Re: [sumo-user] Avoiding lateral movement at low speeds with sublane model

Hello,
the lane-changing model SL2015 ( for the sublane simulation) offers the parameters 'lcMaxSpeedLatStanding' and 'lcMaxSpeedLatFactor' (somewhat experimental and not documented until now:

)

Hi,

 

first a background-information for my question: we are using SUMO at TESIS GmbH for Co-Simulation with our tool DYNA4 which includes a high-fidelity vehicle model (MBS axles, sensors, etc.) and our 3D animation. We’re very impressed with the possibilities SUMO offers, because we can easily create complex traffic scenarios for ADAS/AD development.

 

We’re using the sublane model usually, mostly because of the non-instantaneous lane changes and the more realistic behavior of mixed car/bike lanes. However, what causes some trouble for us is the lateral movement of vehicles at low (or no) speeds, e.g. in front of red traffic lights or when dissolving a queue on a highway. It would be great, if there was a parameter which defines a threshold for longitudinal speed below which no lateral movement is possible. I know it’s a special request for more realistic vehicle movement, but I do believe it also has an impact on queue length / dissolving times, which are relevant for traffic engineering related tasks. Would this be possible to implement without major interference with other parameters and/or problems with interconnection of car-following model and lane-change model?

 

Thanks

 

Jakob
