What are the current and emerging technologies for intersection safety management?

One thing I found useful is the use of signal coordination to manage speed along a corridor and reduce the severity of injuries. Adaptive systems can help control arrivals along the corridor, allowing vehicles from uncontrolled cross streets to enter the flow of traffic.

Improving traffic signal timing can greatly reduce congestion and the likelihood of accidents at intersections. Using real-time data, engineers can adjust timings dynamically to ensure smoother traffic flow and minimize risky stops or aggressive driving.

With vehicles communicating directly with traffic infrastructure, we’re stepping into a new age of intersection safety. Connected vehicle technology allows real-time sharing of location and speed data, enabling cars to warn each other of hazards or sudden stops ahead

I need additional studies to prove the benefits of CV technologies. I am concerned about the breach of personal data although I believe road safety is of higher importance.

Autonomous vehicles have the potential to drastically change intersection safety by removing human error, which is a major factor in crashes. As AVs become more common, intersections may be designed with them in mind, integrating more advanced safety protocols.

Proper design of intersection geometry can improve sightlines and reduce vehicle conflict points. Small changes like adding roundabouts or curb extensions can lead to significant safety gains, especially in high-traffic urban areas.

I believe that adequate geometric design meeting all standards and requirements will contribute to improve road safety. Design must align with prevailing speed for horizontal and vertical curves. Cross sections must consider the road classification. Sight distances must be adequate to allow for safe stopping, passing, and merging. Adequate sight distances at intersections may reduce areas of conflicts. Proper design channelizations will channel flow and reduce conflicts at intersections. On local streets, a road diet may be the solution to improve safety along a corridor.

Analyzing safety performance is crucial for understanding which intersections need improvement. Using data-driven approaches, engineers can identify patterns of high-risk behavior and implement targeted interventions to reduce collisions.

With the rise of AI, IoT, and connected systems, the future of intersection safety looks bright, but also challenging. Adopting these technologies will require collaboration across sectors, adapting infrastructure, and training teams to implement and maintain new systems effectively.
