Effect of 0 pce on travel times of other vehicles (and link capacities)

I am simulating two modes "ride" and "school bus" by setting their pce to zero along with other modes like "car", "pt", "bicycle", and a teleported "walk" mode. I am doing this because, I need to get an estimated route for the "ride" and "school bus" modes. This is based on Dr. Nagel's advice to me in the past, although he cautioned of potential issues while doing this. Can you please let me know if simulating such 0 pce modes influence the travel times of other vehicles or the capacity of the links? Theoretically, it shouldn't but getting a clarification would make me rest a bit easy.

Zero-PCE vehicles do not influence other vehicles directly. However, link enter/leave events generated by them are taken for calculating the average link travel times. Then these averaged times will be used for routing of all vehicles in the next replanning phase (next iteration) if the average travel times are not calculated separately for each mode.

BTW. The threshold for flow capacity easing is set by default to 0 (more info: ). If you do not want to have it turned on, set the threshold to a negative value.

Hope that helps,
