The traffic generation of a Lidl foodstore is minimal compared to a mainstream food retailer.
As part of the planning application a detailed Transport Assessment has been undertaken to establish the capacity of the surrounding road network and assess the effect of the proposed development.
Lidl have surveyed the key junctions around surrounding the site and will submit a Transport Assessment to Southampton City Council which demonstrates the impact on the surrounding junctions and road network based on forecast trips to the proposed Lidl store. We are still awaiting the results of the assessment, the results will be assessed objectively by Southampton highways authority.
Generally, in terms of traffic generation, the principal effect would be the diversion and transfer of existing shopping trips. Some of these trips will involve both a visit to Lidl and other stores. Others will be simply passing by and dropping in from the A33, The Avenue. Statistical data on convenience shopping trends reveals that very few trips associated with food retail stores are new (typically 20% or less). The majority of the trips (80%) to Lidl would otherwise be on the local road network visiting other locations.
It is important to recognise that discount foodstores stock a mere 1,800 products and have a very low turnover of circa £5m per annum. In contrast, a major supermarket such as Sainsbury’s or Tesco Extra could stock more than 30,000 products and have a turnover of circa £30m. Accordingly, the traffic generation of a discount foodstore is extremely low in comparison.
