A study showing surprisingly high numbers of pedestrians using a congested suburban intersection draws national attention as its researchers present their findings at the annual meeting of the Transportation Research Board Jan. 11-15 in Washington, D.C. The number of pedestrians was recorded, not with a specialized counting machine, but using the technology that was already in place at the intersection.
Knowing how many travelers use a transportation system is important for a number of reasons. Engineers and planners need to be able to estimate travel demand, and to do so they typically count the vehicles. Annual average daily traffic (AADT) counts have been collected for decades in the United States.
In recent years the demand has increased for non-motorized counts. For a multi-modal transportation system it is just as essential to know the number of road users who aren’t in vehicles, but traveling by bicycle or on foot. This research offers DOTs an approach for counting these travelers that doesn’t require...Read more
OTREC at Portland State University welcomed Eva Heinen of the University of Groningen, The Netherlands, for a special seminar June 18. Around 40 people attended the presentation, held at the Intelligent Transportation Systems Laboratory and titled “Cycling in the Netherlands and Multi-Modality.”
Eva Heinen is assistant professor of infrastructure planning and mobility at the Department of Spatial Planning and Environment, Faculty of Spatial Sciences, University of Groningen. She earned a Ph.D. from Delft University of Technology in 2011 focusing on bicycle commuting.
Many people in Groningen and The Netherlands as a whole combine transit and bicycling for trips. A typical configuration involves cycling from home to a train station and then renting another bicycle to reach the final destination, Heinen said.
Few people take bicycles on transit, Heinen said, and buses don’t offer bike racks or other accommodations. Folding bikes, whose compact size allows for portability, are one exception, Heinen said. Electric-assist bikes are also popular, particularly with older people.
Heinen has published many papers on cycling in international and national journals and has a large international network in cycling. She spent three months at the University of California in Davis as a visiting scholar. She is a member of the editorial board of Rooilijn, a Dutch journal for science and policy in spatial planning; a member of the Bicycle Committee; co-chair of the...Read more
