Journey-to-Work Occupants per Trip from 2001 Nationwide Household Travel Survey (FHWA 2001) (see http://nhts.ornl.gov/2001/index/shtml) as follows:<br />

1.32 occupants per Construction, Manufacturing, TCU, and Wholesale trip<br />

Daily Occupants per Trip from 2001 Nationwide Household Travel Survey (FHWA 2001) as follows:<br />

1.38 occupants per Construction, Manufacturing, TCU, and Wholesale trip<br />

1.73 occupants per Retail Trade, FIRE, and Services trip<br />

(1) The equation to determine the Functional Population Coefficient per Employee for all land-use categories except residential includes the following:<br />

[(Employee Hours x Days per Week) + (Visitors per Employee x Visitor Hours per Trip x Days per Week)]<br />

(24 Hours per Day x 7 Days per Week)<br />

(2) Square feet per retail employee from Energy Information Administration (2002) from Table B-1 of the Commercial Energy Building Survey 1999<br />

Similar to Table II-9 above, the following table provides the general functional<br />

population coefficients for nonresidential uses/categories in IRC for the year 2004 based<br />

on an 11 hours per day, 5 days per week analysis.<br />
