If you live in a major city, I can take a pretty good guess at one of your most common frustrations: traffic.

Firstly presented at the Student's Scientific Session of 2021, this project started like a pipe dream, Bucharest without congestions. After winning 1^st place with my dissertation, I knew I wanted to continue this endeavor, by creating a device of my own that can handle traffic volumes.

I hereby present you my project: ASL (Automated Signal Loads)

We just discussed about the paper aim, my background and the prior research the project has. Next, we shall enjoy learning about the mechanism behind the proposed project at hand.

At each approach to the intersection, there is one direction vehicles can go, called a through movement. These movements are grouped into phases of traffic signal. For example, the through movements on opposite approaches are grouped into a single phase because they can both go at the same time without conflicts.

Ideally, the green light should last at least long enough to clear the queue that built up during the red light. This isn’t always possible, especially during peak times on busy intersections.

An infrared sensor equipped with actuated control software will simply see the additional traffic and adjust its phasing accordingly. In the case where the proximity sensors malfunction, there is a backup pressure sensor embedded in the electronic board, that can feel if the discovered new car actually weights anything.
