Yeah essentially travel speed was slower than RapidTO (the business as usual scenario), which means that less riders are modeled to use the line/system since it is slower than before and less competitive with other modes. I don't believe bus network changes were coded in.
This is why you make sure your future population forecast considers induced growth from the new MTSAs. This is why you consider travel time reliability and variability differences of LRT vs. curbside bus lanes in your travel demand model. This is why you re-design your project if it isn't achieving its original strategic goals (although not convinced speed was a goal). This is why you do the work to determine what the post-LRT transit network looks like to improve transfers and mitigate slower travel speeds if they do exist.
And btw, for those with keen eyes, there has been some very recent progress on the EELRT file.
