Public transportation or operating heavy-duty vehicles can be made much safer by gathering vehicle data (from its GPS location, as well as the CAN network of the vehicle) during operation and using them in an intelligent manner such as to report near-accidents. The goal of this project is to design and implement a web interface (both desktop and mobile versions) to (1) take the data reported by a data collection system as the input, (2) display the collected data in a professional, user-friendly and intuitive manner, and (3) display the output of a data analytics engine on the collected data. Throughout this project, team will work closely with graduate students, who will be responsible for the data collection system and the data analytics engine. The developed web interface will be tested and presented to DART (Des Moines Area Regional Transit Authority).
