By developing Sitraffic® Concert, Sitraffic Scala and Sitraffic Guide we have createda traffic center platform that integrates the hitherto separate worlds of traffic manage-ment, traffic control and parking guidance. Our new Sitraffic traffic center platformis based on a simple idea: The function modules run on a shared basis and can be expanded or combined at any time with further modules. This allows the successive realization of a wide range of scalable applications, from entry-level solutions fora limited number of field devices right up to complex, integrated traffic management systems, in step with the city’s budget and changing demand.

All modules of our end-to-end traffic center platform use a shared data pool. This makes the different traffic planning and control tasks easier and saves time because it eliminates the need for multiple data entries and potential error sources. Anotheradvantage of the shared platform is the uniform user interface used for differentapplications.

And thanks to their standardized communication interfaces, all Sitraffic systems can be smoothly linked up with existing technical installations. For the municipal authorities this means maximum investment security because any installed traffic infrastructure remains operational.

Our new user interface mimics the workflow in the traffic center for each application and can be flexibly configured to fit the requirements of specific tasks. This makes our traffic center systems intuitive and easy to use, providing the operator with allimportant information at a glance.

For all central applications, the Sitraffic traffic center platform uses a commonbasis for the operation of the function modules for traffic management, traffic control, parking guidance, traffic planning and link-up with third-party systems. All modules are fully synchronized witheach other and access a shared data base so that maximum transparency and consistency are guaranteed.

Modularity allowscustomized solutions

Since the function modules can becombined across different traffic applica-tions, the user is offered the necessary flexibility to implement individual,customized solutions – no matter ifthe desired functions belong to the traffic computer landscape or are part of traffic management.

On the following pages you will find the description of the most importantfunction modules.

Operational monitoringThis module continually receives and pro-cesses operational and status messages from all connected sensors, actuators and subsystems. In case of a failure or fault, the system provides structured and – where appropriate – automated pro-cedures for efficient message processing, secure archiving and immediate for-warding of fault messages to servicetechnicians, if required. The goal isto initiate the fault clearance process as soon as possible.

GIS mapThe user interface is equipped with adigital vector map, which shows allobjects including their static and dynamic data on a city map. The objects are organized in layers that can be displayed and hidden as desired. This convenient function enables the user to monitorthe current traffic situation as well as the operational status of all field devicesand to carry out operator control actions directly from the map.

Data managementThis module creates the foundation for meaningful statistics, historic reports and traffic planning analyses. A range of raw and aggregated data (measured values of various types) from different sourcesare permanently stored in the measured-values archive following plausibility checks, standardization and, if required, the generation of substitute values.

Highly secure Web-based operation (CWP – Customer Web Portal)The Customer Web Portal allows the safe operation of the Sitraffic traffic centers via an Internet connection and a standard Web browser. Password protection and mobile PIN assure the highest industrial security level.

Sitraffic Office: Planning and data supply of traffic signalsSitraffic Office is the first completely inte-grated software system for all applications in the area of traffic signal installations, from planning to data supply – for traffic computers and controllers including the corresponding traffic actuation in Sitraffic PDM(e) or Sitraffic SL(e) for intersections right up to the model-based adaptivenetwork control system Sitraffic Motion. Sitraffic Office provides planners, software engineers, operators and service technician with all required tools with direct access to the shared data base. The integrated administration and versioning functions are setting new standards in terms of process quality.

Data consistency is one of the features that make Sitraffic Office unique because it eliminates the need to enter datamore than once and substantially reduces the risk of errors. For instance, planning data are directly available for simulations and can also be used as the basis fordevice-specific additions without double entries, redundant data sets or incon-sistencies. Further advantages offered by the central data pool are the integration of intersection, link and network planning as well as the possibility for several users to work on the same project at the same time.

Sitraffic TASS for situation-actuatedsignal program selectionTASS (Traffic-Actuated Signalplan Se-lection) is based on a predefined set of recurrent traffic situations such as “High inbound traffic volumes” or “Stadiumaccess,” each of which has been assigned an optimal signal plan. The automatic recognition of the current traffic situation requires a strategic detection system. Threshold values and specific algorithms allow the identification of the currentsituation and the subsequent activation of the associated signal plan. The integra-tion of environmental values allows theimplementation of environment-related traffic control measures.

Sitraffic Motion for model-based,traffic-actuated signal controlSitraffic Motion MX (Method for Optimiza-tion of Traffic in Online Networks) uses measured values to assess the current traffic situation, and innovative algo-rithms to calculate the optimal signalprograms to be sent to the relevant traffic signal installations. All tasks related to the network are carried out on the central control level. As traffic flows are opti-mized on both the local and the central level, the system can react very quickly and effectively to any changes in thetraffic situation, even in case of strong fluctuations in traffic load. Sitraffic Motion is also a useful tool when it comes to environmental protection: The dynamic adaptation of coordinated green phases (Greens Waves) during morning and afternoon peak hours has a substantial measurable effect on fuel consumption and emissions.

Quality managementThis module monitors traffic signal switching states and parameters such as waiting times upon pedestrian or vehicle green requests, as well as travel timesof public transport vehicles. Values in excess of predefined thresholds are indicators of deteriorating traffic sig nal switching quality. The detailed quality analyses available in the module make targeted improvement measures possible.

VisualizationThe visualization function serves to display current and historic switching states of individual traffic signal instal-lations, including their coordinated green phases. With this tool, the signaling state at a specific moment in the past can be verified, for instance for a detailed analysis of traffic-actuated control processes.

StatisticsSitraffic Statistics offers comprehensive options for the statistical analysis of data from all connected sensor types. Statistical reports include lists and graphs such as peak hour patterns, flow-concentration diagrams, daily time graphs or annual time graphs of daily traffic volume fluctuations.

Sitraffic Scala:Modules for traffic control

Traffic situation detectionThe detection and visualization of thecurrent traffic situation is a key element in the operation of any traffic management center. The traffic situation detectiontool collects, checks and analyzes data from various sources. Due to our thorough traffic engineering experience and know-how, we know exactly how to turn the measured values into useful information for the operators in the center andthe connected control and informationsystems.

Incident managementNot all data relevant for traffic controlcan be detected automatically. To roundout the data base, additional traffic-related information needs to be entered, edited and completed via a traffic in-formation editing workstation. Trafficnews generated on the basis of detector data, for instance, can be supplementedwith directions provided by the policeor information on certain additional factors such as planned major events. For roadworks management, the system can automatically take over relevant geo-graphical data from the road authority’s data base into the traffic data base.

The information entered via the trafficinformation editing workstation is a factor in the definition of suitable trafficmanagement measures, such as general strategies, alternative route suggestions and adaptive network control, and isused for travel time calculation and road user information.

Travel timesNew technologies and processes enable the direct recording of route-related data, in particular travel times. Such dataare often a much more precise indicatorof congestion and traffic disruptions than data from local detectors. Two different types of technologies are applied for travel time calculation: infrastructure-based detection or Floating Car Data (FCD). As either of these approaches is in a different development and test phase and offers specific advantages, the pros and cons must be carefully considered before deciding on the implementation of either system.

Data fusionIn general, the data used for the de-scription of the current traffic situationcome from multiple sources and differ in terms of content, geographical detail,provision interval and quality. The fusion of these data will help enhance overall data quality, for instance in terms of completeness, accuracy and updating frequency – for optimized traffic control, traffic guidance and traffic information. Meaningful data fusion includes the evaluation of data reliability and takes the specific characteristics of the applied detection technologies into account. For this purpose, Siemens is developing requirements-based, tailored solutions in the scope of current projects.

Strategy managementThe strategy management module serves to define the general control strategiesaccording to which the different systems and processes will work. The tool retrieve all measured values, status information and operational messages available in the system, matches them with user-definable threshold values and combines them with time constraints to define effective traffic interventions. Urban traffic data and data from surrounding speedways as well as parking, environmental and other situa-tional data can be combined in logical sequences as needed. The defined strategy is the foundation for the implementation of various measures such as “Green Waves,” dynamic direction signs or road user infor-mation using a range of media.

Sitraffic Concert:Modules for integrated traffic management

11

Parking data recordingThis module can be used to recordoccupancy data, opening hours and operational states of all connected parking facilities as the basis for situation-tailored parking guidance.

Parking guidance sign controlThe system processes the parking data and generates the input for conventional “remaining-space” indication. In addition, the parking data can also be displayedtogether with other traffic data on freely programmable information panels and the parking guidance module can be operated as part of a higher-level traffic management system. Such a dynamic parking guidance system improves occupancy and profitability of the parking facilities, reduces the volume of parking-related traffic and the resulting environmental impact and, last but not least, makes the city more attractive by enhancing overall quality of life.

Parking route managementThis module serves to define parkingguidance routes. The individual routes can be activated in dependence on data managed by other parts of the system, for instance roadworks or event schedules, ensuring that the recommendation will guide the driver on the best route to the next available parking space.

Without open interfaces, smooth data exchange between a heterogeneous array of systems or the link-up of fielddevices from different manufacturers anddifferent periods would be impossible. The use of interface standards ensures maximum ease of integration. TheSitraffic family of traffic center systems has full command of all these standards, ensuring effortless interoperability.

OCPI (Open Content Provider Interface)Via this open interface, the Sitraffictraffic centers can exchange a wide range of data with the connected systems.The system can take over, for example, traffic bulletins, detector data, operational equipment status messages, data onroadworks, parking, the environment and the general situation; or send control commands to subsystems such as variable message signs or 3rd-party traffic computers.

Siemens ensures that the OCPI interface always remains fully upward and down-ward compatible across multiple software versions. This system stability guarantees investment security for our customersand enables long-term use of established interface converters.

Sitraffic Canto (Communication in advanced newtechnology in outstations)Sitraffic Canto is a proprietary standard that Siemens is making available forlicensing by other manufacturers in order to meet the customer’s requirements for an open system. With Sitraffic Canto, Siemens ensures full operability ofa heterogeneous field device landscape because this system provides an especially powerful method for center-to-fieldcommunication and can even be used to connect existing older controllersto modern traffic centers. It is compatible with all transmission technologies:fiber-optic cable, LAN, OTN, GPRS andInternet links.

OCIT (Open CommunicationInterface for Traffic)OCIT has been defined by a committee manned by the different system providers and is a widely used standard in the area of traffic computer systems and traffic light installations. It exists in two versions: OCIT-O (outstations) for communication with the field units, and OCIT-C (center to center) for communication betweencenters.

OCIT-O is a universally applicable inter- face that is not restricted to a specific communication medium. This interface serves to safely supply, control and monitor all device functions via remote access.

OCIT-C are standardized interfaces between central components and systems. The OCIT-C standard encompasses theformer OCIT-I process data und OCIT-I sup-ply data interfaces and covers virtuallyall interface needs in traffic management.

VDV (Verband DeutscherVerkehrsunternehmen)The VDV (Association of German Transport Companies) defines the contents of the telegrams used for local public transport prioritization. These telegrams containthe log-on and log-off messages of public transport vehicles and are radio-trans-mitted to the intersection controllers.The local traffic-actuated control routineprocesses this information and triggers the corresponding public transport priority scheme.

TLS (Technische Lieferbedingungfür Streckenstationen)The technical supply conditions for out-stations – TLS – describe a communica -tion standard for interurban highways. Via the TLS interface, the system receives traffic information, currently displayed VMS contents and general and environ-mental data that can be used as additional input for urban traffic control.

TMC (Traffic Message Channel)TMC is a radio standard for the transmission of traffic bulletins to car radios. Via this interface, the traffic management system passes on traffic information directly to a broadcasting station.

DATEX IIDATEX II is a European standardizationinitiative for various traffic data and traffic information applications. The Siemens center supports communication via this standard, depending on the project.

In every city there are numerous traffic-related systems that are operated inde-pendently of each other and often by different operating companies or public bodies, for instance the traffic light systems run by the civil engineering office, the transport authorities’ operational control centers, the fire brigade’s control center, publicroadworks administration systems, event management centers or the dispatch offices of taxi companies. All these systems hold valuable data that could be put to gooduse in the scope of an overall strategic traffic management. A system that is to provide optimal traffic control and guidance needs to have access to the scheduled dates, times and locations for major cultural or sports events or important roadworks,for instance. Thanks to their open interfaces, our control center systems can draw from all these data pools, bringing even such extremely heterogeneous system land-scapes together under one informational roof – as essential input for the definition of efficient traffic management measures.

The Sitraffic traffic center platform has been designed to communicate with a widevariety of systems that the individual modules draw upon.

Synergiesthrough integration

Strategic traffic management

Traffic flows can be influenced in various ways and by various means: Trafficlight switching plans can prioritize certain direction lanes depending on the timeof day or the specific situation; variable message signs can be used to adapt speed limits in dangerous situations, to open up additional lanes or recommend alterna -tive routes; traffic information systems support road users in choosing the best route and means of transport or plan their travel time.

Sitraffic traffic management centersoffer valuable tools for mastering the complex interaction between thetraffic center, the variety of data sourcesand the actuators and for synchronizing and coordinating the different measures. The Strategy Management module can be used to specify the trigger values for defined packages of measures, factoring in all available relevant data. This coordinated method ensures that all available actuators in a city are activated in a targeted manner to defuse critical situations and master traffic overloads.

Coordinated strategiesagainst congestion

Major traffic information platforms in Germany

Siemens is extensively involved in the three most important trafficinformation platforms in Germany. Their immense scale in terms of spatial coverage and technical and administrative complexity turns these projects into prime examples of the enormous capabilities and potential of today’s innovative technologies.

In response to congestion, hazards,accidents, critical weather conditions or excessively high emission values, the system can initiate control and guidance measures and provide road users with timely information via radio broadcasts, Internet and/or roadside informationpanels.

Our tools even support the necessarycoordination between the various public bodies responsible for different trans-port networks, for instance municipaland motorway authorities, trade fair companies, port and airport authoritiesor stadium management, so that coor-dinated strategies can be implemented to steer the entire traffic and transportin the area.

Intermodal traffic management:Optimal use of existing infrastructureFor the optimal utilization of the capacity of the entire transport infrastructure,in particular in conurbations having to cope with high traffic volumes, theintermodal approach to managing the transport system is gaining in importance. Individual capacities, current traffic load of the network, disruptions in privateand public transport and information on the transfer points between privateand public transport are the backbone of intermodal traffic management.Intelligent control algorithms then enable the best possible use of the existinginfrastructure for accommodating current mobility needs. Concrete measures are,

for instance, the provision of constantly updated numbers on the occupancy of Park&Ride facilities or of public transport departure times or travel time com-parisons via various media.

Environmentally conscioustraffic management: Keeping an eye on air qualityWind, weather and industrial emissions cannot be influenced by traffic control or guidance measures, of course. But effi-cient traffic management can signifi -cantly reduce the pollutant load caused by trucks and passenger cars (exhaustgases, abrasion, dust resuspension). Whenever the total pollutant load risesnotably and approaches the legallimits, the responsible authorities need to take immediate, efficient measures,for instance rerouting of individual traffic flows or closure of certain zonesfor certain vehicle types.

Effective air quality improvement isonly possible if the current pollutant load and distribution is known. As thenew Sitraffic traffic center platformincorporates the required environmental models, it can be used to record andmonitor immission levels across the entire area. On this basis, remedial measurescan be initiated right when and where they are required.

For the operator, the ease of use of the Sitraffic traffic centers is an essential feature. The system must provide the user with clear and constantly updated informationon the traffic situation and with the right tools for immediate intervention. For this reason we keep optimizing the graphical user interfaces of our traffic center systems.

With the latest version of our traffic center platform, we have even gone one step further: The graphical user interface adapts to the processes and activities in thecenter. This application-oriented approach of reflecting the operational processeson the user interface makes system operation easier and more transparent. Improved grouping of system functions, the new screen management function, selectivedetachment of individual screens from the main frame, fast switching betweendifferent contexts, the possibility to define individual cockpit layouts – all this adds up to a system that can be handled intuitively after only a short training period.

Additional key advantages are the uniform user interface layout for all trafficapplications and the shared data base for all tools.

Intuitive userinterface, uniform handling

User interface & operation

We keep improving the graphical userinterfaces of our Sitraffic systems to make the user’s tasks ever easier and more transparent. The latest version of ourtraffic center platform has been equipped with numerous new features for added system handling convenience. While we kept the basic layout, we perfectedthe grouping of the system functions in navigation areas and introduced thepossibility of organizing individual screens in a cockpit layout according to the user’spersonal preferences. Open screensare embedded in a main frame and can be selected via the function tree.

Faster navigation thanks todirect object accessA click on an object automatically opens the corresponding drop-down menu offer-ing specific operation and information choices. An “object” can be any traffic-related entity, for instance an intersec -tion, a car park, a strategic measurementstation, a variable message sign, a road-works site or a route section. The screen layouts for detailed representation use the same structure for all objects and serve as user interface for both systemoperation and parameterization. The objects, including all details, can alsobe listed in tabular form, offering multi -ple filters and sorting functions for thepreparation of comprehensive synopses.

A uniform user interface layoutsaves timeAll traffic applications are operated viaa uniform user interface. In addition, the Sitraffic Office software suite providesa number of valuable tools that support the intersection-related tasks of the traffic engineer, the control center operatorand the service technician alike. As all tools access the same data base, data need to be entered only once, whichsaves time and eliminates potential error sources.

GIS maps make orientation easyThe network layout map is based on a digital Geographical Information Sys -tem (GIS). This means that each object is displayed at its exact geographicallocation. Dynamic objects are alwaysrepresented by self-explanatory icons, with the icon’s layout or color changing with the objects’ status or operational mode. For parking facilities, for instance, the system can display not only theoperational status, but also bar graphsdetailing the occupancy rates. The logical zoom function ensures that the network layout contains only the level of detail that is currently required and can be displayed clearly at the selected scale.Detail depth can be individually defined for each city and each user. Another clarity-enhancing feature is the “tool tip” function: When the mouse cursor pauses on an object, an information box pops up that displays the associateddynamic key data stored in the data base.

Operation made ever easier

Convenient access to all informationavailable in the systemIn our traffic centers, the users caneasily retrieve and clearly display detailedinformation on all connected objects, access object status information andinitiate measures. Where necessary,the user can adapt specific parameters and open diagrams or reports for detailed monitoring of individual systems. Theintuitive handling facilitates the opera -tor’s tasks and saves time.

And the clear structure and detailedinformation enable very fast and targeted intervention, if required. The openOCPI or OCIT-C interface allows easyconnection of subsystems supplied by other manufacturers. The interface can be used to exchange data, control sub-systems and supply strategies.

Besides technological solutions, Siemens also offers a wide range of services for the traffic sector. For optimal alignment with the customers’ requirements, our serviceportfolio is just as modular and flexibly scalable as our traffic center technology.

With our innovative financing, maintenance and planning services as well as attrac -tive operator models, we help take the strain off municipal budgets and ensure thereliable operation of all technical systems.

Our Sitraffic traffic centers are, of course, perfectly covered by our extensive service portfolio. Some services have even been specifically developed for our trafficcenter platform. One such special service is the possibility for municipal authorities to use traffic center functions without having to build and operate a traffic center of their own. “Application Service Providing” is the name of this new Siemens service that allows local authorities to regain some of the financial freedom of movementthat was lost to ever tighter budgets over the past years.

Support that really makes a difference

Services & support

Application Service Providing (ASP): Renting functionality instead of buying a traffic centerThe demand for traffic centers thatcan be used without requiring extensiveinvestments or binding resources on the part of the local authorities keepsrising. To meet this demand, we havedeveloped our new ASP model.

Under an ASP contract, customerscan use selected functions of a SitrafficScala traffic computer system running in a Siemens-operated traffic center.The customers access the system from their PC via a secure Internet connection.Traffic controllers and communication hardware and connections within the fielddevices remain under the customers’responsibility.

Affordable solutions alignedwith individual requirements

Operator models: Using always the newest technology – at calculable costsIn many cases it makes economic senseto entrust the actual operation of certain traffic infrastructure elements to acompetent partner. And thanks to specific resources and comprehensive know-how, Siemens is just such a partner.We make the performance of traffic infra-structure and/or street lighting more transparent for a city’s authorities. In the scope of such operator models, Siemens takes over the responsibility for bothsystem operation and the continuousupgrade and modernization of devices and systems. This means that thecustomer can always rely on state-of-the-art technology – at fixed and calcu lable costs.

Financial Services: Technology andfinancing facilities from a single sourceIn times of limited budgets in particular, financing solutions are of increasingimportance for Siemens customers. With our Performance Contracting or Energy Contracting models, we offer our cus-tomers virtually self-financing ways of realizing the necessary updates of their technical traffic infrastructure. Our range of “classic” financing solutions reaches from consulting and insurance rightup to equity and debt financing schemes. As international provider of financingsolutions in the business-to-business sector, Siemens finances infrastructure, equipment and operating resources.In Germany alone, Siemens FinancialServices has more than 10,000 customers, including small and mid-sized companies as well as well-known multinationalcorporations, local, regional and national authorities and other public bodies.

Service contracts:Safety at a predefined levelCustomized service and maintenancecontracts help ensure that each solution is serviced exactly to the extent desired by the customer. Local authorities withtheir own professional services team may only need to be reassured that in anemergency, all necessary spare parts will arrive within a defined time frame. Others need us to provide service techniciansas well, while some customers willwant to delegate the full responsibility for their traffic equipment, expectingguaranteed availability of the system 24 hours a day, 365 days a year. As everycustomer has a different idea what con-stitutes the ideal service level, we have developed contract modules that can be combined exactly as the customer needs and desires, and complemented by additional services as required.

Training: TÜV-certified and basedon practical experienceOur hands-on training courses will help newcomers as well as experiencedspecialists expand and deepen their traffic engineering knowledge. Besidesdetailed know-how on our productsand systems, we provide the participants with information on the latest devel-opments in the traffic technology sector.The training program includes generalknowledge classes and seminars on detection or controllers as well as units on traffic center systems or pay-and-display machines or a series of training courses on traffic planning and project devel-opment. By the way, our training units are the only ones in the market that have been certified by the German TÜV.
