[sumo-user] what does 'overlapping' indicate in lcState ?

[Hao Zhou <zhouhaoseu@xxxxxxxxxx>]

Hello Jakob,

Hope you are doing well. A quick question on lcState info: what does 'overlapping' mean in the following case?

As the figure shows, the selected vehicle is going to make a lane change to its left. 'lcState left' says left|strategic|urgent|overlapping|blocked. Other key words are intuitive, but what does 'overlapping' mean here? Do you have any insights?

Also, where should such vehicles halt to find a gap for its strategic lane change? It blocks upstream traffic but its halting position looks random. 

Thank you and take care,
