Streetors

A data visualization project based on pedestrian data
Project Overview
Using ultra-red motion detector to count the moving average number of the pedestrian cross street on preset time, and demostrate in processing visuals
Inspiration
In the covid time, to know how many people are flowing among spaces are the key to the managers. How do we designing a tracking and data vis system can help these people easier understanding the data
The goal of this project
IoT + Data Vis Project
Jun 2016 — Jul 2017
Pedsense is a device that calculating and visualizing pedestrian traffic for moments in a day. In order to help managers count flow of people on each sidewalk for better management during pedemic.
Material used
Why use those materials
Apr 2014 - Mar 2015
Particle Argon
The board carry with a indepent wifi antana which provides a long range wifi support and it can extanded the deploying space for a lot.
IR Approximation Sensor
It detects the live singal by ultra red emission, I used it for detect how many people pass by.
P5js
A web-based enviroment which can be deploy on any server, which is the best for thoses device need long range communication.
Solar Pannel Battery Bank
Due to it is hard to find a plug on many sidewalk, self power is important toward this device. Solar power is the best solution of it, also the power bank can provide extra power during the night.
How it works
The flow
Apr 2014 - Mar 2015
Solar battery power the Argon. Appx delivering data to the board, and it send the data from most of time Wifi to the computer which process the data and visualized on p5js
The process of making the prototype
How to make it
Apr 2015 — Mar 2016
Deploying it
It is hard to deploy the device for a day without interrupt the pravicy of my neighbourhood, so I choose to recorded the data manually.
Apr 2015 — Mar 2016
Data visualization (Sketch)
Apr 2014 - Mar 2015
This version of prototype of the data vis is misleaded the user by focus on meaningless animation and unclear number indicator, also the animation consume too much power of the computer which leads the low performace while running.
Data visualization (Final)
Demo
Apr 2014 - Mar 2015
I simplied the animation and redo the level of seperation of each count which makes user easy to understand the traffic in each time period now.
How to code it
Coding explain
Apr 2014 - Mar 2015
The information of the counts are recorded in the array varible.
The Circle function and draw the arc by how many people cross the sidewalk in the time period, and it will overlay each arc to count the total number of people.
Finally the draw function exucte the Circle function.
