This paper reports on research conducted by the Safe Transportation Research and Education Center and sponsored by the California Department of Transportation (“Caltransâ€) to establish performance measures for pedestrian and bicycle safety and mobility along urban arterials. Although...

This study and report is about street trees and intersection safety in urban contexts. The study derives from a rather simple, straightforward observation: that on the best tree-lined streets the trees come close to the corners. They do not stop at some distance back from the intersecting street...

This paper is collaborative in every respect. Jacobs conceived of the study and was the overall director of the research. Macdonald administered the project. Detailed tasks were jointly organized and fieldwork was done by all four authors, usually in groups of two or three. Marsh and Wilson...

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...

Transportation and land use planners generally agree that high traffic volumes are incompatible with a good residential street. Danger to pedestrians and bicyclists and emissions from traffic, such as high noise levels and poor air quality, are the obvious reasons. In addition, traffic is also a...

The focus of our concern is a specific type of boulevard, the multiple roadway boulevard, which is designed to separate through traffic from local traffic. It consists of a central roadway, generally at least four lanes wide and used for fast and non-local traffic, and tree-lined medians, access...
