1.0.10 Train number of each group in preliminary, short-term and long-term stages shall be determined according to forecasted passenger flow volume, allowable passenger number of train and designed density of train flow separately.
Allowable passenger number of train shall be the total number of seat number on train and number of passengers who stand in train. Allowable passenger number at free area in train shall be 6/m2.
1.0.11 Subway depot shall be designed according to line network planning. According to concrete conditions, one depot can be set on each line or one depot can be shared by several lines.
Where length of one line exceeds 20km, extra stabling yard can be set at appropriate places according to operation requirements.
1.0.12 Convenient travel change shall be adopted at crosses among subway lines and other rail transit lines.
Travel change between subway lines and other general ground traffic lines is recommended to consider uniform planning.
1.0.13 During the design of shallowly-embedded and overhead ground lines, proper measures shall be adopted to reduce noise and vibration and to avoid influence on biological environment, and shall comply with emission provisions of applicable national standards.
The emission, sewage and solid waste discharged from the subway system shall meet the relevant discharge standards of the nation.
1.0.14 Determination of modes and quantity of ground and overhead subway devices shall consider influences on urban landscape and coordination with ambient environments.
1.0.15 Earthquake protection intensity shall be determined according to earthquake safety evaluation approved by competent authorities of local government.
1.0.16 Ground and overhead subway engineering crossing and adjacent to rivers shall be designed according to 1/100 flood frequency standard.
Subway engineering crossing rivers and lakes shall have flood-proof gate or adopt other flood-proof measures at appropriate positions at ends of relevant water area.
1.0.17 Subway design shall gradually realize electromechanical equipment integrated automation centralized on train travel direction and train operation.
1.0.18 Selection of subway electromechanical equipments and trains shall consider standardization and series, and China-made equipments are recommended to be adopted.
1.0.19 During subway design, measures shall be adopted to reduce engineering cost and operation cost, but subway safety, reliability and adaptability shall not be affected.
1.0.20 In addition to provisions prescribed herein, subway design shall also comply with relevant provisions of applicable national compulsive standards.
