Sublane-Model

This page describes simulations with increased lateral resolution. This model is activated using the option lateral-resolution <FLOAT>. The model is described in [missing link!].

New Parameters

The vehicle behavior is subject to model-specific vType attributes (maxSpeedLat, minGapLat, latAlignment) and lane-changing-modell attributes (lcSublane, lcPushy).

Model Details

The regular lanes of the road network are divided into subleases with a minimum width of the given resolution (--lateral-resolution). If the lane width is not a multiple of the given value, the leftmost sublane has a reduced with.

Vehicles occupy one or more sublanes and perform car-following calculations for all vehicles that are being followed on at least one sublane. Lane-changing takes place at the sublane level and potentially uses the whole width of the road according to the width of the vehicles. Besides changing for route-following, cooperation or speed gain, vehicles also perform lateral movement to achieve a certain lateral alignment. This preference for either staying in the middle of a lane or to one of its sides is configured with the vType attribute latAlignment.
