An automated system that adjusts the timing of traffic signals when buses are running late is helping to improve transit reliability along Langston Blvd.
Since late summer, county transportation officials have been using “transit signal priority” along the 5-mile corridor from East Falls Church to Rosslyn. The system extends green lights and shortens red lights when ART buses are behind schedule — resulting in a small but measurable impact.
“The goal is smarter, more reliable transit,” said Josh Drucker, transit-technology manager for the county government, at the Nov. 18 meeting of the Transit Advisory Committee.
