2. UK / Industry / Mobility / Traffic Solutions © Copyright Siemens plc 2009 April 2009TraffexPage 2 Fuel for thought The reduction of congestion and maximising of network capacity has always been a key objective for traffic managers Recent research by the AA highlights the additional impact queuing traffic and congestion have on emissions

3. UK / Industry / Mobility / Traffic Solutions © Copyright Siemens plc 2009 April 2009TraffexPage 3 Keeping traffic moving Reducing congestion and keeping traffic moving offers significant benefits in minimising CO 2 emissions Effective network management requires a strategic plan which considers both control of traffic and information dissemination Solutions must be expandable and sustainable to accommodate future growth

4. UK / Industry / Mobility / Traffic Solutions © Copyright Siemens plc 2009 April 2009TraffexPage 4  Single solution for integrated network management and control  Modular design allows the system to grow with future network demands  Flexible core system tailored to individual requirements  Latest UTMC standards for ease of integration and expansion Benefits of UTMC and Comet

5. UK / Industry / Mobility / Traffic Solutions © Copyright Siemens plc 2009 April 2009TraffexPage 5 How does Comet help to reduce congestion? Comet provides a flexible, expandable solution which can grow as the demands of network management evolve Strategic network monitoring and control Information availability Tactical control Links to external agencies www Comet

6. UK / Industry / Mobility / Traffic Solutions © Copyright Siemens plc 2009 April 2009TraffexPage 6 Network management - Strategic control  Strategic response plans are generated which can be operated manually or automatically as required  Commands can be sent to any externally connected UTMC system or module within Comet to simply and effectively respond to any unplanned incident or planned events  In Sefton, Comet allows the network to be managed efficiently without operator intervention – ideal for events at Aintree which can cause significant congestion in Sefton  Additionally, congestion is reduced by using the most appropriate method of control dynamically rather than the traditional time of day approach

7. UK / Industry / Mobility / Traffic Solutions © Copyright Siemens plc 2009 April 2009TraffexPage 7 Network management – Journey time monitoring Journey time monitoring using ANPR allows accurate, up to the minute information to be included in the network management process The live journey time data supports both network management as well as network performance trend analysis JTMS offers a rich source of data for both live and analytical operations Inherent accuracy in JTMS with ANPR provides high quality, reliable data

8. UK / Industry / Mobility / Traffic Solutions © Copyright Siemens plc 2009 April 2009TraffexPage 8 Network monitoring – Performance analysis Comet UTMC provides the ideal source of data for network performance monitoring In addition to ANPR derived data, UTMC makes it easy to integrate other sources of data to be used for network performance analysis Comet enables facility usage to be analysed in conjunction with congestion data to further optimise strategic management plans

9. UK / Industry / Mobility / Traffic Solutions © Copyright Siemens plc 2009 April 2009TraffexPage 9 Information availability Variable message signs play an important role in providing key traffic information at decision points along the route The benefits of VMS were proven in a survey undertaken as part of the original ROMANSE project where an average of 17% of drivers modified their route as a result of messages on VMS VMS information is a powerful weapon in the armoury of the traffic manager but reliability and accuracy of information is critical

10. UK / Industry / Mobility / Traffic Solutions © Copyright Siemens plc 2009 April 2009TraffexPage 10 Better information before travelling Live traffic and travel information from the Internet linked directly to Comet provides accurate and reliable data for deciding when and how to travel Quality and accuracy of information is critical to the usage of the service Information published must consider the location and time of use Linking directly to Comet minimises operator workload by rapidly disseminating information

11. UK / Industry / Mobility / Traffic Solutions © Copyright Siemens plc 2009 April 2009TraffexPage 11 Tactical control with SCOOT Traffic signals Update on SCOOT MC3  Benefits of congestion supervisor Details of Service Pack 1  SCOOT MC3 continually monitors the SCOOT network, searching for inefficiencies and congestion  Identifies frequently congested intersections and provides diagnosis for  Faulty detectors and resultant problems  Overloaded junctions  Wasted capacity  SCOOT MC3 Service Pack 1 includes additional features for dealing with congestion caused by exit blocking and enhanced pedestrian strategies

12. UK / Industry / Mobility / Traffic Solutions © Copyright Siemens plc 2009 April 2009TraffexPage 12 Sustainable traffic solutions Power consumption of signalling equipment is another factor in the overall emissions related to traffic management solutions As part of the overall carbon footprint of traffic control equipment, the whole manufacturing, installation and maintenance process must be considered The use of ELV and LED technology allows much more efficient and lower power devices to be utilised with corresponding reductions in carbon footprint

13. UK / Industry / Mobility / Traffic Solutions © Copyright Siemens plc 2009 April 2009TraffexPage 13 Sustainable traffic solutions Local manufacture of equipment in the UK reduces significantly the carbon emissions associated with shipping Siemens manufactures over 2000 traffic control devices each year at our factory in Poole, Dorset

14. UK / Industry / Mobility / Traffic Solutions © Copyright Siemens plc 2009 April 2009TraffexPage 14 Are you sitting comfortably? Streetscape presentation is increasingly seen as an important factor in new urban developments Reduction in street “clutter” is a key objective of many town planners
