Sublanes

Sublanes is a new feature in SUMO since 2015. The simulation with Sublanes render traffic flows on roads more realistic. With sublanes, several vehicles can share side-by-side the same lane given there is enough room. For example a car can pass a bicycle on the same lane if the total lane width is larger than the bike width plus car width.

For sublane simulation with SUMOPy, simply browse to

    scenario.demand.vtypes

and set the lanechange model model to SL2015. Note that SUMOPy applies the same lanechange model to all vehicle types. Then run the simulation with

    Simulation>Sumo>export routes and simulate...

Note that on the SUMO dialog, the sublane width is now positive (1m by default). This value (which can be changed) determines how many sublanes can stay within one lane. For example a 3m wide lane can have 3 sublane of 1m but only 2 sublane of width 1.5m.

The lanechange behavior with sublanes can be tweaked for each vehicle type with the sublane parameters in `scenario.demand.vtypes`.
