Predicting Work Zone Collision Probabilities via Clustering: Application in Optimal Deployment of Highway Response Teams

Figure 8

Numeric values indicate correlation between (continuous and ordinal) input variables and number of WZ collisions. Yellow and magenta denote positive and negative correlation, respectively. Brighter links indicate greater correlation, while less visible links imply low correlation. Unfilled tokens indicate that a variable has low total absolute correlation with other covariates [76].
