What is "smartbus"

SmartBus is a network of bus services in the city of Melbourne, Australia. Overseen by Public Transport Victoria, the network comprises nine key cross-town and orbital bus routes around Melbourne. Key aspects of the service include more frequent services, extended hours of operation to include late evening and Sunday services, improved timetable information at bus stops, roadspace priority along certain routes and priority at particular traffic lights. The SmartBus network was expected to reach 370 kilometres by 2012.
