Driver & Vehicle Visibility Assessments

Computer modelling can determine what is available to be seen by a particular driver in a particular vehicle, based on laser scanning of the incident vehicle or by using pre-existing 3D models. This includes direct (through windows) and indirect (via mirrors) vision.

 

Driver & Vehicle Visibility Assessments

Visibility is one of the most important factors for drivers, particularly for drivers of large vehicles such as HGVs and buses. In terms of vehicle design, the direct vision of the driver is influenced by factors such as the location, size and shape of the windows. Indirect vision is influenced by factors such as the position of the various classes of mirrors.

A vehicle visibility assessment enables a comparison of the vehicle modelling to other incident information (such as forensic CCTV analysis, physical evidence or witness accounts) allowing determination of whether the parties involved were available to be seen and hence whether the incident could have been avoided.

Our visibility assessment experts use the latest technology, including total stations and laser scanners, to establish collision locus and vehicle measurements, with the ability to measure complex scenarios where 3D models are needed. 3D laser scanning provides the ability to collect measurement data at speeds up to 976,000 points/second in a 360o view. Multiple scans are tied together to create a single, complete, colour 3D environment with hundreds of millions of points.

Our highly experienced team developed many of the processes used to assess and represent visibility zones in 3 dimensions and have published research papers and presented at conferences in this area.
