FUENTES F., César M.  and  HERNANDEZ H., Vladimir. Urban Spatial Structure and Frequency of Traffic Accidents in Tijuana, Baja California (2003-2004). Frontera norte [online]. 2009, vol.21, n.42, pp.109-138. ISSN 2594-0260.

His article analyzes the impact of urban spatial structure (traffic flows, land-use mix, and socioeconomic characteristics) on the frequency of traffic accidents in Tijuana, especially those classified as car crashes. We used a spatial-analysis methodology, and we estimated a negative binomial regression model. The accident database was taken at the census-tract level, based on information from Tijuana's Dirección de Seguridad Pública (Public Safety Office), the Population Census (INEGI, 2000) and the Economic Census (INEGI, 2004). Findings showed that the proxy variables for traffic flows, land use by businesses and services, and the proportion of population with incomes higher than five minimum wages are statistically significant in explaining a higher frequency of traffic accidents. In contrast, variables like population density and industrial land use are statistically significant for a lower frequency of car crashes. These findings could help to design public policies aimed at reducing the number of traffic accidents.

Keywords : Traffic accidents; urban spatial structure; land use; negative binomial model; Tijuana.
