The Virginia Connected and Automated Corridors Zac Doerzaph Virginia Tech Transportation Institute
Notable CV Efforts Underway at VTTI • *Virginia Connected and Automated Corridors (VDOT/VT) – focus of this presentation • Connected Vehicles and Infrastructure University Transportation Center (OST/VDOT/VT/UVA/Morgan State) – over 23 CV projects funded • V2V systems engineering and vehicle integration research (CAMP/NHTSA) • Human Factors for Connected Vehicles Program (NHTSA) • Several other CAMP/USDOT collaborative efforts covering both V2V and V2I
Where are we headed? • Bring Virginia Connected Corridors (VCC) to maturity • Complete the infrastructure build out • Build a developer friendly CV environment • Recruit drivers with frequent corridor interaction • Begin providing solutions to local challenges while taking a leadership role in national CV Deployment activity • CV Pilot Regional Deployment • Up to $20M federal funding • Regional deployment that addresses real world transportation challenges
CV Pilot Regional Deployment • VDOT submitted proposal with partners VTTI and Iteris at the end of March ‘15 • Several awards expected nationally – a few large scale such as VA’s proposal • Each pilot deployment site is expected to be developed in three distinct phases • Phase 1: Concept Development (12 months) • Phase 2: Design/Build Test (up to 20 months) • Phase 3: Operate and Maintain (18 months) • Only recipients of Phase 1 funding will be eligible for Phase 2 and 3 funding
Backend Software Development Activities • Mature the Virginia Connected Corridors (VCC) Environment • Build a scalable data management system from the ground up • Integrate infrastructure components • Provide key system services • Archive message traffic • Create a developer-friendly CV environment that facilitates rapid application deployment • Expose message traffic and communications mechanisms to application developers – security and privacy retained! • Create open API/SDK with reference applications for 3rd party developers • Build our own initial applications using these tools to validate the process • Develop VCC Situation Awareness • Create a monitoring application that facilitates situation awareness of CV asset activity on the corridor (e.g. RSE status, backend connectivity, OBE status, etc.) • Evolve tools to account for deployment scale • Develop analytics and performance monitoring tools
Near-term Development on VCC • Complete basic functionality build-out • Finish cellular communications handling capability • Expand the asset management capability • Asset status reporting, software versions, etc. • Implement application store deployment strategy • Equip an additional 50 vehicles on corridor • Initially with OBEs to exercise message handling • More capability as application development and deployment require it • Expand RSE installations • Resolve connectivity issues with existing installations • Install additional RSE • Create detailed specifications for initial end-user applications
Software Development Challenges • Immature Standards • OTA standards are the most exercised but still fluid • Other message standards are not yet complete or consistent • Expecting multiple iterations moving forward • Security • Unclear who operates SMCS and other services • Federal activities are working to standardize security • What to do in the interim? • Speculative Development • Requirements either don’t exist or are evolving • Can’t wait for full specification before starting
A toolset for Connected Automation Research and Development Created through a partnership between
The Challenge • Vehicle automation development is progressing at a rapid pace • Pre-deployment testing requires complex vehicle interaction scenarios and real roadway environments • The availability of real-world test environments is extremely limited due to reliability and safety concerns Challenge = Opportunity
The Virginia Automated Corridors (VAC) • Build an automation-friendly environment • Support independent research and development • Provide standardized test and certification protocols • Make good on Governor’s Proclamation and facilitate automated systems-related business in Northern Virginia photo by Steven Mackay
VAC Test Bed Characteristics • Smart Road – Controlled test environment with bridge, markings, intersections, weather-making capabilities, variable lighting, roadside equipment • Virginia International Raceway – Reconfigurable track, operations at higher speeds, elevation changes, complex curves • HOT lanes in NoVa– Open operational environment, limited-access express lanes • Real roads in NoVa(I-66, I-495, I-95, rural) – Includes the many details and challenges of public roadway systems • Potential for expansion to any public roadways to satisfy unique test requirements
Interstates and Arterial – 70 miles • Rural Arterial – 22 miles • Interstate – 48 miles
Routes 50/29 Arterials – 8 miles Part of current VCC test bed
Roads facilitate testing • Open and controlled roadway networks to test systems at a variety of maturity levels • Variety of real challenges on Nationally representative routes • Lane Markings • Prioritize painting along route to provide vision systems with needed contrast • Different levels of degraded pavement markings in specified areas
Mapping/Localization Capabilities • High-definition maps via Nokia HERE™ • Ubiquitous 1 cm accurate localization via: • Multi-channel, high-precision global navigation satellite system (GNSS) with real-time kinematic (RTK) corrections • Inertial Navigation System (INS) providing dead-reckoning • Independent road surface vision system providing précising lane position information • Up to 100 Hz update rate
Data Acquisition Services • DAS precisely records time-synchronized data to the nearest millisecond • Base packages typically include: • Connectivity to vehicle network(s), such as CAN, Ethernet, serial, etc. • A minimum of two cameras; up to six cameras when needed • Motion sensors (accelerometers, gyroscopes, and magnetometers) • Radar, LIDAR, vision and/or other ranging/tracking sensor(s) • Differential Global Positioning via multi-channel receiver and RTK corrections • Additional sensors added as needed for specific efforts
Remote Monitoring and Data Streaming • DAS connected via cellular connectivity to backend network at all times • Allows for remote monitoring of system health; enables for remote system shutdown • Allows for real-time viewing of telemetry data, including video • Supports coordination of multi-vehicle scenarios • Supports coordination of V2I applications
Certification for Safe Human Research Involvement Includes assistance with: • IRB application and process management • Smart Road safety evaluation prior to running on public roadways (moving towards certification process) • License plate and insurance, which is provided through Virginia
