GPS use in travel behavior studies has seen increasing acceptance over the past decade, with more than 15 travel surveys conducted since 2000 including a GPS subcomponent. Similarly, accelerometers have become the gold standard for collecting objective physical activity data in health studies. Since 2003, GeoStats has been involved in studies that have deployed both devices in tandem to collect second-by-second travel and physical activity data never before available. This seminar will cover the use of these technologies to address key research questions facing transportation and health professionals.

Dr. Jean Wolf is the president and co-founder of GeoStats, a company specializing in the application of GPS and GIS technologies for the collection, analysis, visualization, and reporting of transportation data. Since the launch of GeoStats in 2000, Dr. Wolf has led all GPS-enhanced travel surveys and physical activity studies conducted by the firm (with more than 20 studies to date). Dr. Wolf has extensive project management, technology, and logistics experience, including 10 years at UPS as an industrial and systems engineer, which makes her uniquely qualified to run complex GPS studies that depend upon the integration of numerous processes and data flows to produce highly detailed and accurate GPS deliverables. Dr. Wolf is a member of the TRB Travel Survey Methods Committee,...

Even as Portland racks up bike-friendly honors, ongoing research at Portland State University is shedding light on a new travel option that promises to get even more people on two wheels. Electric-assist bikes, or e-bikes, could hold the key to increasing cycling, particularly among women, older adults and people with physical limitations.

Portland State researchers Jennifer Dill and John MacArthur are exploring people’s perceptions and attitudes toward e-bikes and evaluating their use to see if these bikes encourage new cyclists. This spring, they’re loaning out locally made, GPS-equipped e-bikes to 120 people to learn about people’s actual experience using the bikes, marking the first time such research has been done in the country. 

The research also includes a survey on e-bike use, which will help others understand the potential market. People who have ridden e-bikes can participate in this research by taking the survey at tinyurl.com/e-bike-survey.

E-bike use is increasing in North America, with many people switching from private cars and others using e-bikes to keep cycling as they age or after an injury. Increased use brings increased scrutiny, and efforts are already underway to limit where e-bikes can go and who can ride them. Many states require e-bike riders be licensed, set age limits or both.

Some local regulations prohibit e-bikes on bicycle and pedestrian paths. The city of Toronto,...
