New mobility in Central Areas of Smart Cities, Alexandria as an applied example

City centres are urban locations with a high concentration of economic, administrative, and cultural activities. As urbanisation continues to expand, traffic disruptions rise, adversely impacting the quality of life and the environment. In some developing countries, city centres have become overcrowded and lost their image. The paper proposes a new mobility concept for these city centres, as a primary step towards achieving smart and sustainable mobility. The new mobility aims to meet travel needs, ensure accessibility, ensure safety for all road users, and improve environmental quality. Smart mobility can then lead to an advanced transportation system with innovative technologies. Ultimately, sustainable mobility embodies a long-term vision for future generations of a cleaner, fairer, and more resilient world, without compromising the ability to meet their needs. The new mobility philosophy highlights the pivotal role of urban planners in its successful implementation. The proposed concept is applied to the Alexandria city centre as a case study, only to demonstrate its practicality as a tool for smart mobility. Therefore, two planning scenarios containing different measures are formulated and evaluated using micro-simulation and analysed with sustainable indicators. The application demonstrated that new mobility could be introduced in the traditional Alexandria city centre by 2028.
