Re: [sumo-user] Question about GetLanePosition and GetPosition

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

- getPosition refers to the Cartesian coordinate plane. The origin point of 0,0 is usually the lower right network corner so coordinates are mostly positive. However, nothing prevents a user from shifting his network or adding new edges in another quadrant (and nothing bad comes of it).

- getLanePosition is the distance from the start of the current lane so this value is reset to 0 everytime the vehicle drives onto a new lane.

- The best way to obtain a distance to a point along the current route is to call `traci.vehicle.getDrivingDistance` . Otherwise you're better of with `traci.simulation.findRoute` which will return the route to that location as well as it's length.

Hi Everyone,

I am not able to get the concept of GetLanePosition and GetPosition in Sumo. I want to check the vehicle's distance from a specific junction, for example, Junction J1. So I can calculate the vehicle's arrival time. Which one should I use?

One more thing,

What is the meaning of negative values in GetPosition?

Regards,

Shraddha
