![]() ![]() ![]() The new ONE model will be calibrated and validated to 2017/2018 base year according to industry best practice and standards and will represent all network and ITS changes that have occurred since the previous model was built in 2014-5. ![]() Tony Dichev (Lead Transport Modeller) and Irfan Shaffi (Operational Control Manager) from TfL Network Management Directorate are the key contacts from the TfL side. Given the incredible scale and pace of change on London’s road network in recent years, TfL now needs to update not only the Base model but also its entire modelling approach, hence the decision to move from a static model to a large-scale dynamic model.Īimsun will uniquely collaborate with both the TfL Strategic and Surface Modelling teams, to deliver an integrated, large-scale, static (macroscopic) and dynamic (mesoscopic) model that covers the whole of Greater London out to the M25 perimeter. However, since then, TfL has undertaken numerous local-area calibration exercises to upgrade sections of the model on a scheme-by-scheme basis. TfL’s current London Operational Network Evaluation (ONE) Model has been calibrated and validated to 2014/5 data. We expect the delivered model and tools to bring major improvements in efficiency and process to TfL for many years to come.” We are excited to collaborate with the TfL Modelling teams to deliver the next level of modelling tools for the UK’s capital. Gav Jackman, Managing Director of Aimsun Ltd., said: “London is the only megacity in Europe, so the fact that Aimsun Next has been chosen for this project is very significant for us. Integrating modeling levels and introducing a new dynamic layer of simulation at a city-wide level will allow TfL to take a more efficient, coordinated approach to scheme evaluation, road works and traffic management.Īimsun will be exhibiting at Smarter Tomorrow The idea behind this project is not only to consolidate existing models into an integrated, multi-level platform for modelling the city’s transport-with all the efficiency, consistency and cost reduction that this implies-but also to update the model and enrich simulation knowledge. ![]() Aimsun has a long working history with TfL and its software is already licensed to TfL through the city’s Strategic Modelling Framework and the Operational Modelling Frameworks, which were put in place back in 2015 and recently extended to 2020. ![]()
