Centralised Bus Priority System Dublin Public Transport Interface Module (DPTIM)
Background • D ublin P ublic T ransport I nterface M odule. • Building on existing SCATS infrastructure. • Centralised system - No extra onsite equipment necessary. • Virtual Detector configuration. • No extensive civil works required. • No additional cost to quantify performance of bus services for other projects. • Allows for network bus priority – multiple traffic junctions. • Project consists of DPTIM Interventions, Signal Optimisation and Light Civil Work.
