2.2.5 It is helpful for authorities to contribute local safety data to the MOLASSES project. This project, initiated by the County Surveyors�Society (CSS), is able to assess different treatments in relation to specific accident problems. The aim is to give individual authorities a better idea of the effectiveness of different types of scheme. The traffic calming measures used in the plans can be evaluated by following the procedures given in the RoSPA manual (2002). Progress reports of the MOLASSES project has been produced (Mackie, 1997; Gorell & Tootill, 2001). The web site (www.trl.co.uk/molasses) dedicated to MOLASSES enables local authorities to submit information and queries.2.4 Consultation Initial consultation2.4.1 Highway Authorities have a statutory duty to consult the police (Highways Act 1980) when road hump schemes are proposed for a road or area (TAL 03/94) and they must also post notices in the street and in local papers advertising the scheme. The 1999 Highways (Road Hump) Regulations require consultation with the fire service, ambulance service and organisations representing those who use the road. This would include the residents�organisations and the bus operators, but it may also include haulage or agricultural organisations in certain areas. It is also recommended that the consultation process does not just cover the statutory duties requirements, but that authorities should open up a dialogue with all interested parties (including pedestrians, disabled people, cyclists�groups and, where appropriate, equestrians) to try to ensure that there is a consensus in favour of the scheme. For disabled people see Laria guidance (www.laria.gov.uk). 2.4.2 In recent years, the London Ambulance Service has raised concerns that traffic calming may have a detrimental effect on ambulance response times. A regular dialogue has been established to determine the nature of their concerns and assist with possible solutions. 2.4.3 As a result, the Department has revised its Traffic Advisory Leaflet Fire and Ambulance Services - Traffic Calming: A Code of Practice (TAL 1/07). The revised leaflet re-emphasises the need for local authorities to establish at an early stage of scheme design a meaningful dialogue with the emergency services affected by the schemes. 2.4.4 Highway authorities also have a statutory duty to consult the police when traffic calming (other than road humps) measures are proposed under the Highways (Traffic Calming) Regulations 1999. The authority must also consult organisations or groups who use the road or others who are likely to be affected by the traffic calming work. Whilst these regulations are less prescriptive than the hump regulations, it is suggested that authorities may use the same overall consultation procedure as for road humps for all traffic calming schemes.2.3 Use of traffic calming for security purposes (e.g. anti-terrorism)2.3.1 Amendments to the Highways Act 1980 and Roads (Scotland) Act 1984 (traffic calming works regulations) made by the Civil Contingencies Act 2004 (part 3, schedule 2) now enable local authorities to introduce traffic calming for the purposes of slowing down traffic in the vicinity of potentially vulnerable or sensitive sites where a security threat has been identified. The blend of any (preferably self-enforcing) traffic calming and vehicle restraint measures (bollards, blockers etc) can better manage the risk from penetrative attacks by hostile vehicles (vehicle bombs etc). Vehicle restraint measures can be less substantial (and therefore typically more aesthetically pleasing) if the speed of approaching hostile vehicles is reduced. Traffic calming and restraint measures may accompany new traffic regulation measures introduced either temporarily or permanently through Anti-Terrorist Traffic Regulation Orders (ATTROs). 2.3.2 ATTROs are made using sections 22C or 22D of the Road Traffic Regulation Act 1984 as amended by the Civil Contingencies Act 2004 (part 3, schedule 2, part 3). ATTROs should typically be used sparingly and only when prompted by the direct involvement of the local police Counter Terrorism Security Advisor (CTSA) and highways or traffic experts from the National Security Advice Centre (NSAC) whose contact details are available through the Traffic Management Division of the DfT. A list of crash-tested products and systems for such security uses is available from the same experts, along with advice on the implementation of any such measures.14Traffic Calming
