Hi Jacob, Thanks a lot for your reply and consideration. I tried that, but I did not get what I expected. I am suspicious that I have done something wrong and would be grateful if you could advise. Please note we are left-hand side.
I put the code, input, and output below. Looking forward to hearing from you. Many thanksMohsen First: I created a taz file as follows: <tazs><taz id="1" edges="-16686683#3 16686683#3" /> <taz id="2" edges="-256521845#1 256521845#1" /></tazs> Second: My ofm file$O;D28.01 8.0211 2 52 1 1 Third: commandod2trips -n taz.taz.xml -d input_od_o.fma -o tripmatrix.trips.xml --scale 1 Forth: output (tripmatrix.trips.xml)<routes xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:noNamespaceSchemaLocation="http://sumo.dlr.de/xsd/routes_file.xsd";> <trip id="1" depart="28869.51" from="16686683#3" to="-256521845#1" fromTaz="1" toTaz="2" departLane="free" departSpeed="max"/> <trip id="2" depart="28870.32" from="16686683#3" to="-256521845#1" fromTaz="1" toTaz="2" departLane="free" departSpeed="max"/> <trip id="4" depart="28878.88" from="-16686683#3" to="256521845#1" fromTaz="1" toTaz="2" departLane="free" departSpeed="max"/> <trip id="0" depart="28895.35" from="-16686683#3" to="256521845#1" fromTaz="1" toTaz="2" departLane="free" departSpeed="max"/> <trip id="3" depart="28898.16" from="-16686683#3" to="256521845#1" fromTaz="1" toTaz="2" departLane="free" departSpeed="max"/> <trip id="5" depart="28915.65" from="-256521845#1" to="16686683#3" fromTaz="2" toTaz="1" departLane="free" departSpeed="max"/></routes> As shown above, for the first 5 trips (from zone 1 to zone 2), the 'from' should be the negative edge (-16686683#3) and arrival should be the positive edge (256521845#1). Unfortunately, the first two do not follow this rule. One more question please: how does od2trips can detect which edge is upstream and downstream without having the net.xml file as a parameter?

This can be done using traffic assignment zones which puts both edges (positive and negative number) into one zone. These zones can be generated automatically.

My collected data is like this: Source Street(SS), latitude of SS, longitude of SS, number of observed vehicles, Destination (DS), DS latitude, DS longitude, arrival time at DS I have generated net.xml for my city and I wrote an application to extract edges and store them in my database (db). I also wrote an application that can generate trips.xml for me based on the data in my db. I also stored lat, long, and street names from map.osm in my db. So I can easily correlate lat and long (from map.osm) with edges (from net.xml). The problem that I am facing is related to generating the trips based on the edges (to and from). I can find the closest edge to my SS/SD by finding the minimum Euclidean distance between SS/DSs' lat/long and edges' lat/long. But, I have difficulty in selecting the negative edge or positive edge as from/to. For example, after calculating the minimum Euclidean distance, the start point matches the following edges (see below screenshot) and the direction of travel (SS->SD) in my case is North. So, I have to select the negative one, but I can not do this manually. I was wondering if you could help me to find a way to automate this process. Please let me know if you need more information. Looking forward to hearing from you.
