Bicycling

Adult bicycle education classes are becoming an increasingly popular strategy to improve safety, mitigate congestion, and reach environmental goals. However, there is limited empirical research on the effectiveness of these classes among adults, and there are no studies evaluating the impacts of classroom-based education on this population. To address this gap in knowledge, a study was conducted evaluating the effectiveness of classroom-based adult bicycle education on delivering changes related to bicycling activity, self-perceptions while bicycling, knowledge of the bicycling rules of...

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...

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...
