Alto Tietê Traffic Deaths Drop 3.7% in 2025

The Alto Tietê region witnessed a modest but significant improvement in road safety during 2025. According to comprehensive data analysis, traffic fatalities dropped by 3.7% compared to the previous year.

This decline represents a shift in regional safety trends, bringing the total number of lives lost to 182. While the reduction is welcome, the data reveals persistent patterns regarding who is most at risk and when these tragedies occur.

The statistics paint a stark picture of the demographics most affected by traffic violence. The data indicates a severe gender disparity in fatal outcomes.

Of the 182 individuals who lost their lives, 162 were men. This figure represents a staggering 89% of all recorded fatalities. In contrast, women accounted for the remaining 32 deaths.

This overwhelming majority suggests that specific behavioral factors or exposure risks may disproportionately affect male drivers and pedestrians in the region.

Timing plays a critical role in the likelihood of a fatal collision. The data highlights specific windows of time when the roads become most dangerous.

Nearly half of all fatalities—48.9%—occurred during the night and early morning hours. This period accounted for 89 deaths. The afternoon hours followed as the second most dangerous window, resulting in 52 fatalities.

Geographically, the majority of incidents took place on municipal roads, which saw 98 deaths. State roads were the second most common location for fatal accidents, recording 67 incidents.

Key Risk Periods:

• Night and early morning (48.9% of fatalities)
• Afternoon hours (28.5% of fatalities)
• Morning hours (19.2% of fatalities)

Motorcycles emerged as the most lethal vehicle type on the roads. Data shows that 82 victims were riding motorcycles at the time of their deaths, accounting for 45% of the total.

Cars were the second most common vehicle involved, linked to 36 fatalities. Bicycles were involved in 15 deaths.

Regarding the nature of these incidents, collisions were the leading cause of death, comprising 37.9% of all accidents. Atropelamentos (pedestrian strikes) were the second most frequent type of accident, responsible for 45 deaths.

The data also clarifies the role of the victims: 114 individuals were operating vehicles when killed, while 42 were pedestrians.

Among the ten municipalities comprising the Alto Tietê region, one city consistently recorded the highest number of tragedies.

Mogi das Cruzes registered the most fatalities in both 2024 and 2025. While the number dropped slightly from 58 to 55 deaths, it remains the most impacted area in the region.

This concentration of incidents suggests that specific local infrastructure or traffic volume in Mogi das Cruzes requires continued attention to improve overall safety for residents.

The 2025 data from the Alto Tietê region offers a detailed look at traffic safety trends. While the overall reduction in deaths is a positive development, the statistics highlight specific vulnerabilities that require targeted interventions.

Summary of Findings:

• Overall Trend: A 3.7% decrease in fatalities year-over-year.
• Demographics: Men are disproportionately affected, representing nearly 9 out of 10 victims.
• Vehicle Risk: Motorcycle riders face the highest risk of fatal injury.
• Timing: The majority of accidents occur during low-light conditions (night and early morning).

Addressing these specific factors—particularly motorcycle safety and night-time driving—will be crucial for sustaining and improving road safety in the coming years.
