The Journey Time data feed provides details on Journey Times , such as location, configuration and dynamic journey time updates.<\/p>\n
The Journey Time data is split across 2 feeds:<\/p>\n
The journey time links listed in the API are managed by either:<\/p>\n
The journey times are derived from Automatic Number Plate Recognition (ANPR) Cameras. These cameras read the Vehicle Registration Mark (VRM) and apply a non reversible algorithm to provide an anonymous Tag for each VRM. Should a Tag for a vehicle be detected at a camera downstream on the link in question, a travel time is then calculated. An average journey time is then worked out for the link using the matched tags for that period.<\/p>\n
It should be noted that this data is not used for speed enforcement purposes and that operators in the UTMC centre have no access to any of the raw VRM data.<\/p>\n
For information regarding the length of the links that are prefixed “Section” please see here<\/a> and for links that are prefixed “CAJT” please see here<\/a>.<\/p>\n There are also two files which give the typical values for journey times on each link, broken down into five minute intervals for both Journey Time Data Weekdays<\/a> and Journey Time Data Weekends<\/a>.<\/p>\n The provision of journey times from the HA and Tyne Tunnel 2 is beyond the control of Tyne and Wear UTMC and can at times be intermittent (especially for the two Tyne Tunnel 2 links). It should also be noted that ANPR systems rely on:<\/p>\n\n
