Thanks Jakob, but I am more confused now. Consider these two cases:
Case 1: When I call SimulationStep starting from 0: - SimulationStep (0) --> advance simulation to the end of step 0 and simulationGetTime is now 500ms - SimulationStep (500) --> advance simulation to the end of step 500ms and simulationGetTime is now 1000ms. and so on… Case 2: Now, consider the case that I call SimulationStep starting from 500ms: - SimulationStep (500) --> advance simulation to the end of step 500, but simulationGetTime still shows 500ms - SimulationStep (1000) --> advance simulation to the end of step 1000ms, but simulationGetTime still shows 1000ms. and so on… Moreover, I can explain case 1 with the WiKi: In case 1, calling SimulationStep (500) should not advance the SUMO simulation cause the target time is smaller or equal to the current simulation step. right? - Mani From: Jakob Erdmann [mailto:[email protected]] Sent: Tuesday, September 26, 2017 3:16 AM To: Mani Amoozadeh <[email protected]>; Sumo project User discussions <[email protected]> Cc: sumo-user <[email protected]> Subject: Re: [sumo-user] Simulation Step TraCI call at time 0 Hello, when you take a look at the gui, you will find that the first call of simulationStep(0) advances the simulation to the end of step 0 (with vehicles departing at 0 already being inserted). Only the command simulation.getCurrentTime() already shows you 0.5 because all further traci calls will be processed at the start of the step that ends at 0.5 However, any vehicle positions you retrieve after the first call to simulationStep will be the ones from the insertion step 0. regards, Jakob 2017-09-26 10:35 GMT+02:00 Mani Amoozadeh via sumo-user <[email protected] <mailto:[email protected]> >: Hello, I setup a SUMO simulation with 0.5s time step in TraCI mode. Once the TraCI is established I subscribe to departed vehicles count and then insert 10 vehicles at time 0s. I call simulation step like this: simulationStep(500) --> simulationStep(1000) --> simulationStep(1500) . The first simulationStep returns subscription result that all 10 vehicles have departed. Is there any way to call simulationStep like this: simulationStep(0) --> simulationStep(500) --> simulationStep(1000) --> simulationStep(1500) . So that the first simulationStep call give me the subscription result showing that all vehicles have departed. Apparently, I cannot do this since 0 has a special meaning and proceeds simulation to 500ms. Is there any workaround for this?
