1.0.15 Upon determining the transport capacity of metro system, the standing passenger standard in effective unoccupied floor area in compartment should be calculated as 5~6 passengers/m2.
1.0.16 The metro vehicle base may be arranged for a line or for several lines according to specific conditions. Where the length of a line exceeds 20km, parking lot may be arranged in proper position according to operation requirements.
1.0.17 Upon designing shallowly-embedded, elevated and ground metro line, measures reducing noise, vibration and impact on ecological environment shall be taken.
1.0.18 Where conditions permit in areas beyond urban center, elevated or ground line should be adopted for metro; the type and size of elevated and ground building structure shall be coordinated with urban landscape and surrounding environment.
1.0.19 Measures resistant to fire, flood, earthquake, windstorm, ice and snow, lightning stroke and etc. shall be taken for metro design.
1.0.20 Safety protection facilities shall be arranged for metro. In addition to those specified in this code, the design of safety protection facilities shall also be reasonably equipped with interface, monitoring system, hazardous article treatment facilities and relevant room, etc.
1.0.21 Barrier-free traveling and using facilities shall be arranged for metro.
1.0.22 As for the underground metro tunnel passing through water areas like river and lake, where the underwater tunnel is damaged and water may jeopardize the safety of other sections on both ends, such ends shall be equipped with flood gate or other anti-flood measures shall be taken.
1.0.23 Mature products meeting the functional requirements and equipped with technical and economic reasonability shall be adopted for metro electromechanical equipment and vehicle; such equipment and vehicle shall also be standardized, serialized, based on domestic production as well as conducive to travel management, passenger transport organization and equipment maintenance.
1.0.24 Measures reducing construction cost and conducive to operation cost saving shall be taken for metro design provided that the safety, reliability and use function of metro are not affected.
1.0.25 Metro design shall not only meet the requirements stipulated in this code, but also comply with those in the current relevant ones of the nation.
