Abstract Large-scale bicycle network design, safety, and crash estimates largely depend on network-wide bicycling volume estimation. Previous studies developed direct demand models on a smaller scale (e.g. city or county) where bicycle count and ...Practical Applications Agencies often need to estimate bicycle volumes at the link level across entire networks for planning, safety, and design purposes. This study uses expansion factors to introduce a method for converting short-term site volume data.

Cities around the world are turning to non-motorized transport alternatives to help solve congestion and pollution issues. This paradigm shift demands on new infrastructure that serves and boosts local cycling rates. This creates the need for novel data sources, tools, and methods that allow us to identify and prioritize locations where to intervene via properly planned cycling infrastructure. Here, we define potential demand as the total trips of the population that could be supported by bicycle paths. To that end, we use information from a phone-based travel demand and the trip distance...

Why Do Building Owners Invest in Bicycle-Oriented Design?

Orrick, Phyllis
Karen Trapenberg Frick
Ragland, David R.

We found that broader government policies such as infill zoning exemptions and energy-saving directives made BOD more feasible. A comprehensive survey of existing BOD requirements, guidelines, and best practices of BOD design elements would be useful to policymakers, local officials, and developers as they confront decisions on how or if to encourage BOD. More broadly, additional research on the potential relationship between BOD and mode choice of building tenants could lead to a greater understanding of what benefits are derived from these investments as well as constraints. Finally, an...

Bicycle Infrastructure that Extends Beyond the Door: Examining Investments in Bicycle-Oriented Design Through a Qualitative Survey of Commercial Building Owners and Tenants

This paper presents the results of a qualitative survey of commercial owners, managers, and occupants in the City of Berkeley who have invested in on-site bicycle facilities such as secure parking, showers, changing rooms, and clothing lockers, what we are calling “bicycle-oriented design” (BOD). The sites represent a selection of building types common in the commercial building stock in U.S. cities.The research is designed to answer three questions about the use of BOD: (1) what were motivations behind the decision to invest in BOD (2) what are the challenges and rewards for investing in...

Airports and Bicycles: What Are Obstacles to and Incentives for Improving Bicycle Access?

2012

Case studies examined how airport operators addressed bicycle access to their properties and the motivations and obstacles that they faced in light of new policies to integrate bicycles, along with transit and walking, into transportation planning, design, and construction and to increase the bicycle's role in the transportation system. Eight influential elements that emerged from the review of policy documents and research literature were used to guide interviews: governance structure, location, access roads, self-perceived environmental stewardship, spending restrictions on nonaviation...

Airports and Bicycles: What are the Obstacles and Incentives for Operators 1 to Improve Bicycle Access?

In this paper we use a case study approach to examine how airport operators are addressing bicycle access to their properties and the motivations and obstacles they face, in light of new policies to integrate bicycles, along with transit and walking, into transportation planning, design and construction, and to increase bicycles’ role in the transportation system. Eight influential elements emerged from our review of policy documents and research literature. We used them to guide interviews with key informants. The eight elements are: governance structure, location, access roads, self-...

Exploring Bicycle and Public Transit Use by Low-Income Latino Immigrants: A Mixed-Methods Study in the San Francisco Bay Area

Barajas, Jesus

2016

Latin American immigrants will continue to make up a large share of transit ridership, bicycling and walking in the United States for the foreseeable future, but there is relatively little research about them. This mixed-methods study compares the travel patterns of low-income immigrants living in the San Francisco Bay Area with that of other groups and investigates the barriers and constraints faced by low-income immigrants when taking transit and bicycling. Much of the previous work on immigrant travel has relied on national surveys and qualitative analysis, which underrepresent...

Optimal Design of Transit Networks Fed by Shared Bikes

Transit systems are designed in which access and egress can occur via a shared-bike service. Patrons may walk to shared-bike docking stations nearest their origins, and then cycle to their nearest transit stations where they deposit the bikes. The travel pattern is reversed when patrons cycle from their final transit stations on to their destinations. Patrons choose between this option and that of solely walking to or from transit stations. Shared bikes are priced to achieve the system-optimal assignment of the two feeder options. Transit trunk-line networks are laid-out in hybrid fashion...

To Pool or Not to Pool? Understanding Opportunities, Challenges, and Equity Considerations to Expanding the Market for Pooling

On-demand mobility services such as bikesharing, scooter sharing, and transportation network companies (TNCs, also known as ridesourcing and ridehailing) are changing the way that people travel by providing dynamic, on-demand mobility that can supplement public transit and personal-vehicle use. Adoption of on-demand mobility has soared across the United States and abroad, driven by the flexibility and affordability that these services offer, particularly in urban areas where population density and land use patterns facilitate a reliable balance of supply and demand. The growth of app-based...
