Traffic Assessment - Renfrewshire Council

4.10 It has been assumed that all people trips within the AM period will be arrivals and that 100% (550)
of new primary pupil trips will be from within the development area. Consequently, no generated
trips for primary school pupils will be considered for the wider road network.
4.11 It has been assumed that all staff trips to the primary school will be external.
4.12 With regard to secondary school education, we have been informed that pupils originating from the
residential element of the proposed development will require to travel outwith the development site.
The secondary school children from the existing village currently travel by special school bus to
Erskine and the children from the new development will do likewise.
4.13 The likely number of secondary school pupils has been determined from Census data, particularly
household occupancy figures for Bishopton, which has been applied to the proposed total number
of development houses. The results of this calculation are indicated in Table 4.1.

4.14 Table 4.1 indicates that the proposed development is likely to generate 382 secondary school pupil
trips. Notwithstanding, it should be noted that the number of pupils has been taken from the 12 to
15 age band and therefore does not account for 16 to 17 year olds attending secondary school.
We would therefore consider the figure of 382 pupils to be robust in terms of assessment.
4.15 On the basis that Erskine is remote from most of the main destinations from Bishopton it has been
assumed that all people trips will be either by the provided bus service or as drop off from other
trips with Erskine as a destination. Consequently, no additional generated trips for secondary
school pupils will be considered for the wider road network.
Further Education
4.16 There is a large number of trips associated with students that will occur in the peak periods.
However, the mode share associated with these trips is significantly different from that of the other
residents. As a consequence of this, a separate mode share has been established for students
and as a consequence further education student trips require to be deleted from the base trips
which are being considered for all other users.
Community Facilities
4.17 There will be a number of Community Facilities within the new development, such as the Health
Centre, which will equally serve the new development and the existing community. The isolated
nature of Bishopton will lead to extremely low use of the Health Centre from any other locations
outwith the existing Bishopton village and the proposed development.
4.18 Consequently, there will be no generated trips for visitors to the Health Centre or other Community
Facilities to be considered on the wider road network.
