Summary:
The huge financial and societal cost associated with traffic crashes and the fact that more than half of them occur at junctions, revealed the need for further research in the field of junction safety. This research aims to investigate the quantitative impact of junctions in relation to other selected parameters, on the frequency of road crashes in urban areas in the State of Florida. Mathematical models were developed with the use of loglinear analysis method for different traffic volumes in and out of junction. In addition, sensitivity analysis was performed in order to better understand the impact of selected parameters to the total number of crashes. The analysis has led to several conclusions such as that angle and left turn collisions have much higher probability of occurrence at junctions and that crashes which occur at junctions are much more probable for low and medium volumes compared to no-junctions.
