摘要: |
This research project evaluated the effectiveness of dynamic speed display signs (DSDS) in permanent situations where excessive speed can pose a safety problem. One product was required for the project: guidelines on using DSDS at permanent locations. The guidelines have been submitted as an appendix in Research Report 0-4475-1, and can be implemented immediately. The information gathered from this project will also serve as an aid for further research into the effective use of DSDS in other applications. |
