An Agent-based Route Choice Model
Zhu, Shanjiang; Levinson, David; Zhang, Lei - Networks, Economics and Urban Systems Research Group … - 2007
Travel demand emerges from individual decisions. These decisions, depending on individual objectives, preferences …, experiences and spatial knowledge about travel, are both heterogeneous and evolutionary. Research emerging from fields such as … road pricing and ATIS requires travel demand models that are able to consider travelers with distinct attributes (value of …

A Time Geography Approach to Understanding the Impact of Gasoline Price Changes on Traffic Safety.
Chi, Guangqing; Porter, Jeremy; Cosby, Arthur; … - Networks, Economics and Urban Systems Research Group … - 2009
The impact of gasoline price changes on traffic safety has received increasing attention in empirical studies. However, this important relationship has not been explained within a conceptual or theoretical framework. In this study, we examine this relationship within a time geography framework...

Effects of Mode Shares on Mode Choice
Carrion, Carlos; Tilahun, Nebiyou; Levinson, David - Networks, Economics and Urban Systems Research Group … - 2011
This study considers the influence of the knowledge of existing mode shares on travelers mode choice. This contrasts with traditional mode choice models, where the main objective is to predict the overall mode shares as the aggregate of individual mode choices according to variables encompassing...

I-35W Bridge Collapse: Travel Impacts and Adjustment Strategies
Tilahun, Nebiyou; Levinson, David - Networks, Economics and Urban Systems Research Group … - 2008
On August 1st, 2007, the I-35W bridge crossing the Mississippi river fell into the Mississippi river. In addition to the human tragedy that it caused, the bridge failure also impacted how people moved in the area. The bridge carried 140,000 cars daily. As such it required a significant amount of...

Gasoline Price Effects on Traffic Safety in Urban and Rural Areas: Evidence from Minnesota, 1998-2007.
Chi, Guangqing; Quddus, Mohammed; Huang, Arthur; … - Networks, Economics and Urban Systems Research Group … - 2011
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...

Network Structure and City Size
Levinson, David - Networks, Economics and Urban Systems Research Group … - 2011
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,...

A Portfolio Theory of Route Choice
Zhu, Shanjiang; Levinson, David - Networks, Economics and Urban Systems Research Group … - 2011
Although many individual route choice models have been proposed to incorporate travel time variability as a decision … single dominant route (de- fined here as a route with the shortest travel time for a 15 day period) in 18% of cases when … links travel times are correlated. This paper demonstrates that choosing a port- folio of routes could be the rational …

Accessibility Dynamics and Location Premia: Do Land Values Follow Accessibility Changes?
Iacono, Michael; Levinson, David - Networks, Economics and Urban Systems Research Group … - 2011
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...
