A new program dedicated to be the first fiber optic pavement monitoring system in Taiwan is introduced. The overview of the project and the state of sensor design, calibration and test are presented, emphasizing a three phases of sophisticated research study that include novel fiber grating sensor developments, laboratory and field tests, and long-term pavement performance monitoring and analysis. Preliminary results indicate that accuracies of ± 30 με and ±1.5 °C for strain and temperature can be achieved, respectively. Future works is also discussed.
