IDM: invalid emergency braking at yellow in subsecond simulation #14620

Open namdre opened 5 months ago

namdre commented 5 months ago

problem is caused by a mismatch between the brakeGap (IDM uses the default) and IDM::stopSpeed. When the light switches to yellow, the computed brakeGap indicates that safe and comfortable braking is possible but the stopSpeed function returns a value which corresponds to emergency braking.

@Domsall is this the same issue that prompted the implementation of EIDM::brakeGap?

Domsall commented 5 months ago

yes, i think so
