The entire shared taxi network covered some 8-10 city blocks of downtown Ponce. This decentralized system changed in 1990 when all these líneas scattered throughout downtown Ponce were centralized at the 3-story high Terminal de Carros Públicos Carlos GarayPorta Caribe: Ponce and around.

Yet, while the 1990 públicos centralization at the Carlos Garay Terminal building relieved congestion in some downtown streets, it did little to provide relief from other públicos-related problems: the system continued to be plagued by unpredictable and sporadic service, limited or no service on weekends, no evening service, and similar weaknesses.

In 2008, the administration of mayor Maria Melendez, commissioned a study to seek a solution to these problems. After the necessary studies and permit phases were completed, the bus-based mass transit system known as SITRAS was launched.Estudio de Transportación. A. M. Figueroa.

Unlike the shared taxi system, SITRAS provides predictable, scheduled service as well as weekend and evening service.Nuevo Sistema de Transporte en Ponce: Guaguas recorreran 26 comunidades de la Perla del Sur. Sandra Caquías Cruz. El Nuevo Dia. San Juan, Puerto Rico. 15 February 2012. Page 34. Retrieved 5 July 2012. However, the advent of SITRAS did not do away with the use of públicos altogether. Instead SITRAS was designed to complement the shared taxi service, with SITRAS taking over several city proper routes while públicos were expected to provide "connections" along the SITRAS routes to more remote and rural areas where SITRAS buses could not reach.Estudio de Transportación.
