摘要：	Travel time based mobility measures have been increasingly used in highway performance analyses. Among them, Travel Time Index (TTI), Planning Time Index (PTI), percentage of travel under congestion (PTC), and buffer index (BI) have been identified as measures of particular interests in Kentucky. The objectives of this study are: (1) Calculate TTI, PTI, PTC, and BI for freeways within the TRIMARC coverage; and (2) Explore potential correlation between the reliability measures and incident characteristics (e.g., number of incidents, duration, severity, etc.). These analyses were performed for the years 2006-8 for each monitored segment and freeway corridor as well as for the entire freeway system.
