Transcription

1 Using Traffic Signal System Performance Measures to Evaluate, Prioritize, and Sell ITS Texas 2016 Annual Meeting Brian A. Moen, P.E. City of Frisco Tel: (972) Curtis Jarecki, P.E. City of Frisco Tel: (972)

2 Overview Traffic Professionals Need to Publicize Accomplishments Automated Performance Measures Help Traffic Signal System Investments Evaluate Prioritize Sell, Build Support

3 Limited Resources Annual Budgets / Bond Funds Traffic will Get Worse (Despite Our Best Efforts) A Playbook of Ways to Gain Support

4 Tell the Story Be Proactive, Introduce the Issue to the Public Be the First to Tell the Story Redefining an Issue Is Difficult

5 Promote, Market

6 Promote, Market

7 Performance Measures What is a Performance Measure? Regular measurement of outcomes and results, which generates reliable data on the effectiveness and efficiency of programs (US Department of State, Bureau of Educational and Cultural Affairs)

8 Measuring Ways to Measure Performance Automated Performance Measures Asset Management System Work Order Management System Traffic Management System (ATMS) Automatically Collected Travel Times

9 An Example Adaptive Control System Evaluation

10 Adaptive Control Common Questions Does Adaptive Control Work? For Which Traffic Conditions does Adaptive Control Work Better? Evaluation Use Automated Performance Measures to Measure the How an Adaptive Control System Performs

11 Project Scope Evaluate Adaptive Control Determine the Best Practices for Collecting Automated Performance Measures Evaluate Lane versus Approach Detection Evaluate Crowd Sourcing versus Discrete (BlueTooth/WiFi) Travel Time Data Collection

12 Tools for Evaluation Automated Performance Measures Purdue Coordination Diagram Reason for Termination Volume to Capacity Charts Travel Time Travel Time Reliability

13 The Test Corridor

14 The Main Event The Challenge 3 Options Our Best Semi-Actuated Timing Fully Adaptive Semi-Adaptive, Critical Intersection Control

15 Baseline Baseline Recently Calibrated Signal Timing Designs Our Best

16 Fully Adaptive Fully Adaptive Let the Adaptive Control System Adjust Cycle Length, Adjust Offsets, and Adjust Splits

17 Semi-Adaptive Critical Intersection Control Adjust Splits Fixed Cycle Length and Fixed Offset

18 Evaluation How Does Each Option Perform Under Different Levels of Traffic Congestion? for Recurring Traffic Conditions? for Variable, Unpredictable Traffic Conditions?

19 Evaluation Measure and Compare using Automated Traffic Signal Performance Measures Travel Time Travel Time Reliability Approach Delay (Green Time Equity) Percent Arrival on Green (Stops) At Traffic Signals in the Test Corridor At Traffic Signals Adjacent to the Test Corridor

20 Results Know Where and When to Use Adaptive Control Develop Best Practices for Collecting Traffic Data Reveal Hidden Issues Maintenance Problems Equipment Issues

21 Prioritize Data to Objectively Measure Traffic Congestion Objective Feedback to Pick the Right Solution to a Problem Choose a Solution ITS (Traffic Signal Equipment/Software) Intersection/Corridor Capacity Improvement

22 Sell, Build Support Become a Believer, Sell Yourself First Beyond a feeling. Know it is Better and When it is Better. Enthusiasm. Then Sell Others, Build Support Measured Improvement Develop Charts and Tables to Support Selection

23 Sell, Build Support Who Are We Trying to Sell Ourselves Director City Management Mayor/City Council Residents

24 Playbook Ideas Use Automated Performance Measures Make Proactive Traffic Signal Adjustments Balance Green Times (Splits) Develop a Corridor Performance Index

25 Playbook Ideas Use Automated Performance Measures Report Benefit of Roadway Improvements Roundabout Replaces Traffic Signal Corridor/Intersection Improvements Changes to Signal Operation (FYA installations, change left turn mode of operation)

26 Playbook Ideas Use Automated Performance Measures Origin Destination for Special Events, Infrastructure Planning, Economic Development Travel Time Reliability Trip Spread

27 Results Quality of Life Reliable Traffic Signal System Performance Economic Development Attracts People and Businesses Comparisons to Other Systems (think crime statistics and school rankings)

28 Empowered to Tell the Traffic Story

29 Support, Investment Resources and Staff Needed Expansion of Current Projects Funding for Future Projects

30 Questions Traffic Technology Services (TTS) and City of Frisco Connected Vehicle Demonstration Brian A. Moen, P.E. City of Frisco Tel: (972) Curtis Jarecki, P.E. City of Frisco Tel: (972)
