Federal Aid and Rural County Highway Spending: A Review of the 1980

The Reagan/Bush Administrations cut back federal support for state and local governments during the 1980s, causing total real resources available to finance local roads and bridges to increase very slowly between 1977 and 1989. The effect of federal aid on spending for infrastructure has been subject to debate for many years. Some studies have indicated that federal aid is stimulative, while others report that federal aid substitutes for local resources. This article examines the effect of state and federal aid on county highway spending. The analysis demonstrates that, in 1987, federal aid was stimulative but state aid was not. In light of changes brought about by the Surface Transportation Efficiency Act of 1991 (ISTEA), we can expect federal aid to have a stronger relationship with local highway spending.     

A Measure of Competitive Access to Destinations for Comparing Across Multiple Study Regions

Accessibility is now a common way to measure the benefits provided by transportation–land use systems. Despite its widespread use, few measurement options allow for the comparison of accessibility across multiple urban systems, and most do not adequately control for market competition between demand-side actors and supply-side facilities in localized markets. In this article, we develop a measure of competitive access to destinations that can be used to accurately compare accessibility between regions. This measure stems from spatial interaction modeling and accounts for competition at both the supply and demand sides of analysis, regional differences in transportation networks and travel behavior, and any imbalance between the size of the population and the number of opportunities. We use this method to compute access to employment for Canada's eight largest cities to comparatively examine inequalities in accessibility, both within and between cities, and by travel mode.     

When Survey Goes East: Field Survey Methodologies and Analytical Frameworks in a Central Asian Context

This paper investigates the applicability and transferability of conventional frameworks of archaeological survey in the context of marginal alluvial environments, particularly the unique inland deltas of Central Asia. These dynamic and visually obstructed landscapes pose unique challenges not only to survey methodologies but also to theory and interpretation. Here, an exploratory approach to data analysis is used that applies three distinct yet integrated methodologies: visibility analysis, multi-scalar spatial analysis and directional (anisotropic) statistics. This approach thereby moves beyond many of the existing conceptual constraints about how we understand surface distributions in arid alluvial landscapes and ultimately identifies both transferable analytical methods and new fieldwork agendas that are relevant to a wide range of survey projects.
