Episode Notes Currently there are over 22 million Asians across the US representing a range of ethnic groups originating in East Asia, Southeast Asia, and the Indian subcontinent. Yet, oftentimes, the ways we think of Asian American history is tethered to the East and West Coasts. But Asians in America have a long history in the Deep South, a history that has garnered growing attention. Documentaries like “Far East, Deep South” and “Blurring the Color Line: Chinese in the Segregated South” follow the filmmakers as they explore their personal family histories. How does knowing these histories help us have a fuller and richer understanding not only of Asian Americans but also the South? And how might these histories be shaping our shared present and future? Today I sit down with Dr. Shaolu Yu, whose work examines these questions and more.   Dr. Shaolu Yu is an Associate Professor of Urban Studies and the Chair of Asian Studies at Rhodes College. Trained as an urban geographer in an interdisciplinary background and participating in projects in urban studies in China, the U.S., and Canada, she has developed a comparative and global perspective and a mixed method approach in her research on cities.

Researching Transit
RT12 - Dr Taru Jain - The role of car share in the mobility ecosystem

Researching Transit

Car share is a subscription service for cars. It allows users to drive a car, without owning a car. The city of Melbourne, Australia, plays host to over 1,500 shared vehicles which operate as part of commercial fleets or peer-to-peer (privately owned) vehicles. But the benefits of car share go beyond those to the individual (flexibility and cost savings from registration, fuel and the capital cost of cars). At a societal level, car share also benefits cities by reducing parking demand and congestion. But what is the role of car share in the transport system? How does it serve the mobility needs of its users and provide an alternative to car ownership? Taru’s research aimed to help different levels of Government in Victoria understand how car share was affecting mobility choices and thus its role in supporting the State’s transport and sustainability objectives. “Public transport is great, but not having a car on weekends when you want to travel different places can be frustrating, and that’s what the role of car share was.” To gain this understanding, Taru’s project pursued three objectives: exploring trends in usage and availability of care share, understanding car share impacts on travel behaviour; and gaining an understanding of the psycho-social motives and barriers for care share use. Interviews of car share users also revealed five types of users. Importantly, two of the user groups – the car aspirers and car sellers – were characterised by changes in their car usage and ownership over the course of their car share membership. Taru emphasises the importance of major life events – a detail that often goes overlooked in purely quantitative studies. By limiting unnecessary trips, and limiting the acquisition of new cars, car share also contributes to a more efficient transport network. Taru’s research also identified an important role for Local Government in maximising uptake, retention of car share subscribers and stemming car ownership. Dr Jain emphasises the need for clear regulation and supportive policies so that operators can ensure widespread availability of car share vehicles, emphasising the importance of providing car share proximity to public transport. In doing so, governments will help maximise retention of car share subscribers and stem car ownership. Her work suggests that rather than being seen as a silver bullet to private car related problems, car share should be seen as part of a mobility ecosystem which encourages sustainable travel practices. This research has introduced Dr Jain to some useful frameworks for understanding behavioural motivations and enablers, which she explains with reference to the developing Corona virus pandemic and the behavioural responses seen in its midst.

Thème 3 : Le vélo. Episode 1 : Le vélo : ça roule sans piste ? Erigée en petite reine du déconfinement, la bicyclette se voit soudainement mise sur le devant de la scène. De nouvelles pistes cyclables temporaires sont tracées en une nuit, ouvrant la voie aux nouveaux cyclistes, qui, les collectivités l’espèrent, pourraient conserver durablement cette pratique. En effet, la recherche est unanime : les pistes cyclables sont une condition clé au développement de la pratique du vélo. Elles permettent à une variété d’usagers de se sentir en sécurité, améliorent l’efficacité du vélo et la qualité de son expérience d’usage en ville. Si les infrastructures cyclables sont un facteur clé, et feront d’ailleurs l’objet d’un épisode dédié de Lost in Transportation, il serait néanmoins trompeur de résumer la pratique du vélo à ces seules voies réservées. Des questions bien plus générales conditionnent cette pratique : pour qui le vélo est-il attractif ? Dans quels contextes ? Avec quelles activités est-il compatible ? Comment la « culture vélo » varie-t-elle d’un pays à l’autre ? Bref, comment la pratique du vélo s’insère-t-elle dans la vie quotidienne ? Le lien entre vélos et modes de vie, pour une variété d’usagers et dans une variété de contextes, est discuté dans cet épisode qui a pour objectif de complexifier le discours autour des pistes cyclables.

Sven Müller ist Professor für Verkehrsbetriebswirtschaft im Studiengang Verkehrssystemmanagement an der HTW hier in Karlsruhe. Im Rahmen seiner Promotion an der TU Dresden in der Gruppe von Knut Haase begann er der Frage nachzugehen, welche Faktoren die Verkehrsmittelwahl für den Schulweg beeinflussen. Hintergrund dieser Frage war, dass zu der Zeit in Dresden die Schließung von Schulstandorten heiß diskutiert wurde. Die Notwendigkeit von Schulschließungen war dabei nicht umstritten, jedoch welche konkrete Variante die für alle beste Lösung darstellen würde. Hier war die Diskussion emotional stark aufgeladen, d.h. ein Modell, das bei der Planung des Schulnetzes für objektive Informationen sorgt, wäre ganz besonders hilfreich. Am besten mit klaren Empfehlungen für optimale Lösungen in Bezug auf Schulwege und deren Kosten. Der naheliegende und auch herkömmliche Indikator für so ein Modell ist eine Distanzminimierung. Dadurch lassen sich objektive Aussagen zu minimalen Transportkosten für die Schüler ermitteln. Jedoch stellte sich schnell heraus, dass verlässliche Aussagen dazu fehlten, welche Verkehrsmittel die Schüler anteilig wählen und wieso. Ebenso welche Schulen die Schüler selbst wählen würden und wieso. Deshalb war ein wichtiger Ausgangspunkt für das Forschungsthema eine sehr groß angelegte Schüler-Befragung, die von den Studierenden im Rahmen eines Seminares geplant und durchgeführt wurde. Durch das große Engagement war die Stichprobe schließlich sehr groß. Es wurden dabei Fragebögen in fast allen Schulen verteilt und die Ergebnisse in einer selbst konzipierten Datenbank gesammelt - gut aufbereitet für eine anschließende Auswertung und Optimierung. So war es möglich, aus diesen Daten Prognosen zur Verkehrsmittelwahl in Abhängigkeit von Distanz und Verkehrsmitteloptionen zu erstellen und über verschiedene Schließungsszenarien eine optimale Verteilung der Schulen (in Bezug auf Kosten für die Stadt) zu ermitteln. All das floß auch in die Promotion von Sven Müller ein. Als wichtiges Problem für die mathematische Behandlung der Optimierung erwies sich, dass die Optimierungslösung auf die Daten zurückwirkt. Das führt auf ein dynamisches Problem, das mit herkömmlichen Methoden nicht behandelt werden kann. Auch bei der ÖPNV-Planung von optimierten Liniennetzen tritt das Problem auf: Kürzere Reisezeiten und mehr Direktverbindungen führen z.B. zu einem höheren Fahrgastaufkommen. Mathematisch ausgedrückt heißt das die Nebenbedingungen werden dynamisch und das Problem wird in der Regel nichtlinear. Betriebliche Problemstellungen haben oft ein ähnliches Problem, d.h. die Daten bleiben nicht fix sondern sind abhängig von der gefundenen Lösung. Ein wichtiges Teilergebnis des Forschungsvorhabens von Sven Müller ist eine exakte lineare Reformulierung für das ursprünglich nicht-lineare Optimierungsmodell. Ein weiteres grundsätzliches Problem ist, dass die Nutzenfunktion hinreichend genau beobachtet werden müsste. Ideal wäre es, wenn nur noch weißes Rauschen im Störterm berücksichtigt werden muss, d.h. alle zufälligen Anteile sind wirklich nur zufällig und unverbunden mit den beobachteten Daten. Das ist in der Realität leider nicht möglich und so führen nicht beobachtete Anteile zu Kovarianzen im Modell, die nicht null sind. Anders ausgedrückt, ist der stochastische Anteil nicht nur weißes Rauschen. Nebenbei gewann er noch einige andere Erkenntnisse. Z.B. ist es für die Prognose der Fahrradnutzung nicht ausreichend, die Distanz als Maß zu nehmen, da es bergauf- bzw. bergab gehen kann und das für die Entscheidung mindestens ebenso wichtig ist wie die Entfernung. Dieser Frage geht er zur Zeit auch mit seinen Studierenden im Studiengang Verkehrssystemmanagement an der HTW nach. Zwei weitere Themen, an denen Sven Müller zur Zeit arbeitet, weil sich gute Anknüpfungspunkte aus den eben geschilderten neuen Optimierungsstrategien bieten, sind z.B. die Versorgungsplanung in der Medizin und die Planung der Pilgerströme in Mekka.Genauer gesagt geht es bei der Versorgungsplanung um Vorsorgeprogramme (Prävention). Durch eine hohe Attraktivität des Angebots soll erreicht werden, das möglichst viele Patienten freiwillig teilnehmen. Auch hier ist die gute Erreichbarkeit der Ärzte wichtig, aber auch ihre Attraktivität. Es gilt abzuwägen, wie viele Ärzte an dem Präventionsprogramm mit welcher Kapazität teilnehmen sollen. Einerseits aus Kostengründen natürlich möglichst wenige. Aber andererseits ist gerade die kurze Wartezeit auf einen Termin ein Garant dafür, dass der Termin auch wahrgenommen wird. Somit führt die Optimierung wieder auf ein dynamisches Problem. Viele Standorte führen zu kurzen Wegen und weniger "no shows". Aber viele Untersuchungen bei einem Arzt stärken seine Kompetenz - verlängern aber die zu erwartende Wartezeit. Leider führt das außerdem auf ein nicht konvexes Optimierungsproblem, d.h. die Existenz von Optima folgt nicht mit traditionellen Methoden (bei denen ist Konvexität eine zentrale Voraussetzung). In Mekka sind während einer reicht kurzen Zeit etwa 2-5 Millionen Pilger unterwegs, um Rituale durchzuführen wie die Umkreisung der Kaaba und die symbolische Steinigung des Teufels an drei Säulen. Um das Risiko von Zwischenfällen, bei denen in der Vergangenheit schon hunderte von Todesopfern zu beklagen waren, zu senken, wird das Verhalten der Pilger modelliert in Bezug auf Geschwindigkeit und Dichte. Anschließend werden rund 2 Millionen Pilger, Routen zugewiesen, die so berechnet sind, dass alle Routen möglichst kreuzungsfrei sind. Weiterhin erhalten die Pilger fest zugewiesene Steinigungszeiten, so dass die erwarteten Dichten möglichst unkritisch sind. Der Einfluss von bestimmten Fehlern, wie z.B. falsch gesetzte Zäune oder falsch interpretierte Anweisungen kann dabei nicht völlig ausgeschlossen werden und wird als Risikofaktor in der Auslastung der Routen berücksichtigt. Die Studierenden im Studiengang Verkehrssystemmanagement an der Hochschule Karlsruhe - Wirtschaft und Technik sind hier an forderster Forschungsfront dabei. Z.B. mit Experimenten zu Fußgänger-Verhalten. Denn auch hier ist eine gute Datenlage der Schlüssel zum Erfolg. Literatur und weiterführende Informationen S.

Dr. Rodrigue's research interests mainly cover the fields of transportation and economics as they relate to logistics and global freight distribution. Specific topics over which he has published extensively cover maritime transport systems and logistics, global supply chains and production networks, gateways and transport corridors. He has authored five books, 25 book chapters, more than 40 peer reviewed papers, numerous reports, and delivered more than 135 conferences and seminar presentations, mostly at the international level. Dr. Rodrigue developed a widely used online reference source about transportation which became a textbook, The Geography of Transport Systems, with its third edition published in June 2013. He is also on the international editorial board of the Journal of Transport Geography and the Cahiers Scientifiques du Transport, acts as the Van Horne Researcher in Transportation and Logistics (University of Calgary). He is a member of the PortEconomics.eu initiative regrouping the world’s leading maritime transport academics and performs advisory and consulting assignments for international organizations and corporations. Dr. Rodrigue is a member of the World Economic Forum’s Global Agenda Council on Advanced Manufacturing (2011-2013). In 2013, the US Secretary of Transportation appointed Dr. Rodrigue to sit on the Advisory Board of the US Merchant Marine Academy. The container, like any technical innovation, has a functional (within transport chains) and geographical diffusion potential where a phase of maturity is eventually reached. Evidence from the global container port system suggests five main successive waves of containerization with a shift of the momentum from advanced economies to developing economies, but also within specific regions. These waves are illustrative of major macroeconomic, technological and sometimes political shifts within the global economy. Containerization has therefore a cyclic behavior and that inflection points are eventually reached, marking the end of the diffusion of containerization in a specific port or port range. Future expectations about the growth of containerization thus need to be assessed within an economic cycle perspective instead of the rather linear perspectives.

The Urban Context of Logistics and Freight Distribution’ (2008, with Ashgate Publishers, Aldershot/UK) and the forthcoming ‘Cities, Regions and Flows’ (2012, co-edited with Peter V.

Markus Hesse’s research is concerned with principles of urban and regional development (particularly patterns of urbanisation and sub-urbanisation), European urban development and policy, and the significance of global flows and mobilities for cities and regions. Developments and conflicts in Luxembourg and the Greater Region are subject of his research as well.
