More guided busways for Cambridge?

Cambridgeshire County Council is considering creating a new stretch of guided busway ( or possibly dedicated bus-only lanes) in Newmarket Road, Cambridge. See report in The Cambridge News http://www.cambridge-news.co.uk/Home/Guided-busway-could-be-extended-into-central-Cambridge-24052012.htm and also in the Huntingdon & St Ives News & Crier (31 May (page 17). This is an attempt to deal with existing traffic congestion plus extra traffic that will arise if a new development of 25,000 houses materialises.
