The need for a new system of traffic signs has long been felt. Government took up the task of developing new traffic signs in 1998. The objectives were to develop a sign system that would: suit the traffic and safety situation in BANGLADESH conform to international conventions be affordable be understood by the public.

7 A special Technical Scrutiny Committee (TSC) was constituted in the Roads and Highways Department (RHD) to supervise the work of developing the new signs. The Committee included representatives of RHD, the BANGLADESH road Transport Authority (BRTA), the Local Government Engineering Department (LGED) and other relevant organisations. The sign proposals were then submitted to the Ministry of Communications for final approval, which was accorded in January 2000. This traffic Signs MANUAL provides the technical guidance needed to ensure that the new signs are designed and placed in a standard way.

8 All road authorities must use the new signs, and all road users must act on the instructions and information they give. With everyone's co-operation the new signs can contribute significantly to smooth and safe travel in BANGLADESH . Mr Syed Rezaul Hayat Secretary, RRD. Ministry of Communications March 2000. traffic Signs MANUAL Page v BANGLADESH road Transport Authority A. Introduction This traffic Signs MANUAL provides technical advice on the design, use, siting and manufacture of traffic signs in BANGLADESH . A traffic sign means any object, device, line or mark on the road whose object is to convey to road users, or any specified class of road user, restrictions, prohibitions, warnings or information, of any description.

9 The term traffic sign therefore includes not only signs on posts, but also road markings, delineators, road studs, traffic signals and other traffic control devices. The signs described in this MANUAL form a new standard set of traffic signs for BANGLADESH . They were chosen following a study of the signs needed for the road and traffic situation in BANGLADESH , both now and in the future. Account was taken of signing practices in the region, as well as the need for the signs to conform to the provisions of the United Nations Convention on road Signs and Signals (the Vienna Convention).

10 Once the new sign system has been in use for several years it will be reviewed, and amended where necessary. For each sign , the MANUAL describes: when to use it what its layout or design should be what size it should be where it should be placed how it should be manufactured and erected The MANUAL is arranged in this general order, with the first parts concerned with the principles governing the use and design of traffic signs, followed by separate sections on each of the major sign groups giving detailed information on every sign . The final sections give advice on the siting, manufacture, installation and maintenance of traffic signs.
