PHÄLIKS - The Phenomenon of driving left on multi-lane motorways - Measures and recommendations for the rule of keeping to the right side of the road
Within this study the phenomenon of driving on the left side on motorways was described and analysed with psychological, traffic related, juridical and sociological methods. Based on these results adequate measures were developed; that should enhance or facilitate the proper compliance with the traffic rules in Austria, which is driving on the right side of the road. Experts from relevant fields of expertise and competence (traffic, landscape, sociology etc.) accompanied the whole process by giving their input, evaluating the results of the exploration of the driving-left issue, and prepared and optimised the practical output of the project.
In this project products with a better toxicological profile than the preservative creosote were under examination as alternatives for the impregnation of wooden railway sleepers. The demanded key properties had to be geared to those shown by creosote: high biological efficacy, long service-life, no increase of corrosion, low conductivity of impregnated sleepers and high resistance against physical and chemical stress.
The objective of this project was the elaboration of the handling instruction for the adaptation of conventional existing bridges to integral bridges by means of a survey of the national and international literature as well as statistical examination taking essential parameters into account. In addition to the essential construction details of the integral or semi-integral bridges (e.g., frame corner and concrete hinge) the deformable slip plate will also be examined and design rules will be suggested.
RISKANT – Risk model for the analysis of accidents with stationary obstacles on highways und expressways
The objective of the RISKANT study was the development of a risk model for crashes with stationary obstacles along the road.
The project ODIMAK dealt with a new capacity analysis method for multi-level intersections based on existing guidelines. Measurements of complex weaving procedures on the ASFINAG network were taken into account. A microscopic traffic simulation tool was applied to develop an analysis method for multiple weaving segments. The traffic flow model was calibrated using the previous measurements. Typical geometrical settings were defined and modeled. The simulation results are taken for regression analysis to identify suitable dimensioning procedures, which were discussed within the FSV committee on intersections.
Safe Guarding – Potential of lateral road restraint systems on road safety capacity in the motor- and expressway network of the ASFiNAG
Run off accidents with personal injuries are the second most frequent type of accidents on the ASFiNAG road network. Road restraints are an important instrument to reduce accident severity. For that reason the efficiency of these systems was analysed, in order to insure an efficient road maintenance regarding infrastructure costs and to reduce furthermore the severity of these accidents.
FTB-Concrete Surface – Influence of air void characteristics and aftertreatment for frost and de-icing chemical resistance of concrete carriage-ways
This research project analyzed how a noncompliance with requirements or has a negative effect on the freeze-thaw resistance of concrete pavements.
INFRAplusGEO – Potenzialanalyse und Umsetzungsmöglichkeiten geothermischer Energie im Bereich der Infrastruktur der ÖBB
The aim of the project is the acquisition and compilation of the potentials and the realistic (technically, economically, environmentally, operationally) opportunities to use geothermal energy in the infrastructure of the ÖBB. Therefore, the infrastructure and geothermal potential acquired (GIS-based) and (in consultation with the ÖBB) and pilot plans for most useful and effective opportunities created.
New concretes for the infrastructure; energy and resource optimized
Combined fibre concrete – Development of a crack-free railway sleeper through the use of a combined fiber-reinforced high-strength concrete
In practice the use of pre-stressed concrete sleepers is often accompanied by cracks-occurrence, such as longitudinal, lateral and shrinkage cracks. At the occurrence of cracks the resistance of sleepers to environmental influences is reduced. By the development of a combined fibre reinforced high-strength concrete, the risk of a formation of micro- and macro cracks can be substantially reduced, whereby the expected lifetime of concrete sleepers can increasing significantly and a costly renovation can be avoided.
Shear area model - Mechanically consistent shear area-model for existing bridges without or with small lateral force reinforcement
Within the scope of this research project a mechanically consistent model for the shear resistance of bridges without or low shear reinforcement was developed.
MANEUVER - Development of avoidance measures for misconduct on railway crossings with the aid of the traffic psychology
The objective of the project was to develop cost-effective measures (education, awareness-raising, roadside infrastructure) with the help of experts and road traffic participants to reduce misdemeanour at level crossings. Traffic psychological research methods will be adopted.
OBESTO – Implementation of the user oriented and Life Cycle Costing approach in the Austrian design method for upper road structures
Within this project, performance-based material behaviour of Hot Mix Asphalt (HMA) was implemented in the Austrian design approach. Considering actual asphalt mechanic behaviour, as well as specific traffic loads and climatic conditions, the structural technical life time of road pavements with different bitumen, bitumen systems and mix design could be determined and considered in the design process. In addition, a standardized life-cycle cost analysis helped to evaluate and identify the economic differences between alternative pavement types. The results of this project should be the basis for a complete revision of the Austrian pavement design standard, RVS 03.08.63.
RELSKG - Developement of a simplified method of calculations for noise protection walls with complex geometry
The aim of the project was to determine correction factors for noise barriers with complex geometries to be used in the ray-tracing method based on numerical simulations with the boundary element method. The results of the simulations were validated by measurements. Complex geometries of the noise barriers included barriers with more than one refraction edge and curved geometry. The expected correction factors allow the implementation of the results in standard calculation software used in practice.
The objective of the project was to apply the EU regulations 2009/661/EC to Austrian conditions in order to find the actual feasible noise reduction, as well as suggestions of how to adapt the Austrian calculation basis.
The R&D service investigates the effects of Industry 4.0 on the transport and logistics sector both from a practical and a scientifically based perspective, taking special consideration of Austria’s external relationships. The investigation is intended to supply a suitable basis on which to elaborate different handling and strategy recommendations for RTI and transport policy.
The project RTM-O aimed the development of a capacity/management software for the digitally coordinated supply chain, from the handover point of the shipping customer to the acceptance point of the recipient.
The study eComTraf analysed the impacts of the relation between consumer needs, the offers of online retailers and the CEP (courier-express-parcel) service industry on the development of the overall transport system.
KoLaMBra – Development of an integrated organizational concept for a cooperative last- mile logistics branch
The project developed a "matching platform" for the logistics industry, i.e. a kind of partner exchange for the urban transport of goods.
