Transport justice has two essential dimensions: (1) compensating for inequalities in access to mobility, and (2) mitigating the disproportionately burdensome negative consequences of transport. In light of the urgently needed action regarding climate change especially in the transport sector, measures reducing carbon emissions to mitigate the impac...

MATSim is an open-source simulation framework for mesoscopic traffic simulations that has gained popularity in recent years. In this paper, we present a MATSim model for the city of Vienna, with a particular emphasis on the intermodal routing framework used to create agent trips, and the development of a utility function to specify different agents...

Shared Autonomous Electric Vehicles (SAEVs) are expected to enter the transportation market in the upcoming decades. In this paper, we describe the preparation of a MATSim model for Vienna in which we add this new service as a new transportation mode. We simulate different pricing schemes for various SAEV fleet sizes and analyze their impacts. Our...

Expectations are that automated and connected mobility will increase road safety and traffic efficiency. However, due to possible shortcomings of new technologies, road users may be confronted with disturbances and potential safety risks. The mitigation of such risks will bring necessary changes to road infrastructure, vehicles and road-user behavi...

SUMO2019:Editor's Preface This volume contains the papers presented at the SUMO Conference 2019 Simulating Connected Urban Mobility. The conference was held in Berlin from 13-15 May 2019. The goal of the conference was to present new results in the field of mobility simulation and modelling using traffic tools and data which are open available.Ther...

Changes made in urban street lighting not only influence peoples’ perception of public space but also affect mobility behavior. Even if current standards and regulations are addressed, lighting qualities vary widely depending on the technology used and the environment chosen for installation. Especially glare is a visual property that is not addres...

Road networks are complex interconnected systems. Any sudden disruption can result in debilitating impacts on human life or the economy. In particular, road systems in mountain areas are highly vulnerable, because they often do not feature redundant elements at comparable efficiency. This paper addresses the impacts of network interruptions caused...

Light Emitting Diode (LED) technology promises a great energy saving potential and is therefore increasingly used for traffic areas or urban spaces, respectively. While many LED luminaires for street lighting meet the current standards, many light experts as well as the general public judge the lightings as glaring and visually uncomfortable. This...

Wirkung von neuartigen Beleuchtungskonzepten auf das Mobilitätsverhalten von Personen: Urban Light - Akzeptanz von LED-Beleuchtungssystemen im Straßenraum

Wirkung von neuartigen Beleuchtungskonzepten auf das Mobilitätsverhalten von Personen: - Akzeptanz von LED-Beleuchtungssystemen im Straßenraum - Verhalten vor und auf Schutzwegen bei adaptiver Beleuchtung

Road safety is influenced particularly by three factors: human behavior, transport planning, and vehicle development. Electric vehicles and their interaction with non-motorized road users require new considerations in terms of road safety due to their specific characteristics like quicker acceleration and lower acoustic perceptibility due to missin...

In the presented case study, travel times for passenger cars (PC) and heavy goods vehicles (HGV) were predicted with a data-driven, hybrid approach, using historical traffic data of the entire high-ranking Austrian road network. In case flow data were available, travel time was predicted with a Kernel predictor searching for similar speed-density p...

Advanced routing and navigation incorporating real time traffic information is state of the art - at least for car drivers. The number of cyclists using digital navigation even to reach familiar destinations is increasing with the availability of waterproof smartphones and smartphone mounts. However, for realistic routing and real-time cycling assi...

A tool is presented that is capable of reading from, writing to and converting between various sources. Currently supported file formats are ROOT, HBOOK, HDF, XML, SQLITE and a few text file formats. A plugin mechanism decouples the file-format specific 'backends' from the main library. All data are internally represented as 'heterogeneous hierarch...

Elastic electron backscattering coefficients have been measured for 24 elemental solids (Ag, Al, Au, Be, Bi, C, Co, Cu, Fe, Ge, Mg, Mn, Mo, Ni, Ta, Te, Ti, Pb, Pd, Pt, Si, V, W and Zn) for energies between 50 and 3400 eV. Values for the electron inelastic mean free path (IMFP) were derived from the experimental intensities on the basis of a simple...
