| Re: [sumo-user] Calculate total distance travelled |
You can use trac.load instead of trac.loadStatetraci.load restarts the simulation with new options which allows to load from a state but can also reset output file paths._______________________________________________Am Do., 25.

I am starting a simulation and lets say it runs for 10 seconds and then I make a saveState (let's call this state 0). During this time 3 cars have finished their journey and their info was written in the tripinfo file. I continue the simulation for 10 more seconds (let's call this simulation 1) and 2 more cars' info is written in the file, I calculate the distance driven by all cars so far. Now I use loadState to load back state 0, that I saved earlier without stopping the simulation (traci.close) and I do another 10 seconds simulation with a bit of randomness and try to calculate the distance again. The problem is the 2 cars from simulation 1 are still there in the file. Is there a way to restore the tripinfo file to the same state when state 0 was saved. Or is there a way to specify a different tripinfo file with loadState.On Tue, Feb 16, 2021 at 2:13 PM Jakob Erdmann <namdre.sumo@xxxxxxxxx> wrote:set option --tripinfo-output.write-unfinished_______________________________________________Am Di., 16.

Abdullah <ab11@xxxxxxxxxxx>:Hi,I have tried the --tripinfo-output option to get the total distance traveled by all vehicles but it only gives me the values for those vehicles that have reached their destination. Is there a way get distance travelled by both vehicles that are still in the networking and those that have finished their journey, together at the end of a simulation.On Sat, Feb 13, 2021 at 12:29 PM .

The tripinfo file contains the total travel distance for every vehicle which has finished its trip. You just need to parse it.Thanks,_______________________________________________On Fri, Feb 12, 2021 at 3:26 PM .

Currently, I am doing the following after every simulation step: get the list of all vehicle ids using traci.vehicle.getIDList() and then iterate over the list and call traci.vehicle.getDistance(vehid) and save this value to add up later.This becomes very slow as the number of vehicles increases over time. If I do this once at the end of the simulation then I lose the information about vehicles that have reached their destination between start and end.I was wondering if there is a way of finding the total distance travelled once at the end of the simulation that also takes into account of all the vehicles that have left the network.--Thank you.Abdullah
