More than half of fatal traffic crashes occur due to aggressive driving according to AAA (American Automobile Association) Foundation for Traffic Safety. Ubiquitous technology has made it possible to monitor driver behavior at a high frequency for a long period of time. This provides an opportunity for researchers to investigate risky driving behavior at a large scale. This project aims to develop a big data analytics framework and visualization tool to conduct spatiotemporal modeling and classify and visualize aggressive driving behavior using data from emerging technology. As an essential safety planning tool in the era of big data, this framework/tool can be used to identify where and when aggressive driving occurs. The Safety Pilot Model Deployment (SPMD) data, one of large transportation datasets available via the FHWA Research Data Exchange (RDE) program will be used as a big data example. A classification model will be developed to discriminate aggressive driving from normal driving using kinetic and environmental GIS data. Web-based data visualization tools will also be developed to identify the spatial and temporal distribution of aggressive driving. Furthermore, data visualization in a simulated real-time scenario will be conducted to produce insights from future transportation data considering the anticipated widespread adoption of autonomous and connected vehicle technology.
Course Slides GEOG 594 (pptx): The project contributed to Big Data Science and Analytics Platforms (GEOG-594), taught by Dr. Dr. Ming-Hsiang Tsou during Fall 2018 and again in Fall 2019. The Safe-D project was introduced in the week 2 lecture (What is Big Data?). A dataset from this project is listed as one potential group project topic. One student used the GPS dataset and ArcGIS Insights for a technical demo.
Course Slides – GEOG 580 (pptx): The project contributed to Data Management for GIS (GEOG-580), taught by Dr. Atsushi Nara during Fall 2018 and again in Spring 2020. The Safe-D project and its database design using the E-R (Entity-Relationship) diagram were introduced.
Classification Model Demo: Project developed a ‘classification model that distinguishes aggressive driving from normal driving’
The project team had a booth display and technology demonstration of Safe-D projects, including the current one, on March 17, 2018, for SDSU Explore Day event at San Diego State University (https://admissions.sdsu.edu/tours_events/explore).
Web-based tools were developed to visualize where and when risky driving occurred as follows:
