Using Smart Phone Location Data to Analyze Wildfire Evacuation Behavior |
The 2020 fire season has been one of the worst in decades destroying millions of acres in the western part of the United States. It has ruined homes, affected the lives of people, and destroyed natural habitats - home to a variety of flora and fauna. But what is the decision process made by those affected by wildfires in determining when and where to evacuate? Dr. Xilei Zhao, an assistant professor at UF, and her team, will be analyzing wildfire evacuation behavior by using data sources from smart phones to provide some answers. Read the full article here.

Researchers Evaluate CV Technologies & Applications Installed along Roads Surrounding UF Campus |
As part of the UFTI’s I-STREET initiative, a team of researchers at the University of Florida led by Dr. Sanjay Ranka, a Professor in the Department of Computer & Information Science & Engineering, in collaboration with the Florida Department of Transportation (FDOT), are working to evaluate connected vehicle (CV) technologies and applications installed by Siemens Mobility along four roads surrounding the UF campus in Gainesville, Florida. The technologies and applications have the potential to relieve congestion and improve safety. Read the full article here.

Researchers at UF Evaluate Cracking Performance of Asphalt Binder to Improve Testing Protocols |
Load-induced fatigue can cause cracks to form in asphalt from repeated vehicular travel. To find which properties of asphalt mixes have the potential to lead to load-induced fatigue cracking, Dr. Reynaldo Roque of the University of Florida and his team, set out to find which parameter(s) would best characterize an asphalt binder’s effectiveness in resisting load-induced fatigue cracking. Twelve asphalt mixtures based on six asphalt binders and two aggregate types were evaluated using the modified linear amplitude sweep (LAS) test and the binder fracture energy (BFE) test. Results revealed using the BFE test FED property was better indicated if following the AASHTO TP_127 standard. The LAS test was acceptable as an alternative when performed following TP 101 14. Read the final report here.

Framework for the Operational Analysis of Ramp Weaves |
The webinar will cover a completed research project aimed at identifying and improving the model for ramp weaves in the HCM. The approach is to tie the overall segment speed to that of a companion basic freeway segment, and include a speed impedance term due to weaving turbulence. The concept enables tying all freeway segment methods, and simplifies the current HCM6 procedure significantly. The proposed model is shown to fit empirical data much better than the current HCM6 model. |

Introduction to Data Analytics for Transportation |
Data offer solutions to existing transportation challenges as well as opening the door to the next generation of transportation developments. As more sensors and cameras are added to roadway infrastructure and vehicles themselves, opportunities are created for new timing and safety applications and for autonomous and connected vehicles. The amount of data involved, its processing, and its integration into existing systems requires a new toolbox of data methods. Data acquisition, management, and processing will touch every aspect of the transportation system. These methods and more are being tested and realized on the I-STREET Testbed in Gainesville, Florida, a collaboration of UFTI, the City of Gainesville, and the Florida Department of Transportation. I-STREET is a living laboratory for development of new transportation technologies that operates on City of Gainesville and University of Florida campus roadways.
