Utility and probability calculations with transit as the base alternative.

Alternative	Utility		Exponent	Probability
	Expression	Value
Drive alone	$U_{DA}={\mathsf{\beta }}_{DA,1}INC-{\mathsf{\beta }}_{2}T{T}_{DA}$ $=0.004\times 50-0.02\times 30$	−0.4	0.6703	$P_{DA}=0.65$
Transit	$U_{TR}={\mathsf{\beta }}_{TR,1}INC-{\mathsf{\beta }}_{2}T{T}_{TR}$ $=0\times 50-0.02\times 50$	−1	0.3679	$P_{TR}=0.35$
	${\mathsf{\beta }}_{DA,1}=0.004$; ${\mathsf{\beta }}_{TR,1}=0;{\mathsf{\beta }}_2=-0.02$		${\displaystyle \sum }=1.0382$
