International audience ; As a result of half a century of transformations due to successive urban policies, Algiers today is a spread, fragmented and disjointed agglomeration. It also faces real challenges in terms of planning of transport and mobility. The automobile dependency status is reflected by the fact that it has become essential for daily movements for a large part of the population. The organization and efficiency of the transport system and urban form directly influences the mode of transport favored by the population. Our article proposes to compare the performance of private automotive system and public transport in terms of accessibility. Through the establishment of a GIS database and a comparative approach, the result of this work allowed us to better understand the space-time dimension in Algiers and the evolution of accessibility, that have happened to the various agglomerations between 2004 and 2015. Indeed, this approach has never been the subject of a deep analysis in the various researches on the city of Algiers. An accessibility modeling appears to be a very interesting approach, firstly to have a clear vision of "accessibility", one of the decisive parameters of any transport policy and also to better appreciate the consequences of the various public transport policies. ; Après un demi-siècle de transformations urbaines (conséquences de politiques urbaines successives), Alger d'aujourd'hui est une agglomération étalée, éclatée, fragmentée et discontinue. Elle est également confrontée à de véritables enjeux en matière de planification des transports et de la mobilité.Le concept de dépendance à l'automobile reflète le fait que cette dernière soit devenue indispensable pour l'ensemble des déplacements quotidiens d'une majeure partie de la population. L'organisation et l'efficacité du système des transports et la forme urbaine influencent directement le mode de transport privilégié par la population. Notre article se propose de comparer la performance du système automobile et du transport en commun sous l'angle de l'accessibilité.À travers la mise en place d'une base de données sous SIG et par une approche comparative, le résultat de ce travail nous a permis une meilleure lecture de la dimension espace- temps à Alger ainsi que l'évolution de l'accessibilité qu'ont subie les différentes agglomérations entre 2004 et 2015.En effet, cette approche n'a jamais fait l'objet d'une analyse profonde dans le cadre des différentes recherches sur la ville d'Alger.

[EN] Algerians citizens most often travel by foot on their daily trips because the lack of a homogeneous offer of public transit and intermodality throughout the city. Furthermore, the private vehicle is experiencing a notable increased use over the last few years. To curb this tendency, the government has launched a metro and a tramway system as key parts of a whole sustainable transport strategy. Guaranteeing the profitability of these modes of transport demands a high quality operation level focused on the users' needs and requirements. While numerous studies have been carried out in developed countries for identifying the essential aspects of different transit modes, this area is still new in developing countries. Then, this paper aims to identify the key quality factors of the railway transit services in Algiers for advising transit authorities and managers towards the most appropriate policy measures. The railway transit services in Algiers consist on three modes of transport: the metro, the tramway (both started into operation in 2011), and a commuter rail system. A Principal Component Analysis combined with a regression model integrates the assessment approach. The results of this research highlight differences among the transit systems analyzed and provide useful insights for the Algiers government and transit authorities. ; Oña, RD.; Machado, JL.; Baouni, T.; Oña, JD.

The improvement in public transit is one of the basic and essential pillars to promote sustainable urban and metropolitan mobility everywhere. Algeria´s transportation system primarily relies on private vehicle, which causes innumerable problems such as congestion, emissions, traffic accidents, social inequalities, gender inequalities, and deterioration of the environment. Given that, the Algerian Government has recently carried out some transportation projects such as the Algiers metro and tramway service to promote collective public transportation in the country. Therefore, it becomes essential to provide public administrations and technicians with relevant information and efficient analytical tools to help enhance and develop this mass transit. In this line, the first Customer Satisfaction Survey was designed and implemented in November 2014 at the three railways transit services of Algiers: the light rail, the underground heavy rail (both started into operation in 2011) and the commuter rail. Thanks to this survey instrument, users' profiles and travel patterns were found out. Moreover, an analytical framework based on a principal component analysis and an ordered probit model identified service quality dimensions and their impact on users' overall satisfaction. In addition, the effect of socio-economic variables and travel patterns on the previously identified quality dimensions was obtained through multiple linear regression models. The results presented in this paper could help Algerian transport authorities towards elaborate specific proposals to increase transit ridership. ; The improvement in public transit is one of the basic and essential pillars to promote sustainable urban and metropolitan mobility everywhere.

Fast population growth, urban sprawl and the raise in households' motorization observed in all major cities of the Middle-East and North-Africa (MENA) region, are constantly challenging public transport providers who seek to handle efficiently the continuously rising travel demand. Most of the MENA cities suffer from traffic congestion that not only impacts the quality of life of MENA citizens, but also their access to job opportunities, health services, and social and political participation. Alongside the development of public transport network, it is crucial to encourage urban dwellers to reduce their dependence on personal cars, use public transport, and develop soft mobility skills. Therefore, operators and service providers need to define customer-centric strategy and build a culture of service excellence in line with their customers' expectations. In cooperation with academic partners, the UITP MENA Centre for Transport Excellence launched the User-Oriented Public Transport research project with the aim to understand the perceptions of female and male users and non-users about public transport services in five MENA cities: Algiers, Amman, Beirut, Casablanca and Muscat. The methodological framework was built around the five dimensions of the user's needs pyramid: safety, security, ease-to-use, comfort and experience. Based on the quantitative analysis of data collected from 984 respondents and the qualitative analysis of 49 women's testimonies collected during the focus groups, recommendations were made to encourage culture of service and gender mainstreaming in public transport development in the region. ; Fast population growth, urban sprawl and the raise in households' motorization observed in all major cities of the Middle-East and North-Africa (MENA) region, are constantly challenging public transport providers who seek to handle efficiently the continuously rising travel demand.
