In 2005, Davis, California was the first city in the U.S. to be named a Platinum-level Bicycle Friendly Community by the League of American Bicyclists. Although Davis has long been held up as a model bicycling community, where residents bike as a normal part of their daily lives, it has not been rigorously studied. Several studies underway at UC Davis are helping to fill this gap: an analysis of the history of bicycling policy in Davis; a behavioral study of factors contributing to high levels of bicycling in Davis in comparison; and an evaluation of a recent campaign to get kids to bicycle to soccer games. This presentation offers highlights from a three studies to provide a critical assessment of Davis as a bicycling community.
Susan Handy is a professor in the Department of Environmental Science and Policy and the director of the Sustainable Transportation Center at the University of California Davis. Her research focuses on the connections between land use and transportation, and she is well known for her work on the impact of neighborhood design on travel behavior. She serves on three committees of the Transportation Research Board and on the editorial boards of several journals in the fields of planning, transportation, and public health.

Some researchers have tried to categorize cyclists’ levels of traffic stress utilizing facility or traffic data that can be readily measured in the field, such as motorized travel lanes, travel speeds, and type of bicycle infrastructure.
This seminar will present data and modeling results utilizing two novel data sources:
(a) real-world, on-road measurements of physiological stress as cyclists...

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.

Abstract: The most fundamental need in a bicycling network is low-stress connectivity, that is, providing routes between people’s origins and destinations that do not require cyclists to use links that exceed their tolerance for traffic stress, and that do not involve an undue level of detour. Evaluating network connectivity therefore requires both a set of criteria for tolerable levels of traffic stress and measures of connectivity appropriate to a bikeway network.
We propose criteria by which road segments can be classified into four levels of traffic stress (LTS), corresponding to four levels of traffic tolerance in the population. LTS 1 is suitable for children; LTS 2, based on Dutch bikeway design criteria, represents the traffic stress that most adults will tolerate; LTS 3 and 4 represent greater levels of stress. As a case study, every street in San Jose, California was classified by LTS. Maps in which only lower stress links are displayed reveal a city fractured into low-stress islands separated from one another by barriers that can only be crossed using high stress links.
To measure connectivity, two points in the network are said to be connected at a given level of traffic stress if there is a path connecting them that uses only links that do not exceed that level of stress and whose length does not exceed a detour criterion (25% longer than the most direct...

Oregon, and Portland in particular, is internationally known for its love for bikes. Not only does the region have some of the highest bike ridership in the nation but the Oregon bike manufacturing industry is quickly growing as well. Oregon’s electric bike (e-bike) market is also growing, but little data are available on the potential market and e-bike user behavior and interest.
Only a limited amount of research has explored the potential new market segments for e-bikes and the economic, operational, safety, and transportation issues surrounding e-bikes in the United States. This webinar will present findings from a research project evaluating e-bike use at three Kaiser Permanente employment centers in the Portland region.
The project's primary goal was to test user...
