Diseño de solución vial para complejos portuarios con las avenidas principales del sur de Guayaquil

Abstract

CONDITIONING OF PROJECT PUBLICATION. The port sector of Isla Trinitaria in Guayaquil faces severe vehicular congestion due to the incompatibility between heavy cargo traffic and the existing urban road infrastructure. Carriers experience waiting for up to 30 hours on access routes to TPG and NAPORTEC, generating noise and air pollution that directly affect the sector's 100,000 inhabitants. This project designs two exclusive access alternatives through microsimulation in AIMSUN and rigid pavement under AASHTO 93 methodology. Field surveys recorded gate processing times of 3:52 min for dry trailers and 5:58 min for refrigerated ones at NAPORTEC, with daily volumes of 730 and 660 trucks at TPG and NAPORTEC respectively. The baseline scenario simulation showed queues of 235.72 vehicles and 12,465 total stops during the analyzed period. The proposed solution reduced queues by 21.6%, the number of stops by 43.8%, and consequently decreased CO₂, NOx and particulate matter emissions, as well as noise levels. The structural design includes concrete slabs with f'c=350 kg/cm² at 300 mm thickness, 150 mm granular base, ø38mm dowels and ø16mm tie bars, on subgrade with CBR=40%.
