Validating crash locations for quantitative spatial analysis
This paper describes a GIS-based methodology of the spatiotemporal analysis of this phenomenon.
Thus, for a given study area, in this case of Milos Island, Greece, the geometry of the road network, the terrain morphology and the solar radiation (in specific time intervals during summer) have been analyzed.
So hardware, software and databases are combined towards the extraction of new knowledge.
They give the possibility to have fast results throughout the process, which extends from the data management to the analysis and the visualization of them .

*Prices in US$ apply to orders placed in the Americas only.
Prices in GBP apply to orders placed in Great Britain only.
The result of this procedure is a map illustrating the sections of the road where direct sunlight includes a serious amount of risk for the drivers.
Applying this methodology for long periods of time may lead to prevention policies adoption related to accidents of direct exposure to sunlight.
