High Performance Transport Network Modeling and Simulation; HIPERTRANS

In general, the HIPERTRANS system aimed to have the following basic functionality:
- performing microscopic simulation, and having a user-friendly graphical user interface (GUI);
- interfacing capability to UTC systems and capability of working in real time;
- being able to simulate and predict the state of the road traffic; and
- achieving a high-performance computing network (HPCN) system on low cost platforms;

results
The project’s first deliverable (D1) was on the User and Systems Specifications. Subsequent milestones achieved were D2 (‘HIPERTRANS Prototype Simulator, S1’); D3, (‘Real-time Simulator, S2’); D4 (‘Predictor, S3’). S1 is useful for scientific study. S2 can be interfaced and integrated with two real UTC equipment. S3 has a faster-than-real-time capability and achieved high performance by means of cluster computing. It is able to forecast the behaviour of a real network much faster than a real-life system. The project has also produced 4 combined Management/Progress Reports (D7) at 6-monthly intervals. It has also submitted 2 other non-software development deliverables: D5 and D6. D5 reported on demonstration; and D6 reported on exploitation plans. Two test sites, Hyde in the UK and Valencia in Spain have been employed. The criteria used in selecting these test sites were that they had a suitable UTC system and were willing to participate in the evaluation of the project. S2, which has the most potential commercial benefits, was used for high-profile public demonstrations and evaluation at Hyde and Valencia.

applications
Through the application of low cost but high performance computing environments, advanced simulation technologies and industrial software production methodologies within the project, a fast, representative, flexible and visually comprehensive traffic simulation tool have become available. The HIPERTRANS systems can provide a tool consisting of a new range of facilities for transport consultants, researchers, traffic engineers and UTC centre managers. They can enable road network operators to assess the performance of their network quickly under a variety of operational conditions and behavioural patterns. Additionally, it will provide a tool for hardware commissioning and operator training. S2 and S3 can be applied in the specification, analysis, design, commissioning and operation of urban transport networks prior to the implementation of new networks and strategies, or the modification of existing ones. The speed of S3 permits faster than real-time prediction of road network behaviour to be made. It is therefore be possible for UTC operators to examine the future effect of their selected actions on levels of congestion fast enough to be able to revise and re-test the performance before selecting the best action to take. The use of this tool should now be made easy by the availability of powerful but cheap personal computers. The availability of easy-to-use software that runs on the PCs and the use of a familiar graphical user interface will facilitate this further.
The results of HIPERTRANS can help to create optimum UTC systems engineering base that can reduce costs, improve time to market and guarantee customer satisfaction. They can help to forge and strengthen stronger links between UTC manufacturers, research and technological development establishments, and local government transport teams. The participation of different UTC manufactures in this project has helped to overcome the challenges of non-interoperability of UTC systems not only in Europe but also throughout the world. By the means of the HIPERTRANS tool, consultants, researchers, UTC manufacturers, local authorities and governments can gainfully exploit traffic modeling and simulation techniques.
