  Citation × Citation Citation Abstract Copy Title: Webinar, Part II: Four Types of Cyclists: A National Look Author: Dill, Jennifer Year: 2015 Originally developed by Roger Geller for the city of Portland, the "Four Types of Cyclists" typology (Strong and Fearless; Enthused and Confident; Interested but Concerned; No Way No How) has been adopted widely to help guide efforts to increase bicycling for transportation. This webinar will present findings from a new, national survey conducted in collaboration with the National Association of Realtors. We will address the following questions: Does the Four Types of Cyclists typology apply nationally? What are the characteristics of each type of cyclist? How does the existing environment, including bicycle infrastructure, affect the share of people in each category/type? What programs or infrastructure might increase bicycling for transportation among the different types of cyclists?

  Citation × Citation Citation Abstract Copy Title: A Level-of-Service Model for Protected Bike Lanes Author: Foster, Nick, Monsere, Christopher, Dill, Jennifer, Clifton, Kelly Year: 2015 Several methods exist for quantifying the quality of service provided by a roadway from a bicyclist’s perspective; however, many of these models do not consider physically protected bike lanes and, of those that do, none is based on empirical data from the US. This is problematic as engineers, planners, and elected officials are increasingly looking to objective performance measures to help guide transportation project design and funding prioritization decisions. This paper addresses this gap by presenting a cumulative logistic model to predict user comfort on protected bike lanes developed from data collected during in-person video surveys. The surveys were conducted in Portland, OR with video footage gathered in Chicago, IL, Portland, OR and San Francisco, CA. The model is for road segments only and not signalized intersections. It complements the Highway Capacity Manual 2010 level-of- service methods by providing an analysis procedure for a facility type that is not currently included in the manual. The model indicates that the type of buffer, direction of travel (one-way vs. two-way), adjacent motor vehicle speed limit, and average daily motor vehicle volumes are all significant predictors of bicyclist comfort in protected bike lanes. The model predicts a mean value of ‘A’ or ‘B’ on an A (most comfortable) – F (least comfortable) scale for all protected bike lane clips used in the survey. Consistent with previous research findings, survey respondents report that protected bike lanes are generally more comfortable than other types of on-street infrastructure.

  Citation × Citation Citation Abstract Copy Title: Peer-To-Peer Carsharing: Short-Term Effects on Travel Behavior in Portland, OR Author: Dill, Jennifer, McNeil, Nathan, Howland, Steven Year: 2017 Peer-to-peer (P2P) carsharing is a relatively new concept in the U.S. Enabled by recent internet and mobile technology development, P2P carsharing generally involves a facilitating company connecting private vehicle owners to people who are interested in renting a vehicle. P2P carsharing has many things in common with business-to-consumer (B2C) carsharing services. Consumers join the service to rent vehicles on a short-term basis from locations dispersed throughout a certain area. Both services may allow households to reduce their private car ownership. However, P2P carsharing differs substantially from other models in that there are two distinct sets of consumers: those who rent the vehicles (renters) and those who put their vehicles up for rent (owners). The members of the service are providing the supply as well as the demand. Not only does the car owner provide the vehicle and determine where it is parked, they determine what hours it is available for rent and at what price (though with some influence from the facilitating company). This report presents findings from a multiyear study of P2P carsharing that began in early 2012 and targeted members of Getaround, which launched in February 2012 in Portland, OR. The goal of this study, which collected information from both owners and renters, is to evaluate the impact of peer-to-peer carsharing relative to other models of car use, including ownership, rental, and conventional (corporate) carsharing. The two primary research questions are whether P2P carsharing can reduce overall and peak- period vehicle miles traveled (VMT) by marginalizing the cost of driving, and whether P2P carsharing increases access to jobs and other activities for those without cars. Compared with conventional carsharing, P2P carsharing has the potential to influence VMT for both the renter and the owner. P2P owners may reduce their driving so that the vehicle is available for rent. Renters, as with other forms of carsharing, may decide to forgo or reduce vehicle ownership and drive less because the marginal costs of driving are more apparent. This report also examines motivations and factors associated with greater or lesser participation (in terms of rental activity), the influence of P2P carsharing on travel behavior and attitudes toward car ownership, and general experiences with P2P carsharing Title: Peer-To-Peer Carsharing: Short-Term Effects on Travel Behavior in Portland, OR Author: Dill, Jennifer, McNeil, Nathan, Howland, Steven Year: 2017 Peer-to-peer (P2P) carsharing is a relatively new concept in the U.S. Enabled by recent internet and mobile technology development, P2P carsharing generally involves a facilitating company connecting private vehicle owners to people who are interested in renting a vehicle.
