For node evaluation (*.KNA), why do some movements have 0 volume although we could see traffic flows there by looking at the visualization?
The node evaluation uses automatically created travel time measurements to evaluate the number and delay of vehicles for all movements. The start of the travel time section by default is max. 100m upstream of the node boundary where the link enters the node (see “Start of delay segment” in “Evaluations – Files… – Node [Filter]”). In the following cases this distance “d” is shortened: • the link is shorter than d • the next upstream node is less than d meters away. Then the start of the travel time section is placed directly at the next upstream node boundary. If a parking lot is placed between this node and the one to be evaluated, then the travel time section does not count all the vehicles that emerge from that parking lot.There are different options to solve the problem: • Increase the length of all short entry links and place the parking lots at least d meters upstream of the node boundary. • Decrease d so that it accomodates for all the short entry/exit links. • Place the parkin
