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...

This study and report was born of experience with boulevards and -- following research on the safety characteristics of such roads -- driver and pedestrian behavior on them, their physical design quantities, and existing standards and norms that effectively govern their construction, develops a...

We study the duopolistic interaction between congestible facilities that supply perfect substitutes. Firms are assumed to make sequential decisions on capacities and prices. Since the outcomes directly affect consumers’ time cost of accessing or using a facility, the capacity sharing rule...

Consider two firms, at different locations, supplying a homogenous good at constant marginal production cost. Consumers incur travel costs to the firm for each unit purchased, and the travel costs increase with the amount of travel to each firm (congestion). When all traffic and all congestion...

This paper empirically investigates the impact of airport and airline supply characteristics on the air travel choices of passengers departing from one of three San Francisco Bay area airports and arriving at one of four airports in greater Los Angeles. It does so by estimating a conditional...
