Work zone safety management and research relies heavily on the quality of work zone crash data. However, it is possible that a police officer may misclassify a crash in structured data due to: … [Read more...] about Identification and Analysis of Misclassified Work-Zone Crashes Using Text Mining Techniques
Crash Analysis
Using Worker’s Naturalistic Response to Determine and Analyze Work Zone Crashes in the Presence of Work Zone Intrusion Alert Systems
Work zone Intrusion Alert Systems (WZIAS) are alert mechanisms that detect and alert workers of vehicles intruding into a work zone. These systems pre-dominantly employ two components-sensors placed … [Read more...] about Using Worker’s Naturalistic Response to Determine and Analyze Work Zone Crashes in the Presence of Work Zone Intrusion Alert Systems
