To avoid the route becoming a rat run for access to other areas of Cambridge, it is fitted with Automatic Number Plate Recognition cameras to monitor traffic entering and leaving the site without stopping, and the police have power to issue Fixed Penalty Notices to drivers who are not authorised to use the route.
Recently, measures have been taken to slow down the rat run traffic through the village by the installation of bollards designed to inhibit through-traffic mounting the pedestrian footpath.
