<strong>Transit</strong><br />
• Nesting coefficients scale the utilities: U N (bus) = U(bus) / µ<br />
• Nesting coefficients take values between 0 <strong>and</strong> 1<br />
• Steeper diversion curve between nested alternatives<br />
• Smaller the nesting coefficient, the more similar the nested alternatives<br />
• When µ = 1, the model becomes multinomial logit (MNL)<br />
• When µ
