London 2012: Businesses 'will cope with Games'
Some 80% of companies in London say they are confident their businesses will be able to cope with travel disruption posed by the Olympics.
Of the 100 companies surveyed, 42% asked staff to change their working hours and 85% of companies that tested home working felt it worked well.
Some 40% encouraged employees to re-route their journeys, however of these, 25% felt it was not effective.
Transport for London (TfL) said businesses needed to make plans now.
Mark Evers, director of Games Transport at TfL, said: "Central London will be transformed into one huge sporting and cultural venue this summer.
"That will have a big impact on both the road and public transport networks so it is vital that businesses, such as those that took part in the Stress Test, take the time now to test their plans and communicate them to their staff, suppliers, customers and visitors."
Mark Naysmith, Games Readiness director at Deloitte which helped to carry out the survey along with TfL, said: "Questions do still remain for the wider business community about whether they are ready or not."
