Title: Work Zone Safety Device Evaluation
Project Researcher: Patrick McCoy,
Project Manager: Dave Huft
Research Period: -
Status:
Cost: $0.00

Problem Statement:The safety of workers and the traveling public in highway workzones is an increasingly important concern. Escalating traffic volumes and additional miles of aging highways will require increasing numbers of highway workzones.

In South Dakota in the last nine years 1587 accidents occurred in workzones causing 812 injuries and 18 fatalities. Two major causes for unsafe workzones are excessive vehicle speed and the traveling public failing to recognize and/or comprehend the message being conveyed by the traffic control device.

Findings:

Research Objectives:
1  To identify and evaluate traffic control devices which decrease the speed of the traveling public in workzone areas.
2  To identify and evaluate traffic control devices which improve recognition and/or comprehension of traffic control devices in workzone areas.

Research Tasks:
1  Conduct a detailed literature search and summarize relevant research on this subject.
2  Submit a prioritized list to the technical panel of all traffic control devices which have the potential to decrease the speed of the traveling public in urban and rural workzone areas. The list should at least include advantages and disadvantages o
3  Submit a prioritized list to the technical panel of all traffic control devices which have the potential to improve the recognition and/or comprehension of traffic control devices in urban and rural workzone areas. The list should at least include a
4  After the 6 traffic control devices have been selected by SDDOT for field testing, the researcher shall submit a detailed plan on how each selected device will be evaluated for its effectiveness to decrease the speed of the traveling public or improv
5  Evaluate the effectiveness in actual field condition of the 6 selected traffic control devices.
6  Submit a final report summarizing relevant literature, research methodology, data, implementation, recommendations and possible further research.
