General location of project.

Project Highlights

The project will set up two types of communication systems:

1. For transit vehicles: Roadside infrastructure will use radio-based communication to share information with devices on transit vehicles.
2. For all other road users: Roadside infrastructure will use cellular communication to share information with cellular devices.

As part of the project, several applications will be used to provide information and alerts to road users through their mobile devices when they approach upgraded intersections:

• Signal Phase and Timing: The current traffic signal phase and remaining green time is displayed on a driver’s mobile device as they approach a signalized intersection.
• Transit Signal Priority: Signal timings are optimized for Wolfline buses in real time to ensure that they stay on schedule.
• Connected Eco-Driving: Drivers receive alerts to modify their speed, which reduces fuel consumption and emissions.
• Pedestrian in Signalized Crosswalk Warning: Drivers receive alerts when a pedestrian approaches and enters a crosswalk.
• Mobile Accessible Pedestrian Signal System: Pedestrians can “press” the pushbutton at a signalized intersection remotely via mobile device, and receive cues to safely navigate the crosswalk.
• Red Light Violation Warning: Drivers receive alerts if, based on their speed and the signal timings, the driver is expected to travel through an intersection during the red phase. Pedestrians receive alerts if a red light violation is expected to occur, or is occurring, while they are in or near a crosswalk.
• Speed Warning: Drivers receive alerts to reduce their speed.
• Work Zone Warning: Drivers receive alerts that there is a work zone ahead, and to reduce their speed accordingly.

How CV Technology Works

CV technology communicates messages between vehicles, including transit, and pedestrians by way of infrastructure and mobile devices. People can download a mobile app associated with this project that is wirelessly connected to 27 signalized intersections near the N.C. State campus in Raleigh. The app, called YU2X collects real-time data from the technology at these intersections to provide road users, including pedestrians, cyclists, and drivers, with alerts to improve traffic operations and safety near the N.C. State campus. Download the YU2X app from the Apple Store for iOS devices or Google Play for Android devices.
