AS TAHMOOR prepares to welcome German supermarket Aldi, the local chamber of commerce has asked for some form of traffic control.

The chamber wants to ease congestion in Remembrance Drive between Larkin Street and Rockford Road after the store opens.

Executive member Jacquelyn Dixon said the chamber was concerned that the additional traffic from the Aldi store would make the turn into Remembrance Drive ``more hazardous than it was now''.

Ms Dixon said Wollondilly Shire Council said road changes had not been considered necessary when the development application was evaluated and approved.

``We dispute this,'' Ms Dixon said.

``We would like to see some form of traffic control introduced that enabled drivers to exit safely to reduce the likelihood of accidents and risk taking.''

Council acting general manager Ally Dench said the council's assessment of the way the Aldi development will affect traffic indicated that the Emmett Street intersection would continue to operate with average delays for all movements of less than 15 seconds per vehicle during peak periods.

``This indicates a good level of service with minimal delays and spare capacity,'' Mrs Dench said. ``It was considered that the overall road network would continue to operate at a good level of safety.''

Ms Dixon said the provision of a safer way for pedestrians to cross Remembrance Drive was an election campaign promise of councillors Robert Khan and Michael Banasik.

``As the DA was not put to the councillors, they were unable to have their say at that time but we are sure that they share our concerns,'' she said. ``Although the chamber has no opinion on whether this should be in the form of traffic lights or a roundabout, we have opened a poll on our website for local people to express their concerns and to register their option. We are happy that Tahmoor is growing and are keen to have the Aldi store in the town but have concerns about the increased traffic it will cause, particularly for that intersection.''

Cr Banasik said he had been pushing for a pedestrian crossing for years.

``Unfortunately the buck doesn't stop with the council; it stops with the RTA,'' he said. ``If the council could put a pedestrian crossing in, we would do it tomorrow, but it's a state road and the RTA won't let us.''

Mrs Dench said the council would still monitor the intersection after the supermarket opened to identify the need for any ongoing improvements.
