    Section

    The purpose of this Technical Note is to provide Elected Members with additional information about the average speed camera system installed on Auchinairn Road, Bishopbriggs.

    Background

    A previous Technical Note (Average Speed Cameras, Auchinairn Road, Bishopbriggs 15/02/2021) provided some background information into the decision to install average speed cameras on Auchinairn Road. Following a question asked at Council, additional information is provided here.

    Between 2013 and 2017, one serious and 10 slight collisions were recorded in a 1km stretch of Auchinairn Road with a cluster near Clelland Avenue. The serious collision was on a pedestrian crossing facility. During this time, average speed was measured at 33.7 mph and the free flow 85th percentile speed was 39.4 mph. This is a 30 mph road with average daily traffic of 13,435 vehicles, of which 78.5% were travelling above the speed limit.

    Auchinairn Road is long, narrow, straight single carriageway road with not much frontaging, but with shops on both sides at points. The footways near Clelland Avenue are quite narrow and a fixed camera would restrict pedestrian movement. There is no opportunity for mobile camera enforcement. Because speed is a factor in the collisions, one took place on the pedestrian crossing and because of the volume of traffic, the Safety Camera Unit recommend the site for average speed cameras.

    Safety Cameras Scotland will monitor the site annually for as long as speeds remain high. If speeds reduce, and with the approval of Council Officers and Police Scotland, there is a gradual process to decommission the site without encouraging speed to increase.
