Enabling Agencies for Integration of Artificial Intelligence into TSMO
FHWA
Recognizing the increasing opportunity artificial intelligence may play to support roadway operations, USDOT FHWA has created the AI COE dedicated to providing technical resources and support to deployers. At the 2026 AASHTO Safety Summit, this poster solicited technical resources desired by deployers.
Rear-End Collision Prevention Function in Signalized intersection
Maryland
Study (pre-deployment assessment) aimed to mitigate rear-end collision risks at signalized intersections utilizing advanced lane-based, wide-range detection sensors extending Dynamic All Red Extension to optimizing the green termination time.
TIM Training and Technology Supporting Post-Crash Care
FHWA
FHWA highlights efforts to support EMS through TIM technology, training, on-the-scene tools, and vehicles. Many states have introduced TIM training and technology to bolster post-crash care.
Connecticut DOT formed a roundabout committee of professionals trained on evaluating the planning, design, and construction of roundabouts on municipal and state roads.
Systemic Countermeasures Implementation and Tracking
Virginia
Virginia DOT created a statewide inventory and tracking system for the performance of countermeasures, leading to better communication among employees and partners, and the ability to track ongoing progress.
TxDOT's video sharing platform streams real-time video from 3,000 traffic cameras to department staff, first responders, and other partners, allowing them to respond to emergency events while minimizing congestion and secondary crashes.
The nighttime fatality rate on the nation's roadways is three times higher than the daytime rate, and 76% of pedestrian fatalities occur at night. FHWA offers tools including safety countermeasures, updated and new approaches for lighting design and traffic control devices.
CTDOT uses several strategies to combat wrong-way driving, including behavioral countermeasures, a public awareness campaign, traffic signals, signs, pavement markings, and delineators.
UDOT is addressing safety and mobility at traffic signals for all road users, including snow buildup in traffic signal LEDs, wrong-way driving countermeasures, and accessible pedestrian signals. Automated performance measures allow for full situational awareness, even for vulnerable road users.
