National Highways utilises the UTMC system (Osprey) and is used for CTM (Collaborative Traffic Management) in SE and YNE. Osprey interfaces with local authority equipment and is utilised by operators to set strategies that enhance traffic flow on diversions and establish strategic variable message signs within the jurisdiction of the authorities. Daily, operators use Osprey to actively manage traffic entering and exiting the SRN by manipulating traffic lights at junctions with predefined settings. These settings have been shown to yield up to a 37% reduction in journey times at certain locations.
