ACRER - Accessibility for Recreation in R

Recreation model that simulates household types, group types, expected visiting duration, and total visits from city zip codes to surrounding destination areas. The methodology is based on the accessibility model described in Bervaes et al. (1996) "Een model voor het gebruik van de groene ruimte in stadslandschappen (Fase I)" <https://www.wur.nl/en/library>, with optimization procedures based on Goldfarb and Idnani (1983) <doi:10.1007/BF02591962> and Vanderbei et al. (1986) <doi:10.1007/BF01840454>.
