METRAS is the research group of INTRAS (Research Institute of Traffic and Road Safety of the University of Valencia) specialized in the methods and practical applications of the Measurement, Evaluation, Analysis and Data Processing of TRaffic Accidents and Road Safety.

Research lines

  • Measurement and evaluation of the human factor in traffic and road safety
    • Studies for the evaluation of the transport users' behaviour and attitudes from several methodological approaches:
      • Psychometric and survey approaches
      • Observational and field studies
      • Experimental and in laboratory
    • Cross-cultural adaptation and validation of international instruments of psychological measurement of the drivers (DBQ, MDSI, etc.)
