build internal junctions for tls left-turns by default #6277

Open namdre opened 4 years ago

namdre commented 4 years ago

currently, internal junctions are only built when the loaded tls program requires them (i.e. built for layout opposites but not for layout incoming. This may lead to unexpected behavior when later loading a program that would require them (i.e. building with layout incoming and loading layout opposites).

By default, internal junctions should be built for left turns when there is an opposite-straight connection. Legacy behavior should be available via a new option --tls.reduce-internal-junctions

Changing the default behavior also has downsides: in networks with pedestrian crossings the internal junctions for left turns are moved to the junction interior instead of close to the crossing
