Neutron production and thermal moderation at the PSI UCN source

We report on gold foil activation measurements performed along a vertical channel along the tank of the ultracold neutron source at the Paul Scherrer Institute. The activities obtained at various distances from the spallation target are in very good agreement with MCNPX simulations which take into account the detailed description of the source as built.

How Disruptive Can Shared Mobility Be? A Scenario-Based Evaluation of Shared Mobility Systems Implemented at Large Scale

This paper reports on ongoing work on getting a deeper insight into possible integrations of different shared vehicle systems. It introduces an original methodology in three stages, which helps dealing with the complexity of the problem. Using a simulation tool, different scenarios are assessed. The paper presents preliminary results obtained by simulating two extreme-case scenarios with large-scale car-sharing and bike-sharing schemes. The results suggest that shared mobility, if supplied at large scale and in the right mix, could indeed serve a large share of current travel demand without substantial losses in terms of generalized costs.

A MATSim 2015 scenario for Basel, Switzerland

The city of Basel has become a test field innovative mobility solutions in the past years. Using paid on-street parking, a free-floating car-sharing scheme (the first one in Switzerland), Uber and a potential railway line underneath the city centre, the transport network is supposed to become more efficient and, hence ready for the future. Yet, for most novel policy measures and mobility services, their respective use and impact is still unclear. To study them, disaggregated transport models such as agent-based microsimulation framework MATSim are required. While several methodologies to create MATSim scenarios already exist, only few are documented in detail. Also, Basel presents a special case, because it is located at an international border, with its agglomeration stretching into three countries (Germany, France and Switzerland). Hence, the model for the Basel region had to be generated based on a fused data set. This paper presents the data sources and methods used to set up the MATSim scenario for Basel for the year 2015. It is meant to be both a documentation for users of the scenario and a guideline for the creation of other MATSim scenarios in the context of scarce or heterogeneous data sources.

Analyse und Modellierung des Mobility-Pilotprojekts zu free-floating Car-Sharing

Im August 2014 hat Mobility in Basel ein Pilotprojekt zu free-floating Car-Sharing unter dem Namen Catch a Car lanciert. In einer wissenschaftlichen Begleitstudie wurden die Auswirkungen von free-floating Carsharing auf das Verkehrssystem untersucht. Die Ergebnisse erlauben einen Einblick in die Kundengruppen, Nutzungsarten und verkehrlichen Wirkungen von Catch a Car.
