A scene visit includes a detailed examination of the area around the collision site and, if requested, a colour 3D laser survey to capture the scene geometry and topography.
The following is a list of the information / evidence that can be generated following a scene visit:
- Details and positions of any marks on the road surface including police marks, tyre marks and damage.
- A 3D point cloud of the site which can be used in CAD / 3D modelling software to accurately reconstruct the collision scene.
- Condition of the road surface.
- Damage to roadside furniture.
- Details of signs and notices leading up to the impact site.
- Locating additional physical evidence in the form of vehicle components.
- Obstructions to the line of sight.
- Details of the view available to the involved parties and also the witnesses.
- Topography of the road to determine whether there were any hidden dips / bumps.
- The gradient of the road surface which could influence the braking calculations.
- Traffic light timing / sequencing.
- The position of any CCTV cameras.
- Identification of additional witnesses.
- Light intensity reading from streetlamps etc.
