Under the, there is a duty on road authorities and statutory undertakers to co-ordinate their works. This will include programming of temporary traffic management and arrangements for the statutory undertaker’s contractors.

Emergencies dealt with by the public utilities will normally be signed by them, sometimes in conjunction with the police or trafﬁc officers (if appropriate), where the emergency lasts for only a few hours. Where emergency and remedial work is expected to be of longer duration, the Highway Authority or its maintaining agents should be consulted as soon as possible in order to agree to the erection of appropriate signs.

Any special features that may impact on the operational safety of the works will need to be taken into account during the design.

There is likely to be a considerable stock of existing information about the site and this should be gathered and passed to those responsible for the detailed trafﬁc management design (the "design brief" – see Section D2.3) and the trafﬁc management operation, see Part 2: Operations, Section O2.5. Site information could include:


 * information on trafﬁc ﬂows and patterns, peak periods etc.;
 * information on pedestrian usage and usage by other vulnerable road users;
 * availability of alternative routes for diverted trafﬁc;
 * details of any trafﬁc sensitive streets and sites of specific engineering difficulty;
 * details of any railway or tram restrictions;
 * location and nature of permanent signs and road markings;
 * information about existing safety barriers;
 * accident records;
 * the presence of underground and/or overhead services (see HSE Guidance Notes HSG47 and GS6);
 * the presence of rail crossings and other rail signalling equipment which, for example, may affect the location of temporary signals;
 * local weather conditions, e.g. susceptibility to local ﬂooding, fog etc.;
 * safe refuge for vehicles used in association with the temporary trafﬁc management; and
 * needs of local residents and businesses.

The topics listed above are discussed in more detail in Section D3. 15
