In Puerto Rico, the first cycle of the SHSP had a one-year period and was in fiscal year 2013. This was an interim plan developed by a technical team between the Commission for Traffic Safety (CST), the Highway and Transportation Authority (ACT) and the Department of Transportation and Public Works (DTOP). The interim SHSP was submitted to the Federal Highway Administration (FHWA) on April 18, 2013. This was the first step in aligning the efforts of a road safety plan in Puerto Rico. The 2014-2018 SHSP was then developed in July 2014 with the signing of a Memorandum of Understanding (MOU). The MOU was signed by the leading agencies in road safety in the country: DTOP, ACT, CST, the Department of Health and the Puerto Rico Police. In addition, federal agencies FHWA, NHTSA and FMCSA signed the MOU as a sign of their support and commitment to Puerto Rico. The 2014-2018 SHSP promoted that initiatives to reduce traffic crashes be coordinated among road safety delegates, thus fostering a participatory and collaborative process. So much so that, in 2016, the union of the third sector was formally presented as ALIANZA, which is composed of AARP, MAVI, Sociedad Puertorriqueña de Planificación, ITE and Fundación MAPFRE. The purpose of this alliance is to promote, from the third sector, public policy and design educational campaigns to improve mobility, accessibility and safety on the country’s roads. On the other hand, the 2014-2018 SHSP was based on nine (9) areas of emphasis, while the interim SHSP defined only four (4). The new 2019-2023 SHSP is the step to ensure continuity to the work done for the last five years and to continue in compliance with the aforementioned federal regulation. This plan is intended to be more agile, with a reduction in the areas of emphasis, so as to maximize resources and work on strategies and actions more focused and directed to achieve the established goals. The following figure shows a summary of the most important events during the development and implementation of the SHSP.
