Traffic Lights
My route to work involves me stopping at a set of lights on a b-road which crosses the main A19 Selby to Doncaster road.
Always at red when I get there. I sit for 5 minutes. Lights change to let pedestrians across, then the main lights change again. I'm still sitting on red. Then a car approaches behind me, lo and behold the lights change. What gives?:confused: |
Re: Traffice Lights
induction loops in the road detect large lumps of metal like cars and change the signal pattern accordinly, bikes aren't big enough to set them off

Re: Traffice Lights
Pressure sensitive I reckon.
Is there a cross pattern of tar banding on the floor? If so, jump up & down on the pegs on approach to the solid white line, as under these lines there's a pressure sensor. Cars are heavy enough to kick the sensor in, bikes often aren't :( There's a set of lights like this near me. There's another trick that usually works. Creep slowly across the tar banding, less than 10mph. By the time you get to the lights, they've changed, and quicker than you waiting 10mins. EDIT: There is another way, but its slightly naughty & takes a little faffing to get right. Flash your headlights at just the right frequency.:smt039 EDIT2: I figured they were pressure sensative matts (since that'd be a reasonably cheap way to do things), but induction loops would work equally. |
Re: Traffice Lights
A bit of an oversight surely?
Is there anyone I can complain to? What happens if no other vehicle turns up? I'm stuck. Never had this happen to me before. Is is possible that the equipment is shoost or set up incorrectly? |

edit: if that doesn't work contact your local council's highways dept and ask them to turn up the sensitivity a bit |

the IR detectors on the top of temporary lights are they to receive a signal from a specially designed transmitter in emergency service vehicles and give them priority when approaching, nothing to do with the frequency of the flashing lights... |

I'm not suggesting that this is an approach you take on your way to work as in my case it was in the wee hours of the morning. |
Re: Traffice Lights
Just do a nice controlled stoppie on the front wheel to make sure the pressure switch is activated. Failing that, make sure the rear wheel comes thundering down so the switch thinks a tanks just moved onto it. :D

the reason people think flashing their lights works is just misperception of a chance event, your subconcious over-represents the times flashing your lights "worked" by fluke and under-represents the times it didn't when forming an opinion of whether flashing your lights works or not |
