traffic safety work is a goal common to all public authorities, police agencies and organizations in bavaria. reducing the number of traffic fatalities in a sustainable manner and continuing to lower the number of traffic accidents and road traffic injuries is a task for society as a whole. the various measures being implemented in bavaria during the road safety campaign “bayern mobil – sicher ...

Dynamic traffic management (DTM) measures are potentially powerful measures to not only improve network efficiency, but also to reduce externalities of traffic (e.g. emissions of substances, noise and safety). In current practice the deployment of DTM measures (or DTM-strategies) focuses on improving efficiency on a local level. Further the assessment of DTM is concerned with a number of predef...

Currently used traffic control measures, such as traffic signals, variable speed limits, ramp metering installations etc., are often not designed to influence the route choice of drivers. However, traffic control measures do influence the travel times that are experienced in the network. Since route choice is, at least for a part, based on experienced travel times, the control measures thus als...

Centralitymeasures, or at least popular interpretations of thesemeasures,make implicit assumptions about the manner in which traffic flows through a network. For example, some measures count only geodesic paths, apparently assuming that whatever flows through the network only moves along the shortest possible paths. This paper lays out a typology of network flows based on two dimensions of vari...

We consider optimally coordinated freeway traffic control for networks containing bottlenecks with capacity drop and hysteresis behavior. Due to the multitude of traffic jams, and the spatial and temporal relationships between control actions and traffic behavior, this problem is not as straightforward as for local control. The order in which the measures are applied may be relevant, or it may ...

We apply measures of complexity, emergence, and self-organization to an urban traffic model for comparing a traditional traffic-light coordination method with a self-organizing method in two scenarios: cyclic boundaries and non-orientable boundaries. We show that the measures are useful to identify and characterize different dynamical phases. It becomes clear that different operation regimes ar...

A study was conducted to replicate a previous study in which air traffic control taskload measures were found to predict subjective workload better than a set of communications measures. In this study, two measures of the timing of communications were computed along with two principal components describing communication content. Five principal components were derived to describe ATC taskload. T...
