TEMPORARY TRAFFIC CONTROL DEVICES

Transcription

1 706.1 GENERAL B OPSS 706 Temporary traffic control devices are used for guidance, information, and to control the flow of traffic during construction. Temporary traffic control devices include the following: Temporary Traffic Control Signs Road Closing/Restriction Notice Sign (TC-64) Automated Flagger Assistance Devices (AFAD) Portable Variable Message Sign (PVMS) Temporary Traffic Control Signs Temporary traffic control signs are all traffic control signs and associated devices identified in OTM Book 7, including vehicles and sign trailers required to support signs and equipment to supply sign lighting; but excludes highway number markers. Contract Information Signs A contract information sign is a sign installed to inform motorists of the type of construction work taking place. There are two types of contract information signs: a TC-81 sign and an Owner supplied contract information sign. Road Closing/Restriction Notice Sign (TC-64) A road closing/restriction notice sign (TC-64) is a sign installed to provide advance notice of a road or exit ramp which is to be closed or restricted. Automated Flagger Assistance Devices (AFAD) Automated fflagger assistance devices (AFAD) are self-contained, portable traffic control systems where the signal and/or control arm are operated remotely by a traffic control person (TCP). Portable Variable Message Sign (PVMS) A portable variable message sign (PVMS) is a traffic control device that is capable of displaying digital messages. PVMS are used in work zones to provide road users with advance information of work operations which are outside their expectations such as closures or speed reductions. PVMS should be used for situations where conditions are changing and are in addition to Temporary Traffic Control Signs required by the Ontario Traffic Manual. February 2017 Page 1 of 12 B706
