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...

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 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 Hierarchy of Roads, the Locality of Traffic, and Governance
Zhu, Shanjiang; Levinson, David - Networks, Economics and Urban Systems Research Group … - 2011
This study investigates the usage of road networks both within and outside of home jurisdictions (city (or town) and county of residence) by analyzing GPS data collected in the Minneapolis - Saint Paul metropolitan area, which tracked volunteers’ travel behavior to determine which roads...

Travel Impacts and Adjustment Strategies of the Collapse and the Reopening of the I-35W Bridge
Zhu, Shanjiang; Tilahun, Nebiyou; Levinson, David; He, … - Networks, Economics and Urban Systems Research Group … - 2011
Major network disruptions have significant impacts on local travelers. Understanding the behavioral reactions to such incidents is crucial for traffic management and planning. This study investigates travelers' reaction to both the collapse and reopening of the I-35W Mississippi River Bridge in...

Measuring Winners and Losers from the new I-35W Mississippi River Bridge
Zhu, Shanjiang; Levinson, David; Liu, Henry - Networks, Economics and Urban Systems Research Group … - 2009
The opening of the replacement for the I-35W Mississippi River Bridge bridge on September 18th, 2008 provides a unique opportunity to evaluate the impacts generated by this additional link on network performance, and thus empirically test whether a Braess Paradox occurred. Using detailed GPS...

People don't use the shortest path
Zhu, Shanjiang; Levinson, David - Networks, Economics and Urban Systems Research Group … - 2009
Most recent route choice models, following either Random Utility Maximization or rule-based paradigm, require explicit enumeration of feasible routes. The quality of model estimation and prediction is sensitive to the appropriateness of consideration set. However, few empirical studies of...

Economics of Road Network Ownership
Zhang, Lei; Levinson, David - Networks, Economics and Urban Systems Research Group … - 2006
This paper seeks to understand the economic impact of centralized and decentralized ownership structures and their corresponding pricing and investment strategies on transportation network performance and social welfare for travelers. In a decentralized network economic system, roads are owned...

Induced Supply: A Model of Highway Network Expansion at the Microscopic Level
Levinson, David; Karamalaputi, Ramachandra - Networks, Economics and Urban Systems Research Group … - 2003
This paper examines the growth of a network based on the present conditions of the network, traffic demand, other demographic characteristics, project costs, and a budget constraint. The effects of expanding a link on its upstream and downstream neighbors, as well as on parallel links are also...

How Land Use Shapes the Evolution of Road Networks
Levinson, David; Yerra, Bhanu - Networks, Economics and Urban Systems Research Group … - 2006
The present research develops an agent-based model to treat the organization, growth, and contraction of network elements. The components model travel demand, revenue, cost, and investment. Revenue earned by links in excess of maintenance costs is invested on the link to until all revenue is...
