The Future of Transportation and the Impact of Connected and Automated Vehicles Cathy McGhee, P.E. August 29, 2016
VDOT has been active in the Connected Vehicle area for many years • Lead state for the Connected Vehicle Pooled Fund Study • Provided support for the Connected Vehicle University Transportation Center • Developed the VCC for application development and testing • Moving towards integration with TOC operations
2
Connected Vehicle Pooled Fund Study • The Pooled Fund Study (PFS) is a partnership of transportation agencies who have established a program to facilitate the development and evaluation of Connected Vehicle applications • The program will prepare state and local transportation agencies for the deployment of Connected Vehicle technologies • The program will result in the following outcomes: – Development and demonstration of connected technology, algorithms, tools and applications – Preparation for field deployments – Development and deployment documentation – Lessons learned and identification of challenges from field deployments 3

Traveler Information Message App • DSRC or Cellular only option • Statewide deployment for cellular users • Speech recognition and reporting
11
• VCC Cloud builds dynamic traveler messages and pushes them to drivers via DSRC or Cellular • Work Zone app clusters multiple workers together if necessary • When close, locations of individual workers or clusters are streamed Road Work Ahead 200ft to VCC Mobile for higher precision Lane Shift Left display • Layout status is updated Active Work Area 400ft every 10 seconds Workers on Roadside 500ft 1000ft
Active Work Area Workers on Roadside
Trucks Entering/Leaving Roadway
Connected Worker Solutions • Integrate GPS and DSRC or Cellular into personal protective equipment • Worker and passing vehicles independently determine and exchange position information • Calculate likelihood of collision and issue alerts based on the situation • Warn the worker through audio, flashing led lights, haptic depending on urgency
Design Challenges • Lightweight and durable • Positioning accuracy – Standard GPS not precise enough for imminent crash warning – Explore alternate localization options
• Battery life / power expansion • Antenna occlusions • Communications mode – DSRC – fast, accurate, may require infrastructure – Cellular – ubiquitous coverage, no additional infrastructure, latency may be issue with alerting
• Cost to procure and maintain
Virginia’s Automated Corridor • Partnership between VDOT, DMV, Here, Transurban and led by VTTI to enable advanced automated vehicle technologies in Virginia • VDOT has committed to maintaining standards for completeness of marking and retro-reflectivity properties
15
Enhanced Pavement Markings • Current automated vehicle technology relies on pavement markings for lane keeping • Working with a number of pavement marking manufacturers • Considering a number of technology options
