They're designed to just look unobtrusive until they're lit, otherwise you can't really see what they are. Additionally, those overhead yellow signs that say "EXPRESS LANES CLOSED- DO NOT ENTER" are usually flipped a little while before they actually close.<BR/><BR/>http://maps.google.com/maps?f=q&hl=en&geocode=&q=&layer=c&ie=UTF8&t=h&cbll=41.966673,-87.753943&panoid=wmgAeiqUFw5TYxYCqQGPAQ&cbp=2,129.59637151729356,,0,-2.1612692774518067&ll=41.974711,-87.752008&spn=0.013209,0.043259&z=15BWhttps://www.blogger.com/profile/04443995905594721900noreply@blogger.comtag:blogger.com,1999:blog-7180214205361596444.post-16447799535930217292008-05-06T08:50:00.000-05:002008-05-06T08:50:00.000-05:00Ah, see, that's a crucial piece of information!

I don't know, unfortunately. If I had to guess, they probably have sensors in the lanes leading up to the entrance, that they can use to find a clear moment to close the gates once the decision has been made to do so. Since you'd want the lanes open to the side with the heaviest traffic, they shouldn't reverse until traffic is lower, at which point they'd probably be able to find the time to close them.<BR/><BR/>That said, I mainly commented so that I'd get a notification if anyone posts the *real* answer...Eric Allix Rogershttps://www.blogger.com/profile/16986356238650409976noreply@blogger.com
