Abstract:
One of the major challenges that state highway agencies face is the need to estimate performance curves for different functional classifications of highways and traffic loads, considering the limitations of resources and equipment required for data collection and management activities. The need to estimate the remaining useful life of pavements in different climatic regions with a variety of subgrade conditions is crucial for the efficient allocation of maintenance and rehabilitation funds. A methodology that addresses both the performance and regional climatic aspects is presented. Essential

A system dynamics model was developed for the forecasting, prioritization, and distribution of critical supplies during relief operations in case of a hurricane event, while integrating GIS information. Data was obtained from operational reports gathered during Hurricane George from agencies such as: Puerto Rico Department of Housing (PRDOH), Puerto Rico National Guard (PRNG), Civil Defense State Agency of Puerto Rico, Puerto Rico Department of Transportation and Public Works (PRDOTPW) and Puerto Rico Highway & Transportation Authority (PRHTA), along with reports from other U.S. agencies.

Abstract:
The road diet concept has been implemented around the United States for more than three decades. Road diets are at the early stages of implementation in Puerto Rico and the use of a Two-Way Left Turn Lane (TWLTL) will be a new and unfamiliar design for local drivers. For this reason, the effectiveness of a TWLTL was evaluated using a driving simulator with local drivers for a segment of highway PR-107 in Puerto Rico. This highway is a suburban commercial corridor without access control that had a 67% increase in crashes between 2015 and 2016. This highway was selected because of its large numb

Puerto Rico is an uncomfortable reminder of the democratic deficits within the world’s oldest constitutional democracy. Puerto Ricans are U.S. citizens who live in a U.S. territory that is subject to the plenary authority of Congress, to which they cannot elect voting members. In 2022, under unified Democratic control for the first time in a decade, Congress considered the Puerto Rico Status Act, legislation that would finally decolonize Puerto Rico. The Status Act offered Puerto Rican voters three alternatives to the colonial status quo—statehood, independence, or sovereignty in free associat

ABSTRACT: Read as a diagnosis of the ills afflicting colonial Puerto Rico, Manuel Zeno Gandía's novel La charca is often critiqued as paradigmatically expressing the racist, paternalistic worldview of the author and the creole elite. This, however, only pertains when one equates the novel's narrator with its author and presumes the former's omniscience. Recalling how the novel exposes the failures of characters of authority and repute—from colonial state representatives to the creole elite—I contend that the narrator, as one such figure, also fails, in his attempt to diagnose and cure (through
