A major strategy of federal ITS initiatives and state departments of transportation is to provide traveler information to motorists through various means, including variable message signs, the internet, telephone services like 511, in-vehicle guidance systems, and TV and radio reports. This is...

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...

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...

The assumption that the penalty for being early is less than that for being late was put forward by Vickrey (1963) who analyzed how commuters compare penalties in the form of schedule delay (due to peak hour congestion), against penalties in the form of reaching their destination (ahead or...

This paper analyzes the distribution of travel time across different classes of roads for 47 subjects in the Minneapolis-St. Paul metropolitan area. We use global positioning system (GPS) and geographic information system (GIS) data to analyze subject road use, with the objective of getting a...

Additional highway capacity, by increasing travel speed, affects the individual share of time within a 24-hour budget allocated to various activities (time spent at and traveling to home, shop, work and other). Some activities will be undertaken more, others less. This paper extends previous...
