There is a new survey on travel options around Greater Cambridgeshire here:
www.smartsurvey.co.uk/s/Greater-Cambridge-Travel-Survey-2017/
the blurb says:
The Greater Cambridge Partnership (GCP) have commissioned Travel for Cambridgeshire (TfC) to deliver a transport survey targeting residents, students and commuters in and around the Greater Cambridge area to help them better understand your travel needs and inform a future investment strategy in the local transport network.
This is an opportunity for YOU to have YOUR say and influence the decisions that will transform transport in Cambridge for many years to come.
Of course - as usual they don't seem to recognise that it's often not possible to replace car journeys with other transport (eg across/round Cambridge, with lots of children etc).
