1. Introductions
2. Development Overview
JMcD summarised the current development proposals for Dargavel Village (ROF Bishopton),
confirming that the only element that will change from the consented Masterplan is the foodstore.
The 2008 Transport Assessment considered a foodstore with a gross floor area of 2,500m 2
(although it is acknowledged the outline consent is for 1,000m 2 ). It is proposed to enhance the
foodstore content from 2,500m 2 to 6,000m 2 . This increase in GFA is in response to a household
survey that reviewed Bishopton shopping trends and the consideration of the requirements of a
2,500 increase in housing supply.
3. People Trip Generation
SL advised that as the 2008 TA had already considered a 2,500m2 foodstore, it is proposed to
only assess the net-increase in vehicle trips on the wider local road network. JMP had prepared a
note of the proposed methodology to calculate the travel characteristics and vehicle trips for the
6,000m 2 foodstore and this was discussed at the meeting.
a) Analysis Period – JE agreed the critical assessment period for the proposed Masterplan with
a 6,000m 2 foodstore is the weekday PM peak period.
b) People Trip Assessment – JMP proposes to use latest survey data from the TRICS database
(2012b) to calculate the total people trips and the mode share. JE confirmed this is
acceptable.
c) External & Internal Trip Distribution – The 2008 TA assumed that all of the trips associated
with the 2,500m 2 foodstore would originate from the Masterplan site and have no impact on
the wider road network. While the increase in floorspace will clearly generate trips from
outwith the Dargavel, JMP propose to adopt a similar approach to the 2008 TA by discounting
‘internally’ generated trips. JE agreed this approach was acceptable.
SL advised that while the retail impact assessment has yet to be completed, the early results
indicate that the vast majority of the additional custom will come from the existing Bishopton
Village. It is proposed to base the ratio of internal (Dargavel) and external (Bishopton) trips on
the number of houses upon full completion of Dargavel. This equates to 57% Dargavel and
43% Bishopton.
