▼ This thesis focuses on modeling and optimization of two-region urban pricing systems and analyzing and understanding the effects of pricing on the network traffic flow. The motivation of this work is the fact that traffic congestion is growing fast in cities around the world especially in city centers, and hence the need for an effective and efficient travel demand management (TDM) policy. With the aim of advancing the current congestion pricing theory, this thesis proposes and integrates different advanced pricing regimes with the Network Fundamental Diagram (NFD) and simulation-based dynamic traffic assignment (DTA), studies and compares different computationally efficient simulation-based optimization (SO or SBO) methods, and analyzes and under-stands the effects of different pricing regimes on the network traffic flow.This thesis demonstrates through computer simulations the effectiveness of a well-designed pricing system on improving the network performance. The major finding is that the distance only toll, which represents the state of the practice, naturally drives travelers into the shortest paths within the pricing zone (PZ) resulting in a more uneven distribution of congestion and hence, a larger hysteresis loop in the NFD and lower network flows especially during network recovery. This limitation is overcome by two more advanced pricing regimes, namely the joint distance and time toll (JDTT) and the joint distance and delay toll (JDDT), through the introduction of a time and a delay toll component, respectively. Moreover, this thesis explicitly models and minimizes the heterogeneity of congestion distribution as part of the toll level problem (TLP). The toll area problem (TAP) is also investigated by means of network partitioning.To optimize different pricing regimes through computer simulations, this thesis develops two computationally efficient SO frameworks. The first framework employs a proportional-integral (PI) controller from control theory to solve a simple TLP featuring a low-dimensional decision vector, a set-point objective and only bound constraints. The second framework employs regressing kriging (RK) from machine learning to solve a complex TLP that has either a high-dimensional decision vector, a complex objective, or a set of complex constraints. A comprehensive comparison between the two methods and two other widely used methods, namely simultaneous perturbation stochastic approximation (SPSA) and DIviding RECTangles (DIRECT), are performed.Overall, this thesis provides valuable insights into the study, design, and implementation of urban pricing systems and the effects of pricing on the network traffic flow. Results of this work not only help in developing effective pricing systems to mitigate urban traffic congestion, but also provide competitive solutions to other types of network design problems (NDPs).

▼ A macroscopic relation between the network-level average flow-rate and density, which is known as the macroscopic fundamental diagram (MFD), has been shown to exist in urban networks in stationary states. In the literature, however, most existing studies have considered the MFD as a phenomenon of urban networks, and few have tried to derive it analytically from signal settings, route choice behaviors, or demand patterns. Furthermore, it is still not clear about the definition or existence of stationary traffic states in urban networks and their stability properties. This dissertation research aims to fill this gap. I start to study the stationary traffic states in a signalized double-ring network. A kinematic wave approach is used to formulate the traffic dynamics, and periodic traffic patterns are found using simulations and defined as stationary states. Furthermore, traffic dynamics are aggregated at the link level using the link queue model, and a Poincare map approach is introduced to analytically define and solve possible stationary states. Further results show that a stationary state can be Lyapunov stable, asymptotically stable, or unstable. Moreover, MFDs are explicitly derived such that the network flow-rate is a function of the network density, signal settings, and route choice behaviors. Also the time for the network to be gridlocked is analytically derived. Even with the link queue model, traffic dynamics are still difficult to solve due to the discrete control at signalized junctions. Therefore, efforts are also devoted to deriving invariant continuous approximate models for a signalized road link and analyzing their properties under different capacity constraints, traffic conditions, traffic flow fundamental diagrams, signal settings, and traffic flow models. Analytical and simulation results show that the derived invariant continuous approximate model can fully capture the capacity constraints at the signalized junction and is a good approximation to the discrete signal control under different traffic conditions and traffic flow fundamental diagrams. Further analysis shows that non-invariant continuous approximate models cannot be used in the link transmission model since they can yield no solution to the traffic statics problem under certain traffic conditions. For a signalized grid network, simulations with the link queue model confirm that important insights obtained for double-ring networks indeed apply to more general networks.

▼ Recently it has been proposed that the performance of a complete network can be represented graphically using only aggregated data for flow and density. The resulting graph is the macroscopic fundamental diagram (MFD), which relates the average flow (performance) to the number of vehicles in the network (accumulation). The resulting shape is often concave, meaning that the performance can be maximised if a fixed number of vehicles is maintained in the network (optimal accumulation). One of the most promising methods to achieve this, is by adapting signal timings. The objective of this thesis is to investigate if (1) a relationship between the shape of the MFD and the structure of the underlying network exists and on which factors this depends and (2) if the shape of the MFD of a subnetwork (neighbourhood) and its perimeter (ring of higher level roads (with signalised intersections) around a subnetwork) are affected by different signal timings and how this does affect the applicability of the MFD for control strategies. To assess the effect of the structure on the network, a tool has been developed to automatically generate fictitious networks with different structures, in which the amount of infrastructure and signal timings are matched dynamically to a randomly generated OD-matrix. The resulting networks are used as a base for the simulations, which are done in the microscopic traffic simulator VISSIM. Using various signal timings for signals located on the perimeter, the flow from the subnetwork to the perimeter is restricted and vice-versa, in order to assess how the MFD of both react to these changes. Regarding the relation between the shape of the MFD and the network structure, it is concluded that the structure of a network in itself does not have a strong influence on the shape of the MFD. Differences between MFDs are not caused by topological differences, but by the different characteristics of the roads (length, speed, capacity) and the amount and type of intersections in the underlying network. The different factors influencing the shape of the MFD could not be quantified – in order to construct MFDs based only on knowledge of the network and without the use of simulations - as the shape of the MFD is found to differ strongly, even for similar networks. As such it is concluded that the stochastic and dynamic nature of traffic has a strong influence on the shape of the MFD. Especially the accumulation is highly sensitive to differences in the distribution of traffic over the network, making the optimal accumulation particularly hard to predict. Regarding the effect of signal settings on the shape of the MFD of a subnetwork and its perimeter and its applicability for control strategies, it is concluded that a strong relation between the MFD of the subnetwork and its perimeter does exist, in which both react in the same way to changes in traffic demand and signal timings. The ratio between the performance of the subnetwork and perimeter is highly consistent and not strongly affected by changes in the signal… Advisors/Committee Members: Hoogendoorn, S.P.

La congestion en milieu urbain est un enjeu majeur que ce soit d’un point vue économique, social ou environnemental. À court et moyen terme, l’utilisation de la simulation dynamique du trafic routier peut permettre d’analyser et de guider des politiques d’optimisation des infrastructures existantes. Aujourd’hui, du fait de la complexité des systèmes de transport, les outils de modélisation classiques sont limités à des échelles géographiques peu étendues (de l’ordre du quartier). À grande échelle, le temps de calcul devient rapidement un facteur limitant tout comme le calibrage et la scénarisation. Néanmoins les dernières décennies ont vu l’apparition d’une nouvelle génération de modèles bien adaptés aux métropoles urbaines. Ceux-ci sont basés sur une relation phénoménologique entre la production de déplacements et le nombre de véhicules dans une zone spatiale d’un réseau routier, appelée Diagramme Fondamental de Zone (Macroscopic Fundamental Diagram, MFD). Cette relation, validée empiriquement sur de nombreuses villes, a permis d’étudier différentes méthodes de contrôle du trafic pour une ville entière, mais a été peu utilisée à des fins de prévision de la congestion. L’objectif de cette thèse est de proposer un premier outil opérationnel de simulation et d’analyse des grands réseaux de métropoles, en utilisant et développant les modèles de trafic basés sur la relation MFD. Cet outil doit posséder un cadre théorique cohérent qui puisse convenir à des applications telles que la prévision d’états de trafic, le développement de nouvelles politiques de contrôle, l’estimation de pollutions liées au trafic, etc. Les contributions de la thèse portent sur deux aspects. Le premier est l’analyse des propriétés mathématiques et physiques des modèles existants, en incluant une formalisation complète de la gestion de plusieurs longueurs de parcours au sein d’une même zone urbaine. En particulier, cette formalisation traite de la distinction des trajets internes à la zone et des problèmes de flux convergents et divergents pour les trajets traversant la zone lorsque la congestion se propage d’une zone à l’autre. Le deuxième aspect est la proposition d’un nouveau modèle basé sur la distance individuelle parcourue à l’intérieur d’une zone urbaine (trip-based). Cette approche permet d’individualiser les usagers (auparavant représentés sous forme de flux continus) et donc de définir plus finement leurs caractéristiques, en vue de coupler leurs déplacements à des modèles d’affectations sur différentes routes. Enfin, des exemples d’application illustrant diverses collaborations sont donnés en dernière partie de la thèse. La simulation du trafic sur l’aire urbaine du Grand Lyon (France) y est présentée, ainsi que de nouveaux modules de modélisation de la recherche de parking ou de contrôle périphérique. Cette thèse est partie intégrante d’un projet européen ERC intitulé MAGnUM : Approche multi-échelle et multimodale de la modélisation du trafic pour une gestion durable de la mobilité urbaine.

In recent decades, mitigating the traffic congestion in urban road networks has been a crucial issue for both the research and the practical operations, which calls for the development and implementation of improved traffic signal control methods and techniques. In particular, the development of efficient and practicable real-time signal control strategies under saturated traffic conditions is a major challenge, as widely used strategies like SCOOT and SCATS are deemed less efficient under saturated traffic conditions. A practical tool, frequently employed against over-saturation of significant or sensitive links, arterials or urban network parts, is gating. The idea is to hold traffic back (via prolonged red phases at traffic signals) upstream of the links to be protected from over-saturation, whereby the level or duration of gating may depend on real-time measurements from the protected links. The method is usually employed in an ad hoc way (based on engineering judgment and manual fine-tuning) regarding the specific gating policy and quantitative details, which may lead to insufficient or unnecessarily strong gating actions. Recently, the reproducible relationship between flow and density occurring at the network level under certain conditions (e.g. homogeneous spatial distribution of the congestion) known as macroscopic or network fundamental diagram (MFD or NFD), has gained increased popularity. Although the NFD notion is still under investigation in various aspects, it can be exploited as a fruitful basis for derivation of urban signal control approaches.In this thesis, the notion of NFD for urban networks is exploited to improve mobility in saturated traffic conditions via application of gating measures, based on an appropriatesimple feedback control structure. Different gating control strategies (i.e. single perimeter gating control by exploiting complete and reduced NFD, multiple-concentric gating control, perimeter traffic control via remote feedback gating) have been proposed and tested on realistic simulation scenarios of two urban networks (i.e. Chania, Greece and San Francisco, USA) successfully. In the investigated examples, feedback gating is demonstrated to lead to substantial improvements of travel delays, network throughput and travel time reliability.
