2:00 - 2:25 Pam Murray-Tuite (VT): “Winter Weather Demand Considerations for Network Performance Predictions.”

The 2013-2014 winter was particularly harsh for the US’ east coast.  Snow storms and below freezing temperatures caused disruptions to school and employer schedules and had potentially severe traffic implications.  For example, Atlanta, GA experienced gridlock when schools and employers released students/employees early in a low accumulation snow storm.  These traffic conditions, combined with low temperatures, emphasize the need to be properly prepared for winter weather and to better understand how travelers will react to different winter weather conditions and school and employer decisions.  Part of the study of travelers’ reactions includes what changes they may make in their trips, e.g., cancelling trips, adding trips, changing trip timing, changing transportation modes, changing routes, and changing the type of road primarily used (highway/arterial).  This webinar explores changes in traveler behavior, and factors associated with those changes, in the Northern Virginia area based on a behavioral intention survey.  Understanding the potential changes can allow state and local departments of transportation to better prepare for the changes and treat the roads in accordance with anticipated behavior as well as established priorities.

2:25 - 2:45 Discussion

2:45 - 3:10
Hesham Rakha/John Sangster (VT): “Development of Methodologies for Alternative Intersection Analysis.”

Alternative intersections have unique geometries that theoretically lead to improvements in safety and arterial throughput.  Widespread adoption of these designs has been slow, due in part to the lack of delay-based analysis methodologies for use in preliminary engineering.  Comparative analysis of these geometries previously required microsimulation of each alternative, until FHWA provided a capacity-based spreadsheet tool in 2011, the Capacity Analysis for the Planning of Junctions (CAP-X) program.  While the CAP-X tool provides a low-cost and easy to use software for the preliminary engineering stages of a project, the comparative results of this tool have yet to be shown to scale-up to delay-based comparative analysis.  If the tool indicates that designs x, y, and z perform best from a capacity perspective, there is no guarantee that x, y, and z will correspondingly perform best from a delay perspective.

3:10 - 3:30 Discussion
