This document summarizes the historical and technological advancements in transportation networks, from the development of canals, roads, and rail networks to modern innovations in air, sea, and urban transport.

[...] Towards a global connectivity In addition, the future of transportation lies in the greatest intermodality, namely the combination of several modes to facilitate the transport of goods and passengers. This includes combined river and land transport, where boats are used for short distances and trucks for the last kilometers. This reduces both the costs and the negative impacts of logistics operations and is particularly relevant in cases of overloading of railway and road transporters. Another shift underway concerns the geographical redefinition of global flows, as highlighted by the emergence of a greater number of hubs, particularly in Asia-Pacific. [...]
[...] This change can be interpreted as a shift of the global economic center of gravity towards Asia and the Middle East, and this requires different approaches for global connectivity from European and American actors. However, the future of transportation is not just about technology; it involves creating integrated, sustainable, accessible, and inclusive systems that will meet the evolving needs of a global population. Ensuring a sustainable mobility that takes into account both the need for progress, environmental protection, and equity is essential to building a resilient and harmonious future. Ultimately, transportation remains the crossroads of the world that is constantly turning and changing. [...]
[...] The Challenges of Saturation and Adaptation Air Network and Hub-and-Spoke Model The hub-and-spoke model is centered on major airports where passengers are routed, then dispersed for subsequent flights. This system allows for better coordination of flight schedules, but also leads to overloading of main hubs and, consequently, the need for significant investments in infrastructure. Furthermore, the emergence of new low-cost airlines using small airports reduces the load to some extent and offers an alternative to greater deactivation. Maritime Route Congestion and Port Overcrowding Port complexes are also increasingly saturated. [...]
[...] Technological Evolutions in the 20th Century The Rise of Air Transport (Jet Airliners, Jumbo Jets) During the second half of the century, this mode of transport experienced an extraordinary growth. Firstly, with the introduction of the first Boeing 707 jets in the early 1950s, passengers could fly at higher speeds and over a greater distance. Then, in the 1970s, with the introduction of jumbo jets, the first Boeing 747, aviation was finally democratized, as air transport became cheaper due to the economies of scale possible. In other words, air transport was 'demedicalized'. [...]
[...] Although most geographical and technical constraints have been overcome thanks to technological progress and innovation, new challenges have also emerged: environmental impact, accessibility inequalities, congestion, mobility has become a development, spatial justice, and sustainability issue. These new forms of regulation and decentralization of mobility organization are being studied to understand the mutations of transportation networks over time. We will therefore address three major themes: 1. The historical and technological mutations of transportation networks. 2. The current challenges of transportation systems in the face of sustainability and accessibility challenges. [...]
