Re: [sumo-user] Question about SUMO Filter

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

Hello,

the above filters are intended to return vehicles which are driving in the same direction as the ego vehicle. There is currently no filter for an ellipsoidal shape.

regards,

Hello Sumo Community

I tried to test the Sumo Filter

    traci.vehicle.addSubscriptionFilterDownstreamDistance(200.0) and

    traci.vehicle.addSubscriptionFilterUpstreamDistance(200.0)

I through that,  with this both Filter function we can have in the defined distance along the network all vehicles in the last simulation step. I was wondering why this Filter-method don’t give the value of vehicles which is on the opposite lane, even if this vehicle in the define upstream and downstream.

These two methods just give values of vehicles which is in the same direction of ego ?

Like I understand this method is like a unequal ellipsoid. So that the user can define how long forward the ellipsoid would be (UpstreamDistance) and how long in behind (DownstreamDistance)

If this is not the Case which kind, of Filter could we use to be able to have a king of ellipsoid with is not lane or route specific.

 

Thak you for your help
