Traffic Survey

Big Data released from Cambridge vehicle survey 

Preliminary ‘big data’ from an eight-day study of millions of vehicle movements traveling in Cambridge has been published by the Greater Cambridge Partnership today <21 November 2017>. 

The anonymised data, capturing information on vehicle movements in, out and through the city, has been made available as ‘open data’ - allowing public access and the chance to suggest innovative transport solutions.

It follows some initial findings published earlier this month, which showed that over five million vehicle journeys were captured in a single week and over half of the cars recorded (56%) were diesel and contributing to the city’s pollution levels. 

This initial data, published on Cambridgeshire Insight, provides origin and destination and trip chain reports derived from the traffic survey using Automatic Number Plate Recognition (ANPR) cameras undertaken across the Cambridge area from 10 - 17 June 2017. 

The remainder of the vast dataset is currently being reviewed to ensure that no vehicle is identifiable and the data remains fully anonymous. It is envisaged that the full dataset from the traffic survey will be published in early 2018. 

The ANPR survey was undertaken to provide additional and up-to-date information on the city’s road network to help inform the development of transport schemes.

Chair of the Greater Cambridge Partnership, said: “We are pleased that we can release some initial data into the public domain, so residents and other interested parties are able to undertake their own analysis and participate in the ongoing development of the city’s future transport provision.

“A traffic survey of this scale has never been done before in Cambridge so we’re proud to be achieving another first for our great city. The sheer volume of data means it’s taking some time to review and we need to ensure its anonymity and accuracy.”

The origin and destination reports published provide information on the first and last cameras triggered on vehicle journeys across the city. The trip chain reports provide additional detail, giving the camera survey sites triggered along vehicle routes across the network. 

The Greater Cambridge Partnership has a number of upcoming events on tackling some of the city’s transport issues, including a Wayfinding Hackathon on 25 November, workshop for staff and visitors to Addenbrooke’s Hospital on 28 November, followed by a Cambridge Network Future Transport Event on 30 November.

Please note that the maximum trip chain duration within the reports is two hours, and that vehicles travelling ‘outbound’ past an external camera site will end that particular trip chain. The ‘Taxi’ classification includes only Hackney Carriages.
