For a calculated BTSL, according to form (9), traffic safety scale would be:
Example of BTSL calculation for Beograd: according to proposed BTSL method calculation process is as follows: Annual number of traffic accidents fatalities per 100000000 vehicle kilometers (DTR) is 5, that means the transformed value of the indicator is 0.
Considering the values of BTSL it is possible to rank the selected cities (column 'rank' in Table 7), and it is also possible to define a state of traffic safety in the selected cities (column 'state of BTSL').
Therefore, using the BTSL method points to the conclusion that only the cities of Belgrade and Ljubljana are medium safe, and all the rest of the cities have a low degree of traffic safety.
The results obtained through the implementation of BTSL method for the rating of traffic safety levels, facilitate the rating of traffic safety levels but also the comparison and monitoring of traffic safety levels in different territories, as well as tracking the effects of implemented measures.
In BTSL method we have proposed six indicators that fulfill necessary condition of availability and data quality.
One of the benefits of BTSL method is defining the level of traffic safety level of particular territory, which by using proposed scale, defines whether territory is very highly safe, highly safe, medium safe, low safe or very low safe territory.
Reliability of proposed method has been tested through example of Sweden, compared to already examined cities and it is shown that proposed BTSL method give good results of road safety level.
