Connectivity to Infrastructure
• Anything you can do unconnected (autonomously) you can do better connected
• Providing better information about vehicle movements to infrastructure operators (V2I)
• Providing better information and guidance about traffic, road and weather conditions to drivers and vehicle systems (I2V)
• Providing better information about vehicle movements to other vehicles and drivers (V2V)
10
Traffic Management Challenges
• Management objectives: safety vs. efficiency
• Traffic management complexity
• Architecture: vehicle-based vs. central vs. hybrid
• Roles and responsibilities of agencies
• Technology compatibility
– Vehicles
– Traffic management systems
• Methodology & innovation
• Transition & market penetration
11
Infrastructure Implications - CV
• Funding for implementation, operation, maintenance
• Communications– Fiber backhaul?
– Wireless: DSRC or other?
• Data safeguards
• Technical skill sets
• Scale of implementation unknown
• Timeframe: market penetration of equipped vehicles?
• Part of the Connected Vehicle/Automated driving environment
• Part of SAE DSRC Message set
• Provides status and time remaining in signal indications
• Applications– Red light running/collision avoidance
– Dilemma zone protection
– Ecodriving
– Dynamic mobility
• Developed and tested prototype for FHWA
New Infrastructure Requirements:
Signal Phase and Timing (SPaT)
13
• Single platform for multiple I2V applications onto a single platform– DSRC/LTE
Communications– Message Generation– SPaT/MAP Information– Positioning Correction
• Include processing power to field level decision making
New Components: Integrated
I2V Prototype

New Testbeds: Smart
Intersection Initiative
• Concept: create controlled environment (RELLIS) and real-world environment (West campus) to develop, test, and implement advanced connected vehicle traffic signal strategies.
Research signal operation, technologies, and pedestrian, bicycle, and transit interactions
Partners: Texas A&M University, TTI, and Private Sector
New Collaborations:
AERIS Eco-Signal Operation
• Part of FHWA initiative for Applications for the Environment: Real-Time Information Synthesis (AERIS)
• Evolutionary approach
• Exploring implications of sharing Eco-signal relevant transportation data
• Sharing of data between public agency infrastructure and privately owned vehicles
• Sponsor: CAMP under a cooperative agreement with FHWA
