London Olympic organizers have added an online journey planner and travel pages to the 2012 Games website to give spectators almost a year to plan their trips to the venues.

The planner will allow ticket holders to plot routes by rail, bus, river and London underground from anywhere in Britain. With organizers aiming to eliminate private vehicle use from Games-time travel, the site will also give routes for cycling and walking.

Organizers are promoting advance planning to ease the expected congestion on London's transport network.

London organizing committee chairman Sebastian Coe says "getting spectators to events on time and back home again is going to make a huge difference to how people remember the Games in years to come."
