Linear optimization model of urban areas’ operating efficiency

Abstract 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

Abstract 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.

Future trends in road transport systems in Hungary and in the EU

Efficient transport is a key ingredient in the competitiveness of an economy. Intra-EU passenger transport has grown more than the population – which means a greater mobility (more kilometres travelled) per person – but less than GDP. The road transport systems affect practically all the environmental elements, and they have a role in every harmful effect the environmental protection is dealing with. At the same time, the degree of the environment pollution and the role of the road transport within total pollution are significantly different. The impacts on nature conservation caused by road transport infrastructure and operation are of greater importance. Beyond direct land use, the separation of the habitats, the separation effect of the highly trafficked lines greatly influence the biodiversity, the survival of the valuable groups of the flora and fauna. From landscaping aspect the increased construction, the implementation of industrial sites experienced along the expressways and also expected along the planned sections may result to unfavourable effect indirectly, especially in the agglomeration.

Conceptual analysis of ITS effect on SCGE models

SCGE models are ideal tool for modelling socioeconomic effects in a spatial manner. The current research is investigating this modeling methodology from the view of transportation and investigating the reciprocal cooperation possibilities with ITS systems. In this combined approach the main aims are to identify the different infrastructure and ITS development possibilities and their effects to set up the base ground for the future developments and technological advantages.

Strategy Planning of Sustainable Urban Development

As the rapid growth of world population and its concentration in cities around the globe takes place, sustainable urban development has constituted a crucial element affecting the long-term outlook of humanity (Auclair, 1997). Besides, in the urbanized areas a high level of GDP (gross domestic product) concentration can be observed. That should make us care for the operational efficiency of the urban areas more and more studiously. Dynamic and continuous horizontal and vertical growth of urban areas makes the question of efficiency more and more important. Handling productivity concentration has been a key issue for economists and solving transportation problems – due to population concentration – has been just as important for engineers for a long time. Representatives of abysmally separated scientific fields tried to solve the efficiency problems of certain areas which can be characterised by lack of capacities, extreme population and productivity density.
