Speed Estimation and Database Program

Grants and Contracts Details

Description

OBJECTIVES: I) Evaluate the data sources for the HERS speed model and develop a streamlined procedure to generate input data for the model; 2) Develop a methodology for estimating hourly speeds: 3) Develop a windows-based speed database program that archives various speeds, either measured or estimated, and develop a procedure to select the most appropriate one to enter into the HIS; and 4) Develop a GIS interface to display the speed map. BACKGROUND: Speed is one of the basic parameters describing traffic condition. It is used in a variety of applications such as air quality analysis and congestion performance measurement. This study builds upon the "Speed Estimation for Air Quality Analysis" and investigates several data related implementation issues. It explores the algorithms for estimating speeds at a more refined level (e.g., hourly) and establishes a windows-based program that processes and archives the speed data from various sources. The project is timely for Kentucky as KyTC expands its system of congestion performance measures as well as meets the new requirement for air quality analysis. FY 2006 ACCOMPLISHMENTS: Due to problems encountered with the original work plan, the work plan has been reworked with approval from the Kentucky Transportation Cabinet. Approval of the final work plan is pending. FY 2007 PROPOSED WORK: During fiscal year 2007 candidate projects for review will be identified for the project. Once these candidate projects have been determined, a thorough review of each project will be completed in order to determine lessons learned from the project in a project management! cost management scenario. A report will then be completed highlighting each of these projects as well as lessons that have been learned from these series of projects.
