Classification and Regression Tree Approach for Predicting Drivers’ Merging Behavior in Short-Term Work Zone Merging Areas
This study aims to use the classification and regression tree (CART) approach, one of the most powerful data mining techniques, to predict drivers’ merging behavior in a work zone merging area. On the … [Read more...] about Classification and Regression Tree Approach for Predicting Drivers’ Merging Behavior in Short-Term Work Zone Merging Areas
A Case Study in Spatial Misclassification of Work Zone Crashes
Studies associated with work zone crashes are often based on law enforcement traffic crash reports. Work zone crashes are typically segregated from the larger crash data set by special coding on … [Read more...] about A Case Study in Spatial Misclassification of Work Zone Crashes
