Development Of Intelligent Multimodal Traffic Monitoring Using Radar Sensor At Intersections, Siyang Cao, Yao-Jan Wu, Feng Jin
Development Of Intelligent Multimodal Traffic Monitoring Using Radar Sensor At Intersections, Siyang Cao, Yao-Jan Wu, Feng Jin
TREC Final Reports
Multimodal traffic monitoring is critical for improving mobility and safety at intersections with potential conflicts among various modes of transportation. Traditional traffic monitoring approaches utilizing cameras cannot work reliably during the night and under hazardous weather conditions. We propose to build a new intelligent multimodal traffic monitoring device using the low-cost mmWave radar. The proposed device can reliably distinguish different modes (such as buses, pedestrians, bicyclists, trucks, motorcycles, etc.), and determine the counts, speed, and moving directions of every single target in an urban environment under various lighting and weather conditions. In the study, a low-cost prototype system will also …

TREC Final Reports
Multimodal transportation systems (e.g., walking, cycling, automobile, public transit, etc.) are effective in increasing people’s travel flexibility, reducing congestion, and improving safety. Therefore, it is critical to understand what factors would affect people’s mode choices. With advanced technology, such as connected and automated vehicles, cities are now facing a transition from traditional urban planning to developing smart cities. To support multimodal transportation management, this study will serve as a bridge to connect speed management strategies of conventional corridors to connected vehicle corridors. This study consists of three main components. In the first component, the impact of speed management strategies along …
Improved Pedestrian Safety At Signalized Intersections Operating The Flashing Yellow Arrow, David Hurwitz, Christopher M. Monsere
Improved Pedestrian Safety At Signalized Intersections Operating The Flashing Yellow Arrow, David Hurwitz, Christopher M. Monsere
TREC Final Reports
In some jurisdictions, protected left-turn phasing has been replaced with the flashing yellow arrow (FYA) for protected/permissive left turns (PPLTs) to reduce delay. However, it is important to have a thorough understanding of the conflict between pedestrians and the permissive left-turning vehicle. This presentation summarizes the results of research conducted with a high-fidelity, motion-based driving simulator and mobile eye-tracking equipment to study the effects of the opposing traffic, the presence and walking direction of pedestrians, and the number of section heads to display the FYA on driver performance. To accomplish this research, a six-intersection simulated environment was created. In total, …

TREC Final Reports
This project summary report describes the execution of OTREC Project #298 (Development, Deployment and Assessment of a New Educational Paradigm for Transportation Professionals and University Students). The project is one facet of a multiyear collaboration of the Region X Transportation Consortium that was sponsored by the Federal Highway Administration (FHWA). The regional collaboration aims to shift the traditional paradigm of engineering course delivery to foster a more hands-on approach. The University of Idaho, for example, has created activity-based modules for a traffic signals course, while the University of Washington developed similar modules for a freight systems course. The focus of …
