Southwest Washington ITS Traffic Data Collection & Analysis : A Tale of 3 Projects

1. Southwest Washington ITS Traffic Data Collection & Analysis:A Tale of 3 Projects Jill MacKay ITE Traffic Simulation Roundtable October 4, 2012

2. Three Projects • C-TRAN/City of Vancouver TSP Before/After Evaluation • Purpose: Evaluate transit and traffic operations performance impacts of pilot TSP implementation. • RTC TSMO Demonstration Project • Purpose: Measure impacts of improvements on two key arterials • Southwest Region Advanced Traveler Information System Data Evaluation • Purpose: Determine usability and relative accuracy of INRIX™ traffic data for WSDOT traveler information applications.

3. TSP Pilot Project Overview • Mill Plain Blvd between Fort Vancouver Way and 160th Avenue • 22 intersections equipped, 8 included in analysis ITE Traffic Simulation RoundtableOctober 4, 2012

4. TSP Pilot Evaluation Approach • Impacts assessed for both signal ops and transit • 3 Evaluation Phases • Data collected for AM, mid-day and PM peaks • CAD/AVL • APC • Intersection observation • Controller logs ITE Traffic Simulation RoundtableOctober 4, 2012

5. Transportation Systems Management and Operations (TSMO) Demonstration Project Overview • Vancouver RTC TSMO Plan adopted 2011 • Andresen Road and Mill Plain Boulevard • New fiber • Signal upgrades • Intersection improvements • New CCTV and vehicle detection • Desired outcomes • Enhanced signal system performance • Improved response to real-time traffic conditions. • Expanded arterial traveler information • Automated data collection for planning and reporting ITE Traffic Simulation RoundtableOctober 4, 2012

6. TSMO Corridor Evaluation Approach • Before/After evaluation of TSMO improvements • Corridor performance: segment travel times and vehicle speed • Signal timing: percent vehicle arrival during traffic signal green • Ongoing performance verification: vehicle volume, speed, and classification • Travel times • O-D • Volume • Speed • Classification • Percent vehicle arrival while green ITE Traffic Simulation RoundtableOctober 4, 2012

7. WSDOT ATIS Data Evaluation Overview • Exploring viability of third-party data for powering WSDOT traveler information systems WSDOT INRIX Data Purchases • Statewide • One year of historical data • Access to INRIX Analytics • Accessible by all public agencies in WA • Southwest Region + Routes into Portland • One year of real-time data ITE Traffic Simulation RoundtableOctober 4, 2012

8. WSDOT ATIS Evaluation Approach • Data Collection • INRIX Speed and Travel Time • WSDOT Loop Data (PORTAL) • Probe vehicles • Data Processing • Mapping corridor to TMC segments • Data Analysis • Calculate average travel time and speed for corridor (1 min intervals) • Calculate MOEs by corridor and speed bin • 0-30 bin is key ITE Traffic Simulation RoundtableOctober 4, 2012

9. Next Steps Project Status • TSP Pilot: “Before” data collected, RFP for installation of signal equipt. to be awarded Nov. 13 • TSMO Corridor Demonstration: Bluetooth vendor & installation contractor in procurement • WSDOT ATIS: Preparing for probe vehicle data collection Continue to Explore Potential Cross-Project Coordination • Use of TSMO data to perform evaluation of INRIX arterial data • Installation of Bluetooth for additional freeway evaluations ITE Traffic Simulation RoundtableOctober 4, 2012
