Madrid’s metropolitan area has a population of about six million people, with most of them located in the center of the city. To help mobilize residents and visitors, the city maintains a metro, an urban bus network, an extensive network of high-capacity freeways, interurban buses, and railway services. To ensure effective service delivery, the city needed a way to better integrate the different transportation modes, urban and metropolitan. This led to the introduction of a transportation exchanger. Transportation exchangers are intermodal nodes of urban and interurban transport networks that facilitate the integration of different transportation types and minimize the inconvenience to travelers of transfers during transport. They are equipped with air-conditioning, commercial areas, and other facilities that make travelers more comfortable. This type of infrastructure provides an optimal mode of transfer from regional and inter-regional buses or railway services to metro networks and urban buses.
