SISTM (Simulation of Strategies for Traffic on Motorways) is a microscopic motorway simulation package that is owned by the Highways Agency and has been developed to evaluate methods of reducing congestion. The software has been continuously enhanced since the first release in the early 1990s, in order to model a wide range of applications, provide additional output measures and improve the graphical display of the model running. This report presents a review of past use of SISTM and considers possible future options for the package so that the Highways Agency can decide how the software fits in with their plans. SISTM consists of a suite of programs which include both 2D and 3D representations of the motorway being modelled. It has been used in many motorway studies, mostly for the Highways Agency, including setting of parameters for the Controlled Motorways section of the M25 (J10 to J16) and improving the modelling of shock waves. It has also been used with hypothetical networks in order to study a greater range of different scenarios including in-vehicle systems, such as Autonomous Intelligent Cruise Control. This report describes possible enhancements that could be made to the software, in particular to the exhaust emission and noise modelling, and discusses the options for the future development of the package.
