Aggressiveness Propensity Index for Driving Behavior at Signalized Intersections

This paper develops a quantitative intersection aggressiveness propensity index (API) intended to capture a signalized intersection’s overall propensity to experience aggressive driving. The index is a latent quantity that can be estimated from observed environmental, situational and driving behavior variables using structural equations modeling techniques. An empirical study of ten major signalized intersections in the greater Washington DC metropolitan area is conducted to illustrate the approach. The API is shown to provide (a) an approach for capturing and quantifying aggressive driving behavior given certain measurements taken at a particular intersection, (b) understanding of the factors and intersection characteristics that may affect aggressiveness, and (c) an index for the cross comparison of different traffic areas with different features, as well as to support safety policy analysis and decision-making.
