In Brazil, the road modal is the one that has the largest share in the transport matrix. The focus of this research was on Bonaire street, in the municipality of Açailândia-MA, as it has a connection with the bus station and the central zone of ??the municipality in question. The quality status of the work presented was to classify the quality status of a section of this street, through the selection of parameters of longitudinal irregularity through a practical, modern and efficient methodology, using a MERLIN equipment modified with a tremendous laser. Defined duration data were analyzed according to a defined duration methodology, or through a frequency graph, where data were defined according to stretch depreciation or stretch length. For this, measurements were carried out in a 200-meter stretch with the LIN modifier, calculating the parameters of: International Roughness Index (IRI) and Irregularity Quotient (QI) of these analyzed stretches. It is determined with this work that the concept of Bonaire street condition is terrible and that as the most practical and efficient data collection process, it has become the most practical and efficient traditional data collection process, and thus the process of traditional IRI QI data collection. Finally, through these various initiatives are created for future research on conditions mainly due to the work on the technical leap that approaches the MERLIN process studied, thought in this traditional work.
