A method of telematic transport systems identification
Kornel B. WYDRO

A ICT equipment of the transport seen as a whole field of activity is in Poland, in comparison to many other more advanced countries, relatively poor. Especially a great gap can be recognized when it concerns solutions based on complex, integrated and common principles of established architecture. It brings about many effects resulting negatively in more or less direct manner on global country economy development.

System oriented modernization and informatization of the transport is to be an urgent and valid challenge for nearest years, understanding and taking up of which will allows – beside improving of transport branch – more complete Poland’s assistance in the development of European Information Society.

The taking up of restructuring and improving activities in the transport branch needs to work out a proper manners and ways of proceedings, having in mind the fact, that surrounding or collaborating countries are much more advanced in knowledge and experience in this technological area. Of course their experience is to be utilized when building modern transport development policy comprising creation of intelligent transport systems in Poland. But proper development of the policy needs to have good recognition on the actual state of transport telematic implementations working on Polish roads.

The dominant feature of all the modern actions it this area is their ordering according to national architectures of intelligent transport, build on the basis of recognized state of applications and needs expressed by the users. For in Poland as far there is no reliable recognition of the working telematic solutions, the elaboration of the methodology of recognition in this field seems to be necessary.

A present work concerning such a problem was made in course of realisation of the task “ICT techniques in the transport” in the frames of Multi-annual Program “Development of the telecommunications and post in the information society era” realized mainly in the National Institute of Telecommunications.

Foresees further continuation of this works by collecting discussed data and it’s analysis for the regulation needs, and also continuation by undertaking efforts to create at least national communication architecture of intelligent transport (according to European ITS Architecture rules).

The data concerning existing telematic applications can be gained from its builders and users as well as from institutions that, for the reason of their obligations, should possess such a data. The data can be gathered in active direct way i.e. by the survey made with help of collection of the answered questionnaires, or indirect, by analysis of the existing information resources in this field, being possible to find in various free accessible publications, esp. in the Internet resources, as well as those, being in the disposal of various administration entities.

For the sake of very big variety of categories of applied solutions and also rich variety of functionalities in frames of particular category, fundamental difficulty makes a formulation of questionnaires in a manner assuring proper answers allowing also gathering a satisfactory knowledge about researched problem.

In these circumstances the preliminary condition for preparation of the proper questionnaire is the systematic ordering of the information searching area with regard to subjects as well as with regard to content-related scope. It will allow to adjust questions to the subject character and to gather concise answers allowing recognizing the classes of installed applications. Even future analysis of ICT implementation level in transport – especially that computer based – will be much easier.

Also for Internet exploration such an ordering will make easier to form the structure of computer assistance for Internet interviewing, t. ex. CAWI (Computer Assisted Web Interviewing) system.

A basic problem is to define the object of survey action and how to ask the addressee so as on this base get answers describing state of the working telematic applications in a satisfactory accurate manner. For this reason we propose to systemize known applications what should facilitate definition of the object area of survey and the structure of related subject’s area comprising sources of wanted information.
For the reason of big variety of known transport telematic applications it is necessary to differentiate them and ascribe into some groups. It can be done in accordance to distinguished general functions of systems and in accordance to systems structures.
Regarding their main functions systems use to be divided on various manners. For example, according MIP/TEMPO project, following categories of the systems can be accepted as a basic:
Road Monitoring Infrastructure – realizing weather and road surface monitoring, air quality monitoring, travel time data collection and other.
Traffic Centres – having the means of data exchange, sharing data with traffic and transport managements, making cross-border data exchange and so on.
Traffic Management and Control – distinguished systems of traffic management and control in transport corridors, urban and interurban areas, sections of road (e.g. tunnels, port parts and other), area-wide traffic management such as regional or inter-regional (within one Euro-regions).
Traveler Information Services – realizing access to pre-trip information for route planning and journey time estimating, to information of traffic conditions, weather conditions, even multi-modal pre-trip information. Giving access to on-trip information for navigation, diversion signs (obligatory diversion, recommended re-routing), warnings/advice for multimodal transport and other.
Freight and Fleet Management – control of the heavy goods vehicles traffic, improve safety conditions and coexistence of light and heavy vehicles on the roads, freight tracking, measures for freight inter-modality, efficiency of goods transfer, improved inter-modal information services for freight operators etc.,
Electronic Fee Collection – interoperable electronic systems for fee collection, electronic Euro-vignettes for heavy goods vehicles and other payments.
Incident and Emergency Handling – realizing automatic incident detection and location, identification, integration of automatic systems vs. systems information exchanges.

More accurate survey of systems mentioned or described in specialist literature allows identifying following structural ordering:
• Groups of system (t. ex. Fee Collection),
• Particular systems (t. ex. Electronic Fee Collection),
• Subsystems (t. ex. automatic registration plate’s recognition for vehicle category identification),
• Circuits realizing informatic elementary functions (t. ex. obtaining the electronic pictures of the registration plate).
Such a division have to be helpful for formulation of the detailed the questions in the survey questionnaires.

From the point of view of specific technical role of applied means is rational to define particular features of systems, giving possibility to help identify just a role of deployment. For instance, when speaking about applied ICT technologies identification, following division can be useful:
• Systems detecting and collecting information;
• Systems processing information;
• Systems distributing information.

In the case of telematic systems, in each of group are used t. ex. specific information transmission means and reference to above-mentioned classification can be useful when we want to recognize system as using specific transmission technology.


The sources of information can be distinguished as direct and indirect. The first category comprises various types of subjects working with the implementation, exploitation and maintenance of telematic systems and therefore administering the original information sets laying in their disposal. The second category consists of sets of journals, Internet and databases of statistical institutions. All the sources taken together can be defined as a subject area of survey, if can be assumed that all the information have their possessor (or dispatcher) or comes from such one.

The area of direct sources i.e. subject area may – in a general, but essential from the planned survey point of view – be divided into mentioned below groups:
• Managing institutions, needing telematic systems for significant transport infrastructure improvement – like road administrations, operators and other;
• Telematic equipment and systems producers, fulfilling the market needs – i.e. equipment and service suppliers, contractors, installation enterprises etc.,
• Creators of development rules in the transport telematic area – as standardization, legislation and regulations institutions,
• Direct users of telematic systems – travelers, drivers, transport enterprises and other like those.

For the needs of data collection about existing systems those last can be neglected (they cannot be neglected when it concerns a survey of user needs what usually is done for example when deploying new system or enhancement o systems existing, but especially when builds a national architecture of intelligent systems).

As indirect sources are classified those, which generates information created not directly accordingly to needs of data collection for telematic systems survey. Here are such as journals, firm pamphlets and publications on electronic form, especially related WWW sides. Yet have to be noted that information accessible in those sources are usually more or less out of the date.
For the reason of very big diversity of known telematic solutions, preparation of surveying techniques ensuring proper identification of this solutions requires careful elaboration of the method which be applied in practice for obtaining needed information. It means that first of all, after construction of telemetric solution classification, for example as upper, following works have be done:
• Creation of the necessary register of telematic solutions,
• Preparation of the questionnaires adjusted to particular types of subject – as concise as possible, but allowing to obtain sufficient data,
• Preparation of the platform for filed in questionnaires registration,
• Preparation of the software for automatic search in Internet.

The data collection system should be constructed also with consciousness that it will be possibly adopted to use in transport telematic systems development monitoring and transport user needs recognition.
