3.26 Table 3.5 indicates that the proposed foodstore will generate 191 new two-way vehicle trips onto
the existing local road network during the weekday PM peak period.
Step 5 – Distribution and Assignment
Distribution
3.27 It is anticipated that the principal catchment area for the proposed foodstore will be the immediate
local area of Bishopton, ostensibly capturing the existing demand that currently is lost to adjacent
foodstores in Erskine, Port Glasgow, Braehead and Linwood. It is not anticipated that there will be
a significant level of traffic attracted from areas outwith Bishopton.
3.28 Given the distance to the proposed foodstore will be shorter than that currently undertaken by
residents travelling to similar stores outwith Bishopton, the distribution of development traffic has
been determined on the number of houses for each census output area in Bishopton. The
distribution of development trips throughout Bishopton Village is indicated by Figure F8 in
Appendix F in the Appendices Report.
Assignment
3.29 Given the location of the foodstore in relation to the existing Bishopton Village, it is anticipated the
majority of existing residents from Bishopton will likely use Station Road as the main point of
access from the A8 Greenock Road. While the northern access road may provide an alternatives
route for residents in the north of Bishopton Village, Renfrewshire Council has requested we
assume 100% of traffic will use Station Road. This will therefore provide a robust analysis of the
development’s potential impact on this section of the local road network.
3.30 Vehicle trips have been assigned to Station Road via the A8 Greenock Road based on the most
appropriate route while taking into account not only distance but travel times from the various
census output areas that make up Bishopton. This is indicated by Figure F2 in Appendix F.
Summary of Foodstore Travel Characteristics
• TRICS 2012(b) data indicates the 6,000m 2 foodstore is likely to generate a total of 988 two-way
people trips during the weekday PM peak period;
• TRICS 2012(b) data also indicates the foodstore will have a mode split of 11% walk, 1% cycle,
2% public transport, 23% car passenger and 64% private car;
• Of the total 636 two-way vehicle trips, 273 trips will originate from Bishopton Village using the
existing local road network. The remaining 363 trips will be contained with Dargavel Village;
• With an allowance of 30% pass-by / diverted trips, there will be 191 two-way vehicle trips on
the local road network during the weekday PM peak period. This is in addition to the 2,096 twoway
trips considered by the 2008 Transport Assessment and consented for the overall
Dargavel Masterplan.
