Police FCIU Technical Support Services

As well as assisting with policy, and planning for road casualty reduction on local roads, TRL has a range of technical support services to deliver efficiencies when police are required to report on collisions in court cases.


When a road collision requires investigation, or police are required to give evidence in an insurance claim, there is a lot of work to do. TRL’s team of highly experienced forensic collision investigators can assist the police with investigative activities that may be more cost effective when outsourced. These tasks include:

CCTV & dashcam footage analysis

Our fixed price service will report back with confirmed speed, orientation and actions of objects, with option to create a in reconstruction model. Read more here >>

Analysis of event data

A fixed price service looking at information available from in-vehicle data such as infotainment systems, telematics products, insurance ‘black box’ trackers, airbag and restraint system modules. Sometimes the absence of event data is as revealing as the presence of data when it comes to determining a precise sequence of events. Read more here >>

ADAS technology assessment

Free advice on whether a fault or failure of an automated system caused or appears to have contributed to an incident. This service is funded by DfT in exchange for inviting officers to record pertinent information about ADAS systems known to be present on a vehicle involved in collision. Capturing this data is essential as the UK prepares for an increasingly automated vehicle parc, so that FCIU officers in turn are equipped to deal with the technologies. To access this specialist advice, please email CAVcollisions@trl.co.uk  or call 01344 770150

Event reconstruction

Using 3D simulation software: particularly for complex or multi-vehicle incidents, a high-fidelity visualisation of a collision can be extremely helpful in court. TRL are experts in combining 3D laser scan data of the scene with CCTV video, 3D vehicle models and other physical data collected by the collision response team, to recreate the chain of events based on the laws of physics.

Coordinating data sharing agreements 

These are necessary when a complex investigation needs the collation of information from the other agencies providing data or evidence sources for collision analysis. E.g. Coroners Office, Legal Representatives of persons of interest, vehicle examiners, Councils hosting local collision data about a hot spot, and other national UK collision datasets (STATS19 and RAIDS).
