This paper describes how essential it is to carry out conformance tests even if the information exchange is standardized like in traditional RDS-TMC. Tests on current navigation devices show that there is only a basic implementation of the RDS-TMC event-code realized. Quite often, different events are merged to a single one. Most of the time, just a subset of the TMC event-message-scope is used to provide the customer with detailed traffic-information. In order to relay meaningful traffic information to navigation devices, the whole information chain has to include the full scope of variants compliant to the defined RDS-TMC standards. Otherwise even basic traffic information could be unintentionally modified by at least on part of the information chain. ASFiNAG has recognized this problem on RDS-TMC traffic information in Austria and started conformance testing of RDS-TMC capable navigation devices The RDS-TMC standard has passed the standardization at least 15 years ago [1]. It could be expected that the OEMs of navigation devices should live up to the complete standards, but they don't. The success of for future ITS systems regarding traffic information will rely on the possibility to support customers with unaltered information as gathered in traffic control. Source

The national Austrian motorway operator Asfinag is considering to install temporary shoulder lane usage on a motorway as already done in the Netherlands, Germany and the UK. This paper presents the methodology and results of a recent cost-benefit study for a two-lane motorway including two interchanges and two exits/entrances. The cost of reinforcement of shoulders, widening ramps, setting up emergency refugee areas, extending the existing dynamic speed control system and installing a surveillance system is being compared with the benefit of improving the service level and its impact on safety. The benefit is justified by decreasing travel times, improving traffic flow reliability and reducing traffic emissions. Numerical analysis of microscopic traffic flow simulation indicate that the cost of temporary shoulder running can be justified if current volumes will increase by 5% to 25% during peak periods. Forecasts on the safety impact rely on observed data at German motorways with marginal decrease of accident rates due to speed harmonization as speeds will be reduced from 130 km/h to 100 km/h. The shoulder lane use has to be extended through interchanges as congestion will build up. Otherwise only the origin of bottlenecks will move. While these figures are site dependent, the general approach and methodology is transferrable. Source

One of the key aspects in the field of Cooperative Systems - at least from the point of view of a motorway operator - is the availability of reliable, cost-effective communication media to get your services and traffic messages "I2V", from the Infrastructure to the Vehicle. ASFINAG, the Austrian motorway operator, together with "Hitradio Ö3", Austria's largest radio station and ORS, the Austrian Broadcasting Service provider, therefore tested DVB-T2 as a (broadcast) carrier medium for multimedia enhanced cooperative services and traffic messages. These tests were based on previous work on Cooperative Systems, namely the system architecture and TPEG services of the "COOPERS" project, which were enhanced by adding multimedia information (camera pictures and spoken audio messages) to the individual TPEG traffic service messages. The target area for the tests was the Vienna region with the high-traffic triangle of the A23, A4 and S1 motorways. Test results showed that in spite of strong DVB-T2 coverage and signal strength, message reception beyond a speed of 25km/h was not possible with currently available DVB-T2 receiver technology. DVB-T2 in its present state therefore is not a suitable broadcast medium for Cooperative Services, although this could change when more advanced receivers are commercially available. Source

Traveller Information Services are coming up across the different regions and modes of transport in Europe. But the vision of the "Connected Traveller" could not be met yet. Real Time Traveller Information Services are providing co-modal services only in prototype applications, rarely connecting regions and are not diversified for the different users yet. This paper will give a state of the art analysis of R&D activities and current implementations in the field of traveller information services from a motorway operator perspective and will show the migration path towards co-modal and co-operative services for the traveller of tomorrow. Particular focus will be drawn on the strategic approach, goals and the derived measures by the example of ASFINAG, the Austrian Motorway and Expressway Company. The current telematics services portfolio are presented with the emphasis on cooperation models for operators in the role of content as well as service providers in the field of traffic and traveller information for customers.

Due to the constantly increasing traffic loads and the revised design approaches it becomes necessary to reassess the expected service life of existing bridges. In many cases the calculative shear resistance turns out to be particularly problematic. In the course of the revision of the Austrian Assessment Technical Regulation ONR 24008 "Evaluation of load capacity of existing railway and highway bridges" comparative calculations according to the shear carrying capacity of existing bridges conforming to Eurocode 2 and fib Model Code 2010 were carried out. The present paper summarizes the main results of the comparison between the fib Model Code 2010 and Eurocode 2 and explains characteristics of the calculations of the shear resistance according to fib Model Code 2010.
