Locus Inspections 

Our UK-wide experts strive to complete locus inspections in a timely manner. When at a locus we will survey and record all pertinent features and, where relevant, conduct further investigations linked to, for example, intervisibility during the hours of darkness, or fields of view that are unique to a certain vehicles. We can tailor our inspections to mirror the collision circumstances.

Plan Drawing

Following a locus inspection we can prepare accurate scaled plans of the locus. The contemporary software used for creating a scaled plan can also be used to develop the plan from a two-dimensional piece of paper into a three-dimensional scene.

Creation of three-dimension modelling provides the ability to determine likely fields of vision, from a driver’s/rider’s/pedestrian perspective as well as offering the impartial review of a witness’s potential view. We have found that three-dimensional modelling provides direct benefit in cases involving large vehicles, such as LGVs and PSVs, to establish a driver’s potential to see vulnerable road users such as pedestrians and cyclists.    


Using our locus survey data, or in the case of desk-top review cases, being provided with scale plans or satellite imagery, we are able to create an animation to enable the easy visualisation of what is often complex vehicle/pedestrian movements, prior or post of a collision event.

We are also able to generate vehicle animations based upon vehicle EDR data, thus the vehicle movements are reflective of the actual collision, not an interpretation. Animations created using EDR data highlight vehicle dynamics such as speed, degrees of yaw, the driver steering, throttle and brake application, as well as the intervention of ADAS systems.
