Traffic Study A traffic study was conducted to determine the impa ct of increased development on traffic in Los Llanos. The purpose of the traffic study is outlined by the following: 1) To determine peak flows and direction of traffic 2) To document the composition of traffic 3) To determine whether traffic is local in origin, o r if it is generated outside Los Llanos and passing through Methodology To achieve these objectives a traffic count study w as carried out in the following way. Three locations were chosen in Los Llanos were traffic counts were taken at 7am, 12pm, and 5pm. The counts took place for 30 minute s at each site on two different days. The three locations that were chosen are illustrated on the map below. The cemetery was chosen to capture the traffic flow that is likely o ccurring due to the residential area nearby. The tool booth was chosen to capture the t raffic that is coming on the main road that also leads to the Pan-American Highway. The s chool was chosen because of its location outside of Los Llanos but on the way to th e Pan-American Highway, thus acting as a control variable to determine if traffic is or iginated locally or from outside the region. The traffic passing the location of the tol l booth includes both local traffic and traffic coming from the Pan-American Highway. The t raffic passing the school is traffic that is coming and going from beyond Los Llanos and is thus outside traffic. Therefore the traffic from the toll booth minus the traffic c ounted at the school can be assumed to be local in origin. In other words, the school loca tion allows for the separation of locally generated traffic and traffic that is coming from o utside the area. Data was collected by pairs of students at each loc ation on a Thursday and a Monday to account for the differences that occur du e to the time of week. Students documented both the types of traffic including pede strians, and various types of motorized vehicles as well as whether the vehicles were heading towards or away from Santa Elena. Findings The following major conclusions were made after ana lyzing the data. 1) In all three locations traffic flowed toward Santa Elena in the morning and away from Santa Elena in the evening. 2) For all three locations, Monday had significantly m ore traffic than Thursday 3) The toll booth had the highest amount of traffic wi th an average of 24.2 incidents of traffic per half hour. The cemetery had the sec ond highest traffic count with 21 incidents of traffic during a half hour, and the school had significantly less traffic overall (10.5 traffic incidents per half hour) indi cating that most traffic is local in origin. All averages calculated here are averages o f booth Thursday and Monday as well as an average of traffic during the three d ifferent times of day. 4) The types of traffic varied significantly as shown in the diagram below. In general there was more pedestrian traffic at the tw o locations closer to Santa
Elana and more commercial traffic at the location t hat leads directly to the PanAmerican Highway.
