  • Abstract:
    This report presents the procedures involved in the research, design, construction, and testing of an Automated Road Closure Gate. The current road closure gates used in South Dakota are often unsafe and difficult to operate. This report will assist the South Dakota Department of Transportation in determining whether a remotely controlled drive unit in combination with the new gate design is cost effective. Completion of the project was to involve executing 14 tasks to fulfill three objectives. The objectives could not be fully met due to installation delay of the gate that was to be used on this project. The objectives were to design, build a functional prototype, and install a remotely activated road closure gate. The first was fully met, the second partially met, and the third was not met. Research was first performed pertaining to remotely activated road closure systems. The researchers then met with the Project's Technical Panel and South Dakota School of Mines and Technology (SDSM&T) Professors to discuss any issues or concerns they had with the project. A conceptual design was developed and approved by the Technical Panel and SDSM&T Professors. A preliminary design was developed and approved. The preliminary design was modified to accommodate a scaled model of the gate. The scaled model of the Automated Road Closure Gate was built and tested in the laboratory. An unsuccessful attempt was made to calculate the crashworthiness of the new system. The findings and recommendations were presented to the Research Review Board in a presentation on April 4, 2000. The findings included the following: Low quality parts used for the prototype and scale model proved to be unreliable. Complex programmable Logic Devices may not have been the best processing units to use in the design. A linear actuator made by Jordan Controls was determined to be the best drive unit to raise and lower the gate. The recommendation for the road closure gate is to purchase a gate similar to the proposed design. Hy-Security is the recommended vendor for this purchase. Recommendations for future projects with student researchers are provided in the Implementation Recommendations section of this report. References, 5 appendices, 31p.
