Case Studies

Indentifying crash causation

Single or multiple vehicle accidents... pedestrian collisions… day or night… Crashes can happen anywhere, anytime, and it's the challenge to Jamieson Foley to investigate and accurately determine how and why they happen.

Identifying and evaluating factors involved in a crash requires complex forensic analysis of events, circumstances and time sequences. It involves the application of a rigorous scientific methodology. This methodology, together with other inputs - the instructing brief, the quality of the physical evidence, the statements from crash participants and witnesses, enable
the forensic engineer to bring the crash events “to life” and thereby ensure fair rulings within our court system.

Examples of factors that Jamieson Foley engineers have identified for recent cases have included:
change of camber (superelevation) in mid-corner contributing to a truck running off the road
misleading signposting on a winding rural road causing a motorcyclist to run off the road
substandard median widths causing pedestrians to trip into the path of a car
misleading combination of vertical and horizontal curvature causing wrong placement of a vehicle on the road
maintenance fault which caused a loss of control
inadequate signposting for roadworks causing a loss of control of a vehicle on loose material
inadequate power of low beam headlights to see pedestrians ahead at night
external fittings on a truck which have come loose during a collision with a car, fatally injuring the car occupants
substandard street lighting design contributing to a pedestrian collision.

International activities

Jamieson Foley & Associates have undertaken numerous International Activities including New Zealand, Singapore and Qatar. We work on building better pedestrian and cycle paths to help reduce the number of accidents.
