FE 70.0912 / 2015 reduction potential, quality requirements and recommendations for the use of methods of dynamic environmentally sensitive traffic management on roads (short title: "Environment-sensitive traffic management") to protect human health and the environment were among others several air pollutants by Directive 2008/50 / EC on ambient air quality and cleaner air for Europe limited and transposed into national law by the 39th Federal Immission Control Ordinance (39th BImSchV). In many cities, but also at Trunk Road sections, then local measures to reduce air pollution and comply with the limits were taken. An environment-sensitive traffic management (UVM) can perform as part of an overall concept to improve the environmental performance of transport. Dynamic UVM systems engage in the traffic one only when it due to actual measurements, or predictions of simulation calculations, based on the volume of traffic and the local environmental impact, is necessary and appropriate in order to reduce ambient air pollution. With the proposed research approach will be shown how effective hitherto unrealized UVM systems are the components used in the systems used for spatial and temporal prediction of air pollutant concentrations wer¬den and how these can be possibly improved, which polls and adaptation processes of traffic management (VM ) and UVM are necessary in order to realize an effective interaction which synergies can result from a coupling of VM with UVM and to what extent can be simple solutions define without substantial losses in the applicability and effectiveness.

Despite extensive research in the field of damaging alkali-silica reaction (ASR) in the field of concrete construction at the present time is the detailed damage mechanism of AKR, in particular the complexity of AKR to concrete pavements, not sufficiently clarified scientifically. Therefore, the validity of currently coming to apply test methods may not be sufficient. For the development of a test method for fast and reliable evaluation of aggregates with regard to their behavior in an alkaline medium and thus to evaluate their resistance to an AKR should at selected aggregates with different alkali sensitivity physicochemical processes and the relationship between the structure of grains in the surface region and their solubility in an alkaline environment studied, analyzed and described. This is intended especially that knowledge and understanding are built and extended, which comprises the reaction processes on the surface of aggregates. After selecting the items to be examined aggregates (.. At least 2 chippings and at least 2 gravels) with different alkali sensitivity will gradually be working: 1. Characterization of the structural state: Spatial determining the externally accessible surface and porosity determination; qualitative and quantitative determination of the mineral phases. 2. Testing for the solubility behavior of the aggregates in an alkaline medium and calibration of these tests according to the results of WS-concrete experiments General Circular Road no. 04/2013. 3. Merge and evaluation of all test results and dissipation for safe, rapid test methods of aggregate for permanent avoidance of harmful ASR in concrete pavements.

So far, support all road safety relevant findings on the accident risk of older drivers and drivers in cross-sectional analyzes. On this basis, national and international publications document an increased distance-related accident risk of older drivers from around 75 years. So far not been explored, the individual developments mobility-related and traffic safety-related characteristics of older car drivers Female and male. Thus, the important insight into the dynamics of change processes is lacking. This also applies to the question of when age-related traffic safety-related changes occur exactly, how long does it take to be formed certain behavioral adaptations and through which internal or external factors initiated these. The aim is to pursue the development of safety-related traffic and mobility-related characteristics of seniors in the context of a longitudinal study over a period of 5 years. It should be examined what personal changes (eg diseases, medication, expectations, attitudes.) And what changes in their life circumstances (objective life situation) and the traffic environment affect when and how on mobility behavior and the risk of accidents of this target group. Here, a time period should be defined, which is probably as a transition to an increased risk of accidents. According to previous knowledge, such a transition from an age of about 70 years will take place. The interpretation of the results of this study should be geared, inter alia, to the role of mobility-related self-regulation of older motorists and drivers.

So far, the state detection of road infrastructure carried out by consuming tests at equidistant intervals. This verification is very manpower, time and cost-intensive, since the relevant infrastructure elements visually and handnah (bridges) or using complex instrumentation (pavements) must be checked. As between the individual inspections is a relatively large time interval, very little is known about the current state of the road infrastructure. Therefore, impairment, damage or fatigue are often detected late, which increases the extent of damage and the repairs will be considerably more expensive overall. Modern vehicles are equipped with numerous sensors that their operating status and to some extent also their environment can be captured. The aim of this preliminary study is to examine to what extent can be obtained continuously by means of vehicle sensor information in the future, allow conclusions on the quality and construction of road infrastructure and any changes thereto. It is the innovative approach of the preliminary study in detection, treatment and holistic view vehicle-based sensor information and the derivative infrastructure-specific attributes in real-time from circulation. Should it be possible to develop this new approach for the continuous acquisition of information about the current condition of the road infrastructure by means of data collection from the flowing traffic, implement and introduce, this would make an important contribution to increase the availability and efficiency, provide for the protection and conservation of road infrastructure , The results of the preliminary study are intended to shed light on the fundamental feasibility of such an approach and to clarify the scope of work and priorities for further research and implementation projects.
