Enhanced Safety Through Vehicle-to-Vehicle Communication
One of the major benefits of connected vehicle technology is improved road safety through vehicle-to-vehicle (V2V) communication. V2V allows vehicles to continually share information with each other regarding their location, speed, and direction over dedicated short-range communications (DSRC) technology. By broadcasting this data 10 times per second, vehicles can predict potential collisions and warn drivers through audible or visual alerts.
For example, if a vehicle is preparing to turn left at an intersection and does not see an oncoming vehicle in its blind spot, the oncoming vehicle can alert the turning vehicle that a collision is imminent. V2V communication also helps avoid rear-end collisions. If traffic suddenly comes to a stop, the connected vehicles behind can receive advance notice to slow down before reaching the congestion. According to the U.S. Department of Transportation, V2V technology has the potential to address approximately 80% of crash scenarios involving unimpaired drivers.
Improved Traffic Flow with Vehicle-to-Infrastructure Integration
In addition to V2V, Connected Vehicles will benefit from vehicle-to-infrastructure (V2I) integration. V2I allows connected vehicles to communicate with nearby transportation infrastructure like traffic lights, variable message signs, toll booths, and parking spaces equipped with dedicated short-range communication technology.
For example, traffic lights can broadcast signal timing information so vehicles approaching an intersection know precisely when the light will turn yellow or red. This helps smooth traffic flow and prevent rear-end collisions caused by unexpected light changes. Variable message signs allow transportation officials to notify drivers of accidents, congestion, construction detours, and other incidents in real-time.
Connected vehicles will also be able to reserve parking spaces at their destinations before arriving. Using V2I, drivers can view available spots and pay for parking electronically to bypass entry and exit barriers. Combined with autonomous driving advances, shared vehicles could drop-off passengers curbside without circling for parking. All of these integrations between vehicles and infrastructure enhance mobility while reducing congestion and emissions.
Advanced Driver Assistance Systems
Connected vehicle technology will supercharge existing driver assistance systems and enable an array of new safety features. Advanced driver assistance systems (ADAS) that use sensors, cameras and automated controls are already helping avoid accidents in isolated scenarios. However, their capabilities are limited without an external communication network.
Access to real-time connected vehicle data allows ADAS to detect emergent risks beyond a vehicle's sensors like oversized loads, emergency vehicles, hazardous materials spills and more. ADAS can also leverage collective intelligence from all connected vehicles on the road. For example, if one vehicle slides on black ice, connected vehicles hundreds of feet behind receive an immediate alert to slow down before reaching the hidden hazard.
Other future ADAS innovations enabled by connected vehicle data include left turn assist, cooperative adaptive cruise control, intersection movement assist, remote vehicle disabled prevention, and automated emergency braking in all directions. Connectivity opens the door for sophisticated self-driving systems without human interaction. Together, V2V, V2I, and ADAS advancements could revolutionize safety, accessibility, and productivity on our nation's roadways.
Expanded Mobility for All Road Users
Connected vehicle technology has enormous potential to expand transportation access for vulnerable road users like pedestrians, bicyclists, and transit riders. Vehicles will be able to detect and alert drivers to people or objects that may be difficult to see. Wearable connectivity or smartphone integration allows pedestrians and bicyclists to share their real-time location, path and speed with connected vehicles within the area.
Public transit vehicles like buses, shuttles, and rideshare services guided by vehicle connectivity can offer more flexibility compared to fixed routes or schedules. On-demand services can redirect to pick-up people along their travel path using real-time data. Connectivity also allows routing and utilization optimizations based on patterns and needs across entire transportation networks.
Better right-of-way cooperation between all road users lays the groundwork for expanded shared mobility models and first-last mile solutions through innovations like bike-sharing, scooter programs and integrated payment systems. Ultimately, connectivity allows modernizing transportation to better serve people of all ages and abilities. When implemented responsibly, these technologies could improve accessibility and affordability for disadvantaged groups.
Data Privacy and Security Challenges
As with any rapidly developing technology, connected vehicles bring risks that require prudent policy and oversight. The collection, storage and sharing of sensitive location and operational vehicle data raises serious privacy and cybersecurity issues that demand responsible solutions. Some main challenges include:
- Preventing unauthorized third-party access or hacking of connected vehicle networks
- Establishing transparency and user consent for data collection and usage
- Anonymizing driver and travel patterns to protect personally identifiable information
- Ensuring equity and inclusion regarding when, how and by whom connected vehicle data can be used
- Addressing potential increases in distracted driving or over-reliance on automation
- Mitigating risks of new criminal uses of connectivity like convoying or geo-fencing
Overall progress requires an informed public, reasonable regulations and standardized industry practices that win public trust through strong security protocols and privacy-centered design. With care and cooperation among leaders, the promise of connected vehicles can transform transportation for safety, sustainability and shared prosperity in a responsible manner.
