Answer for Tolworth Roundabout, A3

Answered By: 
Peter Hendy (Commissioner, Transport for London)

Initial estimates provided by the developer's transport consultants forecast two-way vehicle trips of:

· 400 in the AM peak (Friday 0800-0900); · 988 in the PM peak (Friday 1700-1800); and · 850 in the weekend peak (Saturday 1300-1400)

TfL has reviewed the Transport Assessment and will be requesting additional information to support these forecasts.

As one-way access arrangements are proposed, all of these trips would have to use the section of the Tolworth Interchange roundabout that connects Kingston Road to the development and the southbound on-slip to the A3 Kingston Bypass. Of these trips:

· 41% will use the A3 south of the roundabout · 15% will use the A3 to the north · 22% will use Tolworth Broadway · 22% will use Kingston Road

These figures apply to traffic both arriving and departing. We are awaiting additional information from the developer in order to be able to assess the impact on the highway network.

The developer has also submitted proposals to increase the capacity of the roundabout and the Kingston Road approach to accommodate this additional traffic. We are reviewing these proposals and again require additional information in order to be able to assess them adequately.
