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.
