Our Projects

On our campus and the surrounding roads, the degree of road damaging will be different every year. Traditionally, the department of transportation uses a huge detection car to detect road damage. Our client Dr. Ho finds that it was not only cumbersome, but also only applicable to motor vehicles, and it is expensive. Hence, the goal of our team is to finish the same function based on bikes. However, compared to the huge detection car, our devices have more advantages: it costs less, applies to any road, and is more portable.

The basic components consist of a camera, an accelerometer, the Global Positioning System (GPS), the Android mobile application development, and data analysis. The accelerometers will save three-dimensional data, the camera will show real-time videos of the roads as a reference, and the GPS will record the location information of the bumps. As for the App, we determine to design one for the Android system with a humanized user interface.

In terms of the data sharing, we use Wi-Fi and wireless mesh network (WMN) to share the information with other users. Finally, our test routes mainly focus on bike lanes on campus, which helps us to amend our design scheme based on the results of each experiment.

Project Dipiction

Communication between sensor and Raspberry Pi

Allowing smooth transition between Linux and Raspberry Pi

Collecting sets of data for analyzation of dynamic threshold and terrain recognition algorithm.

Ex: Biking around campus based on weather conditions

Wet, Snow, Dry, etc.

Process collected data from accelerometer and camera and provide feedback for users’ route plan decision making

Recognize the terrain’s type by images and machine learning algorithm.

Test

Due to COVID 19 our test is mainly about the data we collected

here is what we got from the test

  • the thresholds under wet condition are generally slightly lower than the thresholds under dry condition.
  • the thresholds under snowy condition are obviously higher than the thresholds under dry condition.
  • in Asphalt Concrete and Grass conditions, the thresholds of the mountain bike are lower than the thresholds of the street bike.
  • in the dirt roads, the mountain bike’s thresholds are higher than the street bike’s thresholds.
  • you can see more detail abput our test in our paper which is in the final project
