Traffic mortality in Paulistas Municipalities with more than 200 thousand

"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.
