When does TNM stop acceleration for traffic on a roadway?
TNM will stop acceleration when it reaches its user input target speed (speed inputted in the traffic input tab), but will maintain full throttle throughout the entire segment. If the roadway is shorter than the length specified in Figures 43-45 in the TNM Technical Manual, then the traffic will not reach the target speed(s) by the end of the roadway. This is not a problem if the traffic has reached a high-enough speed (particularly above 40 mph) so that the cruise-throttle and full-throttle emissions are nearly the same.
