1.0.12 Ground and elevated engineering of straddle monorail transit crossing or adjacent to rivers shall be designed according to no less than once-in-a-century flood frequency. As for the underground engineering under waters, flood gate shall be arranged at both ends of underground engineering or other anti-flood measures shall be taken in the case the waters may endanger engineering safety.
1.0.13 Preliminary-stage, short-term and long-term train formation vehicle number shall be determined according to predicted preliminary-stage, short-term and long-term passenger flow, fixed number of staff members or passengers and set train frequency.
1.0.14 Straddle monorail transit depot, stabling yard, main transformer station (high voltage substation) and control center shall be uniformly arranged and share resources with rail transit network.
1.0.15 Surface buildings, e.g. entrances-exits and ventilation pavilions of elevated and ground stations and intervals and underground stations, shall be such designed as to be coordinated with urban landscape and surrounding environment.
1.0.16 Straddle monorail transit shall have as less impact as possible to the surrounding ecological environment. Exhaust gas, waste water and waste discharged from each system shall meet the relevant requirements of the current relevant standards of the Nation.
1.0.17 Vehicles and electromechanical equipment for straddle monorail transit shall be made of mature and reliable products of reasonable technical economy in China, to meet the function requirements and to gradually realize standardization and seriation.
1.0.18 Straddle monorail transit shall be such arranged as to gradually achieve the integrated automation of electromechanical equipment centered on running command and train operation.
1.0.19 Straddle monorail transit shall be equipped with prevention and rescue facilities in case of fire and other disasters.
1.0.20 Straddle monorail transit design shall not only comply with the requirements of this Code but also meet those stipulated in the current relevant standards and codes of the nation.
