Mode Choice - Nesting Coefficients

Hello,

Can anyone please verify if I am using the nesting coefficients in utility equations and XCHOICE model correctly? 

Utility equations and mode choice model included below

C_NEST1 = 0.5, C_NEST2=0.5, C_NEST3=0.5

The utility calculations:

Drive Alone

    MW[201]= (C_IVT*MI.2.1 + C_COSTINC1*((MI.2.2/10*AUTOOPCOST) + MI.2.3 + HBW_PARKCOST_J/2) +  C_OVTERM*(TERMTIME_I+TERMTIME_J) +  Constant ) / C_NEST1

C_NEST1=0.5 nesting coefficient for highway nest

HOV2

MW[202]= (C_IVT*MI.2.4 +  C_COSTINC1*((MI.2.5/10*AUTOOPCOST) + MI.2.6 + (HBW_PARKCOST_J/2))/OCC2 + C_OVTERM*(TERMTIME_I + TERMTIME_J) + Constant )/ C_NEST12

C_NEST12=0.5*0.5 = nesting coefficient for highway nest * for shared ride nest

HOV3 is similar.

PnR Metrorail

  MW[214] = (C_IVT*MI.5.DIVTT/100 + C_AAT*(MI.5.DACCT)/100 + C_OVTERM*(MI.5.DINIT + MI.5.DXFRT + MI.5.DPRKT)/100 + C_XFERS*MI.5.DNXFR +         C_COSTINC1*(MI.5.DFARE+MI.5.DPRKC+(MI.5.DACCD/100*AUTOOPCOST))+  C_BRDPEN*MI.5.DXPEN/100 + C_WLKWT*(MI.5.DWAET+MI.6.DWLKT)/100  +MI.7.14 + L_PNR_KNRtoTR) / C_NEST123

C_NEST123=0.5*0.5 = nesting coefficient for transit nest * for access nest
