ODOT by the Numbers 49,397 Lane-miles 10,367 Traffic sections 227 Pavement projects in 2013 21,465 Projects in history database ODOT's Pavement Management System
ODOT by the Numbers 12,913 PCR sections in 2013 29 Years of PCR data 251,339 Historical PCR sections ODOT's Pavement Management System
ODOT Data Strengths and Weaknesses • Weaknesses • Lack of analysis tools • Reduced staff • Staff turnover • Strengths • Data rich • Consistent PCR • Detailed distress data ODOT's Pavement Management System
Pavement Management System dTIMS Deighton Total Infrastructure Management System ODOT's Pavement Management System
Pavement Condition Rating • PCR = Pavement Condition Rating • Zero to 100 scale • 100 is best • Visual inspection of distresses • Deduct values determined based on severity and extent of distresses ODOT's Pavement Management System
