| [sumo-user] Optimizing traci.edge.subscribeContext for Vehicle Data Retrieval |
|
Dear SUMO Community, I am using the following 'TraCI' command to obtain all vehicles moving on a specific edge while retrieving their speed and lane ID. As the lane length, I use half of the edge length: traci.edge.subscribeContext(edgeID, traci.constants.CMD_GET_VEHICLE_VARIABLE, length, [traci.constants.VAR_SPEED, traci.constants.VAR_LANE_ID]) However, I have noticed that some vehicles in my results are actually on different edges. I suspect this is because the distance parameter works as a circular range rather than strictly along the edge. I have two main questions: A. Is there a more efficient 'TraCI' call to obtain vehicle data for a specific edge? B. What would be an optimal value for the distance parameter to improve performance while ensuring only vehicles on the target edge are included? I appreciate any insights or recommendations. Με φιλικούς χαιρετισμούς / Kind Regards
