…SATURN can help.

Accurate modelling of flow metering and blocking back

SATURN accurately reflects the effects of congestion on urban road networks by explicitly modelling the impact of queues that form at a particular junctions on the capacity of those upstream ('blocking back') and the reducing flows able to travel downstream ('flow metering'). Other modelling software simply treats junctions in isolation, and therefore, without accurately reflecting the impact of queues on network performance.

Collaborate and share data between software platforms

SATURN can input and output data at the matrix, link and junction level in a multitude of different formats, allowing you to work cross-platform with other multimodal transportation software or economic appraisal tools. With SATURN, you are in control of the data.
