Simulation and outdoor recreation

摘要

Outdoor recreation systems are comprised of three basic components: (1) a set of N population centers, (2) a set of M recreation sites, and (3) a set of at least NM connecting links. An important problem facing planners in the allocation of resources is how to estimate the magnitude of travel per unit time flowing in systems of varying characteristics. Simulation is viewed to be one possibility. A gravity-type model written in GPSS III was developed to simulate travel in a system comprising most of the Commonwealth of Pennsylvania in order to explore the possibility of examining the effects of:

rn

(a) adding new parks

rn

(b) constructing new highways

rn

(c) a rise in the level of participation.

Data collected in Pennsylvania during the summer of 1968 were used as applicable.
