Raina's Light

We basically just had to create a way to improve our school. We chose highway traffic.

1. Research

2. Survey students (both in and out of class)

How often do you get to class late?

Most people do get to class on time, however, another large portion of people gets late weekly, if not daily.

Do you take the same path every day to get to your classes?

Most people take the same path daily, some change it up a bit though.

How much do you like going to class?

Bimodal distribution, skewed right. Most dislike or tolerate it.

How frequently do you bump into people in the hallway?

Multimodal distribution, most are okay with it (and people mostly said 7, the least offensive choice).

Do you ever avoid class and instead hang out in the hallways?

Most people head straight to class, a good portion of people do hang out though.

How often do you find yourself wandering around hallways?

People usually get to class and don't wander.

How often do you find yourself getting into hallway traffic jams?

Over half of the people who responded stated that they get into traffic jams daily.

How far apart are your classes from each other?

Most people have classes a good distance from each other. We asked this because traffic jams and distance could change how late you are.

When you see a traffic light what do you think?

Most people see the majority but apparently one person thinks otherwise.

On a scale of 1-10, how crowded do you find the hallways?

Bimodal distribution, skewed left, with an outlier. Most hallways get crowded as everyone rushes from class to class.

In what order would you rank the following possible improvements?

People ranked the following improvements from best to least: First, traffic light; Second, hallway lanes/dividers; Third, Hall monitor; Fourth, strict and predetermined directions. (Sorted by majority in each column))

How would you rate this form? :)

Just a fun question, doesn't matter for the research (I also wanted to balance out the page).

3. Choosing a solution and analysis

What did we choose?

We chose to use the traffic light solution as it was most voted for and most practical for us to execute.

Data Analysis

Most people get to class late, potentially due to traffic in hallways. There are many factors, however, so it should be noted that most people followed the same route daily. A contradiction to that may be that one might have only one path to get to class.

4. Designs

The first prototype we made.

I didn't make this one, it was one of my group partners.

The second prototype we made.

I made this one mostly in Inventor 2024, and with finishing touches in 2023.

5. Materials

6. The full cad designs

7. Reflection

Traffic light reflection: first complex cad project

I like the simplicity of the original design. It is simple and unique. It also would be very easy to mass produce. On the second design (the one I did), I made it more recognizable, improved measurements (original design had very wacky and irregular measurements for things that were supposed to be equidistant [think 1.10 and 1.25 as 2 distances that were supposed to be the same but weren’t]), made dimensions unified, improved visibility, improved aesthetics, and added functionality. I would like to work on more practical things like this. One thing could be like designing parts of a moving thing or just maintaining skills. Our design is, in theory, more helpful and could control hallway traffic. If I could have made the inside hollow, I could have put electronics in it and made a working stoplight. Maybe I’ll do that one day… In reality, they might not be too helpful as most teenagers would probably just ignore it and not care enough to follow them.

Second project: Traffic Light (Likely almost done, just need some editing etc)
