    Development, Implementation (Pilot) and Evaluation of a Demand-Responsive Transport System

    Get PDF
    This paper presents the partial results of the first phases of the BOOLEAN (BĂŒrgerorientierte Optimierung der LeistungsfĂ€higkeit, Effizienz und AttraktivitĂ€t im Nahverkehr) research project. The demand-responsive transport and operating systems as well as virtual vehicle concepts are developed in a “real-world laboratory” in Schorndorf. The demand-responsive transport system is implemented as a part of the existing public transport system and will be tested for nine months. The paper focuses on the derivation of system requirements for the operating system and vehicle concepts. The virtual vehicle concepts developed within the project are specifically designed according to the needs of demand-responsive transport systems and are based on automation technologies and electric propulsion. An inter- and transdisciplinary approach integrates perspectives from the social, technical and computer sciences and various local stakeholders (operators, municipality, politics and citizens of a medium sized town in Southern Germany). Transformative processes are induced, supported and scrutinized during and beyond the pilot phase

    Investigating Behaviour and Population Dynamics of Striped Marlin (Kajikia audax) from the Southwest Pacific Ocean with Satellite Tags

    Behaviour and distribution of striped marlin within the southwest Pacific Ocean were investigated using electronic tagging data collected from 2005–2008. A continuous-time correlated random-walk Kalman filter was used to integrate double-tagging data exhibiting variable error structures into movement trajectories composed of regular time-steps. This state-space trajectory integration approach improved longitude and latitude error distributions by 38.5 km and 22.2 km respectively. Using these trajectories as inputs, a behavioural classification model was developed to infer when, and where, ‘transiting’ and ‘area-restricted’ (ARB) pseudo-behavioural states occurred. ARB tended to occur at shallower depths (108±49 m) than did transiting behaviours (127±57 m). A 16 day post-release period of diminished ARB activity suggests that patterns of behaviour were affected by the capture and/or tagging events, implying that tagged animals may exhibit atypical behaviour upon release. The striped marlin in this study dove deeper and spent greater time at ≄200 m depth than those in the central and eastern Pacific Ocean. As marlin reached tropical latitudes (20–21°S) they consistently reversed directions, increased swimming speed and shifted to transiting behaviour. Reversals in the tropics also coincided with increases in swimming depth, including increased time ≄250 m. Our research provides enhanced understanding of the behavioural ecology of striped marlin. This has implications for the effectiveness of spatially explicit population models and we demonstrate the need to consider geographic variation when standardizing CPUE by depth, and provide data to inform natural and recreational fishing mortality parameters

    Evaluation of the HadGEM3-A simulations in view of detection and attribution of human influence on extreme events in Europe

    A detailed analysis is carried out to assess the HadGEM3-A global atmospheric model skill in simulating extreme temperatures, precipitation and storm surges in Europe in the view of their attribution to human influence. The analysis is performed based on an ensemble of 15 atmospheric simulations forced with observed Sea Surface Temperature of the 54 year period 1960-2013. These simulations, together with dual simulations without human influence in the forcing, are intended to be used in weather and climate event attribution. The analysis investigates the main processes leading to extreme events, including atmospheric circulation patterns, their links with temperature extremes, land-atmosphere and troposphere-stratosphere interactions. It also compares observed and simulated variability, trends and generalized extreme value theory parameters for temperature and precipitation. One of the most striking findings is the ability of the model to capture North Atlantic atmospheric weather regimes as obtained from a cluster analysis of sea level pressure fields. The model also reproduces the main observed weather patterns responsible for temperature and precipitation extreme events. However, biases are found in many physical processes. Slightly excessive drying may be the cause of an overestimated summer interannual variability and too intense heat waves, especially in central/northern Europe. However, this does not seem to hinder proper simulation of summer temperature trends. Cold extremes appear well simulated, as well as the underlying blocking frequency and stratosphere-troposphere interactions. Extreme precipitation amounts are overestimated and too variable. The atmospheric conditions leading to storm surges were also examined in the Baltics region. There, simulated weather conditions appear not to be leading to strong enough storm surges, but winds were found in very good agreement with reanalyses. The performance in reproducing atmospheric weather patterns indicates that biases mainly originate from local and regional physical processes. This makes local bias adjustment meaningful for climate change attribution

    Raus aus dem Elfenbeinturm: BĂŒrgerbeteiligung in Verkehrsprojekten am Beispiel des Reallabor Schorndorfs

    Die aktive Beteiligung von BĂŒrger/innen und weiteren lokalen Akteuren besitzt großes Potential fĂŒr eine nachhaltige Stadt- und Verkehrsplanung zur Erreichung von Klimazielen. Doch wie kann eine BĂŒrgerbeteiligung umgesetzt werden, die ĂŒber reine Informationsveranstaltungen hinausgeht? Im Projekt Reallabor Schorndorf wird ein dialogorientiertes, kooperative Beteiligungsformat erprobt, mit dessen Hilfe ein an die BedĂŒrfnis der zukĂŒnftigen Nutzer orientiertes ÖPNV-Konzept entwickelt werden soll

    The German Aerospace Center (DLR), the University Esslingen, the University Stuttgart, the Verkehrs- und Tarifverbund Stuttgart (VVS), Knauss Linienbusse, Daimler AG and the City of Schorndorf have been engaged in a project (“Reallabor Schorndorf – Reality Lab Schorndorf”) to develop an innovative, demand-oriented operational system as well as a vehicle concept for public busses in the city of Schorndorf in Baden-WĂŒrttemberg. A crucial aspect of the project is the integration and participation of users of Schorndorf’s transport system into the development process against a transdisciplinary background

    Observations of mesoscale movements in the short-tailed stingray, Dasyatis brevicaudata from New Zealand using a novel PSAT tag attachment method

    Short-tailed stingrays (Dasyatis brevicaudata) are the largest stingrays in the world. They are common in New Zealand waters and aggregate seasonally in large numbers at the Poor Knights Islands Marine Reserve (PKMR), where they are a major attraction. Pop-up satellite archival tags (PSAT) were attached to two female short-tailed stingrays at two New Zealand offshore islands (within and nearby the PKMR) to investigate patterns of movement. These are the first PSAT data published for a stingray species. The rays were tagged for 62 and 151 days using a novel method of tag attachment developed specifically for ray species. Analyses of geolocation, depth and behavioural data indicate neither ray moved large distances (≀ 25 km) from the tagging locations. However, they showed a seasonal shift to deeper waters, progressively increasing time spent at greater depths and decreasing time spent at shallow depths towards winter. In addition, one ray displayed strong diel vertical movements. The method developed for PSAT attachment to stingrays proved successful and can be applied for long-term (> 6 months) movement and behavioural studies
