This paper examines Columbia, Maryland, called "The Next America" by its founders in 1967. It compares the planning goals and actual achievements over the third of a century that the city has existed. The physical plan and social plan are discussed in turn, and their reinforcing aspects...

WThis research investigates how land use and road network structure influence home-based single-destination choice in the context of trip chains, using the in-vehicle GPS travel data in the Minneapolis-St. Paul Metropolitan area. We propose a new choice set formation approach which combines...

Based on in-vehicle GPS travel data in the Minneapolis - St. Paul Metropolitan Area, this research investigates how land use, road network structure, and route fa- miliarity influence home-based single-destination choice. We propose a new choice set formation approach which combines survival...

The concept of "accessibility" has been coin in the transportation planning field for more than 40 years. Improving accessibility is a common element in the goals section in almost all transportation plans in the US. In this study we compare the changes in levels of accessibility over time in...

In an urban context people travel between places of residence and work destinations via transportation networks. Transportation studies that involve measurements of distances between residence and work locations tend to use Euclidean distances rather than Network distances. This is due to the...

This paper explores impacts of ramp metering on urban land use. A regression-based transportation model is developed to capture changes in accessibility caused by ramp metering on a highway network. A Land Use Change Indicator (LUCI) model is modified to estimate how the spatial distribution of...

A model to examine the choice by jurisdiction whether to finance roads with taxes or tolls is developed. The idea of decentralized, local control and multiple jurisdictions distinguishes this analysis from one where a central authority maximizes global welfare. Key factors posited to explain the...

This study analyzes the effect of accessibility to jobs and houses at both the home and work ends of trips on commuting duration for respondents to a household travel survey in metropolitan Washington, DC. A model is constructed to estimate the effects of demographics and relative location on...

This paper reviews the state of high-speed rail (HSR) planning in the United States c. 2010. The plans generally call for a set of barely inter-connected hub-and-spoke networks. The evidence from US transit systems shows that lines have two major impacts. There are positive accessibility...

Roads cover a signiÞcant fraction of the land area in many municipalities. The public provision of roads means this land is exempt from the local property tax. Transferring roads from public to private ownership would not only remove maintenance costs from city budgets, but increase potential...
