Breakdown of the likelihoods of each signal given vehicle 's different possible stochastic attributes

Signal category	Value	Description	*
			Attentive cooperative	Attentive punitive	Distracted cooperative	Distracted punitive
Implicit: accelera-tion	0	observes no acceleration from	0.05	0.05	0.55	0.55
	1	observes deceleration from	0.55	0.3	0.25	0.15
	− 1	observes acceleration from	0.4	0.65	0.2	0.3
Explicit: e.g. eye contact	0	is unable to make eye contact with	0.1	0.1	0.95	0.95
	1	makes eye contact with	0.9	0.9	0.05	0.05
Explicit: e.g. gestures	0	does not observe an intention signal from	0.585	0.47	0.9275	0.9225
	1	observes a positive-intent signal from	0.36	0.09	0.045	0.0225
	− 1	observes a negative-intent signal from	0.055	0.44	0.0275	0.055
