Abstract:
Les impacts négatifs des déchets dispersés dans l’environnement sont soulignés depuis des décennies, mais peu de données de terrain sont disponibles dans la littérature scientifique. Les eaux pluviales peuvent contribuer de façon importante à la propagation et à l’accumulation de débris plastiques dans l’environnement. Toutefois, peu de données existent sur les flux et la composition des macrodéchets dans les eaux pluviales, y compris les débris plastiques. Afin de combler ce manque de connaissances, cette étude a pour objectif d’étudier l’occurrence, l’abondance et la composition des macrodéchets issus du trafic routier. Pour y répondre, les macrodéchets, dont les débris plastiques, ont été collectés dans un bassin de rétention des eaux pluviales drainant une portion du périphérique nantais pendant une année. Cette portion correspond à la partie sud du pont de Cheviré qui présente un trafic important (~90 000 véhicules/jour en moyenne). Les macrodéchets sont triés et classés selon la classification Ospar/TG-ML. En un an, 88,5 kg de débris ont été collectés. Au total, les plastiques correspondent à 60 % de la masse de déchets récoltés. Ces déchets plastiques sont surtout des fragments, des mégots et filtres de cigarettes, ainsi que des morceaux de polystyrène. Une identification des sources de rejets a été réalisée en différenciant les déchets jetés volontairement (37,2 %), des déchets perdus accidentellement (62,8 %), parmi les 43 % de déchets pour lesquels cette différenciation était possible. La masse de déchets collectée est fortement corrélée au trafic. Ces résultats démontrent que les routes peuvent avoir une contribution importante dans les fuites de déchets, y compris les plastiques, vers les environnements récepteurs.

Abstract:
Les systèmes de transport jouent un rôle primordial dans le développement de la croissance économique des pays. Cependant, l'apparition des véhicules autonomes et électriques et les restrictions mises en place pour limiter la diffusion et les impacts du Covid-19 dans les transports en commun ont eu un impact important sur l’augmentation des problèmes de transport notamment aux intersections. Le présent papier aide à résoudre ces problèmes. Cet article s'intéresse à la modélisation stochastique des flux du trafic sur les réseaux routiers, grâce à des modèles macroscopiques génériques de second ordre : la famille GSOM. Il a été montré que de tels modèles d'ordre supérieur peuvent être résolus dans un cadre lagrangien dont les coordonnées lagrangiennes se déplacent avec le trafic. La difficulté d'utiliser cette solution de résolution sur un réseau est de traiter les discontinuités eulériennes – fixes – telles que les jonctions. L'objectif de ce travail est double : d'une part, proposer des modèles d’intersection adaptés aux modèles stochastiques macroscopiques de flux de trafic de second ordre, et d'autre part, résoudre le modèle résultant dans le cadre d’un réseau routier. Quelques exemples numériques sont fournis pour montrer l'efficacité de l'approche proposée.

Abstract:
Les accidents routiers impliquant l’orignal engendrent des dégâts matériels coûteux et peuvent causer des pertes de vies humaines. Nous avons étudié le comportement de l’orignal près des routes afin de développer des mesures d’atténuation pour réduire le nombre d’accidents routiers avec cette espèce. Nous avons muni plusieurs orignaux de colliers GPS entre 2003 et 2006 dans le nord de la réserve faunique des Laurentides, où se trouvent deux routes principales asphaltées et un réseau de chemins forestiers. Les axes routiers, même les chemins forestiers où le trafic était faible, furent généralement évités par les orignaux. Nos résultats suggèrent que la fréquentation par l’orignal des abords de routes pavées s’explique par la présence de sodium dans les mares d’eau stagnante. Cependant, la fréquentation des routes par l’orignal n’a pas augmenté en période d’abondance d’insectes piqueurs. Les abords des routes asphaltées ont généralement été visités au printemps et en été, périodes durant lesquelles les besoins en sodium de l’orignal sont les plus élevés. La présence de mares salines en bordure des routes augmente le risque de collision avec un orignal. L’élimination de ces mares pourrait donc améliorer sensiblement la sécurité routière, mais l’efficacité de cette approche à long terme n’est pas connue.

Abstract:
À l’époque romaine, le Massif central est décrit par les sources textuelles comme un secteur délicat en termes de circulation routière. Dans cette région où les zones montagneuses couvrent les quatre cinquièmes de la superficie du territoire, la chaîne des Puys, la Haute-Combraille et le massif du Devès sont aujourd’hui encore considérés comme des points de passage difficiles. Traversés par des axes antiques de moyen et long parcours, ces trois espaces offrent de fortes contraintes climatiques (couverture neigeuse, vents vigoureux, cycles de gel et dégel) et topographiques (pentes, dénivellations) qui devaient considérablement peser sur la viabilité, notamment hivernale. Cette contribution propose de s’intéresser à la qualité des infrastructures de transport et à la gestion du trafic routier dans ces zones de relief.

Abstract:
Nous considérons deux modèles EDP-EDO couplés: un pour modéliser des goulots d’étranglementmobiles et l’autre pour décrire la distribution du trafic sur une bretelle d’accès. Le premier modèle a étéintroduit pour décrire le mouvement d’un bus, qui roule à une vitesse inférieure à celle des autresvoitures, en réduisant la capacité de la route et générant ainsi un goulot d’étranglement. Une loi deconservation scalaire avec une contrainte mobile sur le flux décrit le trafic et une EDO décrit latrajectoire du bus. Nous présentons un résultat d’existence des solutions du modèle et nous proposonsune méthode numérique “front/capturing" et une méthode basée sur une technique de reconstructiondes ondes de chocs. Dans la deuxième partie, nous introduisons un nouveau modèle macroscopique dejonction pour les bretelles d’autoroute. Nous considérons le modèle de trafic de Lighthill-Whitham-Richards sur une jonction composée d’une voie principale, une bretelle d’accès et une bretelle de sortie,toutes reliées par un nœud. Une loi de conservation scalaire décrit l’évolution de la densité des véhiculessur la voie principale et une EDO décrit l’évolution de la longueur de la file d’attente sur la bretelled’accès. La définition de la solution du problème de Riemann à la jonction est basée sur la résolutiond’un problème d’optimisation linéaire et sur l’utilisation d’un paramètre de priorité. Ensuite, ce modèleest étendu aux réseaux et discrétisé en utilisant un schéma de Godunov qui prend en compte les effetsde la bretelle d’accès. Enfin, nous présentons un modèle d’optimisation de la circulation sur les ronds points
In this thesis we consider two coupled PDE-ODE models. One to model moving bottlenecks and theother one to describe traffic flow at junctions. First, we consider a strongly coupled PDE-ODE systemthat describes the influence of a slow and large vehicle on road traffic. The model consists of a scalarconservation law accounting for the main traffic evolution, while the trajectory of the slower vehicle isgiven by an ODE depending on the downstream traffic density. The moving constraint is expressed byan inequality on the flux, which models the bottleneck created in the road by the presence of the slowerDépôt de thèse – Donnéescomplémentairesvehicle. We prove the existence of solutions to the Cauchy problem for initial data of bounded variation.Moreover, two numerical schemes are proposed. The first one is a finite volume algorithm that uses alocally nonuniform moving mesh. The second one uses a reconstruction technique to display thebehavior of the vehicle. Next, we consider the Lighthill-Whitham-Richards traffic flow model on ajunction composed by one mainline, an onramp and an offramp, which are connected by a node. Theonramp dynamics is modeled using an ordinary differential equation describing the evolution of thequeue length. The definition of the solution of the Riemann problem at the junction is based on anoptimization problem and the use of a right of way parameter. The numerical approximation is carriedout using a Godunov scheme, modified to take into account the effects of the onramp buffer. Aftersuitable modification, the model is used to solve an optimal control problem on roundabouts. Two costfunctionals are numerically optimized with respect to the right of way parameter

Abstract:
Cette thèse est dédiée à l'étude mathématique de quelques modèles de trafic routier congestionné. La notion essentielle est l'équilibre de Wardrop. Elle poursuit des travaux de Carlier et Santambrogio avec des coauteurs. Baillon et Carlier ont étudié le cas de grilles cartésiennes dans $\RR^2$ de plus en plus denses, dans le cadre de la théorie de $\Gamma$-convergence. Trouver l'équilibre de Wardrop revient à résoudre des problèmes de minimisation convexe. Dans le chapitre 2, nous regardons ce qui se passe dans le cas de réseaux généraux, de plus en plus denses, dans $\RR^d$. Des difficultés nouvelles surgissent par rapport au cas initial de réseaux cartésiens et pour les contourner, nous introduisons la notion de courbes généralisées. Des hypothèses structurelles sur ces suites de réseaux discrets sont nécessaires pour s'assurer de la convergence. Cela fait alors apparaître des fonctions qui sont des sortes de distances de Finsler et qui rendent compte de l'anisotropie du réseau. Nous obtenons ainsi des résultats similaires à ceux du cas cartésien. Dans le chapitre 3, nous étudions le modèle continu et en particulier, les problèmes limites. Nous trouvons alors des conditions d'optimalité à travers une formulation duale qui peut être interprétée en termes d'équilibres continus de Wardrop. Cependant, nous travaillons avec des courbes généralisées et nous ne pouvons pas appliquer directement le théorème de Prokhorov, comme cela a été le cas dans \cite{baillon2012discrete, carlier2008optimal}. Pour pouvoir néanmoins l'utiliser, nous considérons une version relaxée du problème limite, avec des mesures d'Young. Dans le chapitre 4, nous nous concentrons sur le cas de long terme, c'est-à-dire, nous fixons uniquement les distributions d'offre et de demande. Comme montré dans \cite{brasco2013congested}, le problème de l'équilibre de Wardrop est équivalent à un problème à la Beckmann et il se réduit à résoudre une EDP elliptique, anisotropique et dégénérée. Nous utilisons la méthode de résolution numérique de Lagrangien augmenté présentée dans \cite{benamou2013augmented} pour proposer des exemples de simulation. Enfin, le chapitre 5 a pour objet l'étude de problèmes de Monge avec comme coût une distance de Finsler. Cela se reformule en des problèmes de flux minimal et une discrétisation de ces problèmes mène à un problème de point-selle. Nous le résolvons alors numériquement, encore grâce à un algorithme de Lagrangien augmenté
This thesis is devoted to the mathematical analysis of some models of congested road traffic. The essential notion is the Wardrop equilibrium. It continues Carlier and Santambrogio's works with coauthors. With Baillon they studied the case of two-dimensional cartesian networks that become very dense in the framework of $\Gamma$-convergence theory. Finding Wardrop equilibria is equivalent to solve convex minimisation problems.In Chapter 2 we look at what happens in the case of general networks, increasingly dense. New difficulties appear with respect to the original case of cartesian networks. To deal with these difficulties we introduce the concept of generalized curves. Structural assumptions on these sequences of discrete networks are necessary to obtain convergence. Sorts of Finsler distance are used and keep track of anisotropy of the network. We then have similar results to those in the cartesian case.In Chapter 3 we study the continuous model and in particular the limit problems. Then we find optimality conditions through a duale formulation that can be interpreted in terms of continuous Wardrop equilibria. However we work with generalized curves and we cannot directly apply Prokhorov's theorem, as in \cite{baillon2012discrete, carlier2008optimal}. To use it we consider a relaxed version of the limit problem with Young's measures. In Chapter 4 we focus on the long-term case, that is, we fix only the distributions of supply and demand. As shown in \cite{brasco2013congested} the problem of Wardrop equilibria can be reformulated in a problem à la Beckmann and reduced to solve an elliptic anisotropic and degenerated PDE. We use the augmented Lagrangian scheme presented in \cite{benamou2013augmented} to show a few numerical simulation examples. Finally Chapter 5 is devoted to studying Monge problems with as cost a Finsler distance. It leads to minimal flow problems. Discretization of these problems is equivalent to a saddle-point problem. We then solve it numerically again by an augmented Lagrangian algorithm

Abstract:
La cancérogénicité du benzène à forte dose (CIRC, Groupe 1) a été démontrée sur la base des cas de leucémies observés dans les études épidémiologiques conduites en milieu professionnel chez l’adulte exposé à de fortes doses. Ce polluant est émis en faible concentration dans l’environnement, notamment par le trafic routier et les stations-service. L’objectif est d’étudier le lien entre exposition au benzène à faible dose et risque de leucémie chez l’enfant. L’étude GEOCAP regroupe les cas de leucémies de l’enfant diagnostiqués en France entre 2002 et 2007 issus du Registre National des Hémopathies de l’Enfant, et un échantillon de 30 000 témoins représentatif de la population générale pédiatrique. La longueur de routes à fort trafic a été calculée au voisinage de la résidence de chaque sujet géocodé dans un rayon de 150 m. Les concentrations en benzène et en NO2 ont été estimées pour l’ensemble des sujets de France continentale à une échelle de 2 km2. La distance à la station-service la plus proche a également été calculée depuis la résidence de chaque sujet. La longueur de routes au voisinage de la résidence était positivement et significativement associée au risque de leucémie aigüe myéloblastique (LAM). La prise en compte des expositions au benzène et en NO2 renforçait cette association. La distance à la station-service la plus proche était positivement mais non-significativement associée à la LAM, et cette association résultait en partie d’un effet de confusion de la longueur de routes au voisinage de la résidence. Ce travail soutient l’hypothèse selon laquelle l’exposition au benzène émis dans l’environnement pourrait induire une augmentation du risque de LAM chez l’enfant
In adults, the relationship between benzene exposure (IARC, Group 1) and leukemia has been demonstrated in workplace for high-level exposure. This pollutant is emitted at low concentration in environment, especially by road traffic and petrol stations. The objective was to investigate the relationship between benzene exposure at low-level dose and childhood leukemia. The record-based GEOCAP study included all cases of childhood leukemia diagnosed in France over 2002-2007 and 30,000 contemporaneous population-based control children highly representative of the source population. The length of major roads was calculated around the residence of each geocoded subject in a 150-m buffer. We assigned them the yearly estimates of benzene and NO2 concentrations at the square where his residence was located on a 2-km2 grid covering continental France. The distance to the nearest petrol station from the residence was also calculated for all subjects. The length of major roads around the residence was positively and significantly associated with the risk of acute myeloblastic leukemia (AML). This association was more evident with benzene and NO2 2-km estimates, combined with the length of major roads indicator to enhance the exposure contrasts. The distance to the nearest petrol station was positively but non-significantely associated with AML, and some of this association was explained by a confouding effect of the length of major roads around the residence. This work suggests that exposure to benzene emitted in environment may increase the risk of AML in children

Nous proposons, dans cette thèse, un capteur visuel catadioptrique optimal en vue d'une application au diagnostic du trafic routier permettant de remplacer profitablement un réseau de caméras perspectives. Le système proposé a l'avantage, par le nombre et la conception des miroirs calculés, de générer une vue unique de la couronne du carrefour et de ses voies en maximisant le nombre de pixels utiles. Il en résulte une image où le pourcentage de pixels directement exploitables pour les phases ultérieures de traitement d'image est optimal. Nous décrivons la méthodologie utilisée pour concevoir un tel capteur. Afin de tester notre capteur, nous avons également développé les traitements d'images, qui fournissent les indicateurs utiles à l'estimation de l'activité du carrefour, à savoir, le taux d'occupation, la vitesse des véhicules et le débit. Le capteur ainsi conçu a été comparé avec des caméras utilisant différentes formes standard de miroirs (sphérique, parabolique, hyperbolique et miroirs ayant la résolution constante horizontale). Cette validation a montré que ce capteur est plus robuste et plus précis
In this thesis we present an optimal omnidirectional visual sensor which can replace perspective camera network for traffic diagnosis. The proposed system has the advantage, by the number and the designed mirror, to generate a single view of the crown and junction ways of the crossroads by maximizing the number of useless pixels. So, the percentage of pixels used directly for subsequent phases of image processing is optimal. We describe the methodology used to design such a sensor. In addition, to assess our sensor, we also developed image processing methods that provide useful indicators for estimating the state of the traffic as the crossroads occupancy rate, the vehicle speed and the flow of vehicles. We compare this optimal sensor to the traditional ones that used parabolic, hyperbolic, spherical mirror or a mirror that has constant horizontal resolution to observe the scene. We prove that optimal sensor has better results than traditional ones

Abstract:
Le domaine de la modélisation du trafic routier vise à comprendre son évolution. Dans les dernières années, plusieurs modèles du trafic ont été proposés dans l’objectif de géolocaliser les embouteillages au sein du trafic, détecter des motifs dans le trafic routier, estimer l’état du trafic etc. La plupart des modèles proposés considèrent le trafic routier en termes de ses constituants ou comme une entité agrégée en fonction de l’échelle choisie et expliquent l’évolution du trafic quantitativement en tenant compte des relations entre les variables de trafic comme le flot, la densité et la vitesse. Ces modèles décrivent le trafic en utilisant des données très précises acquises par différents capteurs. La précision des données rend son calcul coûteux en termes de ressources requises. Une des solutions à ce problème est la représentation qualitative du trafic routier qui réduit le nombre de ressources de traitement nécessaires. Puisque le trafic routier est un phénomène spatio-temporel, les modèles proposés pour représenter ce type de phénomène pourraient être appliqués dans le cas du trafic routier. Les modèles spatio-temporels, proposés par la communauté de l’Analyse Spatio-Temporelle, ont comme objectif la représentation d’un phénomène tant du point de vue qualitatif que quantitatif. Certains de ces modèles proposent une discrétisation des phénomènes modélisés en considérant un phénomène comme constitué d’entités. Appliquée au trafic routier, cette notion permet d’identifier différentes entités, comme les véhicules, les piétons, les bâtiments etc., qui le constituent. Ces entités influent sur l’évolution du trafic. Les modèles spatio-temporels qualitatifs définissent l’effet des différentes entités les unes sur les autres en terme de relations spatiales. L’évolution spatio-temporelle du phénomène modélisé est représenté par la variation temporelle de ces relations. La prise en compte des entités du trafic et des relations spatiales formalise une structure qui peut être représentée en utilisant un graphe, où les nœuds modélisent des entités et les arcs des relations spatiales. Par conséquent, l’évolution du trafic, modélisée via ce graphe, devient l’évolution du graphe et peut être représenté en terme de la variation de la structure du graphe ainsi que celle des attributs de ses nœuds et de ses arcs. Dans cette thèse, nous proposons une modélisation du trafic routier de ce type basée sur la théorie des graphes. Une des applications à la modélisation du trafic routier est la détection des motifs pertinents au sein du trafic. Dans les modèles du trafic existants, les motifs détectés sont statistiques et sont représentés en utilisant des caractéristiques numériques. Le modèle que nous pro posons dans cette thèse met en avant la structure représentant le trafic routier et peut donc être utilisé pour définir des motifs structurels du trafic qui prennent en compte des différentes entités du trafic et leurs relations. Ces motifs structurels sont sous-jacents à une modélisation sous forme de graphe dynamique. Dans cette thèse, nous proposons un algorithme pour détecter ces motifs structurels du trafic dans le graphe spatio-temporel représentant le trafic routier. Ce problème est formalisé comme celui de l’isomorphisme de sous-graphe pour des graphes dynamiques. L’algorithme proposé est évalué en fonction desdifférents paramètres de graphes
For past several decades, researchers have been interested in understanding traffic evolution, hence, have proposed various traffic models to identify bottleneck locations where traffic congestion occurs, to detect traffic patterns, to predict traffic states etc. Most of the existing models consider traffic as many-particle system, describe it using different scales of representation and explain its evolution quantitatively by deducing relations between traffic variables like flow, density and speed. Such models are mainly focused on computing precise information about traffic using acquired traffic data. However, computation of such precise information requires more processing resources. A way to remedy this problem is to consider traffic evolution in qualitative terms which reduces the required number of processing resources. Since traffic is spatio-temporal in nature, the models which deal with spatio-temporal phenomenon can be applied in case of traffic. Such models represent spatio-temporal phenomenon from qualitative as well as quantitative standpoints. Depending on the intended application, some models are able to differentiate between various entities taking part in the phenomenon, which proves useful in case of traffic since different objects like vehicles, buildings, pedestrians, bicycles etc., directly affecting traffic evolution, can be included in traffic models. Qualitative spatio-temporal models consider the effects of different entities on each other in terms of spatial relations between them and spatio-temporal evolution of the modeled phenomenon is described in terms of variation in such relations over time. Considering different traffic constituents and spatial relations between them leads to the formation of a structure which can be abstracted using graph, whose nodes represent individual constituents and edges represent the corresponding spatial relations. As a result, the evolution of traffic, represented using graph, is described in terms of evolution of the graph itself, i. e. change in graph structure and attributes of nodes and edges, with time. In this thesis, we propose such a graph model to represent traffic. As mentioned above, one of the applications of existing traffic models is in detecting traffic patterns. However, since such models consider traffic quantitatively, in terms of acquired traffic data, the patterns detected using such models are statistical (a term employed by Pattern Recognition researchers) in the sense that they are represented using numerical description. Since graph-based traffic model proposed in this thesis represents the structure of traffic, it can be employed to redefine the meaning of traffic patterns from statistical to structural (also a term from Pattern Recognition community). Structural traffic patterns include different traffic constituents and their inter-links and are represented using time-varying graphs. An algorithm to detect a given structural traffic pattern in the spatio-temporal graph representing traffic is proposed in this thesis. It formalizes this problem as subgraph isomorphism for time-varying graphs. In the end, the performance of the algorithm is tested using various graph parameters

Abstract:
AbstractLogit Model is an important method for empirical analysis of multi-source data. In order to explore the traffic safety mechanism, The Paper taked traffic behavior data as an example, researched personal characteristics of truck drivers, Analyzed the influence of the driver’s personal traits on traffic violations. Based on the binary logistics regression model, the analysis model of traffic violations was established. The results show that personality, driver’s license level, daily driving time, transportation route, vehicle ownership, and occupational disease are important factors that affect drivers’ violations. Further data analysis shows that truck drivers with bile personalities, driving for more than 12 h per day, no fixed transportation routes, and vehicles with loans have the highest probability of violations. The data analysis conclusion provides data basis for truck driver management and improving truck traffic safety.

AbstractThis chapter presents the application of the fuel assessment methodology developed in the Connecting Austria project. Thereby, a route analysis for an Austrian fleet operator is performed including the assessment of feasible and economic viable routes and scenarios. Furthermore, potential fuel consumption and CO$$_{2}$$ 2 emission savings are discussed within the given case. The saving potential may be increased via dynamic C-ITS-based truck platoon regulations, instead of statically defined, too restrictive regulations as indicated in the C-ITS assessment section. Finally, the chapter discusses the effect of truck platooning on increasing traffic efficiency.

Abstract:
The efficiency of buffers in network routers plays an important role in effectively accommodating packets that arrive in bursts at the routers interfaces. The choice of a suitable router buffer size is still a significant problem. Since, the use of small buffer guarantees low packet delay but higher chances of packet lost. Similarly, larger buffer leads to buffer bloat which causes higher delay in a network resulting to poor Quality of Service (QoS). Buffer bloat is a significant problem due to the high changing link characteristics of modern heterogeneous network traffics. The access links can have connections with speedy links (Gbps) with small amount of packet losses and have connection with a susceptible high packet loss with low-bandwidth links like wireless and last mile connections. Hence, what may be thought to be a rational buffer size might be flawed when link rates and delay fall below the minimum value. Thus, this paper analyses buffer size performance and optimization in networks with heterogeneous traffics for Random Early Detection (RED) Queues using NS2 simulations to obtain a range of better suited buffer sizes that improve the QoS without extra signaling and computation by routers. The results obtained established that having a buffer size between five to ten kilobytes yielded best average throughput with low average delay for RED Queue at the congested router Interface. In addition, the optimized buffer size scheme improved the QoS accordingly. Keywords: Buffer Size, Network Traffic, Quality of Service, Simulation

Abstract:
Smart urban mobility emerged from the urban citizen’s need for a fast urbanization environment, using personal devices and city infrastructure integration, data generation, and mobility services provided on congested and possibly dangerous urban roads. However, traditional routing services need to consider users’ experience, comfort and health because they usually choose only routes with the shortest paths or less traffic. This work proposes a route selection method based on a personalized preference for different user profiles, and essential geolocated factors from data collection, including crime occurrences and air quality factors. The suggestion method allows safer, healthier, and more pleasant paths for drivers and analytic data for city planners compared to single-criteria route selection approaches.

Abstract:
In recent years, European ports have, due to the increasing traffic between the Far East and Europe, become increasingly important. Large volumes of freight come to ships and it is important to have a link to the mainland via railway, which should have a functional overall system. This research compares three variants of possible routes for railway freight transport from the North Adriatic ports of Rijeka, Koper, and Trieste to Žilina, in the north of Slovakia. The methodology for calculating the minimum package of train access charges for the countries covered by these routes is presented. A comparative analysis of train access charges (TAC) for the minimum access package for the corridors between North Adriatic ports and City of Žilina has also been conducted. The result entailed in this research is the most favourable railway route for freight transport from the North Adriatic ports to the City of Žilina.

Abstract:
Vehicular traffic re-routing is the key to provide better vehicular mobility. However, considering just traffic-related information to recommend better routes for each vehicle is far from achieving the desired requirements of a good Traffic Management System (TMS), which intends to improve mobility, driving experience, and safety of drivers and passengers. In this scenario, context-aware and multi-objective re-routing approaches will play an important role in traffic management, considering different urban aspects that might affect path planning decisions such as mobility, distance, fuel consumption, scenery, and safety. There are at least three issues that need to be handled to provide an efficient TMS, including: (i) scalability; (ii) re-routing efficiency; and (iii) reliability. In this way, this thesis contributes to efficient and reliable solutions to meet future TMSs. The proposed solutions were widely compared with other related works on different performance evaluation metrics. The evaluation results show that the proposed solutions are efficient, scalable, and cost-effective, pushing forward state-of-the-art traffic management systems.

Full text
Abstract:
Traffic sign visual information provides road users with the basic instructions regarding route selection, safety at intersections, warnings on physical obstacles on the road and safe route marking. The use of sophisticated eye tracking systems is an efficient way to analyse the influence of traffic signs on drivers’ behaviour. In this paper, the drivers’ perception of traffics signs has been analysed using such a system. The aim of this paper is to determine how the perception of traffic signs changes according to the frequency of driving on a specific route or according to the route familiarity. The results show that the drivers’ perception of traffic signs declines as they get familiar with the route and road conditions. In addition, older drivers having more driving experience perceive fewer signs and elements from the environment because they are often led by their own experience and knowledge, so they do not need the same amount of information as compared to younger drivers.

Abstract:
Accurate and reliable traffic state estimation is essential for the identification of congested areas and bottleneck locations. It enables the quantification of congestion characteristics, such as intensity, duration, reliability, and spreading which are indispensable for the deployment of appropriate traffic management plans that can efficiently ameliorate congestion problems. Similarly, it is important to categorize known congestion patterns throughout a long period of time, so that corresponding traffic simulation models can be built for the investigation of the performance of different traffic management plans. This study conducts cluster analysis to identify days with similar travel conditions and congestion patterns. To this end, travel, traffic and weather data from the Smart Mobility Living Lab of Thessaloniki, Greece is used. Representative days per cluster are determined to facilitate the development of traffic simulation models that typify average traffic conditions within each cluster. Moreover, spatio-temporal matrices are developed to illustrate time-varying traffic conditions along different routes for the representative days. Results indicate that the proposed clustering technique can produce valid classification of days in groups with common characteristics, and that spatio-temporal matrices enable the development of traffic management plans which encompass routing information for competing routes in the city of Thessaloniki.

Abstract:
Intelligent Transport Systems (ITS) arose as a modern solution to traffic jams and vehicle accidents in the urban environment. A key part of the ITS is Traffic Management (TM), which concerns the planning and route definition of the vehicle. Existing TM solution focuses specifically on urban traffic information, ignoring the issues related to the network infrastructure and the applications at the top of it. Within this context, this paper presents a vehicle routing and re-routing strategy, called DINO, that considers both travel time of vehicles on the roads and the active network flows in the network, aiming to dynamically bring a suitable balance between travel time and packet delivery through a heuristic. The experiments performed suggest that DINO improves the packet delivery of the applications while reduces the average travel time of vehicles.

Abstract:
Route planning and recommendation have attracted much attention for decades. In this paper, we study a continuous optimal route combination problem: Given a dynamic road network and a stream of trip queries, we continuously find an optimal route combination for each new query batch over the query stream such that the total travel time for all routes is minimized. Each route corresponds to a planning result for a particular trip query in the current query batch. Our problem targets a variety of applications, including traffic-flow management, real-time route planning and continuous congestion prevention. The exact algorithm bears exponential time complexity and is computationally prohibitive for application scenarios in dynamic traffic networks. To address this problem, a self-aware batch processing algorithm is developed in this paper. Extensive experiments offer insight into the accuracy and efficiency of our proposed algorithms.

Abstract:
The present study was initiated by the Illinois Department of Transportation (IDOT) to better understand characteristics of roadway segments categorized as unmarked in IDOT’s Transportation Asset Management Plan and to suggest recommendations to manage, vacate, abandon, retain, or transfer individual routes. The researchers developed a methodology, labeled JARM, to identify potential candidates for jurisdictional transfer, abandonment (or vacation), reconfiguration, or maintenance. The JARM methodology is an easy-to-use and stand-alone spreadsheet tool for IDOT districts. It includes all unmarked routes as well as their key database variables and visual attributes. The study identified that over 90% of unmarked route centerline mileage is recommended for jurisdictional transfer to move off IDOT’s inventory and to be better served by local agencies, while reducing maintenance costs and future funding needs. To identify maintenance strategies for unmarked routes and low-volume roads, the researchers reviewed best practices of various state agencies and developed treatment catalogues for rural and urban routes. Additionally, they conducted two surveys: (1) a survey of other state DOTs to understand management of similar routes and (2) a survey of local public agencies within Illinois to understand their familiarity and willingness to accept unmarked routes. Twenty-five DOTs responded to the survey to provide insight into how they manage similar routes. The results demonstrated that 70% of local public agency respondents were amenable to a discussion of jurisdictional transfer. The next logical step is to build off this network-level research and to identify execution strategies at the project level in the most cost-effective manner.

Abstract:
Maintenance of traffic (MOT) during construction periods is critical to the success of project delivery and the overall mission of transportation agencies. MOT plans may include full road closures and coordination of detours near construction areas. Various state DOTs have designed their own manuals for detour mapping and coordination. However, very limited information is provided to select optimal detour routes. Moreover, closures or detours should provide not only measurable consequences, such as vehicle operating costs and added travel time, but also various unforeseen qualitative impacts, such as business impacts and inconvenience to local communities. Since the qualitative aspects are not easily measurable they tend to be neglected in systematic evaluations and decision-making processes. In this study, the current practices obtained based on an extensive literature review, a nation-wide survey, as well as a series of interviews with INDOT and other state DOTs are leveraged to (1) identify a comprehensive set of Key Performance Indicators (KPIs) for detour route mapping, (2) understand how other state DOTs address the qualitative criteria, (3) identify how the involved risks during the planning, service time, and closure of the detour routes are managed, and (4) recommend process improvements for INDOT detour mapping guidelines. As demonstrated by two sample case studies, the proposed KPIs can be taken as a basis for developing a decision-support tool that enables decision-makers to consider both qualitative and quantitative aspects for optimal detour route mapping. In addition, the current INDOT detour policy can be updated based on the proposed process improvements.
