1. Introduction
1.1 This report outlines the results of traffic surveys carried out to monitor the effects of the recently opened A43 (T) Silverstone Bypass. The scheme provides an improved route for through traffic using the A43 between Brackley and Towcester, in Northamptonshire. It forms part of the M40 - A5 Dualling Scheme, providing a continuous dual carriageway between the M40 and A5. The A43 (T) Silverstone scheme replaces the old single carriageway road and comprises two bypass sections around the villages of Silverstone and Syresham, as illustrated in Figure 1.1.
1.2 The A43 (T) Silverstone Bypass was officially opened on the 18th September 2002, although was opened as a single carriageway in early September. The scheme was partially open in July 2002 for the British Grand Prix as part of the network traffic management plan routeing spectator traffic to and from the race circuit. "Before" and "After" traffic data for the bypass was collected immediately prior to and after the September opening date in order to prepare a Traffic Impact Study (TIS) on the effects of the scheme opening. In addition, traffic data from Northamptonshire County and Highways Agency count sites has been used to evaluate the effects of the opening of the A43 (T) Silverstone Bypass on strategic traffic routeing patterns in the area.
1.3 Chapter 2 of this report discusses the data collected as part of the TIS study. Chapters 3 and 4 summarise the main results and conclusions.
