In the part one o f this p aper deals w ith including an architecture o f Intelligent T ransportation S ystem s (ITSs) in G lobal A rchitecture o f the N ational Inform ation System (G A N IS) o f the C zech R epublic (CR).
The pap er is based on G lobal A rchitecture o f Inform ation System (G A IS) concept.
T he G A IS concept is, in fact, general considered a stable fram ew ork a rational creation o f inform ation system s (IS) private firm s and the state authorities and organisations.

The architecture reflects several different view s o f th e exam ined system and can be d ivided into:
• R eference arch itectu re - defines the m ain term inators o f ITS system (the reference architecture yields to definition o f boundary betw een ITS system and environm ent o f ITS system ).
• F u n ctio n a l arch itectu re - defines the structure and h ierarchy o f ITS functions (the functional arc hitecture yields to the definition o f functionality o f w hole ITS system ).
• In form ation arch itectu re - defines inform ation links betw een functions and term inators (the goal o f inform ation architecture is to provide the cohesion betw een different functions).
• P h ysica l a rchitecture - defines the physical subsystem s and m odules (the physical architecture could be ad o p ted according to the user requirem ents, e.g. legislative rules, organisation structure, etc.).
• C om m unication arch itectu re - defines the telecom m unication links betw een physical devices (correctly selected com m unication architecture optim ises telecom m unication tools).
• O rganisation arch itectu re - specifies com petencies o f single m an agem ent levels (correctly selected organ isatio n architecture optim ises m anagem ent and com petencies at all m an agem ent levels).
The ITS architecture o f th e C zech R epublic is conform able w ith the K A REN m ethodology, w ith A C T IF results and p artly w ith C O M E T A recom m endations. T he main afford is p u t into the pro m o tio n o f ITS architecture in real ITS practise and using it for solving the different ITS o ptim isation tasks.
7. P R O C E S S A N A L Y SIS O F ITS SY STEM S
T he instrum ent for creating ITS architecture is the process analysis show n on Fig.4. The processes are defined by chaining system com ponents through the inform ation links. The system com ponent carries the im plicit system function (F I, F2, F3, G l , G 2, G 3, etc.). The te rm inator (e.g. driver, consignee, em ergency vehicle) is often the in itiator an d also the term in ato r o f th e selected p rocess.
In c lu d in g o f IT S S in th e n a tio n a l in fo rm a tio n sy s te m a rc h ite c tu re o f th e C z e c h R e p u b lic 437
The chains o f functions (processes) are m ap p ed on physical subsystem s o r modules (first process is defined w ith help o f functions F I, F2 and F3 on Fig.4, second process is defined b y chaining the functions G l, G2 and G3) and the inform ation flow s between functions th at specify the com m unication links betw een subsystem s o r m odules. If the time, perform ance, etc. constrains are assigned to different functions and inform ation links, the result o f the presented analysis is the table o f different, often contradictory, system requirem ents assigned to each physical subsystem (m odule) and physical com m unication link betw een subsystem s.
From the poin t o f view the construction o f the selected subsystem it is possible to consider a single universal subsystem fulfilling the m ost exacting system param eters, the creation o f several subsystem classes according to a set o f system param eters, creation o f a m o d u lar subsystem w here the addition o f another m odule entails th e increase o f system param eters, etc.
The sam e p rinciple m ay be applied w hile designing the telecom m unication environm ent betw een selected subsystem s (unified radio b an d frequency for all transport telematic applications, com bination o f individual transm ission system s, com bination o f fixed and radio netw orks, etc.). In analogy w ith the subsystem design, the design o f the telecom m unication environm ent m ay b e divided into several classes or, as the case m ay be, the transm ission environm ent m ay be designed in a m odular w ay w hen h igher system param eters on the inform ation transm ission m ay be achieved by adding additional m odules.
S im ilar situation applies to the other part o f ITS system , or betw een ITS systems o f different transport m odes, e.g. road and railw ay transport. It is necessary to consider whether each transport m ode has to have the selected subsystem alone available o r w hether there is an opportunity for sharing such subsystem s, etc.

The p ap e r is outlined the G A N IS in five-level hierarchy o f m anaging and inform ation system s o f the top executive, national and regional p u blic adm inistration in the CR, with effect from 1 Jan u ary 2003. G lobal architecture o f hierarchical inform ation system o f transport C R (G A H IS C T ) is outlined and shortly described.
T he ITS s and/or th e ITS architecture are declared like an explicit integral part o f the G A H ISC T . The hierarchical inform ation system o f tran sp o rt o f the C R is one o f explicit part o f th e N ational In form ation System (N IS or ISP A ) o f the C zech R epublic. It m eans that the ITS s and/or the C zech ITS architecture are an im plicit inseparable p art o f the N ational Inform ation S ystem o f th e CR.
B asic objective o f th e creation o f th e n ational (C zech) ITS architecture is the achievem ent o f th e interoperability b etw een in dividual telem atic applications, including m axim um u se o f available infrastructure b y all te lem atic applications w hile keeping system requirem ents in individual te lem atic applications (technical requirem ents: safety, reliability, availability, integrity, etc.; transport related requirem ents: transport com fort, m inim isation o f external req uirem ents o f the transport rela ted process, m aintaining transport po licy objectives at national and E uropean level, etc.).
The result o f the ITS architecture should be a design o f individual subsystem s and functional blocks, including the definition o f th eir system param eters for O BU (On-Board U nit), teleco m m u n icatio n environm ent and p rocessing centres for all kinds o f transport telem atic applications.
