The documented work ranges from a rail-disruption system that recommends recovery actions, to connected-vehicle pilots, autonomous-shuttle research, infrastructure inspection, traffic prediction and cybersecurity. Some examples are operating systems; others are pilots, demonstrations or research projects. A connected-vehicle or automated-driving project is not automatically an AI deployment, so each example below identifies what the source actually establishes.
The inventory contains 35 documented examples and project areas drawn from U.S. Department of Transportation (USDOT), UITP, DLR, ITS America and National Academies material. It is not evidence that exactly 35 projects use AI, nor that every project remains active. The strongest measured AI-specific result is Hitachi Rail’s recovery recommendation system for JR East: a proof of concept reported by UITP cut resolution time for comparable major incidents by about 50%, from roughly two hours to one.

What counts as an AI transportation deployment?
Transportation agencies use several overlapping labels. Artificial intelligence generally means a model learns patterns from data to classify, predict, recommend or control an action. Intelligent transportation systems (ITS) is a broader category covering sensors, communications, software and control; an ITS project may contain no AI. Automated vehicles describe a driving capability, not necessarily the machine-learning methods behind it. A credible inventory therefore records the AI method when the source names one, and says “not stated” when it does not.
Maturity also matters. An operational system is in routine service. A field trial or pilot has been tested with real users or traffic but may be limited in duration or geography. A demonstration proves a concept in a controlled or bounded setting. A research project is developing methods, processes or evidence rather than offering a mature service.

35 documented examples, pilots and project areas
The table separates measured outcomes from objectives and identifies whether the available description establishes AI specifically. The USDOT evaluation summarized 23 broader ITS deployments (six connected-vehicle, 12 digital-infrastructure and five automated-vehicle cases); those cases should not be reclassified as AI without project-level evidence.

Where AI adds value across transportation
Prediction and early warning
Prediction is the common thread in crash-risk modeling, congestion analytics, signal timing, maintenance and freight routing. The model turns historical and live data into a forecast, but a forecast is useful only when an agency can act on it: dispatch a crew, retime signals, warn a driver or reserve a maintenance slot. Accuracy, latency and false alarms matter more than the label “AI.”
Recommendation and decision support
The Hitachi Rail example is a decision-support system rather than an autonomous controller. Dispatchers remain responsible for the decision while the model searches approximately 3,000 historical failure and malfunction records for comparable events. This pattern is attractive where expertise is scarce and the cost of delay is high, because it preserves human authorization while reducing search time.

Perception and automation
Automated-driving demonstrations use sensors and software to perceive lanes, vehicles, workers, signs and emergency activity, then plan and execute actions. The USDOT portfolio shows why context matters: rural roads without markings, work zones, first-responder scenes and ports create different edge cases. A demonstration in one setting does not establish safe operation in all settings.
Rank #3
Infrastructure and cybersecurity
Computer vision, sensor analytics, digital twins and anomaly detection shift AI from the vehicle to the asset or network. Agencies can prioritize bridges, pavement and inspection work, while security teams can look for abnormal V2X traffic. These applications still require labeled data, maintenance records, secure interfaces and procedures for acting on a model’s alert.

Reported percentages are project-specific. The USDOT evaluation attributed a 13% travel-time reduction and 10% fuel reduction to the Alpharetta school-bus pilot, a 35% travel-time reduction to St. Petersburg signal integration, a 90% lower collision risk and 80% fewer hard-braking events to the Connecticut cloud-alert deployment, and a 42% reduction in average crashes per year in Wyoming (up to 28% for truck traffic). The source describes these as connected-vehicle or ITS outcomes; it does not establish that the systems used AI.
Only the Hitachi Rail figure in this set is explicitly tied to a named AI model and a before/after recovery-time comparison. It came from a proof of concept using JR East records for 2020–2022 and concerned significant incidents that typically took about two hours. Treat it as one operator’s result, not a general rail or AI benchmark.
Recommended Free Tools
- Ask who measured the result and during which dates.
- Check whether the comparison is against a baseline, a control group or a modeled estimate.
- Separate an objective, such as “reduce congestion,” from a measured outcome.
- Confirm that the cited technology actually includes AI rather than sensors, communications or fixed rules.
- Check geography, fleet, weather, traffic mix and operating constraints before transferring a percentage elsewhere.
What organizations need before deployment
- Define the operational decision. Specify whether the system will recommend a recovery action, change a signal, schedule maintenance or control a vehicle.
- Inventory usable data. Check historical depth, labels, missing values, sensor calibration, privacy restrictions and the frequency at which data arrive.
- Set a human-control policy. Decide who can accept, override or reject a recommendation and what happens when the model is unavailable.
- Test in the target context. Include rare events, work zones, emergency scenes, poor weather, unusual traffic and cybersecurity failures rather than relying only on clean demonstrations.
- Measure the right baseline. Record delay, fuel, crashes, hard braking, maintenance downtime or other agreed metrics before rollout, then report uncertainty and side effects.
- Monitor after launch. Data distributions change when routes, fleets, construction or regulations change. Retraining, audit logs and incident review are operational requirements.
Bottom line: transportation AI is real, but maturity is uneven
Real AI deployment exists alongside a much larger ecosystem of connected-vehicle, automation and research projects. The clearest operational proof in this inventory is the rail-disruption recommender reported by UITP. KIRA remains a 2023–2026 research effort, and the USDOT ADS examples are demonstrations rather than evidence of universal autonomous service. For every claimed “AI deployment,” identify the model, the operator, the setting, the maturity stage and the measured result before drawing a conclusion.
