Methodological Framework for Defining the Sustainability Management Process for Urban Mobility Systems Based on System Engineering

Abstract

Current urban mobility trends go beyond infrastructure investments and integrating new technologies, reflecting new user requirements and regulations, and the increasingly rigorous and sustainable governance. Designing an urban mobility system and assessing its sustainability require a flexible holistic approach considering the complete life cycle of the system and interdependencies between its components. This paper proposes a novel methodological framework based on system engineering tools, aimed at helping public authorities designing and deploying new urban projects, accounting for the entire life cycle of the mobility system, evolving requirements of users, and sustainability. The main goal is to validate the proposed framework by simulations. A realistic case study employing the new framework showed its advantages, consisting of solving problems in a manner comparable to other methodologies, but adding flexibility in managing different data inaccessible to urban managers before allowing for defining effective urban mobility policies.

Cyber-Physical Urban Mobility Systems

“…Urban mobility must consider alternatives to private vehicle in order to reduce the pressure of motorized traffic on roads and the environment. However, (Ngossaha et al, 2020;Moskolaï et al, 2019) classified the approaches to the urban mobility systems design into two categories, (1) approach by sectoral analysis, and (2) global system-oriented approach. For authors, approach (1) does not bring visibility into the entire system, but rather creates conflict between the subsystems that can affect the efficiency of the mobility system.…”

“…Interactions are not very representative of the whole system, and its representation is ill-suited to understanding it. (Ngossaha et al, 2020) proposed a holistic approach considering the entire lifecycle of sustainable urban mobility system. Ngossaha et al have subdivided the system into four subsystems: (i) the topology of the urban mobility system; (ii) the timetables of the urban mobility system; (iii) the urban mobility services; and (iv) the management of the urban occupation of mobility.…”

“…The authors (Ngossaha et al, 2020) contributed significantly to sustainable urban mobility to preserve the environment for future generations in the context of developing countries. For the authors, the new mobility should enable the reduction of air pollution, collaboration between actors and integration of mobility services.…”
