LUNA GONZALEZ, Laura  and  CHIAS BECERRIL, Luis. El uso de SIG en el análisis de la distribución de accidentes en carreteras: el caso de Tamaulipas, México. Invest. Geog [online]. 1999, n.40, pp.148-162. ISSN 2448-7279.

In this paper, the distribution of traffic accidents in federal highways of Tamaulipas State during 1992 is anaiized using a geographical information system (GIS). The use of Arc/Info is proposed and, specifically, the set of programs known as Dynamic Segmentation, that allow the management of different databases about the fenomena studied and stablishing virtual access links between both databases and digital map. A set of statistical databases of these events (pavement quality, highway signal and infraestructure data) was used for testing the operation of Dynamic Segmentation in traffic accident analysis.

Keywords : Traffic accident; geographic information system (GIS); dynamic segmentation; spatial analysis.
