HBWTRIPS $=0\mathrm{.}01+(0\mathrm{.}3*$ NCARS$)+(1\mathrm{.}60*$NWORKERS$)(1)$

HBOTRIPS $=0\mathrm{.}01+(1\mathrm{.}1*$ HHSIZE$)+(0\mathrm{.}60*$ NCARS$)-(0\mathrm{.}60*$NWORKERS$)(2)$

HBWTRIPS Total number of home$-$based work trips produced by a household during a $24-$hour period

HBOTRIPS Total number of home$-$based non$-$work trips produced by a household during a $24-$hour period

HHSIZE Number of people in the household

NWORKERS Number of workers in the household

NCARS Number of cars in the household

Therefore, according to equation $1,$ a $1-$car, $2-$worker household will produce, on an average, $0\mathrm{.}01+0\mathrm{.}3(1)+1\mathrm{.}6(2)=3\mathrm{.}51$ trips

If there are $1000$ such households, these $1000$ households will collectively produce $3\mathrm{.}51*1000=3510$ HBW trips.

The following socio$-$economic forecasts are available for the study region:
