If you are going to pay presumably a lot more money for all of the extra detectors and electronics then they need to deliver 2 things as mentioned by OP: 1) They make sure that anyone on the crossing has time to cross rather than stopping traffic for a fixed amount of time (useful outside schools) and 2) If there aren't any people crossing, the traffic should be stopped for a short amount of time no worse than if they were just a normal Pelican crossing.
However.
Even when no-one is crossing or in some case someone crossed and is about 50 metres up the road, the crossings are still usually on red for a total of often 20 seconds, which is way longer than most Pelican crossings that are on red for usually 5 to 10 seconds max.
I don't know if no-one notices or cares but it is really annoying!
Thanks for the project write up and shaking up the Halloween costume mix a little.
Thanks a lot, glad you enjoyed!
In my neighborhood there’s one at a two lane road but the street itself is very wide so people generally drive very fast to begin with and are often distracted.
Lots of conflict at that crossing even with LED flashers. I don’t know what to do to make drivers pay attention to the strip of road right in front of them.
I’ve seen roads in Japan where the lines marking car lanes narrow as you approach crosswalks, creating the impression of an environment where drivers should slow down.
The battery provides approx 6V - the timing circuit uses a 555 IC to create a pulsed signal. The combination of resistor and capacitor values determines the period of oscillation. Then, the output signal from this circuit is used to switch a transistor on and off. That makes/breaks a connection from the battery to the LED strings.
I also added a switch to select between the red LED and Yellow LED strings.
Will draw the final circuit if I get some time :)
What does this mean?
A type C Zebra crossing is one that doesn't have the Belisha Beacon lights at either side. Rare now but it existed before that innovation.
> The MINISTER of TRANSPORT (Mr.Hore-Belisha) The present arrangements are experimental, and I am watching them closely with a view to making such alterations as experience may show to be desirable in the interests of public safety.

I think "controlled" means drivers are legally obliged to stop to let pedestrians cross.
I've done freeform electronics before, using wiring that was mainly the snipped-off legs of through hole resistors. I guess if you were fancy you could buy some bus wire. The assemblies are horrific to look at, and I love them.

This was surplus sheet. Doesn't scale, but fits the reduce/reuse/recycle model well, 2nd mode.
If that's a problem... then just don't do it? Turn on RY only after you show R to walkers
I don't see the point for a total redesign
Firefox does, including on mobile platforms.
