ITS UK has published a summary of the activities of each ITS UK member that is working on connected and autonomous vehicles capability. Transport Research Laboratory TRL, TRW Conekt and Arup feature, and TSS is included for its current work on the development and application of Aimsun to the assessment of autonomous and connected vehicles.
The Aimsun API Extension and MicroSDK package allows users to replace default behaviours and settings with bespoke control algorithms to run connected vehicle communications either V2V or V2I. Additionally Python scripting means you can automate repetitive tasks and obtain specific outputs such as indicators of traffic performance (capacity maximization), safety (collision reductions), economic efficiency (fuel consumption) and environmental impact (emission reductions), among others.
TSS provides a mature tool in terms of evaluating connected vehicle technologies, response plan evaluation and, in Aimsun Online, a Decision Support System in a TMC for providing simulation-based prediction.
Additional outcomes of Aimsun-based modelling, in its live (or quasi-live) application in the connected vehicle framework might include co-operative centralised route choice calculation and also evaluation (pre-evaluation and testing or real time) of tailored response plans enabled by connected vehicles.
Aimsun’s flexibility means these investigations of impacts, such as capacity and emissions, will not just apply to motorway/platooning/road train implementations, but also to far more complex systems that may ultimately be applicable to urban areas.
