Road Construction Safety Project SDMay04-01
Introduction Project/Design Requirements
•Abstract •Design Objectives
Each year, highway fatalities reach increasing levels. The majority of these accidents, and even • Cost-effective
more injuries, were the result of rear-end collisions because of drivers’ inability or unwillingness to
• Low maintenance
recognize the dangers of upcoming work zones. The focus of this project is to increase the
cognitive awareness of drivers near construction zones. Additionally, it must establish methods to • Easy to setup/use
adequately educate and warn Iowa’s drivers of the dangers associated with construction on two-
• Durable
lane highways. The main objective is to save human lives by decreasing the frequency of
accidents. •Functional Requirements
•Acknowledgements • Activate drivers’ cognitive decision process
Thank you to the Iowa Department of Transportation, Veronica Dark, and the CCEE and ECpE • Convey desired message in a limited amount of time and space
departments of Iowa State University for their assistance and insight on this project.
• Device allows for relocation and be updateable as necessary
•Problem Statement • An educational solution conveys desired message
The problem, for which this project will determine a solution, is that drivers are not making the •Design Constraints
cognitive choice to recognize the danger in, and around, construction zones. Drivers tend to ignore
warning signs because they become accustomed to seeing them, or do not see work in progress and • Must meet federal guidelines
believe danger no longer exists. • Able to withstand adverse weather conditions and relocation
Looking at many different approaches, this project will find a solution which stays within the • Re-useable power supply
proposed constraints and lives up to the client’s requirements. Improved current, as well as new
technology will be used to help solve this problem. • Measurable Milestones
