Le trafic routier englobe plusieurs facteurs, entre autres la géométrie des infrastructures routières, le comportement des conducteurs, la diversité des flux de véhicules,etc...Les situations auxquelles sont confrontés les exploitants des réseaux routiers dépendent du type de réseau dont ils ont la charge. Cette complexité du trafic en a fait un domaine de recherche d'un intérêt croissant et ce depuis les premières études qui ont donné naissance au modèle LWR au milieu des années cinquante. Afin de modéliser le trafic sur un réseau routier, deux approches, complémentaires l'une de l'autre sont nécessaires. La première est la modélisation de l'écoulement qui permet de décrire l'évolution des flux de trafic sur un tronçon de route et l'affectation qui décrit la façon dont les usagers choisissent leurs itinéraire sur un réseau. L'objet de ces travaux de thèse est d'apporter une contribution à cette amélioration de la modélisation des flux de trafic, en se concentrant dans un premier lieu sur la modélisation d'un trafic autoroutier constitué de deux classes de véhicules: des véhicules particuliers et des bus. L'étude numérique du modèle se fait en adaptant le modèle de transmission cellulaire de Daganzo. Un estimateur des densités et autre des vitesses de ce trafic mixte sur un tronçon de route ont été présentés. Des résultats de stabilité dans les différents régimes de ce trafic ont été établis. Dans un second lieu sur la modélisation d'un trafic urbain multimodal constitué de trois classes de véhicules: aux deux classes précedement citées, est intégrée une nouvelle classe de bus à haut niveau de service BHNS ou BRT, classe qui tend à se propager au milieu urbain et suburbain et qui est perçue comme solution à de nombreux problèmes liés au trafic par les exploitants de la route.Nous proposons deux modèles pour modéliser la progression du BRT sur le réseau, puis nous développons une stratégie de régulation de ce système de tranport urbain trimodal.L'objectif de la régulation est double, veiller à la fluidité du trafic en général et le respect de positions réferences pour le mode bhns.L'architecture s'appuie sur la commande des systèmes en boucle fermée et utilise la commande prédictive généralisée. Nous avons proposé un modèle hybride de trafic routier basé sur le couplage d'un modèle macroscopique générique de second ordre et d'un modèle microscopique en coordonnées Lagrangiennes. Pour la validation de la bonne transmission de l'information à travers le schéma de couplage, nous avons étudié la propagation et la remontée d'une congestion. / The traffic includes several factors, including the geometry of the road infrastructure, driver behavior, the diversity of vehicle flow, etc ... The situations faced by network operators depend on the type of road network under their charge. This complexity has made traffic a research area of growing interest ever since the first studies that gave rise to the LWR model in the mid-fifties.To model the traffic on a road network, two approaches are complementary to each other are needed. The first is the flow modeling for describing the evolution of traffic flows on a stretch of road and the assignment that describes how users choose their route on a network. The purpose of this thesis work is to contribute to the improvement of the modeling of traffic flows, focusing in primarily on the modeling of a motorway traffic consists of two classes of vehicles: passenger cars and buses. The numerical study of the model is done by adapting the cell transmission model of Daganzo. An estimator for densities and speeds of the mixed traffic on a stretch of road have been submitted. Stability results in the different regimes of trafficking have been established. In the second place on the modeling of a multimodal urban traffic consists of three classes of vehicles: for the two classes mentioned above, is part a new class of high-level bus service class BRT, that tends to spread to urban and suburban which is seen as a solution to many problems related to traffic by the operators of route. We propose two models for the BRT and we develop a control strategie of this system of urban tranport trimodal (cars, buses and BRT). The purpose of the regulation of this strategy is twofold, to ensure the flow of traffic in general and respect for the positions references for the BRT mode. The architecture is based on the control of closed loop systems and uses the generalized predictive control. We have proposed a hybrid model of traffic based on the coupling of a generic second order macroscopic model and a microscopic model in Lagrangian coordinates. To validate the correct transmission of information through the coupling scheme, we have studied the spread and the rise of a congestion.

ABSTRACT The operation of urban mass rapid transit system has paid great attention on the customer degree of satisfaction, emphasizes ¡§the service oriented¡¨. This paper attempts to bracelet the traditional model, from the angle of ¡§profit oriented¡¨ discusses the urban mass rapid transit system business, and take the Kaohsiung Rapid Transit System (KRTS) as the example, draws up the related profit strategy. In the research analysis, this paper analyzes the Kaohsiung Rapid Transit System by five forces analyses to be able in the area transportation industry to compete for the profit in Kaohsiung the match and profit ability. By all the resources, the competitive advantage and the value chain analysis, establishes the Kaohsiung Rapid Transit Corp.(KRTC) core competitiveness. Moreover, by the SWOT analysis, discovers the KRTC's strengths, the weaknesses, the opportunities and the threats. Then, elaborated that this research core problems, according to the content of SWOT analysis, makes the strategy pair by the TOWS analytic method, draws up the KRTC's pursue profit strategy. The synthesis entire profit strategy, evaluated by the ¡§validity¡¨ and the ¡§feasibility¡¨, and take the ¡§feasibility¡¨ score to classify as the short, middle and long term profit strategy. According to this paper's discussion, the profit oriented KRTS divides into the short, middle and long term three broad headings of strategy. The short-term strategy according to the feasibility and the validity height, divides into three stages . The first stage is the most feasible, and the most effective strategy, should carry out immediately, altogether six items. The second stage has five items. The third stage has five items. The middle term strategy altogether has six items. The long-term strategy divides into two stages. The first stage has nine items. The second stage has three items. This paper by way of five forces analyses, in competes five forces with KRTC, its main profit competitor is ¡§the substitute threat¡¨, i.e. ¡§the motorcycle¡¨. This transport mode is the biggest profit spoliator of KRTC. Moreover, establishes the KRTC's core competitive ability from this paper, altogether eight items. At the end of this paper, we suggest that the KRTC should be at present the profit first, the proper attention to both cost, seeks government's substantive assistance, establishes a healthy financial physique, then besides the profit oriented, should give dual attention to the enterprise community responsibility gradually, then becomes a financial and the social sustainability.

The Regional Municipality of York introduced a new bus service known as VIVA in 2005. Although it has been deemed a success by many, it remains to be seen to what degree transit use was affected by its introduction. This study shows that transit ridership in York jumped substantially immediately after the implementation of VIVA. Furthermore, it is determined that the majority of new transit users in York are making home-based work or post-secondary school trips. To evaluate this, home-based work and post-secondary school generalized extreme value discrete choice models are estimated. Improvements in transit service are found to have a greater impact on transit mode share than increases in congestion for both work and post-secondary school trips. It is also, however, concluded that transit improvements played a relatively small role in the considerable shift to transit amongst post-secondary students.
