The objective of this study was to test three traffic control devices---white lane drop arrows, orange rumble strips, and the CB wizard alert system---for their effectiveness in improving merging, and reducing speed and speed variance at an interstate highway work-zone in Missouri.; ...
Work zone impacts on traffic operations are magnified when project durations are extended. Conventionally, work zone traffic control plans are developed to address work zone impacts. This study evaluated various merge control strategies at interstate work zones peak and off-peak traffic conditions and ...
“Got that. Emergency. Clear to land. Runway. Two. Three,” the air traffic controller responded to the pilot, in audio obtained by The Associated Press. “We’re clear to land, but we’re not gonna make the runway. We’ve lost both engines,” the pilot calmly replied. ...

This is intuitive as vehicles are much more under control and less likely to skid on dry road conditions compared to other road surface conditions. A similar result was found by other studies for median barrier crashes [58,67]. Traffic barrier crashes in snowy weather were found to be ...
Temporal distributions of the PAHs (average mean 9.2 nanogram/cubic meter ±9.0 std) were compared to traffic count, and meteorological and pollutant data collected at the near roadway station. Using the meteorological data (i.e., wind speed and direction vector data), wind roses were created ...
