I am working on Simplified Trip on Project Software(STOPS) which is for the estimation of transit demand. Unfortunately, I could not find any resource to find this software conceptually, although it is easy to work. If any one understands this chart conceptually, please explain.
Also, I found that highway supply part is computed by following formula:
PMHT(I,J) = ∑ [highway person-trips(i,j) x highway distance(i,j) + auto-access trips(i,j) x auto-access distance(i,s)]
Where: I, i = production district and zone
J, j = attraction district and zone
s = stop used for park-ride or kiss-ride access
∑ = sum over all i,j within each I,J
PHMT change(I,J) = Build PMHT(I,J) minus No-build PMHT(I,J)
And the Home-Based-Work part for demand:
Normalized CTPP transit share x [C x t(a) x CTPP workers(a)]
= linked HBW transit trips in rider-survey datasets
Can anyone introduce some resources that explain these formula and their usage to know about the inputs and outputs?
Well, you can find some PowerPoints around, but I confess that the technical details are not explained. Did you try to contact Jeffrey Roux, the author of STOPS ?
Hi,
Unfortunately, there is no details and there are several questions that I do not think it will be eliminated via email. Do you know, for instance, what is the Trn load for?
Probably the transit flow (n representing the number of vehicles). Did you have a look to http://i26alt.org/wp-content/uploads/APPENDIX_6C_Travel-Demand-Forecasting-Memorandum.pdf ?
Dear Sir,
pl check it.

Soory, I can't help further with this. I would suggest to ask J. Roux if he has some, even unpublished, papers on STOPS...
