"Technical note of the NEST-USP / São Carlos"
1. The NEST-USP / São Carlos
The Traffic Safety Study Center (NEST) It is an informal group composed of professionals interested in Traffic Safety Area, which aims to promote actions and disseminate information related to the topic.
The group was formed 16 years by teachers and students linked to the Graduate Area in Transportation Engineering School of São Carlos, USP and, said, from the beginning, with the participation of teachers and students of UFSCAR, FATEC and other public and private agencies, as well as professionals.
One of the important activities of NEST has been to support the Graduate Area in EESC-USP Transport in enabling and organizing courses and lectures by experts, as well as the production and publication of books, studies, technical notes, etc.
2. Initial considerations
A comparison of the performance of road safety in cities with distinct populations is only possible with the use of accidentality or mortality rates for the population, fleet or mileage. In this technical note deaths rates are presented in 100 thousand inhabitants, in the years 2017, 2018 e 2019, in the municipalities of São Paulo over 200 thousand - where, generally, It is the largest and mortality accidentality, because in the smaller municipalities traffic conditions are different (normally, the traffic is less intense and more peaceful).
In this study the metropolitan region of São Paulo was considered as a single "municipality", since the cities that constitute it are virtually all conurbation (urban spots are unified).
The populations were obtained in IBGE site (Brazilian Institute of Geography and Statistics) and provide estimates for the years 2017, 2018 e 2019. The numbers of traffic deaths were obtained from the Respect Program site to Life (formerly called Security Paulista Moving Traffic) the State Government of São Paulo, taking into account only the municipal roads, because the management of "highways" is the State Government responsibility (state roads) or Federal (federal roads).
as there, generally, correlation between the number of accidents and the number of traffic fatalities, cities with lower mortality rate presumably are those which are also lower rates of accidentality.
4. relevant observations
No year of 2019, the five municipalities with better performance (greater traffic safety) were: Marilia (1º), Americana (2º), Big beach (3º), São Carlos (4º) and Indaiatuba (5º). The five worst performers (less traffic safety) were: Franca (22º), Saint Vincent (23º), Sao Jose do Rio Preto (24º), Araraquara (25º) and Guaruja (26º).
No year of 2018, the five municipalities with better performance (greater traffic safety) were: Bauru (1º), São Carlos (2º), Marilia (3º), Sumaré (4º) and Piracicaba (5º).

No year of 2017, the five municipalities with better performance were: Bauru (1º), São Carlos (2º), Taubaté (3º), São José dos Campos (4º) and Jacarei (5º). The five worst performers were: Indaiatuba (22º), President Prudente (23º), Franca (24º), Big beach (25º) and Sao Jose do Rio Preto (26º).
For a statistically more representative assessment of the performance of the municipalities must consider the average of the years 2019, 2018 e 2017. In this case, the five municipalities that performed better were: São Carlos (1º), Bauru (2º), Marilia (3º), Metropolitan region of Sao Paulo (4º) and Taubaté (5º). The five worst performers were: Santos (22º), Araraquara (23º), Big beach (24º), Franca (25º)and Sao Jose do Rio Preto (26º).
Between 2018 e 2019, the five boroughs that were improved in the ranking: Big beach (23 positions, 26º for 3rd), Taubaté (10 positions, from 16th to 6th, Santos (9 positions: 25º to 16º, clear river (9 positions: from 17th to 8th) and Ribeirao Preto (7 positions, 22º to 15º) Five more were worse in the ranking: Jacarei (15 positions: 6 ° to 21 °), Sao Jose do Rio Preto (13 positions: 11º to 24º), Sumaré (13 positions: 4th to 17th of), Guaruja (11 positions: 15º to 26º) and Bauru (10 positions: 1st to 11th).
Between 2017 e 2018, the five boroughs that were improved in the ranking: Sao Jose do Rio Preto (15 positions, 26º to 11º), Indaiatuba (12 positions, 22º to 10º), Piracicaba (12 positions: from 17th to 5th), Americana (12 positions, 20 ° for 8) and Marilia (7 positions: 10th to 3rd).
