Abstract
This paper aims to examine road fatalities using a GIS approach in Trinidad in an effort to provide recommendations on how road collisions and the number of casualties can be mitigated. In order to achieve this, the paper has examined a number of maps of Trinidad. The study examined data generated from maps of Trinidad using the Arc GIS Maps 10 software. Different variables were used to manipulate the data and these were road incidents by administrative area, municipalities, population density and socio economic status in Trinidad. The data generated represented the period 2005 to 2011 from 355 locations across Trinidad. From the data analyzed, it is clear that there is a positive correlation between the number of fatalities and the economic status of an area as well as the population of the area. From the data represented in the maps, it is clear that in regions with high population and numerous intersections such as City of San Fernando, Tunapuna, Port of Spain, San Juan, Laventille, and Diego Martin the number of road fatalities was high. The findings established in the study can allow for change in: (i) Road Traffic legislation and control measures and (ii) infrastructural redesign and implements. Key words: Geographic information system, Trinidad, road traffic fatalities.
