This report contains five chapters, each with a number of sub-sections. Chapter I presents a summary of the research findings from the Literature Review and discusses their relevance and implications for urban arterials. Chapter II discusses the theoretical underpinnings of performance measurement and various approaches in the literature. It also profiles examples of “best practice” performance measures used by forward-thinking state transportation authorities to measure multimodal and “green” aspects of transportation system performance. Chapter III describes the federal, state, and agency policies and mandates that Caltrans is subject to relative to Complete Streets and environmental quality. Chapter IV presents the proposed Complete, Green Streets Performance Measure Framework, and includes discussion and recommendations related to setting targets and data collection. Finally, Chapter V provides conclusions and proposed next steps.

The California Department of Transportation (Caltrans or “Department”) manages more than 15,000 miles of state highways, ranging in scale and function from local streets to interstate highways. Historically, Caltrans has been governed by the principles of highway engineering, which focus on providing mobility to motorized vehicles. Over the past decade, however, the Department has joined in a national movement to better incorporate non-motorized transportation and community-level outcomes into its transportation decision-making framework, embodied by the approach known as "Complete Streets." Recognizing that Caltrans’ current performance measurement system does not reflect this shift toward Complete Streets principles, researchers at the University of California, Berkeley created new measures to more accurately gauge Departmental progress toward these objectives. This paper elaborates on a proposed framework of performance measures for encouraging non-motorized transportation and increasing the environmental sustainability of the transportation system. The framework focuses on urban arterials, which carry high amounts of multimodal traffic and constitute 26% of California’s urban roadway network. Based on Complete Streets principles and the findings from an extensive literature review, the proposed framework compliments Caltrans’ current performance measurement system and presents an opportunity for the Department to become a national leader in encouraging non-motorized transportation and preserving the environment.

This paper reports on research conducted by the Safe Transportation Research and Education Center and sponsored by the California Department of Transportation (“Caltrans”) to establish performance measures for pedestrian and bicycle safety and mobility along urban arterials. Although historically focused on motorized vehicle mobility, Caltrans has recently joined in a national trend to incorporate non-motorized transportation and community-level outcomes into transportation decision-making frameworks, an approach known as "Complete Streets." Recognizing that its current performance measurement system does not reflect this shift, Caltrans worked with researchers at the University of California, Berkeley to create new measures that more accurately gauge its progress toward these objectives. This paper discusses a field test of the validity and ease of application of the proposed performance measures for pedestrian safety. The test corridor was San Pablo Avenue, a 9.5-mile, multi-jurisdictional State Route in Northern California. While the researchers developed the performance measures based on a broad literature and best-practice review, the field-test determined that most of the initial performance measures for pedestrian safety require adjustments to improve validity and facilitate their broad adoption by Caltrans. This paper demonstrates the value of small-scale field-testing of performance measures before their adoption, particularly for subject areas with little institutional measurement history, like pedestrian and bicyclist safety and mobility. The paper concludes with discussion of the next steps of the performance measures development process and future research on the topic.
