Outcomes in economic evaluations, such as health utilities and costs, are products of multiple variables, often requiring complete item responses to questionnaires. Therefore, missing data are very common in cost-effectiveness analyses. Multiple imputations (MI) are predominately recommended and...

This research assesses the implications of existing trends on future network investment, comparing alternative scenarios concerning budgets and investment rules. The main scenarios compare "stated decision rules", processes encoded in flowcharts and weights developed from official documents or...

In order to maintain and improve road infrastructure in their respective jurisdictions, the state (the Minnesota DOT), region (the Metropolitan Council), and seven counties in the Twin Cities Metropolitan area develop their respective decision making (investment) processes in which federal or...

This study explores the economic mechanisms behind the decline of a surface transportation network, based on the assumption that the decline phase is a spontaneous process driven by decentralized decisions of individual travelers and privatized links. A simulation model is developed with a...

Spatial networks display both topologic and geometric variations in their structure. This study investigates the measurement of road network structure. Existing measures of heterogeneity, connectivity, accessibility, and interconnectivity are reviewed and three supplemental measures are...

This paper examines the nature of first mover advantages in the deployment of spatially-differentiated surface transport networks. The literature on first mover advantages identifies a number of sources that explain their existence. However whether those sources exist in spatial networks, and...

This paper explores drivers’ subjective value of time under moving and stopped freeway travel conditions with a stated preference survey. Unlike previous studies that assumed a constant value of time, this research relates perceived satisfaction of a freeway trip to its quality indicators....
