A large literature base has found that economic factors have important effects on traffic crashes. A small but growing branch of literature also examines the role that gasoline prices play in the occurrence of traffic crashes. However, no studies have investigated the possible difference of...

Traditional "chalk and talk" teaching in civil engineering has gradually been replaced with the idea of active learning focusing on encouraging students' knowledge discovery with innovative pedagogical methods and tools. One interesting tool is the board game. This research examines the efficacy...

Network structure varies across cities. This variation may yield important knowledge about how the internal structure of the city affects its performance. This paper systematically com- pares a set of surface transportation network structure variables (connectivity, hierarchy, circuity,...

Although many individual route choice models have been proposed to incorporate travel time variability as a decision factor, they are typically still deterministic in the sense that the optimal strategy requires choosing one particular route that maximizes utility. In contrast, this study...

The structure of transportation networks and the patterns of accessibility they give rise to are an important determinant of land prices, and hence urban spatial structure. While there is ample evidence on the cross-sectional relationship between location and land value (usually measured from...

The replacement I-35W bridge in Minneapolis saw less traffic than the original bridge though it provided substantial travel time saving for many travelers. This observation cannot be explained by the classical route choice assumption that travelers always take the shortest path. Accordingly, a...

This paper discusses the development of a national public transit accessibility evaluation framework, focusing on lessons learned, data source evaluation and selection, calculation methodology, and examples of accessibility evaluation results. In both practice and in research, accessibility...

High Occupancy/Toll (HOT) Lanes typically charge a varying to single occupant vehicles (SOVs), with the toll increasing during more congested periods. The toll is usually tied to time of day or to the density of vehicles in the HOT lane. The purpose of raising the toll with congestion is to...

Using detailed travel surveys conducted by the Metropolitan Council of the Minneapolis/St Paul (Twin Cities) Region in Minnesota for 1990, 2000-2001, and 2010-2011, this paper conducts a detailed analysis of journey-to-work times, activity allocation and accessibility. This study corroborates...

Cities promote strong bicycle networks to support and encourage bicycle com- muting. However, the application of network science to bicycle facilities is not very well studied. Previous work has found relationships between the amount of bicycle infrastructure in a city and aggregate bicycle...
