15 smart sensors were 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.

Data will be released monthly for these locations until the end of 2020. Please note that due to the level of insight that can be gained from these sensors, additional sensors in more locations have been installed in Cambridge since the summer of 2019. Some sensors will remain beyond 2020 in strategic locations and the network is expected to grow. Data for those more permanent sites, outside of the Mill Road project will be published here: https://data.cambridgeshireinsight.org.uk/dataset/cambridge-city-smart-s...

Mill Road Bridge was closed for eight weeks from 1 July 2019 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.

A high concentration of sensors were installed for approximately 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. This has allowed engineers to see the impact of the closure on surrounding roads, including on air quality. Keeping the sensors in place for this long has also allowed teams to make greater comparisons, by taking in to account daily, weekly, monthly and annual variations in traffic levels.

The below data release offers counts for each sensor over 1 hour periods. The curent data covers the period 03/06/2019 to 13/12/2020.

Hourly counts are broken down by inbound and outbound journeys. .

Counts are also broken down by vehicle 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.
