~5 mile commute, from memory, including peccilans, from memory:
Peccilan on High St.
Lights at RT to Colhams Lane
Lights on Coldhams lane by new business park
Peccilan on Coldhams lane just after Sainsburys roundabout
Peccilan further down Coldhams lane
Lights at Cromwell Road/Coldhams lane junction
Toucan on joining Newmarket Rd after crossing Coldhams Common
Peccilan on Green End rd
Lights at Milton Road/Green End Rd junction
Peccilan on Kings Hedges Rd
Lights at end of the commute are bypassed by crossing the disused railway, but this is turning into a Misguided Busway so that will probably add a set of lights.
10 in 5 miles.
If I go the cyclepath (slightly longer) route, more pleasant because Coldhams Lane is an arse to cycle down, then it's 3xPeccilan, one x lights in ~5.5 miles, so less than one a mile.
Can you tell I don't live in London?
