In part I of this book a dynamic migratory model connecting the microlevel of individual migration trends with the macrolevel of interregional migration is developed. Its derivation makes use of the master equation method. Applying a ranking regression analysis, the trend parameters of the model are correlated to regional socio-economic key factors. In part II the model is applied to interregional migration within the countries Federal Republic of Germany, Canada, France, Israel, Italy and Sweden. In part III a comparative analysis of the results is given. In part IV a selfcontained derivation of the master equation and of solutions relevant for the migratory system is given, the ranking regression analysis is exemplified and a computer program for the estimation of trendparameters is added.

We all know that networks are fundamental prerequisites for prosperity and production. Transportation and communication are indispensible to society, they are the elements which bind all economic systems together. Without networks and communica tion all social and economic life will be reduced to isolated phenomena. Therefore, transportation can't be assessed in the same way as other services. A smoothly functioning system of communications is also a prerequistite for social and economic integration between separate geographical regions. The modernization of the infrastructure is therefore an urgent task and a precondition for carrying out the whole of Europe's ambitious political, economic and social agenda. Since the need for communication and transportation does not know any national borders, the functioning of the networks needs to be adopted to this new economic and political geography. Congestions of cities, highways, railroads, airways and tele communications must be tackled, if precious working, commuting and leisure time is not to be wasted and heavy burdens on the environment avoided. European traffic, is for example, expected to double within the next twenty years. In certain transport modes the growth is expected to be even faster - air passenger transport doubled in 10 years and goods transport on roads doubled in 15 years."

During the seventies and eighties, the industries associated with the transportation of goods and people have been exposed to some profound changes. The quickening pace of technological change - with its growing emphasis on telecommunications, knowledge-handling capacity, and air transportation - is increasing the discrete character of the world economy. Thus the network structure of global development patterns is becoming more important, with metropolitan centres as key nodes and rapid transportation routes as key links. In this evolutionary situation, changes in the preferred mix of transport modes are inevitable. The faster and more direct modes will be favoured, individually and in combination, and there will be an increasing interest in transportation policies and the provision of infrastructure. This volume contains a collection of innovative papers presented at the First International Conference on Transportation for the Future, held in Sodertalje, Sweden in July 1988. Twenty industry leaders and prominent scientists from Europe, USA and Japan present their views about the ongoing transformation of production and distribution systems among firms striving for Just-In-Time methods, economies of scope, and a fully integrated approach to their economic activities. The future of passenger travel and infrastructure are also discussed. The resulting book presents a surprisingly consistent picture of how the transportation industries of the industrialized nations may be expected to grow and change in a long-term perspective."

The focus of this book is to present the latest aspects in the area of human behavior and its relation to planning of an optimal traffic safety. The contributions from authors in various disciplines such as scientists, medical practitioners, administrators and practitioners from the car industry examine how road-user behavior can cause accidents and how decision-makers from various sectors of society may influence road users' behavior. The development of modern vehicles and new traffic systems requires more sophisticated behavior and technology. New medical technologies such as improved neuropsychologic methods and descriptive mapping of behavior with imaging techniques facilitate the understanding of the anatomy and physiology of human behavior. The increased knowledge of normal and pathologic behavior contributes to strenghten primary prevention with the goal of reducing traffic accidents.
