SHM is a new measure of traffic hazard, based on two main parameters:

Proximity (separation distance)
Motion (relative speed)

Unlike the rest of the industry, we measure interactions (i.e. non-collisions), shown to be effective predictors of the likelihood and severity of incidents in other areas such as civil aviation and the chemical process industry.

The Streetscope Collision Hazard Measure is:

Free of Assumptions


No other traffic safety measure in the industry does all of those at once - or comes anywhere close.


Objective | Quantifiable | Repeatable | Independent

How is Safety Quantified Today?
By Measuring Post-Collision

Existing measures all have serious limitations:
TTC, PET, ISM, RSS, IMU, AV Disengagements, Traffic Conflicts...

These trailing indicators incur pain and loss in society, and are not an ethically acceptable approach.

We Measure Traffic Interactions (i.e. Everything Before Collisions)

A continuous measure of degree of near-miss allows us to measure and compute traffic safety indicators objectively, every tick of the clock.

No more waiting for years of statistics to make the right decisions.
