There is a need to add a block of time (such as 30 seconds) to a network solve for elements such as a stop lights/signs or a Railroad crossing. I don't want to create a scaled-cost barrier for them as it is dependent on the times of the segments coming into contact. If there were a way to either edit the junction or create a separate added cost point to an intersection, I could solve this issue. I am involved in the routing of school buses and our buses are required to stop at Railroad crossings. I would like to be able to place a fixed amount of time (say 20 seconds) to that intersection to account for the driver stopping, opening the door, verifying safety and then proceeding onward. Or, if I was able to input stop lights and account for the time a particular stoplight typically takes. The nearby street segments are being attributed on an average free-flow street speed. These instances are not completely related to free-flow speeds. Thus, slowing down traffic by using a scaled cost barrier does not account for these full stops. It would be great to just add an amount of time to a solve as defined by a file with a field denoting the stop times.
