Traffic Assessment - Renfrewshire Council

Secondary Education
4.52 The secondary school trips from outwith the development site would potentially qualify for bus
travel to and from the school. Assuming a bus occupancy figure of 50 pupils per bus would equate
to a required provision of 8 buses to transport pupils to and from secondary school.
Further Education
4.53 As detailed in paragraph 4.16 further education student trips will be discounted. It is therefore
necessary to establish the number of trips associated with students.
4.54 By examining Table CAS218 in the National Census for the Bishopton ward it can be seen that
there are 171 full time students in the 16 to 24 age group. Assuming that within this age group,
students between 16 and 18 could still be at school. Consequently within the overall age band, two
years can be discounted. To compensate for this, only 75% of the total will be considered giving a
total of 128 students. Using the same principles for students who are also in employment a figure
of a further 137 students is obtained. Additionally, there are another 69 older students which gives
a student total of 334 students.
4.55 As a percentage of the total population this equates to 11.2%. By applying this to the calculated
trip rate, a trip rate for students can then be calculated and this equates to 296 trips in the AM and
264 trips in the PM.
External Trip Generation
4.56 Table 4.10 indicates the number of people trips generated by the residential and employment
elements of the development.

the previous section on Internal Trips and are summarised in Table 4.11.
