Research Highlights

Understanding and Measuring Bicycling Behavior: A Focus on Travel Time and Route Choice

Jennifer Dill
With rates of obesity, heart disease, and related health problems increasing in the U.S., health professionals, planners, and policy makers are looking for ways to increase physical activity through changing urban form. While much of the focus is on walking, bicycling offers many benefits and warrants further research. According to the 2001 Nationwide Household Travel Survey (NHTS), over 60% of all personal trips are five miles or less in length – a reasonable distance to ride a bike – and ne... Read More

Modeling and Analyzing the Impact of Advanced Technologies on Livability and Multimodal Transportation Performance Measures in Arterial Corridors

Miguel Figliozzi
Christopher Monsere
Transit service reliability is important to both passengers and transit agencies. Slow and unreliable transit service may increase transit user costs in the short term and reduce transit mode share and ridership in the long term, which in turn may lead to higher levels of congestion, emissions, energy consumption, and car dependency in urban areas. In addition, bus travel time is important to schedulers because excessive variability forces schedulers to add excess slack or layover time to tra... Read More
