🧵 10/? Travel demand modeling (TDM) takes a matrix of origin-destination trip volumes between zones and routes them through the nodes and links of the network to achieve equal travel times regardless of the path taken. While Cost-Benefit Analysis measures everything in money, TDM measures everything in time. For transit modeling, you assign time to inconvenience. With the National Rail Model we computed a time penalty for a crowded train to model behavior. (Some people wait for the next train.)
