Modernize Road Safety With Physical Intelligence

Cumulant automates both the collection and interpretation of roadway safety data - powered by ground-truth infrastructure sensors - so you can focus on ensuring safer roads for everyone.

When safety decisions affect real streets and real lives, cities need data that reflects what actually happens on the road, from the road.

  • Traffic behavior is measured directly from infrastructure sensors rather than inferred from aggregated mobility data.

  • Lane-level trajectories, interactions, and safety events are captured with the spatial and temporal detail required for modern safety analysis.

  • Because the data reflects real observations from the street, safety metrics and risk analysis are grounded in measurable behavior - not statistical approximations.

Everything cities need to collect, interpret, and act on roadway safety data.

Everything needed to conduct modern safety studies - from automated ground-truth data collection to AI-driven risk analysis and incident reporting. Cumulant replaces manual field studies and fragmented tools with a single platform that continuously measures and interprets real traffic behavior.

How It Works

Hardware Automatically Captures Traffic Data

Roadside sensors continuously capture real-world traffic activity, including vehicle movement, pedestrian activity, and multimodal interactions - either through Cumulant hardware or existing infrastructure feeds.

Physical Intelligence Interprets Multimodal Interactions

Cumulant’s AI models process raw sensor feeds in real time, identifying trajectories, conflicts, and safety-relevant behaviors while organizing the data in a centralized project dashboard.

Data Becomes Safety Intelligence

The platform transforms observations into clear analytics, visualizations, and reports that help cities identify risk, evaluate treatments, and understand safety performance over time.

Safety Data You Can Trust

We collect data directly from the street using infrastructure sensors—capturing real traffic behavior instead of relying on aggregated signals or statistical models.

01

Ground-Truth Measurements

Lane-level trajectories, speeds, and multimodal interactions are measured with high spatial and temporal precision, providing reliable inputs for modern safety studies.

02

Engineering-Grade Accuracy

Every insight is backed by observable events and sensor data, allowing planners and engineers to review, validate, and confidently defend their safety decisions.

03

Transparent and Verifiable
