11.38 Based on the traffic levels in Table 11.2 above, a Transport Statement is
the most suitable assessment for the proposed development as the
development trip generation lies well below the indicators for a Transport
Assessment. Therefore this construction traffic assessment fulfils the
requirements of a Transport Statement.
11.39 The total number of vehicle movements generated during the construction
of the proposed development is estimated as 10,768 over a 10-month
period. This takes account of all vehicle movements generated by the
above activities and includes site personnel. This total is broken down in
Table 11.2 above. In summary:
3,508 HGV (including abnormal loads) movements over 10 months;
and
7,260 cars / light vehicles movements over 10 months.
11.40 As noted in Table 11.2, the predicted traffic movements are not uniform
throughout the construction period. The maximum number of vehicle
movements (1,680) is predicted during month 4. The maximum average
vehicle movements per day (assuming 22 working days per month) would
comprise 76 vehicle movements during months 3 and 4 (of which 36 would
be HGV movements).
11.41 During the construction phase there would be on average a maximum of 8
vehicle movements per hour (of which 4 would be HGV movements).
11.42 Occasionally the site may be worked 6-days per week, which would
reduce the average predicted vehicle movements per day. The maximum
ALV movements would occur in months 7 and 8 and would comprise of 68
movements a month or an average of 3 movements per day.
11.43 As previously indicated, it is anticipated that wind turbine components
would approach from the southbound M18 via Junction 1 to the A631, then
B6060, Hawk Hill Lane and Penny Hill Lane. The majority of other vehicle
movements are expected to approach the site from Junction 31 of the M1
before travelling along the A57, B6463, Common Road and Penny Hill
Lane.
11.44 Tables 11.3 and 11.4 are based on a predicted construction year of 2010
and detail whether the predicted peak traffic increase (76 daily vehicle
movements, 8 hourly vehicle movements) are considered to be significant
or not. The thresholds of significance have been taken from “Guidelines for
Traffic Impact Assessments” (Institution of Highways and Transportation,
1994). Whilst this assessment of the threshold of significance could be
considered outdated it is a useful tool when acting as a guideline to
identify levels of significance in the assessment.
