VivaCity Near Miss Detection

Real-time road safety insights and incident root cause analysis

Revolutionary Insights for Road Safety & Active Travel

VivaCity’s Near Miss detection is a road safety game-changer and a key feature of our innovative Smart Road Safety solution. With Near Miss it’s possible to detect and analyse a range of dangerous interactions that could have led to collisions, where they happen, and in real time.

How do VivaCity sensors detect near miss events?

To automatically detect near miss events, speed and path data of road users are analysed using three metrics: Proximity, Post Encroachment Time and Time to Collision.

By using not one, but three methodologies of analysis, and applying specific thresholds, it's possible to both identify near miss events and the root cause of the incident, with high accuracy and efficiency.

Make the right decisions with trusted data

Near Miss provides objective and unbiased data through consistent near miss measurements.


Quickly discover road safety hazards & intervene early

Understand where, when, why, and how near miss interactions are taking place and proactively intervene.

Case Studies

Support evidence-based decision making

Justify expenditure on road safety interventions and prove results of schemes to stakeholders.
