Traffic Counting
Capturing robust traffic data to better understand on-island transport, monitor modal shift and inform government policy.
Currently only a Guernsey initiative, but we are exploring potential in Jersey.
In order to understand where we are with on-island transport, in 2022, (in Guernsey) we set up a fairly comprehensive traffic monitoring scheme to cover the morning commute to St Peter Port.
We have pairs of volunteers at 6 monitoring stations around St Peter Port who measure all traffic movements between 7h30 and 9h00 on specific days.
At as April 2024 we have built a team of over 50 volunteers in Guernsey who, between them, have logged almost 120,000 journeys with over 6,000 data points on 18 days, so the data is very rich.
Over time, we have monitored traffic to see changes depending upon:
-
Day of the week
-
Season
-
Weather
-
Roadworks
-
School holidays
This allows us to see trends which tell us about commuter habits.
If there was just one KPI for sustainable travel initiatives, it would be changing commuting to have a higher percentage of pedestrians and cyclists and a lower percentage of single occupancy cars.
An example monitoring sheet looks like this:
The traffic counting work is planned and organised by Barrie Deurden and Scott Brehaut.
The latest data published shows that vs 2022 the Guernsey 2024 commute is significantly greener with cars down 4% and both bicycles and pedestrain traffic up 25%. Read about it here.
