Transportation systems are integral to modern societies’ functioning, facilitating people’s movement to complete their daily tasks, such as going to work and school, as well as delivering goods to meet people’s diverse needs. However, the escalating transportation demands resulting from the rapid urbanization and the boom of E¬commerce have exac erbated traffic congestion and given rise to environmental issues. Consequently, actions must be taken to mitigate the negative externalities of growing transportation demands. In 2007, the “Green Paper: Towards a New Culture for Urban Mobility” presented by the European Commission advocated for better integration of passenger and goods trans port in urban planning. It emphasized that “Local authorities need to consider all urban logistics related to passenger and freight transport together as a single logistics system.” The integration of passenger and goods transport offers a multitude of advantages. First, it could reduce traffic congestion and environmental pollution by reducing the number of used vehicles on the road and the total vehicle kilometers traveled. This is achieved by optimizing the routes of passenger and freight vehicles to curtail the overlap between them. Second, this integration could enhance cost¬effectiveness and boost the economy by efficiently utilizing transportation resources (e.g., roads and vehicles), reducing oper ational expenses for businesses and improving mobility for people and goods. This, in turn, increases trade and economic activity. Third, the integrated transportation system improves the equity and accessibility to transport services, particularly in rural areas, as merging logistics services with public transport makes the transportation service more viable, ultimately reducing the isolation experienced by rural residents. This thesis comprises four papers and makes several contributions to the realm of in tegrated people and goods transportation. It provides an overview of the development of integrated transportation systems, introduces two novel forms to integrate passengers and goods, validates their viability, and advances mathematical optimization within this field.
