This article highlights the need to rethink how to manage mobility in Morocco more intelligently, given that it is a major pillar of economic competitiveness. Smart mobility based on Intelligent Transport Systems (ITS) allows to improve and ensure the optimal use of existing infrastructure before embarking on heavy and irreversible infrastructure projects. The case regarding the separation of the urban traffic and the Heavy Goods Vehicles (HGV) traffic circulating between Casablanca Port and Zenata Dry Port is a relevant example where smart mobility could provide efficient solutions without building costly tunnels. A dynamic simulation was made using the Aimsun software to quantify the relevance of the proposed lane designated to HGV in the existing road. This simulation allows to visualise congestion sections and quantify the circulation of vehicles and pedestrians. The article presents defined functions and characteristics of the Advanced Traffic Management (ATM) to ensure the optimal operation and efficient setting of the simulation. All appliances, hardware, and sensors that will be set up on-site will help to improve traffic safety, traffic flow, traffic information, and reduce congestion and pollution. This case study illustrates the complexity of managing the flow of goods in cities and suggests how to solve this type of problems using smart mobility. This research proposes reserving a special lane for HGV. ITS will help this cost-optimal alternative, will promote the urban framework of the coastal road, and contribute to sustainable mobility in Casablanca.

To be sustainable, mobility must be smart, safe, fair, and take into account the harmful effects on the environment. It must improve the quality of citizen’s life by safeguarding human health and natural ecosystems. This sustainable mobility must optimize resource consumption and public spaces, facilitate accessibility, promote economic dynamism, commit to the social responsibility of individuals, companies, and society, and respect environmental integrity [1]. Thus, sustainable mobility contributes to development and responds to the travel demands of present generations without compromising the ability of future generations to meet their own needs [2]. All modes of transport emitted in Morocco in 2014: 16 million tons of CO2 equivalent representing 19.2% of the country's total emissions. Morocco has set itself a target of 42% for reducing GHG emissions from the year 2030 [3]. This article presents the results of research conducted for the setting up of a new model of sustainable mobility - in a horizon of 20 years – in an urban Moroccan area, booming 'Fez'. It offers a conceptual approach to measuring the sustainability of the transport system. An analysis of the supply and the need for trips in a reference situation first allows for formalizing realistic objectives. Then, a sustainable mobility model is developed to prevent social and environmental costs from being higher than the services provided by the transport systems of this city. Finally, a comparison between the trend situation and the corrected situation with this sustainable mobility model allows us to appreciate its contribution.
