Looking at road safety data, what appears to be necessary today is:
- to make data more reliable;
- to make data as complete as possible, in particular from the point of view of the variables found;
- to ensure that the data is more rapidly available, both for the monitoring of the phenomenon and the evaluation of the prevention actions;
- to introduce statistical analyses aimed at existing databases and more “suitable” for today’s needs.
Unfortunately, in many cases the above-mentioned needs are routinely disregarded in practice. There are various reasons for this, ranging from the inadequacy linked to the “construction” of the elementary statistical data to those more specifically of an organisational type.
The DaCoTA database is supported by a web application (rich internet application) for in-depth investigations which allows the collection of over 1,500 different variables for each accident.
The project was developed by means of the design of a system that addresses the specific needs of in-depth investigations on road accidents, integrating new variables or new items for specific variables, so as to permit as complete as possible a data collection for road safety research purposes.
