The statistics refer to the volume of road traffic in Wales. Road traffic estimates for Wales are compiled by the Department for Transport on behalf of the Welsh Government. These estimates are based on annual roadside manual road traffic counts carried out across Wales during the year. These roadside counts are combined with automatic traffic count (ATC) data and road lengths to produce overall traffic estimates. Traffic estimates for major roads are based on a census of all such roads whereas traffic estimates for minor roads are estimated by calculating growth rates from a fixed sample of count points on the minor road network. Further details of the methodology are available from the DfT at the link below: https://www.gov.uk/government/publications/road-traffic-speeds-and-congestion-statistics-guidance . All surfaced roads (excluding Trunk Roads) are included in the estimates. The categories are: Major roads: Motorways. Dual carriageways designed for fast traffic with access limited to motor vehicles, and with relatively few places for joining or leaving. The only motorway in Wales is the M4. A County roads. All other A roads. Estimates for A roads are also available with sub-categories for urban and rural roads on StatsWales. Urban roads are those within the boundaries of settlements with a population of 10,000 or more, and rural roads are all other non-motorway major roads. Minor roads: B roads. Roads intended to connect different areas, and to feed traffic between A roads and smaller roads on the network. Classified unnumbered. Smaller roads intended to connect together unclassified roads with A and B roads, and often linking a housing estate or a village to the rest of the network. Similar to ‘minor roads’ on an Ordnance Survey map and sometimes known unofficially as C roads. Unclassified. Local roads intended for local traffic. The vast majority of roads fall within this category. The analysis by vehicle type is based on roadside observation where vehicles are classified according to their general appearance. The vehicle types identified are: 1) Pedal cycles: Includes all non-motorised cycles, 2) Motorcycles: Two-wheeled motor vehicles, including mopeds, motor scooters and motorcycle combinations, 3) Cars and taxis: Includes estate cars, all light vans with windows to the rear of the driver's seat, passenger vehicles with 9 seats or fewer, three-wheeled cars, motorised-invalid carriages, Land Rovers, Range Rovers and Jeeps. Cars towing caravans or trailers are counted as one vehicle, 4) Buses and coaches: Includes all public service vehicles and works buses other than vehicles with less than 10 seats, 5) Light vans: All goods vehicles up to 3,500kg gross vehicle weight. This includes all car-based vans and those of the next larger carrying-capacity, such as transit vans. Also included are ambulances, pick-ups, milk floats and pedestrian-controlled motor vehicles. Most of this group are delivery vans of one type or another, 6) Goods vehicles: All goods vehicles over 3,500kg gross vehicle weight. Includes tractors (without trailers), road-rollers, box vans and similar large vans. A two-axle motor tractor unit without trailer is also included, 7) All motor vehicles: All vehicles except pedal cycles. Traffic volume is measured using Vehicle Kilometres (VKM), which are calculated by multiplying the annual average daily flow of traffic by the corresponding length of road. For example, 1 vehicle travelling 1 kilometre a day for a year would be 365 VKM over a year. In this release estimates are presented as billion vehicle kilometres (bvk).

The Department for Transport collects traffic data to produce statistics on the level of traffic on roads in Great Britain.

• Summary statistics of road traffic are published on an annual and quarterly basis at https://www.gov.uk/government/collections/road-traffic-statistics
• The most user-friendly method to access street-level road traffic estimates, with an interactive mapping tool, is via https://roadtraffic.dft.gov.uk

Data are available for each junction to junction link on the major road network (motorways and A roads). Data are also available for the sample of points on the minor road network (B, C and unclassified roads) that are counted each year, and these counts are used to produce estimates of traffic growth on minor roads.

The data are produced for every year and are in three formats: a) the raw manual count data collected by trained enumerators; b) Annual Average Daily Flows (AADFs) for count points on major roads and minor roads; and c) traffic figures for local authorities and regions.

An explanatory note (Road traffic data metadata) is available below. A description of how annual road traffic estimates are produced is available at: https://www.gov.uk/government/publications/road-traffic-statistics-guidance

Department for Transport traffic flow data for Sheffield: AADF figures give the number of vehicles that will drive on that stretch of road on an average day of the year. For information on how AADFs are calculated, see the guidance on the Traffic Statistics pages on GOV.UK: https://www.gov.uk/transport-statistics-notes-and-guidance-road-traffic

AADF figures are presented as: Units = vehicles per day.

Traffic count figures from the Department for Transport which give the total volume of traffic on stretches of road in Sheffield for the whole year, and are calculated by multiplying the Annual average daily flow (AADF) by the corresponding length of road and by the number of days in the years.

Traffic figures are presented as: Units = thousand vehicle miles

In December 2023, Amazon.co.uk recorded ***** million visits, up from the previous months. The traffic peak was due to popular end of year sales events and holiday shopping. Browsers and buyers on Amazon during Black Week Amazon’s UK platform was the buzzing with users not just during Black Friday, but on Cyber Monday according to traffic figures from 2018. While there were more Amazon browsers on Cyber Monday, when it came to actual transactions , Black Friday bore better results with more transactions taking place this day. A lucrative market in the UK Amazon gets special attention from UK consumers on special shopping events such as Prime Day and Black Friday, but the UK has been a lucrative market since the online retailer started its operations there in 2002. In 2018, Amazon reported net sales of about ** billion US dollars in this market. This makes the UK Amazon’s second biggest European market after Germany.
