1 Approach to Measure of Effectiveness Shahram Malek, PhD, PE Regional Traffic Operations Project Manager

2 RTOP RTOP Goals Regional Traffic Operations Program Address Traffic Signal Maintenance and Repair Regionally significant traffic signal corridors in Regional Atlanta Focus 2010: 430 signals 2016: Over 1,100 signals

3 RTOP Teams RTOP Supporting Goals GDOT Address Traffic Signal Maintenance and Repair RTOP 1 (600+ signals) Chester Thomas, PE PTOE RTOP GDOT Manager ChThomas@dot.ga.gov RTOP 2 (500+ signals)

4 Regionally Significant Corridors I-285 ( The Perimeter ) shown with a black line

5 RTOP Goals Preventative Maintenance STC 1 Address Traffic Signal Maintenance STC 2 and Repair ATC STC 3 Contractor STC 4 STC 5 LED Display Upgrades ITS Projects Loop Contractor GDOT 1 Count Data Signal Maintenance Contractor Actively Manage Loop Contractor Traffic Flow 2 STC 6 Timing Contracts Traffic Engineer Loop Contracts Local Agencies Signal Shop CID

6 RTOP Mission: To increase travel reliability by minimizing congestion and reducing delays along regional commuter corridors through improved signal operations.

7 Firsts Shared Communication Network RNET Program Based Technology Evaluation Cloud Based Traffic Signal System Citrix Successful TR operation in GA Across Jurisdiction Boundaries Video Sharing Architecture Ethernet over Copper Wireless Ethernet IP-based CCTV Retroreflective Backplates Deployments of Flashing Yellow Arrow Deployment of regional travel time detection system

8 RTOP RTOP Primary Goals Tasks Address Active corridor Traffic Signal management Maintenance (incidents) and Repair Regional Traffic signal Focus timings Traffic signal maintenance Traffic signal infrastructure

9 RTOP Goals Staff Address Traffic Signal Maintenance and Repair GDOT management Corridor managers Traffic signal technicians TMC operators Traffic signal contractors

10 RTOP Signals Traffic Signal Operation Changes RTOP Goals # of RTOP Signals Running Free Uncoordinated No Comm CCTV Address Traffic Signal Maintenance and Repair Time-of-Day Plans Cell Modem Traffic Response Wireless Fiber Optic Adaptive RTOP Signals Communication (Current) (Current) (Current) Year Year Year RTOP CCTV's CCTV

11 Performance Measure: Now & Future Performance influences RTOP Goals Address Traffic Signal Maintenance and Repair Initial performance Regional Focus measures (2010) Current performance measures Future performance measures

12 Performance RTOP Goals Influences Address Economic Traffic changes Signal Maintenance and Repair Road construction impacts Road/intersection improvements Shifting traffic patterns Price of fuel

13 Initial Performance Measures (2010) RTOP Goals Detection performance Address Traffic Signal Maintenance and Repair Travel time runs Traffic volumes Actively Time & fuel Manage benefit Traffic Flow Malfunction identification source

14 Vehicle & Pedestrian Detection Performance 100% 95% Program Goal 95% 90% 85% 80% 75% RTOP 1 Results

15 Travel Time Runs RTOP Goals Address Traffic Signal Maintenance and Repair Stops Delay

16 Traffic RTOP Volumes Goals Address Traffic Signal Maintenance 16.9% 17.5% 18.2% Vehicle Miles Traveled Increase and Repair 14.6% 11.8% Percent Change Priority to 0.0% Mainline 0 4.1% 4.3% -2.4% 5.3% 7.8% 1.0% Cross-Jurisdictional -4.0% 4.7% 3.6% 2.5% 1.6% 2.4% Travel Time Increase FALL 2010 SPRING 2011 FALL 2011 SPRING 2012 FALL 2012 SPRING 2013 FALL 2013 SPRING 2014 FALL 2014 SPRING 2015 RTOP 1 Results

17 Time RTOP & Fuel Goals Benefit Address 16 Traffic Signal Maintenance $14.71 and Repair Time & Fuel Benefit (millions) $ $9.04 $8.93 Priority to $5.24 Mainline $ $16.96 $18.15 $16.98 RTOP 1 Results

18 Malfunction RTOP Identification Goals Source Address Traffic Signal Maintenance and Repair RTOP1 Results

19 RTOP Goals Current Performance Measures Address Traffic Signal Maintenance and Repair Travel time system Traffic Priority signal to Mainline asset tracking Actively Automated Manage monthly Traffic report Flow spreadsheet

20 Travel Time System

21 Major Incident Example RTOP Goals Address Traffic Signal Maintenance and N Druid Repair Hills Road Direction: Southbound Date: 02/10/2016 Location: Incident Clear Time: Approx. 30 mins.

22 Time periods of interest Travel Times RTOP Goals Morning peak period: 4 hours (6 10 AM) Address Mid-day: Traffic Signal 5 hours Maintenance (10 AM 3 PM) and Repair Afternoon peak period: 4 hours (3 7 PM) Reliability Buffer Time Index (BTI) Travel Time Index (TTI) Free Flow Conditions = 1 No variation = 0

23 Traffic Signal RTOP Asset Goals Tracking Asset Management Malfunctions Incidents Operational Preventative Maintenance Reporting Address Traffic Signal Maintenance and Repair Accident Management

24 Automated Monthly Report

25 Automated Monthly Report

26 Automated Monthly Report

27 Future Performance Measures RTOP Goals Address Traffic Signal Maintenance and Repair High definition data Real-time dashboard Improved benefit calculations

28 Benefit Calculation RTOP Goals Opportunities 24/7/365 travel time and fuel Address Traffic Signal Maintenance and Repair Freeway incident-related benefits Safety Return on investment on Actively equipment Manage up-time Traffic Flow Economic growth

29 Benefits Technical RTOP Goals Challenges Address Defining Traffic the no-build Signal Maintenance baseline metrics and Repair Regional Tracking safety Focus benefits Calculating regional impact Actively Manage Traffic Flow
