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...

Traditionally, students use pencil and ruler to lay out lines and curves over contour maps for roadway geometry design. Numerous calculations of stopping sight distance, minimum turning radius, and curve alignments are required during the roadway design process in order to ensure safety, to...

Major network disruptions have significant impacts on local travelers. A good understanding of behavioral reactions to such incidents is crucial for traffic management and planning. Existing research on such topics is limited. This study investigates travelers' reaction to both the collapse and...

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...

The role of contacts on travel behavior has been getting increasing attention. This paper reports on data collected on individual’s social meetings and the choice of in-home/out-of-home meeting locations as well as the distance traveled and duration of out-home-meetings and its relationship to...

In the year 2000 Over 208,000 residents of Hennepin County, Minnesota were over the age of 55, a number that is sure to rise. This paper reports the major findings from a study conducted to assess the transportation needs of seniors residing or working in Hennepin County. The assessment is done...

This paper urges that policy decisions be based on important and reliable performance measures. Robust measures that assess the performance of the transportation and land use dimensions of cities, however, are typically missing from such discussions - they typically focus on congestion and...

In the Minneapolis-St. Paul region (Twin Cities), the Minnesota Department of Transportation (Mn- DOT) converted the Interstate 394 High Occupancy Vehicle (HOV) lanes to High Occupancy Toll (HOT) lanes (or MnPASS Express Lanes). These lanes allow single occupancy vehicles (SOV) to access the HOV...

A 2004-2006 longitudinal panel survey of I-394 residents found support levels at over 60 percent for the congestion priced High Occupancy Toll (HOT) lane, known to the Twin Cities as MnPASS. This number varies only slightly when sorted by income levels, gender, and education levels, suggesting...

Transportation analysts and the public decision-makers they support are confronted with a broad range of analytical tools for estimating the economic impacts of improvements to transportation networks. Many of the available models operate at different scales and have distinctly different...
