• Abstract:
  Curve warning signs are intended to improve curve safety by alerting the driver to a change in ; geometry that may not be apparent or expected. However, several research projects conducted in the last 20 ; years have consistently shown that drivers are not responding to curve warning signs or complying with ; advisory speed plaques. ; A new engineering study method was developed to improve consistency in curve signing and driver ; compliance with advisory speeds. This report documents two activities that were conducted to promote ; implementation of the new method. One activity is the development of a software program to measure curve ; geometry while driving through the curve. The geometric data are then used to determine an appropriate ; curve advisory speed and to select effective, curve-related traffic control devices. ; The second activity for this project was a series of workshops that described use of the new method. ; The workshop provided a mixture of classroom discussion and hands-on training activities for the ; participants. The workshop participants generally indicated that they believed the new method would benefit ; their districts and looked forward to implementing it. Recommendations for future research in this area were ; identified.
