Ces mémoires constituent un travail à visée pédagogique dans le cadre d’un diplôme universitaire et ne constituent en aucun cas une étude susceptible d’être ré-utilisée dans un cadre commercial ou scientifique. Son contenu n’engage que la responsabilité de ses auteurs.Dans le cadre du Mastère Spécialisé « Systèmes de Transports Ferroviaires et Urbains » de l'École des Ponts ParisTech, les étudiants réalisent un projet de transport dans une ville étrangère. Il s’agit d’une étude de faisabilité, similaire aux études amont en phase d’émergence, que réalisent les grands bureaux d’études comme Systra ou Parsons. Ce travail collaboratif, faisant jouer les complémentarités des savoir-faire, prend la forme d’un mini-mémoire.Les résumés de ces mini-mémoires sont regroupés dans un « Urban and Railway transport studies Yearbook », réalisé par la Direction de la Documentation de l'École des Ponts ParisTech en collaboratoire avec Françoise Manderscheid, responsable du Mastère Spécialisé.The agreement signed on July 14th 2015 is a historical event for Iran, allowing the country to join the international community after the end of penalties. Iran is indeed a promising country with a potential market of 80 million people and a well‐ educated middle-class. President Rohani has even stated that the government’s priority is the country’s economic recovery of. The program unlocking Iranian assets and reopening borders for international trade should thus encourage foreign direct investment, increasing trade and stimulating growth. Sanctions relief increase public expectations of economic improvement and international commitment. The transport field has been neglected for years, in favor of industrial fields such as oil and gas, metals and minerals. The city of Qom has been particularly suffering from alarming problems of pollution, congestion and high road accidents, whereas public transport field is still very limited. Monorail and metro projects have already been launched, but they are still under construction. Our project starts with a diagnosis at a national scale to describe geographic, environmental, institutional, economic and socio‐demographic aspects. Then, we focus on specifics of the city of Qom in order to better understand the local expectations. After making an assessment of transportation modes in Qom, we will analyze the mobility in the city to decide if we need to develop a third urban transport system. This will lead us to identify two main corridors in the city, carriers of flows, allowing us to draw a horizontal alignment for this public transportation line. Afterwards, a study of the transport demand on this axis will help us choose the relevant means of transport. A proposal for a complete tramway system will be given, including a technical feasibility study for Infrastructure and Rolling Stock structural subsystems and an operational feasibility study for Operations and Maintenance functional subsystems. Finally, an economic feasibility study will be submitted, taking into account cost and revenue aspects to assess the socio‐economic and financial profitability of such a project. Lastly we will propose project funding options and conditions necessary to support the launch of the project with regard to redirecting transport policy, in order to make it financially viable
