Table 8: Analysis of the TRICS database

For example, the factor for arrivals at an office building (A in column 1 of Table 8) between
8.00 and 9.00am is shown as 2.171 meaning that for a building of EDF’s size 66 vehicles
would arrive. For peak hour departures from a block of 71 residential flats a factor of 0.241
was calculated suggesting that 17 vehicles would depart and in the case of 120 flats, only 29
vehicles would head out.

The TRICS calculations imply that 300 employees worked in the EDF building whereas
the company states the maximum was 200, usually on shifts.

In Ashurst Wood, between 58% and 70% of the population is employed with around 13%
on pensions. There is very little local employment or public transport, so people drive to
work. The average car ownership is estimated at 1.6 per household with an average of over
2 residents per dwelling.
Thus, for a block of 71 flats in Ashurst Wood common sense suggest an outward morning
traffic flow of at least 35 vehicles and more likely 75: rather than the 26 calculated by TRICS
(see Figure 14 page 27).

The TRICS Best Practice Guidance sets out how calculations should be made, and an
audit trail retained. This was not followed in the Transport Report.
