122 APPENDIX B: Work Zone Intrusion Technology Taxonomy The work zone intrusion technology taxonomy provides a system of classification of available WZITs according to specific characteristics of WZITs and their intended application and use. The taxonomy presents an organized list and mapping of WZIT, roadway, work operation, worksite condition, and technology adoption descriptors. The technology is intended to assist decision- makers with selecting appropriate technology for use in a work zone based on the features of the technology, work zone, work operations, and roadway conditions.
