  • Most of the US interstate highways have passed or will exceed their design life in the next 20 years and need preservations.
  • DOTs are always on the look for the optimal solutions that make their investments effective and efficient.
  • Predictive analytics enable DOTs to make effective decisions, prioritize maintenance tasks and provide efficient life-cycle planning for Transportation Asset Management (TAM).
  • Among different available prediction models, the techniques that provide information on the occurrence probability of defects throughout roadways are believed to better present each defect’s risk of happening.
