Hi, I´m trying to simulate a free way (no intersections) to calculate the emission of gases, but I don´t know how to do that.. the program doesn´t work when there is no node.
thanks for your help!

You might want to check and see that synchro will satisfy the environmental requirement for whatever study you're doing.

check the Fuel and Emissions Calculation help topic in Synchro 6.
