Activity Methodologies

For transit trips and transit VMT

$VT_{BUS,A}=VT_{BUS,P,A}+VT_{BUS,OP,A}$ $VT_{BUS,B}=VT_{BUS,P,B}+VT_{BUS,OP,B}$ $VT_{BUS,P,A}=\frac{1}{H_{BUS,P,A}}\times h_{P,A}$ $VT_{BUS,OP,A}=\frac{1}{H_{BUS,OP,A}}\times h_{OP,A}$ $VT_{BUS,P,B}=\frac{1}{H_{BUS,P,B}}\times h_{P,B}$ $VT_{BUS,OP,B}=\frac{1}{H_{BUS,OP,B}}\times h_{OP,B}$ $VMT_{BUS,P,A}=VT_{BUS,P,A}\times L_{BUS,A}$ $VMT_{BUS,OP,A}=VT_{BUS,OP,A}\times L_{BUS,A}$ $VMT_{BUS,P,B}=VT_{BUS,P,B}\times L_{BUS,B}$ $VMT_{BUS,OP,B}=VT_{BUS,OP,B}\times L_{BUS,B}$

For auto trips and auto VMT

$VT_{R}=VT_{R,P}+VT_{R,OP}$ $VMT_{R}=VMT_{R,P}+VT_{R,OP}$ $R=R_{P}+R_{OP}$ $R_{P}=R\times F_{P} \times h_{P}$ $R_{OP}=R\times F_{OP} \times h_{OP}$ $VT_{R,P}=\frac{R_{P}\times r_{R,A} \times (1-P_{C})}{O_{A}}+\frac{R_{P} \times r_{R,A} \times P_{C}}{O_{C}}$ $VT_{R,OP}=\frac{R_{OP}\times r_{R,A} \times (1-P_{C})}{O_{A}}+\frac{R_{OP} \times r_{R,A} \times P_{C}}{O_{C}}$ $VMT_{R,P}=VT_{R,P} \times L_{A}$ $VMT_{R,OP}=VT_{R,OP} \times L_{A}$
