Specifications

According to the OAAA the DEC is calculated by assuming that each vehicle contains 1.38 people (18 years and older). That variable is divided into two (to measure only one direction of the road). This data was provided from the Ministry of Transport and Public works of Puerto Rico which was published in January 2005 with data pertaining to 2003. These statistics assume outdoor media is featured with 24 hours of illumination.
