Artificial intelligence backs Maryland’s $50 million smart traffic signal upgrade

“By replacing 20-year-old existing controls with Smart Traffic Signals, we will have the ability to respond to changes in traffic flow, as well as traffic conditions immediately — benefiting nearly 700,000 Maryland citizens across the state,” Hogan said in a statement.
The upgrade will bring new signals to 14 major corridors around the state and follows a controversial $9 billion investment announced last month to add new lanes to three major roadways.
The technology is expected to be upgraded by the end of 2018, with the first corridor slated for improvements within a month.
