OVERVIEW
Intelligent transportation systems (ITS) change our communities by improving the safety and convenience of people’s daily mobility. The system relies on multimodal traffic monitoring, that needs to provide reliable, efficient and detailed traffic information for traffic safety and planning. How to reliably and intelligently monitor intersection traffic with multimodal information is one of the most critical topics in intelligent transportation research.
In multimodal traffic monitoring, we gather traffic statistics for distinct transportation modes, such as pedestrians, cars and bicycles, in order to analyze and improve people’s daily mobility in terms of safety and convenience.
In this study, we use a high-resolution millimeter-wave (mmWave) radar sensor to obtain a relatively richer radar point cloud representation for a traffic monitoring scenario. Based on a new...

Speaker: Brian Saelens, Professor of Pediatrics and Psychiatry & Behavioral Sciences, Seattle’s Children’s Hospital & University of Washington
Topic: Links Between Public Transportation and Physical Activity (Effects of LRT on Physical Activity Based on Seattle GPS Study)
Summary: This seminar will explore the empirical evidence regarding the links between the use of public transportation and physical activity, with a specific focus on using integrated device and self-report methods to identify travel modes and physical activity.
Bio: Brian E. Saelens, Ph.D. is a Professor of Pediatrics and Psychiatry & Behavioral Sciences at the University of Washington and Principal Investigator at Seattle Children’s Research Institute. Dr. Saelens is a clinical/health psychologist. His interest areas include obesity treatment and prevention, especially in environmental factors and policies that influence physical activity and eating behaviors in children and adults. He has published over 150 peer-reviewed original investigation and review articles.

Learn from experts and share your knowledge of how to count pedestrians. Are people with clipboards the only way? What technologies work and how can we use them? How can an agency improve an existing or start a new pedestrian count program? Join us for an information sharing webinar on this quickly evolving topic. We will learn from leaders in the field and encourage active audience involvement, so come prepared to share your experience!
This IBPI webinar is part of a project sponsored by FHWA to study best practices in pedestrian traffic monitoring.
Portland State University is working with ICF International and Sprinkle Consulting on a contract to the U.S. Department of Transportation, Federal Highway Administration to advise them on potential improvements to the Traffic Monitoring Guide specific to pedestrian travel.
Featuring:
- David Jones of the Federal Highway Administration will introduce the topic and...

Joseph Broach, PhD candidate in Urban Studies, will discuss the results of his research, which models the propensity of children aged 6-16 to walk or bike to parks and school without an adult chaperone, extending existing work on children’s active travel in several ways: 1) focus on travel without an adult, 2) inclusion of school and a non-school destinations, 3) separate walk and bike models, 4) consideration of both parent and child attitudes and perceived social norms, 5) explicit inclusion of household rules limiting walking or bicycling.
The role of walking in the development of healthy, livable communities is being increasingly recognized. In urban areas, intersections are often viewed as a deterrent to walking, as their operation primarily favors automobiles, leading to large and unnecessary delays for pedestrians. There is currently very limited research on accommodating and/or prioritizing pedestrians at signalized intersections in the North American context. Pedestrians are often considered as a deterrent to efficient vehicular traffic flow and therefore active efforts to include them in operational decisions at intersections have been lagging. This research aims to fill that gap by understanding factors that influence pedestrian crossing behavior at signalized intersections and developing cost effective and easily deployable signal timing strategies that could be employed at intersections, to increase efficiency for pedestrians.

The goal of signal timing at an intersection should be to maximize efficiency for all users. In many jurisdictions, however, traffic signals are timed mostly with the goal of reducing vehicular delay.
Other road users, such as pedestrians, deserve similar focus. In legacy transportation systems,...

Summary: Researchers from the transportation, planning and health fields share the common goal of promoting physically active lifestyle. One challenge that researchers often face is the measurement of physical activity, particularly among children. This is because the sporadic nature of children’s physical activity patterns makes it difficult to recall and quantify such activities. Additionally, children’s lower cognitive functioning compared to adults prevents them from accurately recalling their activities. This presentation will describe the design and application of a novel self-report instrument - the Graphs for Recalling Activity Time (GReAT) - for measuring children’s activity time use patterns. The instrument was applied in a study of children’s risk for obesity and diabetes in a predominately Hispanic community in Milwaukee, WI. Time-use data for two weekdays and one weekend day were collected for various physical and sedentary activities. The data was then assessed against measurements of the children’s cardiovascular fitness, weight status and insulin resistance through exploratory analysis and structured equation modeling. Findings on GReAT’s reliability and new evidence on the impacts of time-use in different activities on children’s risk for...
