Traffic Assessment - Renfrewshire Council

Leisure
4.19 Trip purpose data presented within the Scottish Household Statistics report (TRN/2005/2) indicates
that approximately 5-7% of trips made during the peak hour are for entertainment or leisure
purposes. Therefore, we have assumed that 5% of the total residential trip generation will be
internal trips to the local residential community (i.e. trips from one house to another) and leisure
facilities such as the park.
4.20 Internal trips associated with the leisure and community facilities are as shown in Table 4.2 below.

4.21 As a result of this analysis it can be assumed that the figures in Table 4.2 can be discounted from
the total generated trips for the new development and will therefore not be considered for the wider
road network.
Commercial
4.22 It is expected that the majority of the trips generated by the local commercial facilities will also
remain within Bishopton due the isolated nature of Bishopton and the nature of the shops which will
result in few trips to Bishopton from external locations.
4.23 Most trips which are made to the local shopping facilities (i.e. non food retail elements) within the
new development as a separate trip are likely to be outwith the peak periods. Some trips are likely
to be made to the shops during peak periods but only as pass by trips for other destinations.
Consequently no reduction to the overall trips on the wider network will be made.
4.24 Most trips which are made to the supermarket element are likely to be discrete, as foodstuffs are
not a commodity that is likely to be kept in a car for a long period of time. However, on the return
journey to Bishopton it is possible that a number of trips may be made to the supermarket on the
way home and as such it has been assumed that 30% of the trips will be pass by trips.
4.25 Table 4.3 indicates the people trip generation associated with the 2,500 sqm GFA supermarket.
The trip rates used have been obtained from an interrogation of the TRICS database as detailed
before. The number of trips has been reduced to account for pass-by and linked trips.
