Nowadays, city local governments focus their strategic vision on the development of the urban sustainability. For this, they develop drivers, strategies, structures on green local improvements. To be sustainable, cities reinforce actions and plans on resource management, mobility, climate, building and public spaces. In order to be sustainable and smart, challenges are set to ensure successful implementation of sustainable mobility strategies through the development of appropriate policies, actions, decisions and controls. The development of sustainable mobility strategy requires the involvement of strategic actors, infrastructures, funding and socio-demographic parameters. To ensure this, sustainable mobility strategy has to be strengthen by an efficient management control system and a real measurement of institutional factors’ risk. The development of mobility controls ensures homogeneity between behaviours, decisions, objectives and strategies for mobility issues. In order to make the link between control, strategy and sustainability, new researches propose new frameworks and systems. These frameworks reinforce the strategic contribution of values, rules, monitoring and enhancing awareness and interactions. Based on that, the management control framework of Malmi and Brown is more and more associated with the implementation of sustainable strategies. This paper explores the development of sustainable mobility strategies in two Belgian cities (Namur and Leuven). To analyse how cilty local governments implement, control and develop mobility strategies and plans, this paper refers to Malmi and Brown’s model. The research proposes two hypotheses that set the importance of the integration of an adequate sustainable mobility control system and the institutional factors on the design and the use of mobility strategy control. This paper proposes a new conceptual model to support the development of sustainable mobility strategy. For this, the choice of two Belgian cities is made according to similarities (population ...
