Background

**********



This program was originally developed at the State University of New York at 

Stony Brook by T. O. Carroll, Y. Chan, R. Silkman, and T. Sexton (1982).  The 

study is documented in Chan and Carroll (1985).  Subsequent extensions 

were performed at Washington State University and the Air Force Institute of 

Technology by Y. Chan and his associates. This program, STATEPRK, generates 

demand for state-park visitation and allocates the demand among competing 

state parks. The New York model is described in Section 5.1 of the "Activity 

generation and allocation" chapter of the Chan (2005) book, entitled 

LOCATION, TRANSPORT AND LAND-USE, including the data.



The Program

***********



The STATEPRK contains the following files:



PARKNY.ASC :  BASIC source-program containing the New-York-Parks data written 

to run under the GWBASIC compiler.



NYPARKS.BAT :  DOS batch file that initiates GWBASIC, which compiles and 

executes PARKNY.ASC.



PARKWAS.ASC : BASIC source-program containing the Washington-State-Parks data 

written to run under GWBASIC.



WASPRKS.BAT :  DOS batch-file that initiates GWBASIC, which compiles and 

executes PARKWAS.ASC.



GWBASIC.EXE :  BASIC-program compiler that turns PARKNY.ASC and PARKWAS.ASC 

into executable codes.  A short text-file that explains the most basic of 

GWBASIC commands is contained in the file BASIC.TXT at the BOOK root 

directory.



Additional information

**********************



1.  The model (and particularly the input/output data) behind the New-York-

Parks Program is explained in the Chan (2005) book under the "Activity 

generation-distribution" chapter, as pointed out above. Data for the 

Washington Parks program is similar.



2.  A program with existing New-York-State data has been prepared already. To 

run the New-York-Parks Program, simply type in "NYPARKS" to initiate the 

compilation and execution.



3.  A program with existing Washington-State data has been prepared already. 

To run the Washington State Parks Program, type in "WASPRKS" to initiate the 

compilation and execution.



4.  Being developed in a university setting, the codes are written in a 

prototype style. In order to run a new dataset, one needs to go into the 

source program and change the "DATA statements;" then re-compile.
