What happens when there's a major problem that closes a motorway? Who decides what to do, and how do you resolve things so the road can reopen? And perhaps most importantly for the driver stuck in traffic - why does it take so long?
This article describes the events that might take place following a major incident on a busy motorway. It is loosely based on a real situation, where a tanker carrying gloss paint overturned and spilled its load on the southbound M6 close to Keele Services. It was written for CBRD by "GH", who has extensive experience of dealing with similar events on behalf of the Highways Agency, and gives an idea of what highway maintenance staff must deal with when a serious accident like this one takes place.
The Incident Occurs
An incident can be notified to the Highway Authority by a number of means. It is usually by the Police, it could be by a passing member of the Client or contractor, it could be heard by one of these members of staff on local radio and notified that way. Either way, the first notification goes to the Network Control Centre for that area. Let's assume the call comes from the Police. The Police will call at the earliest opportunity they can find. Police controllers have numerous people to call and deal with, the highway authority are not at the top of the list but are close to the top of it. So, by the time the Network Control Centre are notified the incident could be 20 minutes old.
In that time, queues could be considerable depending on the location and time of day. Initial information from the Police will give the approximate location (it could be that they are still en-route), circumstances, reference number and, if known, what immediate response is required from the highway authority (such as closures, diversions etc). If initial information is lacking in detail, the Network Control Centre will chase up the Police for further information so that they are best equipped to deal with the incident. This can take time, as the Police control room will be stretched at this time to say the least.
