Crash Data

Identifying Temporal Instability in Factors Causing Work Zone Crash Occurrences Using Fast Causal Inference

Finding effective countermeasures of work zone crashes requires identifying the causes of work zone crashes. Recently, several researchers have identified some evidence that the influence of factors … [Read more...] about Identifying Temporal Instability in Factors Causing Work Zone Crash Occurrences Using Fast Causal Inference

ODOT Spreads Awareness for Work Zone Safety

About 4,800 work zone crashes, which resulted in 29 fatalities, occurred in Ohio last year. Ohio Department of Transportation, the Ohio Laborers-Employers Cooperation and Education Trust, the Ohio … [Read more...] about ODOT Spreads Awareness for Work Zone Safety

NC Has Had 206 Deaths in Work Zones Since 2016. NCDOT Names Two Main Causes

The work zones crashes in North Carolina  in 2021 was up 5% from the previous year. The North Carolina Department of Transportation estimated more than 50% of those crashes involved speeding or … [Read more...] about NC Has Had 206 Deaths in Work Zones Since 2016. NCDOT Names Two Main Causes

Agile Work Zone Management Based on Connected Vehicle Data

Peak period lane closures can result in significant queueing on major interstates. Many state agencies thus have a lane closure policy in place based upon historical time of day and day of week … [Read more...] about Agile Work Zone Management Based on Connected Vehicle Data

Assessment of Commercial Truck Driver Injury Severity Based on Truck Configuration Along a Mountainous Roadway Using Hierarchical Bayesian Random Intercept Approach

For the last decade, disaggregate modeling approach has been frequently practiced to analyze truck-involved crash injury severity. This included truck-involved crashes based on single and … [Read more...] about Assessment of Commercial Truck Driver Injury Severity Based on Truck Configuration Along a Mountainous Roadway Using Hierarchical Bayesian Random Intercept Approach

Characterizing Interstate Crash Rates Based on Traffic Congestion Using Probe Vehicle Data

Crash reduction factors are widely used by engineers for prioritizing safety investments. Work zones are routinely analyzed by the length and duration of queues. Queue detection warning technology has … [Read more...] about Characterizing Interstate Crash Rates Based on Traffic Congestion Using Probe Vehicle Data
