Abstract

Owing to unique conditions and urgent circumstances associated with travel between Portmore and Kingston, Jamaica, a special investigation was added to the Terms of Reference (TOR) for the World-Bank-sponsored Jamaica Transport Sector Study carried out during 1993. Alternative modes for improving travel conditions in this congested corridor were quantitatively compared. The TOR called for a simplified sketchplanning corridor study. Based upon order-of-magnitude study results, a modal strategy was formulated. Lastly, TOR were prepared for a feasibility study to detail the selected modal strategy and to set out the implementation schedule and mechanisms for action, including funding means. The study assessed the potential contributions of roadway, bus on roadway, suburban rail, and passenger ferry options. Results demonstrated that, by far, the highest returns would be achieved with roadway (causeway plus bridge) upgrading combined with bus enhancements.
