Pavement & Bridge PM2 System Performance PM3 Karen Owen September 19, 2018

National Highway System

Pavement & Bridge Condition Performance Measure Condition Reporting Period Percentage of Pavements Interstate Good & Poor Biennially, with 4 year Non-Interstate NHS Good & Poor performance periods Percentage of Bridge Deck Area National Highway System (NHS) Good & Poor

Data Limitations ▪ Pavement & bridge data analysis • Collected data versus data required for federal measures • Incomplete data • Missing data ▪ Continue coordination with TxDOT

Regional Conditions & Targets ▪ Historical percentages of Pavement & Bridge averages: • Good & Fair = 50/50 split • Poor = Less than1%, except 11% for Non-Interstate NHS pavement ▪ Set Targets for 2020 & 2022 based on a historical trends

System Performance (PM 3) Performance Measures Karen Owen September 19, 2018

System Performance Measures (PM 3) ▪ Reliability • Personal Miles Traveled • Freight Travel Times ▪ Congestion • Peak Hour Excessive Delay • Non-SOV Trips

Reliability Performance Measures Measure Applicability Reporting Period Interstate Percent of Person-Miles traveled Biennially, with 4 year Non-Interstate that are Reliable performance periods National Highway System (NHS)

What is Reliability? ▪ Level of Travel Time Reliability (LOTTR) – Ratio of the 80 th percentile (bad traffic) to the 50 th percentile (normal) travel time ▪ “Unreliable” roadway - the driver will allow 90 minutes for what is normally a 60 minute trip (60 minutes x 50%)

Reliability Target Setting Draft Regional Targets % of Person-Miles traveled 2017 2020 2022 that are Reliable Baseline Target Target Interstate 63% 56% 50% Non-Interstate National Highway System 73% 63% 52%

H-GAC Programs ▪ Reliability strategies • Tow & Go Program • Intersection improvements • Capacity projects • Grade separations • TransStar • Call for Projects • Increase transit use

Freight Reliability Measure Applicability Reporting Period Biennially, with 4 Year Truck Travel Time Reliability Index Interstate Performance Periods Ratio of the 95 th percentile to the 50 th percentile (normal) travel times

Freight Reliability Targets Draft Regional Targets Performance Measure 2017 2020 2022 Baseline Target Target Truck Travel Time Reliability (TTTR) Index 2.1 2.5 2.5

Congestion - PHED Peak Hour Excessive Delay (PHED) ▪ The average amount of extra travel time experienced by the traveling public annually on the National Highway System.
