IBM Training Computers to Predict Traffic

A team of IBM researchers is working on a system that could warn drivers of congestion ahead of time. The team has combined sophisticated analytics software with a network of sensors already embedded in California roadways, according to the Associated Press. The team will use a database of past traffic tie-ups to predict what will happen in the future; one team member notes that a goal is to “give them [drivers] an idea of what this looks like 30 to 40 minutes from now.”

Metro Roadways to be Improved

The Des Moines Register reports that several metro roadways will be improved over the next few months. The Fleur Drive viaduct over the American Discovery Trail will undergo a $1.1 million rehabilitation. Beginning May 2nd, the roadway will be closed for approximately three months.

Additionally, workers will add a new access point along Northwest 86th Street in Clive. Officials expect that this project will take about five weeks to complete, with kickoff expected in June.

Finally, a stop sign will be replaced with a yield sign at a Douglas Avenue intersection in Urbandale. The yield sign will keep traffic moving faster and will help keep westbound traffic from backing up.

Speed Cameras Save Lives

A new study finds that speed cameras do in fact reduce traffic injuries and deaths. According to Reuters, the study analyzed the results of 35 studies from countries around the globe to understand the impact of speed cameras. Researchers found that, when speed cameras were present, average speeds were reduced by up to 15 percent. The number of crashes also fell when speed cameras were in place.
