Developing System for Consistent Messaging on Interstate 80's Dynamic Message Signs - Phase 1 (Mar. 2009, MPC-09-211A, Project #286)
Michelle Edwards and Rhonda Young
This study will analyze the effectiveness of traveler information, with a focus on the use of DMSs on the I-80 corridor between Laramie and Cheyenne in southeast Wyoming, using several methods including evaluation of the consistency of past DMS messages, surveys of both frequent and random travelers, and statistical analyses of the correlation between speed, weather, and DMS data. The current message decision system utilized by the Wyoming Department of Transportation (WYDOT) will also be described and evaluated. A framework for future development of an advanced decision support system using real-time speed and weather data will be discussed along with suggested modifications to the current traveler information system to improve its effectiveness in the short term.

| Traffic Safety Vulnerability Information Platform for Highways in Mountainous Areas Using Geospatial Multimedia Technology (Dec. 2008, MPC-08-209, Project #292)
Suren Chen, Juhua Liu, Feng Chen, and Jun Wu
An integrated mobile testing study that utilized a large truck equipped with various testing equipment was conducted on Interstate I-70 in Colorado. The field study integrated wind measurement, vehicle dynamic monitoring and geospatial multimedia technology on a real-time and synchronized basis. Essential multi-type data was collected in both time and spatial domains for further investigations of wind characterizations and the safety performance of large trucks under crosswinds, in complicated topographic conditions and other environmental conditions. Environmental geospatial multimedia information for transportation safety has become a very important information source with data integration from both DOT and drivers' perspective in terms of planning, precise decision-making and management. Drivers can benefit from the geospatial multimedia information of road environments in terms of driving safety and confidence. Based on the field testing results, a framework for a traffic vulnerable information system was developed, and the geospatial multimedia technology was integrated with environmental condition and just emerged in transportation engineering field and Web-based platform to assist transportation management and drivers. This study implemented Video Mapping System (VMS) technology along the I-70 mountain corridor, measured wind speeds in three dimensions and accelerations in two dimensions, and developed a Web-based geospatial multimedia database with embedded wind speeds and accelerations as environmental-related georeferenced vulnerable traffic information at selected feature points in the testing route.

| Design/Build vs. Traditional Construction User Delay Modeling: An Evaluation of the Cost Effectiveness of Innovative Construction Methods for New Construction: Part 2 (May 2007, MPC-07-187B, Project #265)
Peter T. Martin, Aleksandar Stevanovic, Ivana Vladisavljevic, and Dejan Jovanovic
This paper presents preliminary results of the VISUM Online validation. It compares traffic conditions estimated by VISUM Online to measured data. The results show that VISUM Online produces comparable traffic measures.
