The linkage between climate change and energy consumption of hungary in the road transportation sector
The aim of this article is to prove the connection between CO2Â emission and climate change, and to estimate the CO2Â emission of the transport sector in Hungary. We have to clarify the emission of the transport sector in order to get information on externalities, which is a further step toward a sustainable society. The sustainable development is a development, where the pace of technical development, the satiation of increasing supply and the raw materials and resources of Earth are poised so that the rate of living and opportunities of the next generations need not be worse. One of the most emphasized goals of the transport policy of the European Union is sustainable mobility. For this reason transportation systems must be developed and standardized, the effectiveness of transportation services must be increased, while the environmental pollution must be decreased or prevented. Decoupling motorization from environmental pollution is the task for engineers. Decoupling the increase of economical activity from mobility is the task for economists.

Linear optimization model of urban areas’ operating efficiency
The efficiency of urban transportation is getting more and more important because of the increasing rate of mobility demand. To plan, control and organize urban transportation in the most efficient way, we also need to consider the aspects of land use. To handle both of the mentioned urban planning areas together, we shall develop models, which are able to pay attention to all of their restrictive factors in the most simple way. It is a possible solution to simulate the urban area through a linear programming model.

Introducing decisive development orientations into transport modelling
To effectuate a consistent methodology for urban planning taking into consideration the viewpoints of land use and transportation, we need to approach the subject and consider complex social and economical aspects. To handle both of the above mentioned urban planning areas, we shall develop models able to pay attention to all of their restrictive factors within temporal properties.

Proposal for Reduction of Calibration Process in Reference to Trip Distribution Method
The nowadays applied different macro models or parts ofthose, which describe the urban environment, can originate in afour-step modelling process. The paper focuses on the trip distributionprocess (the 2"d step) because of its significant calibrationrequirements. Therefore, it is possible to make the entiremodelling process more reliable (dependent upon the reliabilityof the available databases )
Implementing ETC System on Hungarian Motorway Network
Question of transport infrastructure charges - among others- covers calculation and allocation of infrastructure costsreferring different users. Cost allocation forms the basis of settingthe user charges. The reason for the existence of applyingmileage-proportional pricing system is generally accepted, asthe European regulations also discuss this topic seriously. Thismileage-proportional pricing system demands an appropriatetoll collecting system, which meets the requirements of arrangedprinciples. Among these, the most important principlesare equity, effectiveness and efficiency. Electronic Toll Collecting(ETC) systems are an appropriate solution to solvingcharging problems in various ways according to the differentkind of systems. In Hungary the current motorway charging systemis not an adequate solution for success of these principlesin the long-term. A new, mileage-proportional pricing system isbeing initiated. This study presents the plans of HungarianETC system for motorway network, focusing on introductoryissues. Among several preparatory steps, examining acceptabilitybarriers of ETC system for the stakeholders of transport isneeded. Their problem perception is to satisfy their- often contrary-demands in equal, fair and effective ways. The policy implementationprocess also plays an important role to generatesufficient conditions to implement this solution. This contributionis to discuss these objectives in applying the ETC system inan acceptable way
