Description

The Highways Agency Command and Control database is an incident management system which captures details such as the duration of a carriageway impact. A Carriageway Impact results from any incident where the capacity (of one or more running lanes) has been reduced or where there is deemed to be a risk to a road user such as debris. An impact may or may not result in a full carriageway or motorway closure. A carriageway impact can relate to a single lane that has been closed for a period of time. A carriageway impact is recorded as one impact whether it affects one or both sides of the carriageway i.e. it is not directional. A Carriageway Impact incident includes:- • Incidents upon the HA network not just the TOS patrolled network • Incidents on managed motorway sections even if hard shoulder is not in use • Hard shoulder if being used as live lane during road works. • Any debris in a live lane which should be graded as immediate response • ETM (Emergency Traffic Management) lane or road closures • Minor pieces of debris that pose a risk to say motorcyclists • Rolling road blocks And Excludes:- • Abnormal loads • Congestion – either incident related or not • Reductions in speed due to mandatory speed limits • Planned or scheduled road works • Reduction in speed due to advisory speed limits set by the RCC • Impact on the hard shoulder The information provided is a high level national overview of the number and average duration of carriageway impact incidents and it is a requirement to produce this information, in this format, against the Highways Agency Business Plan measure. Please note only incidents where a carriageway impact has been recorded will be included. Only incidents that occurred on a motorway including Dartford Crossing and some APTR’s classified as a motorway such as A1(M) will be included.
