LaneMarker AI Studio · Safety Analysis

Safety analysis that starts with the crashes on your road.

LaneMarker pulls crash records onto the network you drew — snapped to the roadway, not scattered across the county — then forecasts expected crashes, ranks countermeasures and writes the safety memo.

What it does

Built for the way engineers actually work.

Crash data on the map

Fatal and injury crashes are matched to the roadway you are studying, with severity, type and timeline charts.

Predictive analysis

Highway Safety Manual Part C predictive methods estimate expected crashes per intersection and segment.

Countermeasures with CMFs

Compare treatments by crash modification factor and expected reduction, then carry the chosen ones into the plan.

SS4A-ready outputs

Collision diagrams, crash summaries and safety action plan content for Safe Streets and Roads for All.

How it works

3 steps. One map.

  1. 01

    Load crashes

    Bring in public crash data or upload your agency’s crash file.

  2. 02

    Analyse

    Severity, type, timing and expected-versus-observed comparisons per location.

  3. 03

    Recommend

    Rank countermeasures and export the safety memo or action plan sections.

FAQ

Safety Analysis — questions

Where does crash data come from?
Public national fatal-crash data is available out of the box, and you can upload state or local crash records for full coverage.
Can it support an SS4A application?
Yes. LaneMarker produces the crash analysis, high-injury locations and countermeasure content an SS4A safety action plan needs.
