyes.gif. The biggest issues I had was getting to late afternoon / early evening old car hangouts. That put me in rush after traffic a couple times per week such as Bob's Big Boy in Toluca Lake on Friday night and the Great Auto's hangout down in Long Beach or the mid valley.

    Cary went with me frequently so I could use the car pool lane, but it sure makes one nervous at 75 mph right next to the center concrete divider coupled with the possibility or probably that some idiot will pull into the HOV lane from the stopped traffic lane while I'm driving a 50 year car with 50 year old brake 'technology'..

    From the video it looked like they were using overhead sensors that should detect motorcycles. I know they've been working on this idea for a long time so I'm real curious to see if they can get it right. Hope so as I am going back out there after nature takes its course with my ailing parents.

    At least when I got all the way up there to Bob's in Toluca Lake, my special little space was there for me and all was great for the rest of the evening.

    I hate to be so negative but I can see LA screwing this up for a LONG TIME before it actually becomes anything remotely positive. These are the people that built a surface-level light rail line that doesn't receive any level of signal priority at intersections (The Expo Line).

    not only that, but it's gonna screw up my secret speed routes to all my favourite places . it'll be like learning to crawl all over again. damn technology!

    Long Beach is different. The traffic coordinators made sure that all lights are in sync as you travel the main streets. Never wait long too. San Diego I think is the worst. You have to wait forever at lights. You can complain to your city if a street light is set wrong.

    argh! they don't pick up my Roadster either!! There's a left-turn light on my way home that makes me sit for 20min! NO JOKE!!

    So many of the signal boxes in New Orleans are old mechanical style systems. When it gets very cold outside some of them gum up and a yellow light will last 60 seconds or longer

    There's one light like that on my way to/from work. I frequently run it when no cops are around.

    I've considered it often, but there is a police precinct house about a block up the cross street; usually at least ONE patrol in the area, so its too risky.

    Driving in LA blows no matter if the stop lights are in sync or not.

    those are quitter's words

    not sure how long you've lived here but i could show you all the urban assault driving/routing tecniques to make living in LA a dream. it's all about mentally breaking down the freeway/surface st. ratio, and then sometimes you just gotta go with the gsxr and drive between the lanes..

    Lol, well thanks. I said that with slight humor because I actually love driving and LA traffic doesn't bother me. I figure it comes with the territory icon_smile.gif

    But I do have a friend who knows every back route and such and his driving is soooo much quicker lol

    You should know by now, when you enter an intersection and you hear a horn honking.. it's usually someone running a red light. Usually bus drivers cuz they don't to get stuck at a red light for 20 minutes. icon_lol.gif

    After 30 years in LA, I seldom got really stuck IF i was paying attention enough to notice a big backup ahead and get off the frewway quick enough to surface street the rest of the way.

    Just avoid the 405 at all costs, and things will be ok.

    I've been gone for two years, but I thought it was better now since the addition of the lanes. I know going NB the reconstruction several years ago of the 101 & 405 interchange seemed to help

    remains to be seen, highly doubt they even did it the right way, and on the streets that matter most, sometimes i think the lights are timed wrong in business districts so that people can window shop while stuck at a light, driving people traffic into stores, "oh look marge, they are having a sale", the other problem with traffic light timing in LA is the "button pushers", sooo many dam people walking around, traffic has to stop for people or people pushing the light changer at an intersection, that fucks up the timing, and dont get me started on left hand turn lanes, sometimes waiting 3 lights to make a left with only 2 cars making it thru a turn at a time, argggggggggggggicon_rolleyes.gif

    Santa Monica blvd in gay WeHo, there are no yellow flashers when people try to cross the street, must drive terribly slow in this area for fear of a drunken partier darting out onto the blvd

    Make sure we check these streets for light sync, traffic most horrible

    La Cienega
    La Brea
    Robertson
    Pico
    Olympic
    Veince
    Wilshire
    Western
    Highland
    Fairfax

    that's too broad, parts of the 405 can be your friend. it's like other things in life, you just need to know when to get on and when to get off.

    oh and @scruffLA left Franklin off his list, though maybe he was concentrating on weho, he's right about olympic & fairfax, though there's some hotels and apt buildings that have drives behind that connect to two through streets, and can be useful for getting around traffic light backups.

    and people, stay away from hillhurst please.

    Fountain was also most useful if you're coming off the SB 101. I'd sometimes go out to homo town on the way home from Bob's in Toluca Lake. Made for a nice contrast betweem the super friendly red neck car buddies at Bob's and the attitude queens in WeHo. I'd park in the PDC and the car wold be as safe as it could be anywhere and then out to MIckey's for a few.

    Or if the PDC was closed for a special event, I'd park in Beverly Center, and on the 5th floor of the parking garage there was one space protected by poles on three sides so no one could park beside me. I really never had a worry about protecting the car contrary to what most folks would think about LA.
