🛴 E-Scooter Driving Status

• In accordance with eco-friendly means of vehicle and distancing due to COVID-19
• In 2021, the number of e-scooter users increased more than 5% compared to 2019

  traffic accidents also has been increased 2.5%

• To ensure the safety of occupants and pedestrians and the safe operation of nearby vehicles
  It is necessary to crack down on compliance with electric kickboard traffic laws
• Therefore, we will create a system to monitor 'electric driving crossing of a crosswalk', which had the highest violation rate
  Source: Report on the results of a survey on the safety status of electric kickboard sharing service

🛴 Monitoring System Architecture

🛴 Traffic Violation Monitoring Proposals

Sensor-based Crosswalk road driving monitoring

• Using the webcam on the front of the scooter, verify that the scooter user passes the crosswalk
• Using a accelerometer sensor and switch sensor on the scooter footrest, it is determined whether the scooter user is driving or not
  (Absence of pressure sensor replaced by a switch sensor)
• Using the buzzer sensor inside the scooter, scooter users are warned when driving at the crosswalk
• Using GPS sensor on the front of the scooter, when a violation is determined user id, location and time infomation are send to the database

Detailed Raspberry Pi process

🛴 Traffic Violation Monitoring web server

• When the Raspberry Pi detects driving in a crosswalk, it transmits violation information consisting of the occupant ID, its longitude and latitude, and the time of violation to the database
• Violation images taken by webcam are sent to the s3 file server
• Using mysql and matplotlib, we analyze the violation status by time period, violation status by date, and users with many violations to create a graph
• Based on the data analysis result, the violation information, and the violation image, a web page was constructed, and the web server was configured using the flask server

Detailed Server operation

🛴 Expectation Effectiveness Keypoints

People - Pedestrian security

• Auto tracking system helps to detect driving violations
• Resolving the problem of shortage of enforcement personnel
• Comprehensive investigation of safety management and driving conditions

Environment - eco-friendly means of transportation

• Improved e-scooter users' awareness of safe driving
• Pedestrian safety protection
• Increased use of e-scooter using electrical energy help to be green

📑 Usage

You must download Yolov5

After downloading, you need to move crosswalk_model.py into the YOLOv5 folder.

Ada/crosswalk_hardware/main_process.py : detect driving across a crosswalk on an e-scooter
python3 main_process.py

Ada/crosswalk_model/yolov5/crosswalk_model.py : Crosswalk detected model main file
python3 crosswalk_model.py

📑 Commit Convention

Commit message consists of “Type: Subject/ Body/ Footer”

1. Type

• Feat - Added new features
• Fix - Bug fixes
• Build - Modify build related files
• Ci - Modify CI related settings
• Docs - Documentation (add, edit, delete documents)
• Style - Style (code format, add a semicolon: if there is no change in business logic)
• Refactor - code refactoring
• Test - Test (Add, modify, delete test code: if there is no change in business logic)
• Chore - Miscellaneous changes (modify build scripts, etc.)

2. Subject

• The title should not exceed 50 characters and should not include periods.
• In the title, write the commit type together.
• Write in imperative without using the past tense.
• The title and body are separated by a single space.
• The first letter of the title must be capitalized.
• You must include the issue number (if any) in the title or body.

3. Body

• As it is optional, it is not necessary to write the body of every commit.
• No more than 72 characters per line.
• Write according to what and why rather than how.
• It is used not only for explanation, but also when writing the reason for commit.

4. Footer

• It's optional, so you don't have to put a footer on every commit.
• Used when creating an issue tracker ID.
• Resolution: Used to resolve issues
• Relevant: Issue number related to the commit
• Note: Used when there is an issue to refer to
