Resumo(s)
Over the last fifty years mobility practices have changed dramatically, improving the way travel takes
place, the time it takes but also on matters like road safety and prevention. High mortality caused by high
accident levels has reached untenable levels. But the research into road mortality stayed limited to comparative
statistical exercises which go no further than defining accident types.
In terms of sharing information and mapping accidents, little progress has been mad, aside from the normal
publication of figures, either through simplistic tables or web pages. With considerable technological advances on
geographical information technologies, research and development stayed rather static with only a few good
examples on dynamic mapping. The use of Global Positioning System (GPS) devices as normal equipments on
automobile industry resulted in a more dynamic mobility patterns but also with higher degrees of uncertainty on
road traffic. This paper describes a road accident georeferencing project for the Lisbon District involving fatalities
and serious injuries during 2007. In the initial phase, individual information summaries were compiled giving
information on accidents and its majour characteristics, collected by the security forces: the Public Safety Police
Force (Polícia de Segurança Pública - PSP) and the National Guard (Guarda Nacional Republicana - GNR). The
Google Earth platform was used to georeference the information in order to inform the public and the authorities
of the accident locations, the nature of the location, and the causes and consequences of the accidents. This
paper also gives future insights about augmented reality technologies, considered crucial to advances to road
safety and prevention studies.
At the end, this exercise could be considered a success because of numerous consequences, as for
stakeholders who decide what to do but also for the public awareness to the problem of road mortality.
