A large influx of visitors will inevitably mean that the transport network will be severely affected. To help businesses plan ahead, TfL has set up a website www.london2012.com/traveladviceforbusiness offering a range of tools and advice to help business.

Among the suggestions that TfL is making are staggering the start and finish times of working days, stocking up on non-perishable materials well before the Games, arranging earlier or later deliveries, managing annual leave, temporarily re-locating employees or altering their working hours and helping staff to re-plan their travel.

London 2012 and TfL are arranging a series of events to help businesses start planning. Events are being staged this week for the London Chamber of Commerce and Industry and with Canary Wharf companies, with further sessions planned for later in the year.

London's transport commissioner, Peter Hendy, warned: 'Transport networks will be severely affected. Introducing flexible working hours or arranging for deliveries at different times are some of the options available.'

Visitors to the travel advice website can register for regular email bulletins, view maps of affected areas, download documents to help with transport planning and view hints and tips on creating an action plan.

TfL suggests that organisations with more than 250 employees are also eligible for support from specialist travel advisors. Organisations who think they are eligible can email [email protected] for more information.
