Differences Between Walking and Bicycling Over Time: Implications for Performance Measurement

Schoner, Jessica E.; Lindsey, Greg; Levinson, David - Networks, Economics and Urban Systems Research Group … - 2014

Transportation policies and plans encourage non-motorized transportation and the establishment of performance measures to assess progress towards multi-modal system goals. Challenges in fostering walking and bicycling include the lack of data for measuring rates of walking and bicycling over...

The missing link: bicycle infrastructure networks and ridership in 74 US cities

Schoner, Jessica; Levinson, David - In: Transportation 41 (2014) 6, pp. 1187-1204

Cities promote strong bicycle networks to support and encourage bicycle commuting. However, the application of network … planners and policymakers to evaluate their local bicycle facility networks and set regional priorities that support …

Accessibility and the choice of network investments in the London Underground

Levinson, David; Giacomin, David; Badsey-Ellis, Antony - Networks, Economics and Urban Systems Research Group … - 2014

In 1863, the Metropolitan Railway of what came to be known as the London Underground successfully opened as the worldâ€™s first subway. Its high ridership spawned interest in additional links. Entrepreneurs secured funding and then proposed new lines to Parliament for approval, though only...

People are not â€˜rationalâ€™: An empirical study of the deviation between actual and shortest travel time paths

Tang, Wenyun; Levinson, David - Networks, Economics and Urban Systems Research Group … - 2014

Few empirical studies of revealed route characteristics have been reported in the literature. This study challenges the widely applied shortest path assumption by evaluating routes followed by residents of the Minneapolis - St. Paul metropolitan area, as measured by the GPS Component of the 2011...

The Weakest Link: A Model of the Decline of Surface Transportation Networks

Xie, Feng; Levinson, David - Networks, Economics and Urban Systems Research Group … - 2007

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...

Measuring the Structure of Road Networks

Xie, Feng; Levinson, David - Networks, Economics and Urban Systems Research Group … - 2005

Spatial networks display both topologic and geometric variations in their structure. This study investigates the …. Proposed measures were applied to 16 test networks, which were derived from 4 idealized base networks: 90-degree, 45-degree, 30 …-degree, and completely connected. The results show that the differentiated structures of road networks can be evaluated by …

Indifference Bands for Route Switching

Di, Xuan; Liu, Henry X.; Zhu, Shanjiang; Levinson, David - Networks, Economics and Urban Systems Research Group … - 2014

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...

Alternative High Occupancy/Toll Lane Pricing Strategies and their Effect on Market Share

Janson, Michael; Levinson, David - Networks, Economics and Urban Systems Research Group … - 2014

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...
