15 smart sensors have been installed on Mill Road and surrounding streets to record numbers of pedestrians, bicycles, cars and other vehicles. The data being collated and analysed by the Smart Cambridge programme will help the Greater Cambridge Partnership understand how people use the road network.

Mill Road Bridge will be closed to vehicles for eight weeks from 1 July for crucial work being carried out to improve rail services. Pedestrians and cyclists will still be able to cross the railway for most of the working time.

The sensors will be in place for at least 18 months to gather data before the closure, during the time when there is no vehicle traffic coming over Mill Road Bridge and then after the bridge is re-opened; allowing engineers to see the impact of the closure on surrounding roads, including on air quality. Keeping the sensors in place for this long will allow the team to make greater comparisons, by taking in to account daily, weekly, monthly and annual variations in traffic levels.

As part of this trial, 8 Air Quality monitoring devices have also been installed and this data is now also being released via Cambridgehire Insight Open Data.

The below data release offers counts for each sensor over 1 hour periods. The curent data covers the period 03/06/2019 to 30/06/2020 but  updates will be appended to the existing data release every two weeks during the period of the bridge closure and monthly after that.

Hourly counts are broken down by inbound and outbound journeys. The data can be  broken down by inbound and outbound journeys.

Counts are also broken down by journey type. This includes:

• Pedestrians
• Cyclists
• Buses
• LGV
• OGV 1
• OGV 2

The release also includes a full list of sensor sites with geographic point location data.
