Abstract
Assessment of the effects of increased heavy vehicle traffic growth on the Austrian infrastructure in alpine regions
Within this study the accelerated damage of flexible road pavements due to the rapid increase of heavy vehicle transit traffic under particular harsh climatic conditions in alpine regions is investigated. Research objectives are (i) estimation of the development of heavy vehicle traffic volume in alpine regions for different traffic types, i.e., transit or local traffic, on the basis of weigh in motion measurements of vehicles and derivation of reliable axle load spectra for different truck types, (ii) drawing of an thermal energy balance of flexible pavement structures based on meteorological parameters in alpine regions, giving access to thermal dilation/shrinkage strains and to the actual rheological behavior of asphalt, which strongly depends on the temperature, (iii) the formulation of a micromechanical model to better explain material fatigue due to traffic loading as in consequence of micro crack initiation in bituminous materials, (iv) comprehensive fatigue testing on hot mix asphalt types typically used in alpine regions in order to both, quantify effects of temperature, load amplitudes and load pause, as well as to validate the formulated micromechanical model. Therefore recommendations can be drawn for optimized asphalt mix and pavement structure design in alpine regions. The applications for this research project as well as its financial support were approved by the Austrian Academy of Science in April 2004 for the duration of two years.

Abstract
Emission Controlled Traffic through the Alps - Law of Plants and Ecology in Traffic
The main goals of the project are to compile an innovative emission limitation model for the traffic sector and to develop a premium calculation system based on the emission trading system to secure the ecological capacity, especially in ecological sensitive areas (e.g. alpine landscapes). To develop a technical, economical, ecological and legal safeguarded model the cooperation of an interdisciplinary team consisting of traffic researchers, traffic ecologists, traffic economists and legal experts was chosen. The milestones of the project are the examination of the legal framework and the analysis of an emission trading system being the essential part of a process control instrument complying with the law of plants. The connection of an approach based on the installation-related law with the basic deliberations of the emission trading system within the traffic sector should be established on those milestones.
The project team aims to develop an operational decision support for an ecologically oriented transport policy using a fundamental novel approach in legal and ecological means. Furthermore, those theoretical achievements shall be validated on their practicability in a pilot study.
