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.

    It blew my kond ehen i foind oit that engineers won’t even factor in cars when designing major bridges because they are essentially a rounding error compared to semi-trucks.

      Kinda true. Regular cars have an Equivalent Single-Axle Load (ESAL) of 0.0004. Basically, it takes about 9,600 cars to put as much wear on the pavement as one 5-axle Semi.
