Table 1 Function, usage, days and types of gains across the driver support system items and additional features retrofitted onto the buses (Routine^a: drivers said that they were well assisted by the tools to follow routines; Hazard^b: drivers said that they well assisted by the tools to discover and intervene when a danger was present)
