    The TARVA safety evaluation tool has been created for reliable evaluation of the current safety situation and the safety effects of improvements. Separate versions of TARVA have been created for the Lithuanian and Finnish roads and Finnish level crossings. Using TARVA, one can also reliably rank the existing network by its safety. Safety ranking is based on expected accident numbers achieved by combining accident history data with accident prediction model data. In addition to comparing the safety of individual roads, an example is presented on comparing the road safety of different areas using the simple accident prediction models prepared for TARVA. Initial results from the comparisons suggest that quite a lot can be learned about safety potential by comparing the safety of different areas and of individual roads using available science-based analysis tools
