South Dakota Department of Transportation
Project Synopsis

Title: Automate Traffic Data Retrieval, Editing, & Verification/Improved Load Estimates
Project Researcher: ,
Project Manager: Dan Strand
Research Period: -
Cost: $0.00

Problem Statement:The Department must have reliable traffic data. Traffic data is an important element used in decisions throughout the Department. Some decisions based upon traffic data include project selection, pavement design, safety analysis, assessment of pavement life and allocation of funds. The Office of Data Inventorys duties include the collection, management and analysis of traffic data for the Department. With the large amounts of data currently being collected through automatic traffic volume recorders and the expected increases from continuous weigh-in-motion and vehicle classification, the Office of Data Inventory needs a better system to increase productivity to accommodate the increased workload.

Current methods require manual retrieval, editing and verification which have a high potential for error. A process needs to be developed or purchased that will combine these functions into one computerized system. A new system will not eliminate operator input, but will help insure that all data are reviewed and managed as required.

Two commercial systems are available. One system (EXPERT System), available at no charge, was developed by Colorado, Kansas and Minnesota DOTs and the FHWA. This system seems to have limitations and works with continuous volume data only. The other system is marketed by Chaparral System Corporation. This software system is for the collection, editing, verification and reporting of a wide range of traffic data. The drawback with this system is its price, approximately $200,000 to $225,000 plus annual maintenance fees. It might be possible to develop an automated system in-house but it would involve a considerable amount of time and effort.

Research is needed to investigate automated systems for retrieving, editing and verifying traffic data. The end product of this project will be to recommend to the Department how best to proceed in developing or obtaining an automated system for traffic data.


Research Objectives:
1  Investigate automated systems for retrieving, editing and verifying traffic data.

Research Tasks:
1  Review the available literature on automated traffic data systems.
2  Through AASHTO Value Added Network and Internet, query other states for potential systems or advice.
3  Identify the operational and functional requirements that the Department needs for automated traffic data systems.
4  Examine potential systems for appropriateness for use by Data Inventory.
5  Select or propose development of an automated retrieval, editing and verification system.
6  Meet with the Technical Panel to discuss recommendations made.
7  Prepare a final report of the literature review, research methodology, findings, conclusions, and recommendations.
8  Make an executive presentation to the SDDOT Research Review Board at conclusion of the project.
