What could some V2I technologies look like?
-
Innovative, intelligent infrastructure is needed to support a digital ecosystem. There is a need for increased redundancies that help drivers, cameras, and sensors more easily sense and decode rules of the road.
Here are just a few emerging technologies that can be used to improve roadways, mobility, and safety.
• Advanced Road Markings: We need pavement markings that are visible to humans and machines in any road condition.
Pavement lane markings work with automated vehicle sensors to detect lines outside the vision-based spectrum, improving lane detection and traffic safety in even the most extreme weather conditions.
• Smart Signs: We also need directional signage that is visible to humans and machines in any road condition.
Retroreflective signs provide better readability, which results in more accurate navigation and faster decision-making for both drivers and automated vehicle systems. In addition, smart signs are compatible with traditional signage.
• Wireless Communication: There is also a need for wireless communications that connect directly to vehicles, quickly helping identify construction zones and potential safety hazards so vehicle mobility and traffic flow can improve.
A DSRC Multi-Channel Test Tool is an independent multi-channel listening device that provides vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications. The test tool is an unbiased 3rd party resource, used to decode standards and connected vehicle requirements; SAE J2735, IEEEE 802.11p and IEEE1609.
Redundancy: increasing safety and enhancing mobility
-
No single system will guarantee safety. Safety will only increase if all vehicle systems are working together to improve the readability of pavement markings, traffic signs, and temporary traffic control signs and devices.
Redundant systems take over when GPS isn’t able to work, such as in a tunnel, or when pavement markings aren’t visible to a vehicles’ camera.
Think of systems working together to improve mobility and safety for everyone. If buildings are blocking a satellite and GPS isn’t working, or if snow has covered pavement markings, a LiDAR sensor or camera can provide the redundancies necessary to keep traffic moving efficiently, improve drive time and vehicle safety. Congestion is greatly reduced. People are more mobile. People get where they need to go faster—and more safely.
State-of-the-art vehicles require state-of-the-art infrastructure. Improving infrastructure through redundancies is how we drive innovation, increase safety, enhance mobility, and create roadways of the future.
