vechicles velocity and density: space / time
Request ID: FOI-2394-1819
Date published: 09 January 2019
I need (for academical reseach purposes) vechicles' velocity and density data from London roads (e.g. 50 cameras), for standard time periods (e.g. every 5 minutes), so that they are connected to car accidents, using spatial correlation methods and testing new analytical approaches. Car accidents' data for the same periods and locations would also be usefull, so that the results are more precise than connecting the velocity, density data, to other time periods. This data is similar to road "status" from api.tfl, but "status" is not enough for this research
TfL Ref: 2394-1819
