Pavement Condition Index (PCI) Data for 5,271 Urban Roads in León, Guanajuato, Mexico
Description
The database consists of 5,271 urban roads evaluated in the City of Léon, Guanajuato, Mexico; it was proportionate by the General Directorate of Public Works of the Municipality of León. This sample includes roads with low, medium, and high traffic levels. The evaluation consisted of determining the type, quantity, and severity of each failure found, following the criteria defined by the Pavement Condition Index (PCI) method established by the United States Corps of Engineers. Seventeen types of damage were analyzed out of the 19 considered by the original method. The reason why only 17 damages were evaluated is that the “Crossing Railroad” is not in charge of the government of Mexico but instead of companies that have a concession for said infrastructure; likewise, the “Freezing” has not been carried out either evaluated, because the minimum temperatures do not reach a level of freezing. The original PCI method requires obtaining each damage and its severity level, which is measured at three different levels: light, moderate, and severe. Once the data is obtained, the PCI is calculated. For our case, it was decided to add the densities or percentages of the three levels of severity for each damage so that a single percentage of total damage is obtained for each type of failure. However, it should be noted that the PCI was calculated according to the original methodology, considering the three levels of severity corresponding to each type of damage found. Therefore, the database presented considers 17 damages with a single level of severity, which was determined as the sum of the densities of the three levels considered by the original method; likewise, the PCI shown in the database also corresponds to that calculated with the original method, considering the three levels of severity.
