Much like George Lucas and the original Star Wars films, many of us may find that our passion projects are never quite finished, especially when new technology comes around or we just want to make ...

Twenty-one year old Ana Gamble sits on her black scooter at the intersection of Hull Road and Southwest Thirty Fourth Street waiting for the light to turn green. As she waits, the other traffic ...

In a bout of frustration I recently realized that the roads have all updated — most people have no idea how — and this sometimes hurts the flow of traffic. This realization happened when an ...

A traffic signal sensor in Portland. Welcome to our newest column: Bike Science with Shawn Small One of the more frustrating aspects of cycling in an urban environment is not being able to trigger a ...

Many red lights fail to detect smaller vehicles like bikes and scooters due to sensor limitations. Inductive loops, common in traffic signals, rely on sufficient metal mass to register a vehicle.

A video-detection traffic sensor system uses video cameras mounted on the mast arm of a traffic signal to "see" a vehicle approaching the intersection. When a vehicle enters the camera's "detection ...

The detector comes in both single and dual-loop versions with separate outputs for each loop. Single-loop versions have two outputs, one pulse and the other presence. Outputs in the dual-loop system ...

Download this article in PDF format. We’ve been waiting for a long time and now it’s being implemented widely—namely, artificial intelligence (AI). From automatic factories, self-driving cars and ...

It seems like engineering 101, but do you actually remember the specific differences between inductive proximity, inductive displacement, and eddy-current sensors? I asked a few friends and everyone ...

Inductive sensors are non-contact proximity sensors that detect ferrous targets, ideally ones made of mild steel thicker than one millimeter. They consist of four major components: a ferrite core with ...
