In the following an analysis and optimization of public transport networks by object oriented logistical approach will be presented. Mathematical model of the public road transport network is derived from the graph theory. The objects in the examined transport system are the followings: characteristic points, relation system and distances of the road network; route parameters in relation with the road network; vehicle parameters; passenger-based parameters in relation with vehicle stops. The applied simulation tool is the SIMUL8 Professional, which is Windows based software. This software enables modeling mostly discrete processes and such systems (networks) which are built by discrete elements. The aim of the examinations was to minimize the above mentioned differences therefore the determination of periodical time can be economically efficient and it will also guarantee competitive travel times with private transport in the examined relation. New optimization procedure was worked out during the examinations with the elaborate computer simulation model which is applicable to make connection between the network sections operated on different kinds of timetables in a proper way from the view of operator as well as the customers. Using the optimal periodical time the average waiting time increases by approximately 20 %, while the number of customers rises by 40 % and the cost increases proportionately with the number of customers on the bus connection points in the examined area. Examining further problems related to the periodic timetable elaborate procedures will be applicable in the future; e.g. the efficiency of the road and railway public transport systems can be comparable.
