Active travel such as walking and bicycling can lead to health benefits through an increase in physical activity. At the same time, more active travelers breath more and so can experience high pollution inhalation rates during travel. This webinar will review the state of knowledge about how roadway and traffic characteristics impact air pollution risks for bicyclists, including the latest PSU research quantifying bicyclists' uptake of traffic-related air pollution using on-road measurements in Portland. The PSU research team including Alex Bigazzi, Jim Pankow, and Miguel Figliozzi quantified bicyclist exposure concentrations on different types of roadways, respiration responses to exertion level, and changes in blood concentrations of pollutants. Implications for planners, engineers, and policy-makers will be discussed, including guidance for more pollution-conscious bicycle network planning and design. Additionally, ways for individual travelers to reduce their air pollution risks will be discussed.
This 60-minute webinar is eligible for one hour of training which equals 1 CM or 1 PDH. NITC...Read more

During the March 2011 earthquake/ tsunami/nuclear disaster, the internet filled with stories of how something quite ordinary in Japanese life became an important lifeline—the bicycle. For example an 83-year-old woman escaped the tsunami by bicycle, and due to public-transport disruptions, bicycle stores sold out of bicycles as quickly as supermarkets sold out of food. However not just in disasters, but in daily life, the most reliable, sustainable form of transportation, next to walking, is via Japan’s estimated 80,000,000 bicycles, affectionately called mamachari.
This illustrated presentation, based on four-years of cultural-landscape research culminating the publication of世界が称賛した日本の町の秘密 (Secrets of Japanese Cities the World Admires. Tokyo: Yousensha, 2011), begins by discussing why mamachari are perfect for local transportation and the many practical ways Japanese use them. It then explores why many of Japan’s densely populated, fine-grained neighborhoods with auto-resistant narrow streets and nearby shopping, make ideal bicycle neighborhoods. Issues explored will include the mamachari’s impact on: neighborhood livability; sustainability; public health through active transportation; fostering direct human contact not possible with motor-car travel; and maintaining the compact human scale of communities by limiting transport of daily...Read more
This seminar will present results from the BikeGPS study that collected data from Portland area bicyclists using GPS technology. The study collected data from over 150 cyclists for seven days each during 2007, resulting in detailed information for over 1,500 bicycle trips throughout the urban area. The GPS data provides detailed information on the amount, location, and speed of bicycle travel and allows us to answer questions about route choice. For example, how much to people ride on roads with bike lanes, on bike boulevards, or paths? Do these patterns vary by gender, age, or other factors?

Abstract: Genesis of America's First "Platinum Bike City", Davis CA
Before there was "Portland, Bike City USA" there was "Davis, Bicycle Capital of America."
Davis and Portland are very different places. Portland is big, old, industrial. Davis is small, new, nerdy. Portland has hills and rain. Davis is flat and dry. But they are both places where people bicycle. A lot. Ordinary folks come to these cities and often start riding a bike. Bicycling in Davis began in the 1950s, when it was a tiny city with the UC agricultural campus. As the city grew, citizens demanded bicycle infrastructure. After years of negotiation, city authorities gave in to pressure and instructed their staff to begin providing for bicycles. Everything had to be designed from the ground up. America had very little bike infrastructure, but that didn't stop Davis from trying dozens of different types of lanes, paths, intersection treatments, etc., and devising workable solutions. So workable, in fact, that they became the California standard, and then the American standard. As America was adopting Davis's designs, Davis continued to promote and accomodate bicycling on many levels, and in 1980 28% of the population commuted by bike.
Now, Davis and Portland are both rated "Platinum" cities for bicycling by the League of American Bicyclists. But they're still as different as night and day. Portland...Read more

If American cities are to serve the mainstream population of traffic-intolerant bicyclists, we need a broad range of low-stress facility types that can be applied depending on traffic and space constraints. This seminar will focus on two kinds of bicycle accommodations. A “Bicycle Priority Lane” is a shared lane treatment, like the shared lane arrow or “sharrow” that is becoming popular, intended for streets lacking the space to provide a dedicated bike lane. It enhances the sharrow by providing longitudinal markings that define a “lane within a lane,” drawing from “advisory lanes” (UK) and “suggestion lanes” (NL). We show how defining the bicyclist’s space objectively with road marking frees bicyclists from the stress of negotiating for operating space with motorists.
Separated paths or cycle tracks are bike paths along a road that are physically separated from moving traffic by a curb, median, or parking lane. For decades, they have been the mainstay of bicycle networks in the Netherlands and in Montreal, but have been shunned by US planners due to misplaced safety concerns. We will expose the flaws of the studies used to discredit separated paths, and discuss their safety record in the Netherlands and in Montreal. Practical issues in cycle track design will be discussed based on Montreal’s experience of the last two decades.

The LCN+ Project Management team are responsible for improving conditions for cycling on a 900-kilometre network of London’s key commuter roads, in line with the Mayor of London’s Cycling Action Plan.
With the initial target of achieving a 200% increase in the number of cyclists in London already surpassed, the project aims to build on this by continuing to advise the 33 London boroughs on how to improve cycling infrastructure on their roads. By effectively liasing with major stakeholders such as local cycling groups, Borough Cycling Officers and Transport for London, the project can ensure that all will have agreed on the solutions reached.
Steve Cardno: Steve is the Project Manager for the London Cycle Network Plus (LCN+) project, with responsibility for the overall project management of this London wide cycling project. The LCN+ project aims to deliver 900km of high quality strategic cycle routes across London by the end of 2009/10. The project is funded by Transport for London (TfL), project managed by Camden Consultancy Services and delivered in partnership with TfL, CCS, the 33 London Boroughs and...Read more
