GUIDELINE FOR THE DEPLOYMENT OF Traffic Conditions Information (Predictive and Real Time) [TIS-DG03)]

SERVICE DEFINITION

Traffic Conditions Information Services means the provision to road users of traffic conditions on identified road segments of the TENT-T network and interfaces. This predictive or real-time information could be released on-trip and pre-trip. Different media could be used for its provision: roadside information panels (VMS), websites, radios/TVs, mobile phones, navigation computers, etc. The service is dedicated to road users and may include common information as well as personalised (individual) information, it focuses on road traffic information.

SERVICE OBJECTIVES

Traffic information is useful before and during a journey To plan if / when / how to make the journey To minimize the impacts of traffic congestion on peoples journey

Thus the drivers knowledge of traffic conditions will make a significant contribution to improving environmental performance, efficiency, including energy efficiency, safety and security of road transport.

EUROPEAN DIMENSION

Ideally traffic conditions information should in the European dimension provide continuity across neighbouring regions and between member states. Thus the purpose of this Guideline is to develop the existing services towards having a truly European (pan-European) service and to assure an adequate service quality (Level of service). The European continuity aspects are the service coverage (geographical and time availability), the continuity as regards content across corridors and TEN-T network and interfaces, and the language-independence characteristics.

1. General Framework 1.1. General Service Description

The service includes pre-trip as well as on-trip real-time and predictive information on the road traffic conditions for a specific network. The intent is to assist drivers and travellers to use the traffic network in a more efficient and safer way. This is done by changing or influencing routes or modes, e.g. to minimize the impacts of traffic congestion on peoples journey and thus to reduce travel time.

The aim of the service is to:

inform the driver / traveller about the current traffic conditions in order to support him finding the best way to travel,

provide the traveller with a pre-trip forecast of information about the potential road traffic conditions for a specific road network at a point in time to be selected by the traveller,

inform the driver / traveller well that he can travel in a more calmer and safer way.

Relevant information for this service is e.g.:

status of the current traffic situation

current changes in the traffic conditions

congestion

Further information which are relevant and affects the traffic conditions will be described by the other TIS Deployment Guidelines (DG), e. g. road blockings will be tackled by the Deployment Guideline for event and warning information.

The service is dedicated to the driver / traveller and may include common information as well as personalised (individual) information. The information provision can follow pre-defined strategies or management plans which are in operation of the road authorities or management centres.

A main focus of this deployment guideline is the Internet-based pre-trip and on-trip traffic information on dynamic maps, with road sections coloured according to defined categories of Level of Service. This type of display gives the traveller an instant and language independent picture of the current traffic situation.

In addition, national, regional or local broadcasters may also provide traffic forecasts to mass audiences. Through the exploitation of smart and SMS based mobile phone technologies a personalised (individual) service can be provided.

Further examples for carriers are:

mobile devices (e.g. personalized real-time traffic conditions information)

RDS-TMC / TPEG radios (common real-time traffic conditions information)

conventional traffic radio (common real-time traffic conditions information)

VMS traffic condition information, e. g. on congestion on the network (roadside traffic conditions information)

Relevant complementary information is:

on the causes and durations of traffic disturbances, e.g. incidents, accidents, weather or events such as construction sites

on the consequences on traffic conditions, e.g. delays

recommendation of alternatives (e.g. re-routing or modal shift)

historic traffic information used for predicting traffic flows



TIS DG03 - 01 October 2010 8/25

This relevant complementary information is not content of the current Deployment Guideline and will be covered by other DG.

This document is part Bii and a supporting guideline of the main document Guidelines for Traveller Information Core European Service - Summary Document.

1.2. Contribution to EasyWay Objectives

A detailed description of the contribution to the EasyWay objectives of all TIS core services is provided in table 1 of the Guidelines for Traveller Information Services Summary (DG01). The contribution of this guideline has a real strong and direct impact and relationship to altering departure times and decisions to travel, and to more effective routing decisions. The particular contribution of Traffic Condition Information Services is described below.

1.2.1. SAFETY

Information about the traffic conditions has an impact on road safety. Due to the provision of predictive and real-time information to the drivers / travellers, they can react to find the best way to travel and to bypass critical road segments / areas of the network, respectively. Drivers / travellers who are well informed about the traffic condition decrease the risk of accidents.

1.2.2. NETWORK EFFICIENCY

With predictive and real-time information about the traffic condition the network efficiency can be influenced positively. The information can be used for recommendations so that the traffic load can be diverted inside the road network or shift to public transport.

1.2.3. ENVIRONMENTAL IMPACT

The provision of information can help to reduce congestions length, to harmonise traffic flow and to reduce disturbances in the whole road network. This helps to reduce negative effects of traffic on the environment, e.g. to decrease the CO2 emission.

1.3. State-of-the-Art

Information concerning traffic conditions being / will be provided to end-users in different ways. They will be given by the following channels:

Roadside guidance systems (e.g. VMS)

Internet portals

Navigation systems

Mobile devices (e.g. mobile phones, PDAs)

RDS-TMC / TPEG

Radio

Videotext

The named channels are described in detail in the following sections and best practices are presented in Appendix 1. These examples do not represent the state of the art all over Europe. They are provided by Easyway Partners, in order to show examples of realised solutions.

There are various European services in operation which can be distinguished according to the information providers, i.e.:

Public / private road authorities / operators



TIS DG03 - 01 October 2010 9/25

Broadcasters

Other Private service providers

The named channels can be differentiated between those who give collective information and those who offer individualized information. Most of the collective channels as e.g. road side displays, radio or videotext are exclusively in the responsibility of road operators, traffic information internet services can be provided by private partners, too. To offer a high-quality individualized information, (e.g. through mobile devices or navigation systems) the co-operation with private commercial partners is mandatory. Therefore a strong co-operation between EASYWAY and TISA-Traveller Information Services Association in all aspects of traffic information is highly recommended to openly discuss new requirements, creating and maintaining a market focus and ensuring one consistent set of standards and information content for the future.

1.3.1. ROADSIDE GUIDANCE SYSTEMS

Roadside guidance systems are installed on the motorways and will be operated by the road authorities or the private motorway companies. The systems consist of VMS or dynamic signage with predefined content. The systems display directional information, diversion information but also information about the traffic conditions incl. travel-time, warnings and weather conditions. Due to the installation on the road the service is usable only on-trip.

Figure 1: VMS on the A10 near Madrid in Spain

Figure 2: VMS on the A3 near Frankfurt am Main in Hessen (Germany)



TIS DG03 - 01 October 2010 10/25

1.3.2. INTERNET PORTALS

Internet portals will be operated by road authorities, private motorway companies or service providers (e.g. public or private broadcasters). The information which they provide is about warnings, weather conditions or traffic conditions. Due to the necessary equipment (Internet access) the service is mainly used as pre-trip service. In general the service is common but some services provide personalised information. The language of the service depends on the provider but can easily be provided language independent.

The information on Internet portals will be shown on maps, as text or as images from roadside CCTVs.

Figure 3: Website "bayerninfo.de": predictive and real-time traffic situation in Bavaria, with integrated road works- and weather information

Figure 4: Website "www.trafficengland.com" of the Highways Agency

1.3.3. NAVIGATION SYSTEMS

Navigation systems provide routing information to the chosen destination. The system uses static or dynamic information to reach the destination. The dynamic information can be provided via RDS-TMC or TPEG. With the provided dynamic information a flexible routing is possible and takes into account the current traffic condition, routing information and warnings. The service can be given to the driver via voice announcements, graphical display or a combination of both. The information can only be used on-trip and is language independent.



TIS DG03 - 01 October 2010 11/25

1.3.4. MOBILE DEVICES

Information which can be called with mobile phones by the drivers / travellers will be provided by radio broadcasters or private service providers. The coverage of the different services is Europe-wide. Due to the determination of the geographical position via the mobile device the information can be provided personalised but also common. It can be given via Short Message Service, voice announcements or wap-enabled services, which depends on the provider. Furthermore web-enable devices can also recall specific web-based traffic information. The information which will be provided is about the traffic condition, warnings and weather conditions. The service is used as pre-trip as well as on-trip information. Due to safety reasons the national regulations of the use of mobile phones while driving has to be taken into account.

Figure 5: Mobile device with traffic condition information service wap.sytadin.gouv.fr

Both, navigation systems as well as mobile devices have the great advantage that they can give individualized information and restrictions (e.g. vehicle-type-based speed limits).

1.3.5. RDS-TMC / TPEG / DATEX II

RDS-TMCi

RDS-TMC is a specific application of FM RDS used for broadcasting real-time traffic and weather information. Data messages are received silently and decoded by a TMC-equipped navigation system or radio and offering dynamic route guidance. The data is language independent and can be used as pre-trip or on-trip information service. RDS-TMC is a global standard and covers a large percentage of the TERN. Many parts of the TERN have no RDS-TMC coverage, however this could be provided at any time by commercial entities without market intervention by the State, or by the State if considered appropriate. The referencing based on the country-specific location code lists for the strategic European road network.

TPEGii

TPEG is a standardised world-wide technology which delivers all types of traffic and travel information content by different channels, e.g. digital Radio (DAB), Internet. It is language independent and can be used as on-trip or pre-trip information. The TPEG applications use a common location referencing method for all devices presenting text or icons on a map display.

DATEX IIiii

DATEX was developed for information exchange between traffic management centres, traffic information centres and service providers. The standard is language independent and will be used by different partners all over Europe. The second generation of the DATEX specification can also be



TIS DG03 - 01 October 2010 12/25

used by all actors in the traffic and travel information sector. DATEX II is intended to become a multi-part technical specification, maintained by CEN.

1.3.6. RADIO

Common radio broadcasters or special traffic radio broadcasters (e. g. 107,7 FM in France) are available all over Europe. They give traffic condition information, warning information and weather information to the drivers. This information is common and not personalised to the specific drivers, but can be tailored to a specific area or region. The character and the mass of information depend on each broadcaster. The information is in general not language independent and is normally an on-trip service but can also be used as pre-trip service. Broadcasters can be public or private bodies.

Figure 6: Traffic radio in France

Figure 7: Traffic radio in Dublin, Ireland

1.3.7. VIDEOTEXT

Videotext will be provided in parallel to the TV programme. The broadcasting stations provide relevant traffic information (e.g. traffic conditions, warnings, regional traffic information of conurbations). The use of videotext is only a pre-trip service and usually not language independent.

Figure 8: Traffic information via videotext of the German broadcaster WDR

1.3.8. TELEVISION

Some broadcasters in Europe provide special services on TV concerning the publication of traffic conditions. Particularly during the morning peak hours or in the case of poor weather conditions, large events or significant travel disruption. This service is not language independent and only a pre-trip service. The service on TV will be shown on maps, as texts, or on CCTV live streams.

2. Technical Issues 2.1. European Dimension

Improved information in terms of contents, quality, efficiency and comprehensibility contributes to EasyWayiv objectives in terms of mobility and safety.

Provision of information by means of pictograms or colours on a digital map tends to be language independent, but the pictograms and colours are not uniform at present. Complementary information (spoken or text) requires translation and provision in different languages.

This service directly enables the cross-border traveller to make informed decisions. It is likely that this service would have an appeal to those making long unfamiliar journeys and provides them with improved information in a predominantly language independent format.

2.2. Functional and Information Architecture

For the TIS services a uniform functional and information architecture is defined, which is shown in the Summary Document (DG01) of the Guidelines for Traveller Information Core European Services but a sub-guideline description of the functional and information architecture is described below.

Figure 10: Diagram of the information flow

The collection of data is carried out by different systems and by different partners, private as well as public bodies. Historic data can also be required to generate traffic situation predictions. All data must be based on a consistent and geographic reference model. The geographical basis should be left to the operator to define. On content platforms data from different sources is merged and aggregated. The provision to the driver / traveller is carried out by road authorities, private motorway companies, private service providers or broadcasters via different information carriers. These depend on the different application case / European country. When providing a customer oriented



TIS DG03 - 01 October 2010 15/25

traffic condition information service the users' benefit can be increased by providing a warning and general traffic information, which can be collected and verified by private or public bodies.

Within Europe different methodologies are available to aggregate the real-time and predictive traffic condition information. These methodologies are not covered by the present guideline. Content of this guideline is only data issue which will be supplied to content providers (private or public) by the data provider.

The EC funded project E-FRAMEv (following project of the FRAME project) studies ITS architecture in Europe and is a platform to provide advice and guidance for knowledge exchange and standardisation actions in the field of system architectures (more information can be found on project website).

2.3. Required ICT Infrastructure

The required ICT infrastructure for the traveller information core European services is described within the Summary Document (DG01) of the Guidelines for Traveller Information Core European Services due to the fact that the items data collection, data fusion and processing and data quality are generally the same for all sub-guidelines.

All items concerning data collection for reliable and accuracy traffic condition information are deployed and governed by the ICT Expert and Study Group. It is recommended that data collection processes / systems should ensure the following is possible:

Point measurements (e. g. loops, radar)

Trajectory measurements (e. g. ANPR)

Floating Car Data systems

The methodologies and calculation algorithms for the data fusion and processing for a traffic condition model will not be covered by this deployment guideline. They depend amongst others on the data collection system. The main data which are needed for the calculation of the traffic condition are traffic volume, speed and the road features.

The provision of the information to the driver / traveller (on trip) has to be done via end user terminals or roadside guidance systems. In-car systems (end user terminals) offer the advantage that they can inform about vehicle-type based speed limits or other vehicle-type based restrictions (see Guideline for speed limit information DG05). A few available channels are named in the chapter 1.3 (State of the art).

2.4. Standard and Agreements: Existing and Required

The standards and agreements for the traveller information core European services are described within the Summary Document (DG01) of the Guidelines for Traveller Information Core European Services due to the fact that these items are in generally the same for all sub-guidelines. Also the liability and control of information to external parties is an important issue which should be taken into account. Due to the different standards and regulations in the European countries a uniform agreement for Europe is currently not available. An overview of information services is also part of the EU-funded eMOTIONvi project. The overall aim of the project is to define and validate the framework conditions of real-time information to road and public transport users, dynamic routing services and additional travel-related services.



TIS DG03 - 01 October 2010 16/25

2.5. Need for Additional Specifications

For the sub-guideline about traffic conditions no additional specifications are currently needed.



TIS DG03 - 01 October 2010 17/25

3. Service Provision 3.1. Service Level Definition

Accurate, reliable, high-quality traffic data is a prerequisite for implementing high-quality traffic information services achieving good user response and gaining considerable benefits in traffic throughput, safety, environment and economic efficiency.

The QUANTIS project, supported by EC Directorate-General for Energy and Transport, is developing a methodology to evaluate and optimise data and service levels in terms of quality and costs in order to foster cross border data exchange and service provision according to European policy objectives. This methodology is therefore advised to be used in terms of data quality.

More information can be found on website of QUANTISvii.

Nevertheless the tables below display general criteria for Level of Service (Table 1) and Level of Quality (Table 2). It should be noted that there is no hierarchy between these criteria.

The Levels of Service (LoS) definition of Traffic Condition Information services follows the general Levels of Service definition of TIS services (see DG01). It is based on core criteria defined in DG01: User Interface, Neighbouring Provision, Local and Secondary Network Information, Level of Detail (Location reference).

TIS DG03 - 01 October 2010 18/25

The Table 3: General Criteria for Levels of Quality reflects the requirements of the data quality which are needed for the traffic conditions information. Due to the different systems and specifications all over Europe the table currently mentions no concrete figures. This table is not end-user oriented as the Table 2: General Criteria for Levels of Service. The definitions of the below-mentioned table are according to the ISO/PDTR 21707viii standard.

TIS DG03 - 01 October 2010 19/25

It is recommended that users of these guidelines endeavour to implement traveller information which advance the levels of data and levels of service levels for those criteria shown in Tables 2 and 3.

3.2. Conditions for the deployment of the Service: Operating environment

The operating environments mean a simple categorisation of roads that can be simply utilised and should be easily understood. The quality and properties of a European service vary according to the properties of the operating environment. The following table shows, in which operating environment (according to the document Operating Environments for EasyWay Services Version 1.01 22 December 2009) the service Traffic Conditions Information (Predictive and Real Time) is recommended to be provided.

3.3. Interaction with other Services

The core service of traffic conditions must interact with the other core services of the Expert and Study Group TIS as well as to actions of the other Expert and Studies Groups and initiatives of EasyWay. Furthermore the issues of the ITS Action plan has to be taken into account. A detailed description of the interaction with other services is described in the DG01 Summary Document of the Guidelines for Traveller Information Core European Services.

The most relevant interactions and strong relationships with other services regarding this guideline are:

EasyWay ESG 1 Europe Wide Traveller Information Continuity and Co-modality

o Guideline DG02 Event Information

o Guideline DG05 Travel Time Information

o Guideline DG07 Co-modal Travel information

EasyWay ESG 2 Traffic Management

o Core Service 1 Management of Sensitive Road Segments

o Core Service 3 Incident Management

EasyWay ESG 4 Connected ICT Infrastructure

EasyWay ESG 5 DATEX II

Further relationships existing to the following other expert and study groups:

EasyWay ESG 3 Freight & Logistics Services

o Core Service 2 Strategic Traffic management on corridors and networks

3.4. Conditions for Service Provision Business Mo del

Due to the different organisational structures and responsibilities in European countries about traveller information and the fact that not only one core service is normally provided by an organisation the chapter conditions for service provision will be described in more detail in the dg& Summary Document of the Guidelines for Traveller Information Core European Services.



TIS DG03 - 01 October 2010 21/25

4. Implementation Plan: Timetable, Activities and R esource Need The chapter implementation plan will cover statements regarding the topics

the vision for the future,

overview of foreseen developments,

implementation organisation for EasyWay,

activities and timetable, and

timetable and resource need.

This chapter will not be described in the individual sub-guideline but in the Summary Document (DG01) of the Guidelines for Traveller Information Core European Services in more detail.

Nevertheless future developments will be done in terms of traffic conditions information services. The data collection as well as the information provision will be more influenced by providing data from car-to-car (C2C) and car-to-infrastructure (C2I) implementations. First pilots are in progress in different countries and regions within Europe. One example for a future development is the German project simTDix. It is a research project shaping tomorrows safe and intelligent mobility through researching and testing car-to-X communication and its applications. The project started in September 2008 and will run for four years. simTD will put the results of previous research projects into practice. For this purpose realistic traffic scenarios will be addressed in a large-scale test field infrastructure around the Hessian city of Frankfurt am Main. Numerous automotive and telecommunication companies, the Hessian state government and renowned universities and research institutions have partnered up. The Federal Ministry for Economics and Technology, the Ministry for Education and Research as well as the Ministry for Transport, Building and Urban Affairs are funding and supporting the project.

The findings of this and other pilots will in due course influence the development of this Deployment Guideline and Predictive and Real Time Traffic Condition Information in general across Europe.

5. Appendix 1: State of the Art

The following examples are an overview from a lot of projects / implementations available from all over Europe. They represent the different media channels of the provision of traffic conditions information to the end-user. These examples do not represent an exhaustive state of the art all over Europe. They are provided by Easyway Partners, in order to show examples of realised solutions.

5.1. Traffic Conditions Website autobahn.NRW x

The German Federal Land North Rhine-Westphalia has implemented a website in co-operation with the University of Duisburg-Essen which provides the current traffic situation and forecasts. The website is visited by more than 100,000 users each day and on days with special weather conditions by up to 300,000 users.

Figure 11: Website "www.autobahn.nrw.de" of the road authority of North Rhine-Westphalia

The simulation algorithm OLSIM (Online Simulation) was developed in order to reproduce the current situation and to forecast the future for the whole motorway network of North Rhine-Westphalia. OLSIM is based on a cellular automaton modal for freeway traffic and needs for its operation online and historical data. The model is a quite simple approach and therefore very robust and reliable. The website provides forecasts for 30 min, 60 min, and long-term prognosis as well as information about the current situation. More information is available on the website www.autobahn.nrw.de.

This website provides amongst others a high level of quality in terms of coverage, forecast horizon, and availability.

5.2. Traffic Radio in England xi

Traffic Radio is a regionalised England-wide traffic information service and covers the motorways, trunk road network and Londons main road network. It was launched in July 2007. The service is available 24 hours a day, and every day of the year. The Information will be provided direct from the Highways Agencys National Traffic Centre and the Transport for Londons Traffic Control Centres.



TIS DG03 - 01 October 2010 23/25

Traffic bulletins are updated every ten minutes at peak hours and every 20 minutes at other times. The radio service can be listen via DAB Digital Radio, computer, or on compatible mobile devices.

Traffic Radio provides

o National traffic headlines

o Regional traffic information, depending on where you are in the country

o Road works information

o Infomercials (for example explaining the Highways Agency Traffic Officer service, safety advice and tips about planning your journey)

The radio service was developed by the Highways Agency and is working together with Transport for London. The service will be produced from a wide range of sources which provides reliable and accurate information.

The provision of accurate and reliable information from different sources means Traffic Radio provides a high level service in terms of quality.

More information is available on the website www.trafficradio.org.uk

5.3. VMS with traffic conditions information on the Munich motorway ring xii

On the accessing motorways to middle ring road of Munich VMS were installed to show the traffic condition on the ring road. The information helps the driver to find the fastest and easiest way to the destination via the rind road. The signs were installed in 2003. The red colour indicates congestions and the red-black segments indicate stop-and-go traffic.

More information is available via the MOBINET information office (www.mobinet.de)

The VMS provides a high level of quality in terms of timeliness and availability.

5.4. Audiotex in France xiii



TIS DG03 - 01 October 2010 24/25

French Ministry provides a 24/7 free phone service about the road and motorway conditions throughout France. Audiotex is part of the Bison Fut service. The key objective is to provide as many drivers as possible information in real-time. The provided information consist of roadworks, accidents, events, weather conditions, congestions, disruptions and diversions which is coming amongst others from the Gendarmerie, the Police, the road infrastructure, and the private motorway companies. Beside the phone service the website www.bison-fute.equipement.gouv.fr is in operation which provides further traffic related information for France.

Figure 14: Logo of the website and phone service Bison Fut

The information is checked, analysed and then passed on to the Bison Fut network, comprising the national centre for traffic information and seven regional traffic co-ordination and information centres covered all France.

The availability and reliability of this phone service leads to a high level of quality.
