4.35 While this figure demonstrates the number of employment trips which can be discounted as the
origin of the trip will be within Bishopton, it must also be remembered that the figure for generated
trips from the residential area to employment will also include the trips where the destination of the
trip stays within the development employment in Bishopton. Consequently, this discounted figure
will require to be discounted against both the residential and employment elements.
Trip Generation
Residential Element
4.36 The number of people trips generated by the development has been estimated from the TRICS
database as previously presented in the Scoping Report produced by JMP in June 2005. Table 4.6
below indicates the residential trip rates obtained and the resultant people trips associated with the
residential element of the proposed development.

Non Residential Element
4.37 There is a significant non residential element (154,179sqm) within the development which is
predominantly made up of employment development (138,000 sqm) which accounts for just under
90% of the non residential element. The remainder (16,179 sqm) is a combination of commercial
and community uses. For the purposes of the transport impact calculations, commercial uses are
assumed to be a mix of general shops and a 2,500sqm supermarket, while the community uses will
be made up of facilities such as a primary school and health centre.
