The driver seems to know that the light always takes forever and yet there he is. Sometimes people get what they deserve. 99.234.144.69 (talk) (please sign your comments with ~~~~)


when I'm at a long light like this, I don't blame the engineer of that light, I blame the city planner who decided to put that light at that intersection when a different system would have worked better (one that adjusts to time of day and/or uses sensors to notice that someone's waiting and there's no traffic). just sayin' 70.72.16.171 13:42, 25 April 2013 (UTC)

Not that 70.72.16.171 will necessarily see this, but there are traffic engineers, who design intersections (not only the types, number, and arrangement of individual signal assemblies and sensors in a given intersection, but also any timing or sensor-based relationship with other intersections and several other things not signal-related). I think the engineer in the comic is one of these traffic engineers (maybe that's what ...16.171 is calling a city planner?). It's not the one that designed the actual assembly of bulbs, lenses, circuits and housing that makes up a given "signal" - which would also no doubt be an engineer (somewhere in the civil/electrical area I might venture to guess)Brettpeirce (talk) 18:28, 18 February 2014 (UTC
I am a traffic engineer, and there are lots of reasons why intersections are designed as they are, and lots of reasons why they don't live up to expectations. Aside from the inherent difficulty of predicting traffic, there are issues centring around when the intersection was designed and when the user experiences it (this can be decades), the availability of data on the subject (in all but the densest/busiest areas most people would be surprised how little data there is, I think), and just the sheer expense of some "simple" solutions. For example, ...16.171's jurisdiction may not consider worth ~$100 000 to put in a sensor just so the occasional driver who wants to turn left from a low-volume approach only waits 20 seconds instead of 60.108.162.219.102 22:27, 26 May 2015 (UTC)

Or there's another car behind him that we can't see because of reasons of artistic brevity. -Pennpenn 108.162.249.221 04:50, 6 February 2015 (UTC)

The punchline gets funnier based on how far away you are from the forthcoming Tuesday. Only share this comic on Wednesdays. 108.162.216.71 (talk) (please sign your comments with ~~~~)
