PrevisÃo de Demanda por GÃs Natural Veicular: Uma Modelagem Baseada em Dados de PreferÃncia Declarada e Revelada / DEMAND FORECAST FOR NATURAL GAS VEHICLES: A MODELLING BASED ON STATED AND REVEALED PREFERENCE.Josà Expedito BrandÃo Filho 04 February 2005 (has links)
AgÃncia Nacional do PetrÃleo / A utilizaÃÃo de modelos de escolha discreta à um mÃtodo eficaz que retrata o comportamento dos consumidores em diversos mercados. Sua aplicaÃÃo tem sido amplamente difundida na literatura para retratar a realidade de mercados de produtos e serviÃos no setor de transportes. Quando sÃo necessÃrios estudos de previsÃo de demanda, o modo mais adequado consiste na utilizaÃÃo conjunta de dados de preferÃncia declarada (PD) e preferÃncia revelada (PR). A combinaÃÃo destes dados fornece modelos estatisticamente mais consistentes do que aqueles estimados com dados puros de PD ou de PR. Dessa forma, o presente trabalho aplica uma metodologia baseada em modelos de escolha discreta com insumo de dados de PD e PR, chamada de GNVPREV, para analisar as preferÃncias dos usuÃrios de combustÃveis, enfocando o gÃs natural veicular - GNV, dentro de um contexto competitivo de um mercado de energÃticos veiculares. Esta anÃlise foi restrita aos usuÃrios de veÃculos leves - automÃveis, camionetas e caminhonetes - que utilizam a gasolina, o Ãlcool ou o prÃprio GNV. A metodologia GNVPREV foi aplicada para uma Ãrea de estudo constituÃda por uma parte do distrito sede do municÃpio de Caucaia, situado na RegiÃo Metropolitana de Fortaleza, Estado do CearÃ. O levantamento de dados a partir de questionÃrios de preferÃncia declarada e revelada, elaborados previamente, forneceu insumos para estimativas de funÃÃes de utilidade e obtenÃÃo de parÃmetros de elasticidade de demanda, trade-off entre alternativas e cenÃrios de previsÃo de demanda. Os resultados obtidos foram satisfatÃrios, dentro das limitaÃÃes dos dados primÃrios e secundÃrios, e confirmaram um melhor desempenho do modelo quando estimado com dados conjuntos de PD e PR.

Issues in Urban Travel Demand Modelling : ICT Implications and Trip timing choiceBörjesson, Maria January 2006 (has links)
Travel demand forecasting is essential for many decisions, such as infrastructure investments and policy measures. Traditionally travel demand modelling has considered trip frequency, mode, destination and route choice. This thesis considers two other choice dimensions, hypothesised to have implications for travel demand forecasting. The first part investigates how the increased possibilities to overcome space that ICT (information and communication technology) provides, can be integrated in travel demand forecasting models. We find that possibilities of modelling substitution effects are limited, irrespective of data source and modelling approach. Telecommuting explains, however, a very small part of variation in work trip frequency. It is therefore not urgent to include effects from telecommuting in travel demand forecasting. The results indicate that telecommuting is a privilege for certain groups of employees, and we therefore expect that negative attitudes from management, job suitability and lack of equipment are important obstacles. We find also that company benefits can be obtained from telecommuting. No evidences that telecommuting gives rise to urban sprawl is, however, found. Hence, there is ground for promoting telecommuting from a societal, individual and company perspective. The second part develops a departure time choice model in a mixed logit framework. This model explains how travellers trade-off travel time, travel time variability, monetary and scheduling costs, when choosing departure time. We explicitly account for correlation in unobserved heterogeneity over repeated SP choices, which was fundamental for accurate estimation of the substitution pattern. Temporal constraints at destination are found to mainly restrict late arrival. Constraints at origin mainly restrict early departure. Sensitivity to travel time uncertainty depends on trip type and intended arrival time. Given appropriate input data and a calibrated dynamic assignment model, the model can be applied to forecast peak-spreading effects in congested networks. Combined stated preference (SP) and revealed preference (RP) data is used, which has provided an opportunity to compare observed and stated behaviour. Such analysis has previously not been carried out and indicates that there are systematic differences in RP and SP data. / QC 20100825

Le système régional d'innovation : le cas de la région Provence-Alpes-Côte d'AzurRoillet, Jonathan 16 November 2011 (has links)
L’objectif de cette thèse est d’établir par le biais d’outils économiques une meilleure représentativité d’un domaine de pointe spécifique à l’échelle d’un territoire, à savoir l’innovation. Ce travail de recherche s’inscrit comme un élément de réponse à une interrogation du Conseil Régional de Provence-Alpes-Côte d’Azur à propos de la détermination du « potentiel innovant » régional. Cette institution est à l’origine de ce sujet de recherche.Dans une première partie nous cherchons à comprendre et à analyser le lien entre innovation et territoire. Pour cela nous procédons dans un premier temps à l’identification des soubassements théoriques, et ce à travers une revue de littérature et une analyse interrogative autour de cette articulation innovation/territoire (chapitre 1). Une fois le caractère systémique de l’innovation mis en évidence, notre démarche nous conduit dans un second temps à développer une approche territoriale de l’innovation pour approfondir notre sujet (chapitre 2). Cette approche trouve pleinement son sens dans un troisième et dernier temps où nous appliquons à ce lien innovation/territoire le concept de « système régional d’innovation » (chapitre 3).La seconde partie de la thèse cherche à comprendre les « rouages » de l’innovation sur le territoire régional de Provence-Alpes-Côte d’Azur. Cette approche s’effectue à partir du cadre conceptuel développé précédemment et que nous considérons ici comme le plus pertinent, à savoir le système régional d’innovation. Tout d’abord nous élaborons un aperçu du territoire régional, notamment en utilisant le regard que les instances décisionnelles ont sur lui en matière d’innovation (chapitre 4). Cela nous permet de voir quel est le système régional d’innovation propre à Provence-Alpes-Côte d’Azur. De ce fait nous pouvons développer une analyse de ce système identifié, et cela à travers une lecture en trois temps du schéma de l’innovation régionale.Dans un premier temps nous identifions les éléments qui composent le cœur du système régional d’innovation (chapitre 5). Ces éléments n’ont jamais fait l’objet à notre connaissance d’un recensement complet au sein d’une typologie argumentée tel que nous le réalisons ici. Certes il s’agit là d’un travail à la fois dense et complexe qui se traduit par une très forte dimension descriptive. Toutefois ce travail nous est apparu nécessaire pour répondre à l’attente exprimée dans l’introduction quant à l’identification et l’analyse du « potentiel innovant » de la région Provence-Alpes-Côte d’Azur.Dans un second temps nous nous penchons sur les acteurs qui « gravitent » autour du cœur du système régional d’innovation et interagissent avec et à travers lui (chapitre 6). Nous cherchons à comprendre les moyens dont ils disposent pour innover. Cette analyse a recours à un certain nombre d’indicateurs et d’enquêtes. Elle se prolonge par la mise en perspective de la vision globale apparue via l’utilisation d’un indicateur composite.Après avoir identifié le cœur du système régional d’innovation et les acteurs qui lui « gravitent » autour, le troisième temps met en perspective l’innovation à travers une approche par les résultats (partie 3). Cette troisième et dernière partie complète les approches par l’identification et par les moyens que nous avons précédemment développés. Elle propose une approche synthétique du lien entre innovation et territoire par l’intermédiaire des brevets. L’intérêt de cette démarche est de proposer une approche de l’innovation à travers un output reconnu. / The objective of this thesis is to establish by the slant of economic tools a better representativeness of a specific domain to the scale of a territory : the innovation. This research appears like an element of answer to a questioning of the Council Régional of Provence-Alpes-Cote d’Azur about the determination of the" potential innovating" regional. This institution is at the origin of this research.In a first part we try to understand and to analyze the tie between innovation and territory. For it we conduct in a first time the identification of the theoretical bases and we realize an analysis interrogative around this innovation / territory joint (chapter 1). Once the systemic character of the innovation put in evidence, our gait driven us in a second time to develop a territorial approach of the innovation (chapter 2). This approach fully finds sense in a third and last time where we apply to this innovation / territory tie the concept of "regional innovation system" (chapter 3).The second part of the thesis tries to understand the elements of the innovation on the regional territory of Provence-Alpes-Cote d’Azur. This approach takes place from the developed previously conceptual setting and that we consider here like the most applicable, the regional innovation system. First of all we elaborate a preview of the regional territory (chapter 4). It allows us to see what is the regional innovation system of Provence-Alpes-Cote d’Azur. On this fact we can develop an analysis of this system identified, and it through a reading in three times of the diagram of the regional innovation (chapters 5 and 6).This third and last part completes the approaches by the identification and by the means that we developed previously. We propose a synthetic approach of the tie between innovation and territory through the intermediary of the patents (chapters 7, 8 and 9). We also propose some elements of assessment of the regional performance from the activity of deposit of patents (chapter 10), and we try to determine if an impact clean to the territories exists

Analyse des Routenwahlverhaltens von Radfahrenden auf Grundlage GPS basierter Daten zum real beobachteten VerkehrsverhaltenHuber, Stefan 03 May 2022 (has links)
Eine an den Bedürfnissen von Radfahrer*innen orientierte Planung ist für die Förde-rung des Radverkehrs unumgänglich. Um den Ausbau der Radverkehrsinfrastruktur ent-sprechend zu planen, sind jedoch Informationen zum Routenwahlverhalten der Radfah-renden und dessen Einflussfaktoren notwendig. Mit diesen Informationen können z.B. Wirkungen von Maßnahmen oder die zukünftige Nutzung von geplanter Radverkehrsinf-rastruktur abgeschätzt werden.
Aus diesem Grund wurden vor allem in der letzten Dekade zahlreiche internationale Arbeiten vorangetrieben, die die Routenwahl auf Basis von GPS-basierten Daten zum real beobachteten Routenwahlverhalten untersuchten. Da die Studien meist für einzelne und nichtdeutsche Städte durchgeführt wurden, lassen sich die Ergebnisse jedoch nicht direkt auf den deutschen Raum übertragen.
Um die Einflussfaktoren der Routenwahl für den deutschen Raum zu untersuchen, wird in dieser Arbeit die Routenwahl von Radfahrenden im Raum Dresden analysiert. Ba-sis der Untersuchung stellt ein während der Aktion STADTRADELN erhobener GPS-Daten-satz dar, der 18.459 Radfahrten von 1.361 Radfahrer*innen enthält und Auskunft über deren real beobachtetes Routenwahlverhalten gibt. Die erhobenen Routendaten wurden mit unterschiedlichen Verfahren aufbereitet und über ein Verkehrsnetz mit Sekundärda-ten angereichert, sodass die Eigenschaften der gewählten Routen berechnet und den je-weils erzeugten und nicht gewählten Routenalternativen gegenübergestellt werden konn-ten. Der Einfluss der unterschiedlichen Faktoren wurde anschließend mittels logistischer Regressionsanalyse untersucht.
Das Ergebnis der Untersuchung zeigt auf, dass sich die folgenden Einflussfaktoren positiv auf die Routenwahl auswirken:
+ Existenz von Radverkehrsinfrastruktur
+ Geringe Längsneigungen
+ Gute Oberflächenbeschaffenheit (z.B. Asphalt)
+ Vorhandensein anderer Radfahrender entlang einer Route
+ Geringe zulässige Maximalgeschwindigkeit des motorisierten Verkehrs
+ Geringe Fahrstreifenanzahl des Kfz-Verkehrs
+ Durch Lichtsignalanlagen geregelte Knotenpunkte
+ Grün- und Wohngebietsflächen
Demgegenüber üben die folgenden Einflussfaktoren einen negativen Einfluss auf die Wahl einer Route aus:
– Zunehmende Distanz
– Hohe Streckenanteile mit großer Längsneigung
– Eine hohe maximale Längsneigung der Route
– Geringe Breite der Radverkehrsführung
– Höhere Unfallhäufigkeit entlang der Route
Für einige Einflussfaktoren konnte kein (signifikanter) Einfluss auf die Routenwahl nachgewiesen werden. Dazu gehören bspw. die durchschnittlich tägliche Verkehrsstärke des Kfz-Verkehrs, der ruhende Verkehr oder die Häufigkeit von „rechts-vor-links“ geregel-ten Knotenpunkten.
Die vorliegende Arbeit konnte dazu beitragen, die Wirkung der Einflussfaktoren auf die Routenwahl im Radverkehr einer deutschen Stadt zu quantifizieren. Eine Stärke der Untersuchung liegt in der Erhebung und Nutzung des umfangreichen GPS-Datensatzes zum real beobachteten Routenwahlverhalten der Radfahrer*innen. Das resultierende Routenwahlmodell kann für die Abschätzung von Maßnahmenwirkungen genutzt werden (z.B. im Rahmen der Verkehrsnachfragemodellierung).
Eine kritische Reflexion der Ergebnisse und Methoden zeigt, dass die Qualität der Ana-lyse und ihrer Ergebnisse durch die Nutzung weiterer Sekundär- und Primärdaten sowie anderer Methoden weiter verbessert werden kann.
Die Ergebnisse der Untersuchung geben einen Einblick in die Routenwahl der Radfah-renden des Untersuchungsgebiets. Im Rahmen der Arbeit konnte nicht geprüft werden, ob die Routenwahl der Radfahrer*innen in Dresden vergleichbar mit der Routenwahl in anderen deutschen Städten ist. Das entwickelte Verfahren kann jedoch auch für Analysen in anderen Städten angewendet werden, sodass verlässliche Aussagen zur Routenwahl deutscher Radfahrender in anderen deutschen Kommunen erarbeitet werden können.
Es lassen sich insgesamt folgende Schlussfolgerungen ziehen: Um den Radfahrenden eine möglichst attraktive Radverkehrsinfrastruktur zu bieten und damit die Nutzung des Fahrrads zu fördern, sollte der Radverkehr auf eigener Radverkehrsinfrastruktur geführt werden, die möglichst breit ist und eine gute Oberflächenqualität besitzt. Entlang der Rad-routen sollten die Geschwindigkeiten des fließenden motorisierten Verkehrs möglichst reduziert werden. Die Bündelung von Radverkehrsströmen sowie die Führung durch Grünflächen kann zudem Fahrtkomfort und Sicherheitsempfinden erhöhen. / User-oriented bicycle planning is essential for the promotion of cycling in cities. In order to adequately plan and build cycling infrastructure, information on route choice be-haviour of cyclists and its influencing factors is essential. The knowledge about influencing factors of bicycle route choice can help to assess the effect of measures as well as future or potential utilisation of planned cycling infrastructure.
Several international studies – particularly carried out in the last decade – examined route choice based on GPS-based revealed preference data. As the studies were mostly conducted for few and non-German cities the results, however, cannot be directly trans-ferred to the German area.
In order to investigate bicycle route choice for the German area, the route choice of cyclists in the city of Dresden is analysed in this study. The basis of the investigation is a GPS data set collected during the CITY CYCLING campaign. It contains 18,459 bicycle trips by 1,361 cyclists and provides detailed information about the observed route choice be-haviour of cyclists. The collected route data were processed by using different methods. Linking the routes to a traffic supply network allowed enriching them with secondary data so that characteristics of the selected routes and the non-selected generated alternatives were determined. The influence of the different factors was investigated using logistic re-gression analysis.
The results of the study reveal that the following influencing factors positively affect bicycle route choice:
+ Existence of cycling infrastructure
+ Low slopes
+ Good surface conditions (e.g. asphalt)
+ Presence of other cyclists along a route
+ Low maximum speed of motorised traffic
+ Few number of lanes for motorised traffic
+ Intersections controlled by traffic signals
+ Green and residential areas
In contrast, the following factors show a negative influence on bicycle route choice:
– Increasing distance
– High proportion of routes with steep longitudinal gradients
– A high maximum gradient along the route
– Narrow width of the cycle lane
– Higher accident frequency along the route
For some influencing factors, no (significant) influence on route choice was found (e.g. for the average daily traffic volume of motorized traffic, stationary traffic or the frequency of right-of-way regulated intersections).
The present study contributes to the quantification of influencing factors or rather their effect on bicycle route choice in a German city. Furthermore, the resulting route choice model can be used to estimate the effects of different measures (e.g. in the context of traffic demand modelling). A strength of the study is the extensive data set on revealed preferences of cyclists that has been used to analyse route choice behaviour.
A critical reflection of the results and methods shows that the quality of the analysis and its results could further be improved by using more secondary and primary data as well as other models for analysis.
The results of the study provide an insight into route choices of cyclists in the study area. However, it could not be determined whether route choice of cyclists in Dresden is similar to route choice of cyclists in other German cities. Nevertheless, the developed method could also be used to analyse route choice in other cities, so that reliable state-ments on route choice of German cyclists can be compiled.
Overall, the following conclusions can be drawn: in order to provide cyclists the most attractive cycling infrastructure possible and, thus, promote the use of cycling in cities, bicycle traffic should be guided on dedicated and wide cycling infrastructure with good surface quality. Furthermore, the speed of moving motorised traffic should be reduced along the route segments if possible. Bundling of cycling traffic flows and routing cyclists through green spaces can furthermore increase riding comfort and the perception of safety.

Management of Complex Sociotechnical SystemsTopcu, Taylan Gunes 20 April 2020 (has links)
Sociotechnical systems (STSs) rely on the collaboration between humans and autonomous decision-making units to fulfill their objectives. Highly intertwined social and technical contextual factors influence the collaboration between these human and engineered elements, and consequently the performance characteristics of the STS. In the next two decades, the role allocated to STSs in our society will drastically increase. Thus, the effective design of STSs requires an improved understanding of the human-autonomy interdependency.
This dissertation brings together management science along with systems thinking and uses a mixed-methods approach to investigate the interdependencies between people and the autonomous systems they collaborate within complex socio-technical enterprises. The dissertation is organized in three mutually exclusive essays, each investigating a distinct facet of STSs: safe management, collaboration, and efficiency measurement.
The first essay investigates the amount of work allocated to safety-critical decision makers and quantifies Rasmussen's workload boundary that represents the limit of attainable workload. The major contribution of this study is to quantify the qualitative theoretical construct of the workload boundary through a Pareto-Koopmans frontier. This frontier allows one to capture the aggregate impact of the social and technical factors that originate from operational conditions on workload.
The second essay studies how teams of humans and their autonomous partners share work, given their subjective preferences and contextual operational conditions. This study presents a novel integration of machine learning algorithms in an efficiency measurement framework to understand the influence of contextual factors. The results demonstrate that autonomous units successfully handle relatively simple operational conditions, while complex operational conditions require both workers and their autonomous counterparts to collaborate towards common objectives.
The third essay explores the complementary and contrasting roles of efficiency measurement approaches that deal with the influence of contextual factors and their sensitivity to sample size. The results are organized in a structured taxonomy of their fundamental assumptions, limitations, mathematical structure, sensitivity to sample size, and their practical usefulness.
To summarize, this dissertation provides an interdisciplinary and pragmatic research approach that benefits from the strengths of both theoretical and data-driven empirical approaches. Broader impacts of this dissertation are disseminated among the literatures of systems engineering, operations research, management science, and mechanical design. / Doctor of Philosophy / A system is an integrated set of elements that achieve a purpose or goal. An autonomous system (ADS) is an engineered element that often substitutes for a human decision-maker, such as in the case of an autonomous vehicle. Sociotechnical systems (STSs) are systems that involve the collaboration of a human decision-maker with an ADS to fulfill their objectives. Historically, STSs have been used primarily for handling safety critical tasks, such as management of nuclear power plants. By design, STSs rely heavily on a collaboration between humans and ADS decision-makers. Therefore, the overall characteristics of a STS, such as system safety, performance, or reliability; is fully dependent on human decisions. The problem with that is that people are independent entities, who can be influenced by operational conditions. Unlike their engineered counterparts, people can be cognitively challenged, tired, or distracted, and consequently make mistakes.
The current dependency on human decisions, incentivize business owners and engineers alike to increase the level of automation in engineered systems. This allows them to reduce operational costs, increase performance, and minimize human errors. However, the recent commercial aircraft accidents (e.g., Boeing 737-MAX) have indicated that increasing the level of automation is not always the best strategy. Given that increasing technological capabilities will spread the adoption of STSs, vast majority of existing jobs will either be fully replaced by an ADS or will change from a manual set-up into a STS. Therefore, we need a better understanding of the relationships between social (human) and engineered elements.
This dissertation, brings together management science with systems thinking to investigate the dependencies between people and the autonomous systems they collaborate within complex socio-technical enterprises. The dissertation is organized in three mutually exclusive essays, each investigating a distinct facet of STSs: safe management, collaboration, and efficiency measurement.
The first essay investigates the amount of work handled by safety-critical decision makers in STSs. Primary contribution of this study is to use an analytic method to quantify the amount of work a person could safely handle within a STSs. This method also allows to capture the aggregate impact of the social and technical factors that originate from operational conditions on workload.
The second essay studies how teams of humans and their autonomous partners share work, given their preferences and operational conditions. This study presents a novel integration of machine learning algorithms to understand operational influences that propel a human-decision maker to handle the work manually or delegate it to ADSs. The results demonstrate that autonomous units successfully handle simple operational conditions. More complex conditions require both workers and their autonomous counterparts to collaborate towards common objectives.
The third essay explores the complementary and contrasting roles of data-driven analytical management approaches that deal with the operational factors and investigates their sensitivity to sample size. The results are organized based on their fundamental assumptions, limitations, mathematical structure, sensitivity to sample size, and their practical usefulness.
To summarize, this dissertation provides an interdisciplinary and pragmatic research approach that benefits from the strengths of both theoretical and data-driven empirical approaches. Broader impacts of this dissertation are disseminated among the literatures of systems engineering, operations research, management science, and mechanical design.
