1 Traffic Data Programs at Virginia DOT: 10 plus Years of Innovation Presented by Digital Traffic Systems Inc. Mr. Peter Keen NATMEC 2012 Dallas, Texas 6/5/2012

2 Business Partner Perspective Managing a state traffic data program in challenging times Budget Constraints provide an opportunity for innovation Pressure to Outsource implies a value judgment Outsourcing opens up new possibilities Embrace them! o DOT staff as the data experts can focus on: Meeting current customer data needs Expanding your products to serve emerging needs efficiently Program Management Align Goals thru the Procurement Process i.e. create a Win/Win Doing More Will Get You More Recognition, $$$, & Relevance Use Private Sector Contractors as Business Partners o Innovation rewards both parties => more sites/data for a given budget spend o Selecting the right partner can bring other experiences to the table Within the Department and with external agencies Provide staffing flexibility, skill sets and capacity

3 DTS Expertise Our roots are Traffic Data Collection Sensor Systems Installation, Integration, & Maintenance ITS Installation, Maintenance, & Service CCTV Design, Installation, Maintenance, & Service Machine Vision Technology Video Transmission & Compression Wide-Area Networks Structured Cabling Solar / Alternate Power Implementation Adaptive Traffic Signalization & Signage 3

4 Virginia CCS Data Program 4

5 ITS On-Call/Maintenance On-Call ITS Maintenance 24/7/365 Emergency corrective response and scheduled maintenance provided 24/7 CCTV (Solar and AC powered) Dynamic Message Signs (DMS) Remote Weather Information Systems Weather and Fog Detection and Warning Systems In-road Restricted Visibility Lighting T1, DSL, Fiber, and Wireless Communications Highway Advisory Radio (HAR) License Plate Readers (ANPR) Traffic monitoring devices, and other traffic management field equipment. Task Work Order Capability to expand use of ITS assets 5

6 Statewide Real-Time Video & Data Services Contract Requirements o Statewide rapid deployment response o Multi-Sensor platform Accepted Mobile System o Towable CCTV platforms o Self Contained Weather and Traffic Data Sensors o Wireless communication o Solar powered Users o Traffic Operations Centers o Emergency Operations Centers o Planning/Engineering 6

7 VDOT Traffic Monitoring Mission Traffic Link Annual Average Daily Traffic (AADT) Estimates System Vehicle Miles of Travel (VMT) Estimates Meet the Department s Other Traffic Data Needs Key Products: 1 Statewide Interstate & Primary Route AADT Report 335 Individual Jurisdiction AADT Reports 20 VMT Reports

8 Meet Department Traffic Data Needs Annual Traffic Push to Roadway Network System for Integration of Data to Other System Needs HPMS Annual FHWA Submittal Pavement Management System Transportation Mobility Planning Division Materials Division & MEPDG Requirements Monthly FHWA Submittals for Travel Trends Performance Measures (Dashboard and Other) Real-time Traffic Data (i.e. data provided to the regional TOCs) Speed and Travel Time Data (future)

9 How VDOT s Traffic Monitoring Program Operates One Count Program Fourteen Staff Assigned Program Manager Field Engineer TMS Data Engineer WIM Manager Four Contract Administrators Three Data Analysts Senior Electronics Technician Two Field Inspection/Operations Staff Purchase Quality Data through 13 Contracts

10 Multiple Contracts to Administer Performance-based Contracts Payment made based on Quantity & Quality of Data Traffic Monitoring Program Permanent Sites CCS In-Pavement Sensors 5 regional based contracts NCCS with integrated polling services statewide VDOT Owns Site Infrastructure and In-road sensors Business Partner Owns and Operates the Electronics ATR, radar-based non-intrusive sensor, surge protection, communications equipment, etc. Traffic Monitoring Program - Portable Counts Seven Region / District Based Contracts Business Partner Owns and Operates Equipment

11 Essential Contract Elements Business Model - Purchase Quality Data VDOT Performs Data Quality Checks Contractor Paid for Quantity and Quality Data One Contractor Philosophy Responsible for Installation Quality Responsible for Performance of Electronics No Finger Pointing Responsible for delivering quality traffic data Sensor Installation Inspection VDOT has no on-site inspection staff Contractor Provides Self Quality Assurance Inspection Documentation Includes Continuous Video, Photo and Paper Records All Documentation Reviewed by VDOT Staff Videos Saved for Historical Research & Review Process Changes? Lessons Learned

12 Virginia s Traffic Data Program In Road Sensors 239 Non-Intrusive 6,349 Classification and Speed 10,345 Axles Only 92,200 WIM Continuous Count Stations 48 Hour Counts 24 Hour Local Counts 12

13 Continuous Count Stations (CCS) In-road Sensors 13

14 All Continuous Count Stations 14

15 Program Success Stories Traffic Operations Centers use Planning Data for Operations Increases the size of the overall sensor network Better Value i.e. Quality Free Data Real-Time Stop Watch Data from In-Road Sensors Real-Time Data Non-Intrusive Innovative Sensor Installation Processes 4 deep loops Double stack deeper piezos Sites last longer, even as pavement deteriorates Maintaining twice as many sites for same annual maintenance budget 21 Bin Classification Table Assess Piezo Sensor Condition Extends Life of Sensor

16 Constant Process Evaluation and Improvement Developed Detailed Installation Procedures o Constantly evolving => Goal is Continuous Improvement Material Selection o High quality durable materials Equipment Selection o Leverage innovative features o Plan for the unknown /challenging conditions e.g. oversized panels Meticulous Attention to Detail o Saw Cutting Templates o 1 conduit per sensor

17 ITS and Planning Data Comparison Philosophy ITS Data is One of Many Tools Incident Management is Focus Planning Data is King Primary Use Immediate Use for Operations; Little Historical Value Long-Term Use; Significant Historical Value - Trends Sensor Location Often must be Point Specific Many sensors - Urban-centric Statewide, Sparse Sweet" Spot

18 Data Quality Control by the Data Snobs Initial Site Set-Up & Calibration to build quality in Data Used Real-Time and Downloaded Daily Reviewed by Automated Processes (Contractor and VDOT) Over 50 Performance Checks Daily System Generated Data Quality Rating Suggested Manual Operations Review System Messages & Suggested Quality Rating Research Performance or Data Issues Request Maintenance Assign Quality Rating Advises Customer How Data Should Be Used Used for Computing Payment for Purchased Data Extensive Service Call Procedures and documentation to address issues

19 Degraded Piezo Performance - Graph 400 Vehicle Classification - Data Quality US-1 SB Lane 1-10/15/ Volume Class

20 Virginia Today ~600 Total Continuous Count Stations and Growing

21 Closing Thoughts Assess DOT's Needs / Goals formalize in a Data Plan Be willing to take risks o Look for quick successes and build on them o Don t let perfection be the enemy of good o Learn from the failures as well as others success They can be the driving force for innovation Performance Based Contracting o Emphasis on qualifications and deliverables o Only Purchase Quality Data Market Your Data As A Strategic Asset!
