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 …

Data-Driven Mobility Strategies For Multimodal Transportation, Yao-Jan Wu, Xianfeng Terry Yang, Sirisha Kothuri, Abolfazl Karimpour, Qinzheng Wang, Jason Anderson

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 …

Influence Of Road Cross Section On Access Spacing, Karen K. Dixon, Yanfen Zhou, J. L. Gattis

TREC Final Reports

This report presents a study on the influences of select cross-sectional-related design elements (specifically median configurations and bicycle lanes) and their impact on crash severity and type, as well as the associated driver gap acceptance for turning maneuvers at midblock driveway locations on urban arterials. The primary goal of this proposed research is to better understand how the median and bicycle lane configurations can influence safety and operations at driveway locations. The research team utilized crash data, traffic data, and roadway information from driveway locations in the U.S. states of Oregon, Arkansas and Oklahoma. The project team supplemented the data …

Bicycle And Pedestrian Engineering Design Curriculum Expansion, Ashley Haire

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 …

Bicycle And Pedestrian Design Curriculum Expansion, Lynn Weigand

TREC Final Reports

This project broadened course offerings on bicycle and pedestrian transportation by redesigning and expanding an existing, three credit undergraduate/graduate course into a five-credit course that includes an applied lab component. The course was open to graduate and undergraduate students in planning and engineering programs. The PI (Lynn Weigand, Ph.D., adjunct faculty) and Mia Birk, adjunct faculty course instructor, developed the course with the following learning objectives:

• learn principles of bicycle and pedestrian facility design;
• understand integration of bicycle and pedestrian facilities within the right-of-way;
• understand basic transportation research and data collection methods; and
• apply course content through project work.

The …
