Introduction:

environmental pollution in urban areas is mainly due to greenhouse gas emissions from the burning of fuel in the vehicle fleet, which increases in situations of vehicle congestion, which, in addition to being a source of noise pollution, affects the physical and mental health of citizens.

Objective:

to determine the perception of independent urban transport consultant experts on the causes of vehicle congestion and its relationship with environmental pollution and health.

Materials and methods:

an observational and descriptive study in the city of metropolitan Lima, through the identification of critical points of vehicular congestion and through structured interviews with independent consultants, on the causes of traffic, environmental pollution and health.

Results:

the main traffic generators observed were constructions, closed streets, ambulatory commerce, informal stops, unauthorized parking, and accidents. While the causes of congestion, identified by the consultants, were based on poor management and road planning, lack of road safety education for drivers and pedestrians, informal stops, and obsolete vehicles.

Conclusions:

the capital city still suffers from high levels of traffic congestion, which affects the health and economy of Peruvians. From the analysis based on the opinions of experts, it is recommended that strategies and policies be directed towards solutions that include institutional reforms that favor improvements in efficiency and effectiveness in the management of urban transportation, facilitate the renewal of the vehicle fleet and implement awareness campaigns to create a citizen culture.
