1 VDOT and MAP-21 Performance Management VA SITE Annual Meeting June 27, 2013 Jay Styles Performance and Strategic t Planning Manager, Business Transformation Office

2 Overview Map-21- How is VDOT Preparing? Reviewing National goals/ required measures Reviewing AASHTO recommendations Reviewing current VDOT measures/ initiatives Gap Analysis New initiatives to plug the gaps 2

3 VDOT Performance Management VDOT reports periodic performance to the public, Governor and the Secretary of Transportation in following ways VDOT Dashboard VDOT Business Plan VDOT Quarterly Report Card Virginia Performs 3

4 MAP- 21 National Goals and Performance Measures National Goal Area Safety Infrastructure Condition System Reliability Congestion Reduction/ Environmental Sustainability Freight Movement and Economic Vitality National Performance Measure Area Number of fatalities Number of serious injuries Fatalities per VMT Serious injuries i per VMT Pavement condition on the Interstate System Pavement condition on the non- interstate NHS Bridge condition on the NHS Performance of the Interstate System Performance of the non-interstate NHS Traffic Congestion On-Road mobile source emissions Freight movement on the Interstate System 4

5 MAP- 21 National Goal Area- Safety Federal Requirement AASHTO VDOT Recommendations Number of Fatalities On Dashboard targets for reduction set in Strategic Hwy Safety 5 year moving average Plan (SHSP) Fatality Rate Data available to (Fatalities/ VMT) All public roads calculate Number of Serious Calendar year On Dashboard Injuries Serious Injury Rate (Serious Injuries/ VMT) Data available to calculate 5

6 VDOT s Dashboard Safety Measures Number of Deaths (Fatalities) Targets set by year in Strategic Hwy Safety Plan Number of Injuries Targets set by year in Strategic Hwy Safety Plan 6

7 Map-21 National Goal Area- Infrastructure t Condition Federal Requirement AASHTO VDOT Recommendations Pavement Condition on the Interstate System Good, Fair, Poor Condition based on IRI On Dashboard Pavement Condition on the non-interstate NHS Bridge Condition on the NHS Pavement structural health index (in 3-5 years) Percent of deck area on structurally deficient bridges NHS Bridges in Good, Fair, and Poor condition based on Deck Area Data available but not displayed. Dashboard shows the count of structurally deficient bridges (deck area available internally) 7

8 VDOT s Dashboard Infrastructure Condition Measures Ride Quality- The percent of pavement (lane miles) with average ride quality in the Excellent, Good, or Fair categories (smooth ride). All road segments on the Interstate and Primary road systems in Virginia i i are tested each year and rated in one of the following categories: Excellent, Good, Fair, Poor, or Very Poor. 8

9 VDOT s Dashboard Infrastructure Condition Measures Pavement Condition- Percent of pavement in non-deficient condition. Bridge Condition- Count of bridges not structurally deficient based on the most recent inspection for bridges and culverts in Virginia. Green = Non-Deficient, General Condition Rating (GCR) of 6-9 Yellow = One or more GCR equal to 5 but not Structurally Deficient Red= Structurally t Deficient, i GCR rating of 0-4 9

10 MAP- 21 National Goal Areas- System Reliability/Congestion Reduction/Freight Federal Requirements AASHTO VDOT Recommendations Performance of the Interstate System Performance of the noninterstate NHS Annual Hours of Delay Reliability Index Annual Hours of Truck Congestion at various interstate locations Travel speeds on HOV facilities Traffic Congestion Freight Movement on the Interstate System Delay Truck Reliability Index Travel time on key interstate commuter routes Incident Duration Hours of delay 10

11 VDOT s Dashboard Congestion Measures Congestion at Various Interstate Locations- The percent of traffic (vehicle miles traveled) that moved in good, fair, and poor categories based on the density of traffic. Traffic Speeds on High Occupancy Vehicle (HOV) facilities- The percent of peak period traffic volume, which moved at speeds greater than and less than 45 mph through HOV facilities. Travel time on Key Interstate Commuter Routes- Travel times for selected routes, during peak commuter hours are displayed along with the free flow travel times. Incident duration- How long it takes to clear unplanned events, which affect traffic. Hours of Delay- How many hours of extra travel time are experienced by travelers during the year during peak periods of travel (6 to 9 am and 4 to 7 pm) 11

15 Map- 21 National Goal Areas with Potential Data Needs System Reliability Performance of the Interstate System Performance of the NHS excluding the Interstate System Congestion Reduction/Environmental Sustainability Congestion Reduction Freight Movement and Economic Vitality Freight movement on the Interstate t t System 15

16 Current Status of Traffic Data at VDOT VDOT has a wealth of traffic performance related data: Volumes Vehicle speeds and classifications Travel time Incident and crash data Inventory Corridor and intersection operations Data are distributed among a number of systems Some elements are difficult to access Staff spends significant time integrating data from different sources Still, most questions go unanswered or unanalyzed 16

17 Goals Traffic Data & Performance Management System (TDPMS) will help: Support analysis of VDOT s traffic performance-related data Serve as the archive for the statewide ATMS Support MAP-21 compliance Vision Provide one access point to traffic detector, vehicle probe, incident, roadway network and other data needed to support analysis of traffic performance Create new analysis capabilities by integrating data sets spatially and over time Facilitate performance management through visualization aids, graphics and reports Establish an data archive than can be used with other applications and help meet future needs 17

18 Example Use Cases Report on Congestion Identify and prioritize bottlenecks Report on HOV/HOT Lane Performance Assess Planned Lane Closures Analyze Incident Management Effectiveness Develop Corridor Plans Analyze Project Benefits 18

19 Potential Performance Measures Traffic volumes Average speed Trip time for key corridors Travel Time Index Travel Time Reliability Hours of Delay VMT Bottleneck Locations Throughput Level of Service Incident Frequencies Detector Performance 19

20 Additional Capabilities 20

21 Summary VDOT has the data needed for most metrics that may ultimately be adopted (many are on the Dashboard) Additional tools (TDPMS) would help manage data and reporting in several performance areas System Reliability Reporting on Interstate and NHS Performance Setting Interstate/NHS performance goals Congestion Reduction/Environmental Sustainability Calculate baseline level of traffic congestion Support determination of target performance Help evaluate effectiveness of proposed projects Freight Movement and Economic Vitality Support calculation of actual and target performance 21
