Build Safe Streets and Roads for All with V2X solutions
More than ten thousand road fatalities happened at intersections last year in the United States, most of them in urban areas. Speeding and multi-vehicle crashes also greatly contribute to poor road safety.
Some road infrastructure owners have already started to plan and build smart intersections to improve road safety. Now they are getting a huge boost from the Safe Streets and Roads for All (SS4A) program which will provide a total of $5 billion over five years to prevent roadway deaths and serious injuries.
Now you can learn how vehicle-to-everything (V2X) will help these developments with better results. Commsignia offers end-to-end V2X solutions and recommends these 5 steps to build a comprehensive and future-proof system. This will allow you to keep the number of road fatalities and injuries at a permanently low level.
1. Generate more data
Vehicles generate a vast amount of information, and V2X provides real-time access to this valuable data source. Installing V2X on-board units (OBU) on fleets allow operators to be up-to-date with the vehicles’ statuses.
Smart sensors like cameras, radars and lidar can be integrated with V2X roadside units (RSU) so traffic safety experts will know more about non-connected road users. Pedestrians and two-wheeled vehicles are better protected if infrastructure owners and operators have real-time information on their presence.
2. Connect your assets
Roadside units turn signalized intersections into smart intersections. Traffic light controllers connected to RSUs broadcast accurate status information to road users, so they can choose the right speed to avoid running red lights.
Variable Message Signs display dynamic speed limit and road hazard information for drivers. The same information can be delivered through V2X messages over a much larger area, directly to the vehicles’ dashboard. It will be harder to miss critical information!
3. Use data to plan safe streets
Commsignia Central visualizes data in an easy-to-understand interface. V2X and sensor data help road authorities better understand traffic offenses and conflicts in an area. They can even find situations that almost become accidents. In addition to collecting data, Commsignia Central allows road operators to create and upload V2X messages to the RSUs.
The built-in management tools ensure the continuous operation of the V2x infrastructure by monitoring the roadside equipment.
4. Optimize signal timing for equity
Urban maintenance such as roadside mowing, garbage collection and snow plowing can make drivers impatient. V2X applications allow priority emergency vehicles and publicly owned fleets to request a free pass at signalized intersections. Faster moving fleets create less disruption in traffic and lower the risk of crashes.
V2X can make public transport more predictable and attractive, because buses can catch up with the schedule with a few longer green lights. A similar approach can be taken to promote walking and cycling. After detecting the presence of pedestrians and cyclists, traffic signals can quickly turn green or provide longer crossing time. This will make active mobility more convenient.
5. Prepare the infrastructure for self-driving
Self-driving vehicles can cause fewer accidents than human drivers, but their algorithms need to use huge amounts of data. V2X provides accurate information, therefore self-driving cars make better decisions with less data processing, and they will move faster and safer on the roads.
