Yeah I know these are used for counting vehicles but can they also be used for detecting vehicle speed?

Description: two pneumatic hoses, affixed to a road. They lead to a box that’s locked to a telephone pole. Location is southern California. On a minor artery road.

Doubtful that it’s to survey if a new stop sign is needed since the next street is minor, dead ends into this one and already has a stop sign. The next intersection with another minor artery already has a stop sign.

Extremely doubtful that a traffic light is being considered since there isn’t anywhere near the amount of traffic to justify one.

This is located on a slope. Many cars speed down here. That’s why I’m wondering about speed sensing by this device.

        We have these on bike lanes at intersections in the Netherlands.

        In addition to everything already discussed here, they also have the role of asking for a green light automatically for you. If there are no cars travelling on Street ways contending with the bike lane, the light turns green. Alternatively, it turns green when you get your turn.

        You can also ask for the green light by pushing a button, but it’s nice that some intersections (the newer ones) don’t require it.

        However, I’m not sure if these can be configured to work for both cars and bikes at the same time.

        The PDF doesn’t call them out specifically but I’m pretty sure with some work bikes could be figured out and identified. I’d be willing to be places with more bike traffic have already done that.

          I hope so. The county I live in is extremely popular for cyclists - even in the dead of winter it’s not unusual to see people riding (sometimes I’m among them, but I have my limits). It seems like it’d be useful info for the county to have.

            Agreed, and another person replied in here who sets these up that further convinces me they do. But maybe go ask that person and see what they know?
