1 General Provisions
1.0.1 With a view to maintaining order operation, security, smoothness and low public nuisance of urban road traffic, unifying technical standards of urban road traffic facility design, guiding engineering construction, and achieving comprehensive function of urban road traffic facility, security and practical advanced technology as well as economy and rationality, this code was formulated.
1.0.2 This code is applicable to design of traffic facilities for constructed, renovated and extended roads. Urban road traffic facilities shall include traffic signs, traffic markings, protection facilities, traffic signal lamps, traffic surveillance and control systems, service facilities, road lighting and power transformation and distribution as well as management offices and equipment..
1.0.3 Urban road traffic facility shall be designed according to road nature, environment along the line and traffic flow characteristics; and in addition, it shall meet the requirements of relevant planning, overall design of road and energy conservation and environmental protection in the project location area.
1.0.4 The overall dimensions and load of the design vehicle adopted in the urban road traffic facility design shall meet the requirements of the current national standard "Limits of Dimensions, Axle load and Masses for Road Vehicles" (GB 1589).
1.0.5 The urban road traffic facility shall be designed synchronously with the principal part of the road engineering; and the design is carried out according to the principles of overall design and phased implementation. For the relevant foundation engineering and piping of the principal part of the engineering, they shall be reserved and embedded during implementation of the principal part of the engineering.
1.0.6 The urban road traffic facility design shall meet the requirements of this code as well as those specified in the current national standards.
