What are those cables across the road?

They measure the number of vehicles over a 24-hour period. At times, two parallel cables are deployed. That enables the DOT to determine the speed and type of vehicle (car, bus, or 18-wheel truck). The two-tube counters, also known as Continuous Count Stations (CCS), count vehicles 24 hours a day, 7 days a week.

What are the two rubber strips across the road?

Shoulder and centerline rumble strips are used to reduce lane departure crashes. Centerline rumble strips are used on undivided highways to reduce cross-over incidents and resultant head-on collisions. Shoulder rumble strips are used primarily to reduce run-off-road collisions.

How do road counters work?

Pneumatic road tube sensors send a burst of air pressure along a rubber tube when a vehicle’s tires pass over the tube. The pressure pulse closes an air switch, producing an electrical signal that is transmitted to a counter or analysis software.

What are the two black hoses across the road?

They look like a black hose strung across the road. Department of Transportation officials said they are tube or hose counters. Each time a car compresses the tube, the air sends a pulse to a counter and records the information. The tubes or hoses measure traffic volume and provide information for planning purposes.

What is the black rope on the road?

According to Jalopnik, those mysterious rubber cords are officially known as pneumatic road tubes. The technology they use is simple. Every time a vehicle’s tires hit the tube, it sends a burst of air that triggers a switch, which then produces an electrical signal that’s recorded by a counter device.5 មេសា 2018

When turning left you must yield the right away to?

Drivers turning left must yield to oncoming vehicles going straight.
