Cutting casualty rates and making roads safer is a priority for local and national governments around the world. Accident rates in the UK have continued to decline over recent decades, thanks to a combination of high publicity campaigns and a wide variety of safety improvement schemes across all scales of the road network. However, Casualty Reduction Targets serve to highlight that preventing accidents will continue to be an important priority.

TRL's accident related software is applicable both to the UK, to improve existing schemes and to identify deficiencies, and to countries where accident prevention schemes are perhaps only in their early years.

iMAAP is the new generation MAAP - a software product TRL has been supplying both in the UK and worldwide since the 1980's and the most widely used off-the-shelf crash data system across the world. MAAP has undergone a complete review and the result is a brand new version which provides a better fit with today's technological environments, offering additional capabilities required by the professionals who use it.

Accident models are also included in the following products:

ARCADY: calculates accident rates and accident types at roundabouts and mini-roundabouts, based on traffic demand and roundabout geometry.

PICADY: calculates accident rates and accident types at unsignalised priority intersections (T-junctions, crossroads and staggered junctions, each of which can be in a rural or urban setting), based on traffic demand and junction geometry.

OSCADY: calculates accident rates and accident types at isolated signalised junctions (T-junctions, crossroads and staggered junctions), based on traffic demand, junction geometry and signal properties.
