There are a total 4,552 road traffic signs on the A90 trunk road network. Of these, a total of 185 signs do not meet the current standards for visibility and effectiveness and are on a works programme for future replacement. Where regulatory signage and warning signage are noted as defective they are categorised as Category 1 defects. These are required to be made safe when identified, following which a temporary or permanent repair must be undertaken as soon as possible and no later than 24 hours following first identification. Where possible, Category 2 sign replacement is coordinated with other works on the network to mitigate disruption to road users.

There have been no official complaints logged regarding the overall condition of the A90 in the last five years. However, there has been a total of 171 individual complaints with resulting reports:

Transport Scotland conducts machine-based surveys using specialist vehicles each year to gather information on the surface integrity of the road; the friction characteristics of the surface; and the structural capacity (strength) of the underlying road construction. The data obtained provides an annual snapshot of the road condition across the network and is used to determine a Road Condition Index for each section of road. The Index values can then be used to identify where detailed engineering investigations should be focused in order to determine maintenance requirements.

The proportion of the A90 that has been assessed as requiring further preliminary investigation to determine whether structural maintenance is required is currently 18%. This compares with 17% across the whole of the trunk road network.

Fleet carbon emissions are published in our Public Bodies Climate Change report which is available on the Scottish Sustainability Network site. Additionally, SG holds the Carbon Trust to Net Zero Standard for year on year carbon reduction, with carbon emission data on the fleet independently audited by the Carbon Trust to ensure accuracy.

A breakdown of fleet additions and disposals since 2019-20, broken down by vehicle and fuel type, is provided in the following tables.

Pool cars are allocated to specific areas who have a business need for their use which cannot be met by public transport or other sustainable methods of travel. This includes conducting legislative and compliance inspections, animal and horticulture inspections, delivery of equipment and the transportation of Ministers.
