Be careful to check what the "type approved" equipment is approved for. It is important to distinguish between "temporary" and "portable" signals. They are defined in TA 84 temporary signal: A traffic signal using the same type of signal equipment as permanent signals but which is installed for a limited period of time (e.g signals in barrels) portable signal: A traffic signal designed to be moved from place to place. Pedestrian signals may be included in "temporary" signals installations because they are governed by the same regulations as permanent signals. Pedestrian signals are not permitted at "portable" signal installations. The control equipment may be approved as a portable traffic signal controller but this does not include approval for use with pedestrian aspects. Andrew Hancock says: The actual brochure for the product says that it is fully compliant with TR 2503 "Performance Specification for Pedestrian Facilities at Temporary Stand-alone Traffic Signals". TR 2503 allows such things as radio linking and battery power but it still refers to "temporary" not "portable signals". The signals are required to comply with the regulations for permanent signals in physical appearance and layout (TSRGD Regulation 33). There are also requirements not normally found in portable signal equipment such as SA/SDE capability. Claiming compliance with this specification is not the same as being Type Approved. Anyone can check the Type Approval status of any equipment at www.tssplansregistry.org. (You will need to register to get access). This gives acces to the list of Type Approvals MCS 215. There are currently no approvals issued against TR 2503.

This is taken from LTN 1/98 "The Installation of Traffic Signals and Associ= ated Equipment": 8.09 Care should be taken to safeguard pedestrian safety during roadworks within the area of the work site and particularly at or near pedestrian =20 crossing facilities. Temporary pedestrian facilities may be provid= ed on temporary signals as long as the area where pedestrians should cross is clearly marked. This suggests that pedestrian facilities could be used at temporary signals when working near a pedestrian crossing which has to be switched off. The actual brochure for the product says that it is fully compliant with TR= 2503 "Performance Specification for Pedestrian Facilities at Temporary Stand-alone Traffic Signals". (This=20can be found at the TSS pla= ns registry website: http://www.tssplansregistry.org ) This specification states that the product should comply with TSRGD Diagram 3000, Regulation 33, the signals shall comply with TSRGD Diagram 4002.1, Regulation 47, and=20the push button shall comply with TSRGD Diagram 4003= and Regulation 47. The unit uses peak elite signal heads and AGD push button units all of which are fully compliant with the TSRGD regulations. With regards to approval for the product as a whole,=20this comes under the requirements for Self-Certification set out in TRG 0600 (http://www. tssplansregistry.org) which allows companies to design, test and self certi= fy a product to a specific Technical Requirements Specification. This specificat= ion also gives regulations that it must be compliant with when using radio sign= als. Again in the brochure this is something that the company states the equipme= nt fully complies with and so I believe the product could legally be placed on= the highway with no site specific authorisation being required. The one thing that would be of interest is how drivers react to the signals. Drivers tend not to treat temporary signals with the same respect as perman= ent ones and so when they see the other side stop they may drive through the red signal which would create a major safety issue. ----------------------------------------------------------- A message from the TCUG mailing list.
