A macroscopic model with a UK-wide zone structure, compatible with Transport for the North’s NoHAM model and with a microsimulation subnetwork covering Stockton Town Centre.

The Stockton Aimsun Model has been developed to test options for Stockton’s Future High Streets Fund bid, including the closure of Riverside — a major road within the town centre. As such, a model was needed to that was capable of testing the detailed local impacts within the town centre as well as wider strategic reassignment effects.

The solution was to build a macroscopic model that covers the majority of Stockton borough in detail, with a skeletal buffer network connecting this network to a UK-wide zone structure. This allows strategic reassignment associated with schemes to be assessed on the wider network. Cordon (traversal) matrices are then generated and used within the microsimulation subnetwork. These cordon matrices include the strategic reassignment effects but also enable the detailed local impacts of schemes to be assessed.

The modelling undertaken as part of this project has been instrumental in shaping the Stockton Future High Streets Fund proposals, ensuring that the best transport solution for the town is implemented.
