Basic  principle of the traffic-flow control is based on minimization of total queue lengths in a micro-region [6, 4].  Measurement of the queue lengths is difficult, so it is necessary to estimate them. The traffic micro-region  can be described by a linear state space model (SSM) [6] where state is just formed by queue lengths.  The SSM includes some unknown parameters which need to be estimated together with the states. Such  the estimation requires the use of non-linear estimation techniques [2, 5, 1, 3].  The traffic model is based on traffic flow conservation principle: the queue at time k is equal to the  sum of the previous queue at time k − 1 and the arrived cars, given by the intensity and the sample  period, minus the number of cars which pass through the intersection.  The number of cars depends on the existence of queue. </abstract> <abstract language="cze" primary="0">Inteligentní dopravní řízení je dobrou možností jak zvýšit kapacitu dopravní sítě. Základní princip dopravního řízení je založen na minimalizaci celkové délky kolon v mikroregionu. Délku kolony nelze změřit přímo, ale musí se odhadovat vhodnou filtrační metodou. Z tohoto důvodu byl navržen dopravní model. V dopravním modelu se pracuje se dvěma stavy - když kolona existuje a když ne. Jako přepínač těchto dvou stavů byla použita Kroneckerova funkce, což je pro odhad nevýhodné. V této práci jsou navrženy a popsány nové tři přístupy k danému problému.</abstract>  <action target="EUR"> <ARLID>cav_un_auth*0234562</ARLID> <name>3rd International Workshop on Data - Algorithms - Decision Making</name>  <place>Liblice</place> <dates>9.12.2007-11.12.2007</dates>  <country>CZ</country> </action>   <reportyear>2008</reportyear>  <RIV>BC</RIV>      <permalink>http://hdl.handle.net/11104/0152835</permalink>       <arlyear>2007</arlyear>       <unknown tag="mrcbU63"> cav_un_epca*0092539 3rd International Workshop on Data - Algorithms - Decision Making 43 43 3rd International Workshop on Data - Algorithms - Decision Making Praha ÚTIA 2007 </unknown> <unknown tag="mrcbU67"> Janžura Martin 340 </unknown> <unknown tag="mrcbU67"> Ivánek Jiří 340 </unknown> </cas_special> </bibitem>
