The urban insertion of public transport refers here to managing the interface between this means of transport and other uses of the public space where they are running. It deals with optimizing the system to make it as efficient as possible, while guaranteeing a greater safety for all users. This relates back to road design, traffic management, traffic regulation and signage, which are nseparable topics. Although it takes on its full meaning for tramways and buses with a high level of service, this notion also applies to standard bus lines and suburban public transport systems. Regarding guided transport systems, Certu works in close cooperation with STRMTG, the relevant state agency for their safety.
