COMMUTERS could take to the water to escape congestion if an investigation into river travel proves a success.

In a bid to take the strain off the capital's trains, tubes and buses the London Assembly is looking at the potential of increasing the number of commuter services on the Thames.

Currently there are 10 services running between Putney and Woolwich each day which were used by 500,000 commuters in the past 12 months.

The investigation will look at the river's current services, including cost and frequency, and how the service could be used during the 2012 London Olympics.

Investigation conductor, assembly member for transport Angie Bray said: "The Thames is one of London's best assets.

"Londoners get on with their lives unaware of its potential."

Results of the investigation are expected in September.

The findings will be given to Transport for London for a decision in consultation with local authorities and private developers.
