  • In the multivariate analysis, the variables were adjusted among them.

  • *Refers to the direction of vehicles going north-south and vice versa, and east-west and vice versa; therefore, if these converge at an intersection, this is called four ways, and so forth.

  • †The hierarchy is based on the road width, number of lanes and road capacity.

  • ‡Estimated on a 5 min or 300 s lapse.

  • aOR, adjusted OR.
