“The road” is anthropologically linked to the history of the human being, and therefore also to the economic history. Specifically, “the road” is important quantitative element as a factor in the opportunity cost in the traffic of goods, commodities and people but also, on a more abstract level, important qualitative element: better or worse traffic impacts on the substantive and practical transport trucks, on carried goods and on driving workers._x000d_ We want to relate this study with a qualitative element of the carrier, in this case waste, such as the quality of this work to a quantitative element, i.e. the urban surface, the distance traveled, the density and the degree of traffic of a municipality. This study would examine whether there is an economical semantic relevance between what and how the path is and, once the possibility and feasibility of significance is established, it would want to test the kind of semantic rank, if space and quality of work have a significant correlation and how much it is significant. This work is focused on the garbage truck drivers and the link between waste collection path and drivers’ task. The last step will be to verify whether this semantic space-quality of work in the waste industry has the same significance if we consider a different carried on object with other typologies of drivers: public transport drivers, couriers, taxi drivers._x000d_ This study would focus on the variables that can affect the propensity of accidents of the drivers in bus and refuse sector: geographical and territorial, social and personal (like density of population, density of vehicles, knowledge degree or expertise). First of all, how much is significant the length of the path, i.e. how much the urban streets involve the risk of accident. Moreover, how much the technological innovation could contribute to decrease the frequency and the size of accidents for garbage truck drivers. Finally, how much the personal characteristics and behaviours could affect kilometres-accident risk relationship.
