LRT priority within the SCATS environment in Dublin - a traffic flow simulation study

摘要

This paper focuses on the feasability of operating a Light Rail Transit (LRT) priority system within the environment of an existing Urban traffic Signal Control System (UTC) in Dublin. The city uses the Australian UTC-System SCATS (Sydney Co-ordinated Adaptive Traffic System). So far no LRT is running in Dublin yet, but the objective of the study was to establish the degree of LRT priority to be achieved within the existing SCATS UTC. The study was carried out using the microscopic traffic simulation model VISSIM. The simulations clearly show that LRT priority is possible within SCATS on a tactical (local) level at each controller.
