The Coalition for Cyclist Safety, formed in October 2023, aims to enhance cyclist safety and visibility through the use of cellular vehicle-to-everything (C-V2X) platforms and connectivity. As transportation accidents and fatalities continue to rise, cities and states are turning to emerging technologies like C-V2X to improve safety for vulnerable road users. This blog post aims to explain C-V2X platforms and connectivity.

What is C-V2X?

C-V2X is a communication technology that enables vehicles to interact with various elements in their surroundings, including pedestrians, bikers and city infrastructure. By facilitating real-time communication, C-V2X can enhance safety for road users by providing visibility into potential incidents or collisions. The technology allows users to receive timely alerts and warnings, empowering them to take necessary precautions and avoid potential accidents.

Benefits of C-V2X for cyclist safety

C-V2X technology offers a range of benefits that aim to enhance cyclist safety and contribute to the overall improvement of transportation systems. These include:

Real-time routing: Real-time routing information allows cyclists to choose the safest and most efficient routes. By providing up-to-date data on road conditions, traffic congestion and potential hazards, C-V2X helps cyclists make informed decisions and avoid dangerous situations.

Road condition monitoring and hazard warnings: With C-V2X, cyclists can receive immediate alerts and warnings about road conditions and potential hazards, including potholes, construction zones or road obstructions. C-V2X is intended to ensure that cyclists are aware of situations ahead, and able to take appropriate actions to stay safe.

Traffic flow optimization: C-V2X facilitates the optimization of traffic flow by coordinating the movement of vehicles and cyclists. By sharing real-time information about road users’ speed, direction and intentions, C-V2X allows for smoother traffic flow, reducing congestion and minimizing the risk of accidents caused by abrupt maneuvers.

Digital visibility of other road users: C-V2X provides cyclists with enhanced visibility of other road users, including vehicles, pedestrians and infrastructure. This improves situational awareness, allowing cyclists to anticipate the actions of other road users and react accordingly. For example, if a vehicle is approaching too closely, C-V2X can alert the cyclist, prompting them to adjust their position or take evasive action.

Cyclist detection: The technology can detect the presence of cyclists, and provide relevant information to other road users. This feature is particularly useful at intersections, where the risk of accidents involving cyclists is high. By alerting vehicles to the presence of cyclists, C-V2X helps prevent collisions and ensures the safety of vulnerable road users, significantly improving cyclist safety. Real-time information, alerts and warnings provided by C-V2X enable cyclists to make informed decisions and confidently navigate the roadways. As cities and states embrace the technology, it has the potential to make transportation systems safer and more cyclist-friendly.

Collaborative efforts and challenges

The Coalition for Cyclist Safety aims to expand globally by exploring collaborative industry approaches. Automotive manufacturers like Audi and technology companies like Bosch are advancing C-V2X. Audi uses the technology for “safety critical” communications to warn drivers about potential collision threats. Bosch focuses on integrating bicycles into the V2X ecosystem, enhancing cycling safety by providing digital visibility to other road users.

Challenges persist regarding the timeline for regulatory requirements and widespread C-V2X deployment. Regulatory considerations and collaboration among stakeholders are crucial for broader adoption. The Federal Communications Commission (FCC) plays a key role in finalizing rules that stipulate the regulatory requirements for deploying C-V2X in the 5.9 GHz transportation safety spectrum. Automakers are seeking regulatory assurance to guarantee that C-V2X technology in vehicles complies with operational standards.

Additionally, the FCC must establish rules to mitigate interference from unlicensed Wi-Fi devices in adjacent channels of the wireless spectrum, because such interference could jeopardize the transmission of safety-critical messages. These regulatory requirements provide the necessary framework and assurance for stakeholders to invest in and deploy C-V2X technology.
