Microsimulation
Evaluating network performance and measuring the effect of change such as increased traffic flow, new infrastructure and developments requires a versatile and realistic tool set. By using microsimulation tools combined with traffic and network management expertise Siemens offers a turn key solution through modelling, design, implementation and on-street validation.
In the current policy and funding climates it has become more critical than ever to test and prove schemes in a cost effective manner before commitment to project budgets and implementation of network amendments.
Using a model for network analysis gives the ability to quickly amend network demands, layouts, and configuration. The tools can readily provide statistical network wide results as well as promote accessibility to a range of audiences through 3D graphics, video outputs and graphic presentation techniques.
The construction of any urban microsimulation network will invariably incorporate signal control and Siemens’ expertise in the intricacies of controller workings and signal optimisation provides accuracy to modelled networks and junctions.
Applying experience of ITS solutions, design and signal control methodology to modelling studies enables a full assessment of scheme and technology options prior to deploying an operational solution This can include elements of junction remodelling with reference to national design guidance, comparison of different control methodologies and adaptive control or the operational benefits of providing bus priority or additional infrastructure.
Anticipating how the scheme can be implemented and the phases of operation and maintenance, keeps scheme completion at the forefront of models assessments and recommendations, to ensure the resulting recommendation is readily transferable to the on-street scenario. Siemens’ modelling projects include informed advice on scheme design and peripheral appraisal of implementation requirements and projects can also involve liaising with traffic control centres and network operators to better understand the network requirements and preferences and smooth the transition between transport modelling and implementation.
Siemens’ SCOOTLink to connect a UTC controller to microsimulation models allows scenarios to be tested within a real life context. Fully simulating adaptive control provides a more realistic representation of network control strategies and offers a detailed appraisal and analysis of strategies to aid in the decision-making process.
Looking longer term, strategic network planning is an integral part of traffic management and has been pushed to the forefront following the Traffic Management act of 2004. Modelling with adaptive control offers the network manager a more realistic tool for network and event management. Demonstrating and simulating the effects of SCOOT and MOVA within a model provides a safe environment in which to test strategies and makes the perfect implement for training and developing skills in SCOOT and MOVA validation.
Traffic Solutions’ comprehensive range of modelling services includes network and junction microsimulation modelling in Aimsun, Vissim or S-Paramics packages. Our model audit and support service includes commenting on model build, fitness for purpose and helping clients understand and extract information from studies submitted in support of 3rd party schemes. Our dedicated modelling team can also be used to provide additional resources at crucial stages during model development and scheme design.
