Slow Down! TTI Researchers Recommend Strategies for Slowing Drivers Around Work Zones
Making drivers comply with work zone speed limlits can be a difficult task. In 2000, there were 9500 crashes within a work zone and speed was the major cause in 42% of those crashes. The problem is … [Read more...] about Slow Down! TTI Researchers Recommend Strategies for Slowing Drivers Around Work Zones
Assessing the Benefits of Smart Work Zone Systems
Smart work zones (SWZs) are being deployed around the United States as a way to inform drivers dynamically about traffic conditions within a work zone. SWZs use sensors to detect traffic flow … [Read more...] about Assessing the Benefits of Smart Work Zone Systems
