2009 I obtained agreement on behalf of Southwark Council from TfL that for the cycle super highway along Southwark Bridge Road (most of its route in Southwark) that it would be 20mph.
Putting self enforcing measures along the road would be really expensive and disruptive.
Separately I’ve been nagging Southwark Labour cabinet members about trialling 20mph average speed cameras.
I’m chuffed to see both moving forward: http://moderngov.southwark.gov.uk/documents/s38028/Report%20-%20Allocation%20of%20discretionary%20funding.pdf
20mph average speed cameras will also have a small £10,000 study about them being applied to Southwark Bridge Road.
I submitted details to them about Siemens having a self funding scheme with 3-4 speeders paying to attend speed awareness courses and some of the fees paid for the £50,000 per cameras pairs and administration.
Hopefully the study concludes this route is suitable. Happy days for an opposition councillor to helps steer an administration policies.
