Complete streets movement is a national effort to return to traditional streets in cities to enhance livability, safely, accommodate all modes of travel, provide travel choices, ease traffic congestion, and promote healthier communities. The California Department of Transportation (Caltrans) and several local agencies in the State have developed implementation plans for complete streets. In this project, the authors developed and tested improved strategies and analysis methodologies for complete streets, taking into consideration the emerging advances in technology on control devices and...

Motorized traffic exposure and delay are two critical factors for bicycle level of service (LOS). Unfortunately, the current Highway Capacity Manual’s methodology for bicycle LOS fully accounts for neither. At the intersection level, motorized traffic speed and bicycle delay are not considered at all; and at the link level there is no account for one of the most effective traffic-exposure mitigating infrastructure types, separated bicycle lanes. This creates a systemic problem, enabling the design of roadways that ignore bicycle exposure and delay (i.e., comfort and safety), while giving...

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...

Developing quality California-specific crash modification factors (CMFs) for bicycle-related safety countermeasures will support practitioners in making more informed decisions about infrastructure improvement projects. The researchers identified a comprehensive list of countermeasures, identified existing CMFs and reviewed their quality and applicability to California, determined key bicycle injury and fatality crash patterns in the state, prioritized potential bicycle safety countermeasures for study, and identified potential study sites. The results show there is limited availability of...
