Variable General Info
Number of car visits to beaches ?Comment:Log visits to beach i on day t. |
Number of visitors to beaches ?Comment:Predicted beach attendance in terms of number of visitors, was converted from cars to people by multiplying car counts by three, which the town of Barnstable uses when estimating visitation to their beaches. |
Season total number of visitors to beaches ?Comment:To estimate total attendance at each beach for the whole summer season, other factors must be considered. Given the variability in weather conditions, we predicted a summer season by averaging results using four seasons of weather (2012-2015). The town of Barnstable starts collecting parking fees on Memorial Day weekend and stops by Labor Day weekend, and these holidays can fall on different days each year. Therefore, a summer season for Barnstable can vary by a couple of weeks, but on average, there are 107 beach days that make up a summer season. Using predicted visits within the four years, we calculated the average total visits for a single summer. This prediction process was simulated two thousand times, drawing from the distribution of coefficient estimates and random effects to account for uncertainty in our visitation model. |
