As practices in road construction change over time, it is imperative for Jabatan Kerja Raya (JKR) Public Works Department of Malaysia to continuously update and improve their standard specifications. These new specifications are not only aimed at keeping abreast with current technologies but also helping in improving the quality of constructed product. In uriisOlll these new specifications have a significant positive impacl on the construction industry especially with the incorporation of new products and technologies. Standard Specitication for Road Works is an essential component in the road infrastructure construction industry, This specification provides an improved guidance in the material selection and the production of good quality workmanship and products, based on current best practices. The purpose of this standard spccitication is to establish uniformity in road works to be used by road designers, road authorities, rnanufacturers and suppliers of road related products. This document "Standard Specification for Road Works - Section 8: Traffic Signal System" is a part
of a series of improved specifications in the Standard Specification for Road Works. The compilation of this document was carried out through Illany discussions by the technical committee members. Additionally it has been reviewed by a group of independent consultants and presented at a technical workshop held on 15 - 17 July 2008. Feedbacks and comments received were carefully considered and incorporated in the specification where appropriate.


This Standard Specification for Road Works - Section 8: Traffic Signal System has been prepared by a technical committee consisting of Civil and Electrical engineers from Cawangan Jalan & Geoteknik, Cawangan Kerja Elektrik and State JKRs. The members of the committee involved in preparing this Standard Specification for Road Works - Section 8: Traffic Signal System are
