In this paper, we present the ROADSAFE toolkit which has been designed to support efficient user-centered development and on-the road evaluation of the human-machine interface of safety services. The toolkit includes features for the investigation of future in-car applications, such as real-time multimedia supplements on different quality levels, interactive scenarios requiring user input, and deployment on arbitrary end devices. The developed toolkit has been validated within the ROADSAFE project, a scientific cooperation between FTW, ASFINAG, Kapsch TrafficCom, Fluidtime, and TU Vienna, to improve vehicular communication systems.

This paper presents results of a stakeholder analysis which was performed by the EasyWay Cooperative Systems Task Force. The study focuses on the road operator which is one of the stakeholder groups relevant for the deployment and operation of cooperative systems. The road operator will not only be affected by the impacts of cooperative systems but may also play an active part in the operation of cooperative services. Optional function schemes of selected cooperative services are described and related potential roles of the road operator in the operation process of these services are identified. Results of a deepened analysis of the developed function schemes and role profiles are shown which give insight in expectations and aspirations towards cooperative services from a road operator's view.

In this paper we demonstrate the potential of using anonymized cellular network signaling data to extract and analyse macro-mobility patterns. We show that, by properly processing signaling data passively collected from a cellular core network, our approach is able to catch crucial characteristics of wide-area mobility patterns. By means of simple illustrative examples, we present an analysis of country-wide travel relations, the dynamics of travel times between cities, and commute behaviour.

How can targeting co-operative I2V services to the so called climate-conscious urban mobility avant-garde contribute to broadening the co-operative systems user base? Service idea is to support drivers in their practice of greener decision making in those cases where they feel they need to ride a car. By driving individualization of cooperative services to the extreme, current feasibility limits for road operators and TCCs are sounded-out. At the same time the enhanced deployment potential is unveiled when piggy-packing context-specific service ideas onto mainstream cooperative services. Ultimately all convenience and service quality ambition comes down to a kind of co-operative services-enabled climate alarm-clock. The idea is to reduce mobility-related distress peak levels-typically from traffic jams and from challenging weather conditions. The service bundle also includes real-time co-modal routing recommendations on more efficient start times for specific journeys as well as alternative routing. This all may soon become available on Smartphone apps optimized for car drivers in urban traffic contexts. Reducing distress fosters feedback-enhanced learning and helps to better cope with severe weather situations. More generally speaking we investigate how the I2V co-operative services concept can be used for communication to pioneering climate-conscious citizens and therefore better prepare the next generation-opinion leaders.

IABSE Conference, Nara 2015: Elegance in Structures - Report | Year: 2015

A new roadway transition structure for long integral abutment bridges has been invented at the Institute of Structural Engineering at Vienna University of Technology. It consists of prefabricated prismatic concrete elements which are positioned on a sliding plane and connected by flexible corrosion resistant tension members. At one end, these tension members are comiected to the bridge structure and at the other end to an abutment block. The total horizontal displacement of the bridge is evenly distributed among small joints between the elements. As part of the extension of the A5 highway in Austria, a 112 meter long integral abutment bridge has been designed. It was decided to incorporate the new flexible expansion joint in this bridge project, in order to gain experience with the design, the installation and the durability of this new type of transition structure.

Roadway expansion joints for bridges are highly dynamically loaded structural elements due to their position. Expansion joints are renewable structural components according to Eurocode 0 and should therefore be designed for a service life of ten to 25 and more years. Regardless of the design life there is a need to minimize effort of conservation of such expansion joints. The research project "Development of wear-resistant expansion joints for bridges" (EVAF) therefore has the objective on the basis of a comprehensive damage surveys, literature studies and numerical stress analysis to determine the causes of early damage patterns and to develop innovative solutions to reduce the maintenance effort and further to avoid the damage with respect to the individual types of expansion joints for bridges. Thereby robust, low-maintenance, with low cost serviced expansion joints for bridges should be developed. This paper shows the outcomes of the first two work packages from the surveys and numerical analyzes which have been carried out due to the intense interaction between the customer bmvit, ASFINAG and ÖBB as well as the industrial partner Mageba and the research partners AIT (Austrian Institute of Technology) and University of Natural Resources and Life Sciences Vienna within the research initiative vif2012. © 2014 Ernst & Sohn Verlag für Architektur und technische Wissenschaften GmbH & Co.

The construction of autobahns and dual-carriageway roads is only possible with considerable use of resources and visible encroachment in the environment and landscape. The ASFINAG is aware of their responsibility for this, so modern and resource-saving construction materials and methods are being used for the new building of federal roads. This also includes the intention to balance masses on the overall project and the best quality management of tunnel spoil. A good collaboration of technical design and environmental design with clarification of the potential for material recycling and the necessary approvals are preconditions for sustainable materials management. Nevertheless, the implementation of major projects like the S 10 Mühlviertler Schnellstraße (S 10) is faced with challenging conditions, which complicate efficient and sustainable handling of materials. © 2014 Ernst & Sohn Verlag für Architektur und technische Wissenschaften GmbH & Co.

Motivated by the fact that a significant number of personal mobile devices are carried into vehicles and that the majority of those devices continuously emit Wi-Fi frames, we investigate the feasibility to use these transmissions for road traffic analysis. Background transmissions are emitted by the majority of Wi-Fi-enabled devices by means of so called probe requests. We show by a real-world measurement on an Austrian motorway that a sufficient number of probe requests can be received in order to re-identify devices traveling between two locations and to estimate travel times. Our results show that by proper post-processing of measurement data, meaningful travel time information for the respective highway segment can be derived. We also propose a simple method to protect user privacy by pruning the recorded Wi-Fi device identifiers. Doing so allows us to generate travel time estimates without creating reversible relations between measurement data points and individual devices, which could potentially be linked to user identities. Obviously, using truncated identifiers has an impact on the estimation result. Based on the measurement data at hand we can show that there exists a fundamental trade-off between privacy and accuracy. © 2014 IEEE.

Proceedings - Rapid Excavation and Tunneling Conference | Year: 2011

In the autumn of 2009, the construction works were initiated for the approx. 5.5 km long 2nd tube of the Bosruck road tunnel on the A9 Pyhrn motorway in Austria. In the course of the more than 100-year history of tunnelling at the Bosruck, this tunnel is the fourth tunnel that is being constructed in this part of the central mountain range of the Eastern European Alps. The 1st tube of the Bosruck road tunnel was constructed between 1980 and 1983. Soon after start-up, substantial damage became apparent in the 1st tube of the road tunnel. It was only possible to maintain operation by means of continuous and costly rehabilitation measures. In 2005 the extent of damage finally led to the decision to add a second tube to the road tunnel and to carry out a general rehabilitation of the existing tube of the road tunnel. The major conclusions drawn from the damages that occurred in the first tube of the road tunnel were used for the erection of the 2nd tube and will be discussed in the present paper. For this new tunnel tube, it has been decided to use a stiff lining concept (i.e., resistance principle) to counteract swelling and creeping pressures. Back analyses have been carried out to determine heave deformations observed in the first tubes.

Austria and Switzerland successfully implemented the first technical interoperability between 2 countries in 2004. Following this, a second interoperable service was launched on 1st of September 2011. This new service between Austria and Germany named TOLL2GO is the first toll collection service that is based on both microwave and satellite technology. With this unique service in Europe it was proven that a GPS-based tolling system can be connected to a DSRC system. TOLL2GO gives drivers of heavy good vehicles with 12 tons or more the possibility to only use one OBU (Toll Collect OBU) for paying tolls in both countries. Hereby it is important to mention, that besides one OBU for use in both countries, it is necessary for the customer to have 2 contracts (one with the German toll operator and one with the Austrian one). With this so called 2-contract (technical) interoperability, the invoicing remains completely separate. Currently ASFINAG is working on the next step, namely the implementation of a one-contract (contractual) interoperability solution for heavy goods vehicles together with the Scandinavian Consortium EasyGo. This presentation gives a brief overview about the challenges during these interoperability projects and the lessons learned especially with regard to introducing EETS (European Electronic Toll Service).
