Methods for the assessment and prediction of traffic safety at urban intersections and their application in micro-simulation modelling. Thesis KTH Royal Institute of Technology, Stockholm.

The work presented in this thesis is concerned with the many concepts, theories and methods related to short-term traffic safety assessment. Key issues concern the validity, usefulness and potential of various traffic safety indicators as predictors of traffic accidents and related outcome severity levels. The basic hypotheses underlying the work presented in this thesis concern the relationships between and among different proximal safety indicator measures (frequencies and levels of severity) and how these are influenced by, and related to, other traffic parameters. Furthermore, it is of importance to identify how the associated concepts and methodologies can be combined with regard to the ulterior goal of establishing reliable and valid short-term traffic safety assessment methods.
