　　Many different Tempered Glass Reflective Road Markers have been sold, manufactured, and used in Taiwan. However, to date, there was no formal test conducted to understand their quality and function. According to these concerns, the IOT has conducted this project. Through multiple testing processes, a reasonable testing design and the standards for each test have been suggested in this report. It is expected that those suggestions can be used as important references for designing official testing principles in the future.

　　There are three major tasks in this project:

1. Investigating the current usage conditions of Tempered Glass Reflective Road Markers in Taiwan.
2. To understand the characteristics of different kinds of Tempered Glass Reflective Road Markers, the study has conducted tests and analysis many times.
3. Making comparisons of markers which had been used on roadways for a certain period of time.

　　Finally, conclusions have been made based on the testing results and the requirements made by current official regulations. It is expected that those results will ensure that these kinds of traffic safety devices provide the best protection for drivers.
