Better roadway data. Stronger funding cases.
Capture high-quality roadway data wherever your city needs it, not just at intersections, and turn it into clear, compliant reports backed by real-world evidence instead of one-time studies or stitched-together proxy datasets.
Measuring the street,
not just the intersection.
Most street-safety measurement relies on intersection cameras, summary counts, and point-in-time snapshots. Cumulant reads continuous behavior across the full block.
Blind spots from intersection-focused camera placement
Intersection cameras cover the signal zone well, but the mid-block crosswalk further down the block sits entirely outside meaningful coverage. Activity there goes unmeasured.
Coverage extends beyond the intersection node
Cumulant measures the corridor itself, so the mid-block crossing becomes part of the same readable system rather than a gap between isolated camera views.
Counts are not behavior
A count can register a cyclist, a vehicle, and a pedestrian as three discrete events, while missing the fact that they are sharing the same constrained lane space at the same moment.
Behavioral context turns raw counts into street intelligence
Cumulant measures how people and vehicles occupy the street together, making proximity, interaction, and lane competition visible instead of flattening them into isolated tallies.
Static snapshots miss state behavior
A curb can appear clear or occupied in a single frame, but that frozen view misses the nuanced sequence where a passing vehicle, a blocked loading zone, and a pedestrian crossing create a near miss.
Street state changes become readable over time
Cumulant reveals evolving street state, showing how repeated loading behavior, passing maneuvers, and pedestrian movement combine into a risk pattern that snapshots cannot explain.
Cumulant turns street activity into measurable evidence.
