Traffic engineering is essential for any city that wants to maintain good traffic flow on
its access roads, as its focus is on planning, organizing and managing the flow of
vehicles and pedestrians in a safe and efficient manner. However, there are many
problems to be solved in the city of Belém, such as access to Gate 1 of the Guamá
University Campus. Therefore, the general objective of the study is to propose traffic
engineering measures to improve flow and safety at the intersection of Avenida
Bernardo Sayão and Rua Augusto Corrêa, through physical separation of traffic
directions and the installation of a return device, such as a roundabout, on Rua
Augusto Corrêa. This proposal seeks to reduce the points of traffic conflict, ensure
the implementation of appropriate signage and, in addition, the study considers the
impact of Traffic Generating Hubs (PGTs) on the site, since these areas increase the
volume of vehicles and influence the safety and quality of traffic in the surrounding
area. To do this, the following methods were used: traffic counting; vehicle
classification through image recording; and evaluation of the intervention geometry.
This stage took place during the three main peak hours of a regular academic day at
UFPA, lasting one hour in each period. The data indicated that the proposed physical
separation and roundabout would reduce conflict points, with the road geometry
accommodating critical vehicles.. The analysis showed that these interventions would
meet safety demands and improve mobility, benefiting the safety of both pedestrians
and drivers. It is concluded that the suggested interventions are effective and
potentially advantageous for traffic organization and safety in the studied area,
demonstrating that the proposals contribute to more efficient and safer traffic
management.
