Anyone interested in cycling in traffic should take a look at John Forrester’s website.

He is a Cycling Transportation Engineer who wrote ‘Effective Cycling’ and ‘Bicycle Transportation: A Handbook for Cycling Transportation Engineers’. 

He promotes the idea that "cyclists fare best when they act and are treated as drivers
of vehicles".

He also offers a traffic-cycling course for riders of all ages.  Check out the ‘Effective Cycling’ dvd.
