8 8 U.S. Department of Transportation Connected Vehicle Environment

9 9 U.S. Department of Transportation Organizing Principles  Privacy by design in all parts of the implementation, □ Users should trust that their private information will not be revealed or used without their knowledge and permission.  Security by design Information on how the Security Certificate Management System impacts privacy and security of data (SCMS)  Nation-wide interoperability of safety-related communications, □ Information that improves the safety of transportation services should be done the same way nation-wide.  Nation-wide interoperability of non-safety related communications, □ Information that provides improved mobility or environmental impacts should be presented in a consistent manner to all users, regardless of origin.  Equitable access for individual users to basic transportation data, □ Everyone should have access to data available for safety and mobility improvement using the equipment of their choice.

10 10 U.S. Department of Transportation Safety Pilot Model Deployment Program  73 miles of instrumented roadway with 27 roadside units in Ann Arbor, MI  Over 2,800 vehicles equipped with a variety of device types  Various V2V and V2I applications  Testing of prototype security mechanisms and device certification processes  1 year of data collection to support 2013 NHTSA decision  Transitioned to an operational environment

13 13 U.S. Department of Transportation ICF/Wyoming Pilot Deployment Overview Objective:  Reduce the number and severity of adverse weather- related incidents (including secondary incidents) in the I-80 Corridor in order to improve safety and reduce incident-related delays. □ Focused on the needs of the commercial vehicle operator in the State of Wyoming Approach:  Equip fleet vehicles (combination of snow plows, maintenance fleet vehicles, emergency vehicles, and private trucks) that frequently travel the I-80 corridor to transmit basic safety messages (BSMs), collect vehicle and road condition data and provide it remotely to the WYDOT TMCs  Deploy DSRC roadside equipment (RSE) to supplement existing assets and initiatives  Road weather data shared with freight carriers who will transmit to their trucks using exiting in-vehicle systems Source: Wyoming DOT Deployment Team:  Prime Consultant: ICF International; Partner State: Wyoming DOT  Sub Consultants: Trihydro Corporation, National Center for Atmospheric Research, University of Wyoming, Catt Laboratory and McFarland Management

14 14 U.S. Department of Transportation ICF/Wyoming Pilot Deployment Vision

15 15 U.S. Department of Transportation Research Data Exchange (RDE)  The RDE is a Web-based resource that collects, manages, and provides access to multi-source and multi-modal transportation data  Quality-checked, well-documented, and freely available to the public  Currently has ITS and connected vehicle data from 17 locations  More data environments will be added, including data from Dynamic Mobility Application (DMA) prototypes.  The Saxton Traffic Operations Laboratory may hold data that cannot be released to the public Connected vehicle, mobile device, and infrastructure sensor data captured during the Smart City Demonstration are expected to be broadly shared with the community to inform prospective deployers of Smart City applications https://www.its-rde.net/

16 16 U.S. Department of Transportation Remember: DSRC – a Key Part of Communications  Large-scale pilots are underway that will exercise the complete system architecture with the full capability of DSRC  We have arrived at a consensus of interpretation of standards for the next generation of installations  Production programs are underway DSRC is ready to be part of the next Generation of Wireless Media

17 17 U.S. Department of Transportation What are the Next Steps?  Identify and engage stakeholders and technical experts!  Follow the CV Pilot Deployers (http://www.its.dot.gov/pilots/index.htm)http://www.its.dot.gov/pilots/index.htm □ ICF/Wyoming □ New York City □ Tampa (THEA)  Seek out Training Opportunities (https://www.pcb.its.dot.gov/)https://www.pcb.its.dot.gov/ □ CV 101 Connected Vehicle Basics □ CV 102 Applications and Planning for Implementation □ CV 201 Deployment Planning for Implementing a Connected Vehicle Environment

23 23 U.S. Department of Transportation Automated Lane Change/Merge  Research Question: Can the use of automated control, V2V, I2V, and/or vehicle sensors to execute traffic movements such as lane change and merge maneuvers assist in fully realizing the identified mobility and safety benefits of other connected automated applications (e.g., CACC)?  Work to Date: A connected, automated lane change maneuver was successfully demonstrated on a close course with three vehicles. □ The maneuver took approximately 10 s to complete □ The vehicles were able to maintain desired spacing with minimal error (within 2 m), speed oscillation, or passenger discomfort.
