Forensic tachograph analysis: Microscopic analysis, route traces, driver's hours & regulations. Our expert in this field comes from a very experienced background including air accident investigation, driving 38T Large goods vehicles, operating his own haulage company and Tachograph Analysis Bureau. In that time Mr Coltman, on average, analysed over 1000 Tachograph charts per week, which equates to a career total in excess of 750,000 charts. In addition, Mr Coltman wrote his own computer software for chart analysis and report production writing an 'industry standard' book on the interpretation and application of the EC hour's regulations. Mr Coltman continues to act as an advisor on interpretation and application of ERC hour's regulations to one of the main analysis bureaux in the UK. Mr Coltman has been accepted as an expert witness during Court proceedings in all levels of Court. Mr Coltman now operates as a Consultant in all aspects of Tachograph construction, function, calibration, installation and testing of Tachograph recording equipment, chart analysis and route tracing to forensic level using a calibrated microscope. Speed of vehicle movement, taken second by second from speed trace, is logged and translated into distance and acceleration (+/-) rates using standard velocity formula. These figures can then be applied logically to each situation with an aim of adducing what did happen, what did not happen and what could have happened.
