A “4 V ertical and 4 Horizontal” fast passenger transportation railway path and three cross-city fast passenger transportation systems will be planned. By then, a total of more than 12,000 kilometers of passenger transportation railway will have been built with the desired speed of passenger train being over 200 kilometers per hour.Being an essential part to railway network, trans stations have already established themselves as comprehensive traffic hubs and modern passenger transportation center on urban and regional levels.1)1) Changsha city is the political, economic, scientific and educational and cultural centre of Hunan Province, the key city in mid-south China region. The Chang-Zhu-Tan economic integration, taking Changsha as the main part and Zhuzhou and Xiangtan as two wings, through continuous exchange and mix together, will be the main core area of economic development of Hunan province. On the ever heating gold travel route of Hengshan, Shaoshan, Changsha.Zhangjiajie, Changsha is located in its center, which is the most important originating and terminating area and gathering and dispersing area of transit of passenger flow in the province. Draw on the experience of development of metropolis and group of big cities in the world, there must be a modernized internationalized infrastructure network and then the developed railway network of big capacity, with high efficiency and environment protection will be no doubt the inevitable selection.2) Changsha Zhuzhou railway hub is connecting four trunk railway lines of Jing~Guang, Zhe~Gan, Xiang~Qian and Shi~Chang, is one of the main railway hubs in central China, and also the main component part of Changsha City communications infrastructure. In accordance with the <Plan of Medium and Long Term Railway Network>, by building Wuhan~Guangzhou Passenger Special Line and Hongzhou~Changsha Passenger Special Line in Changsha,Zhuzhou hub, the layout of “ross type” passenger special lines will be formed gradually within the hub, the regional passenger operation center with Changsha Station and the New Changsha Station as the main passenger stations so as to meet the requirement of increasing passenger volume and improving service quality.2)The New Changsha Station will be located in Lituo Township of Yuehua District in the east of Changsha City, whichis situated in the southeast of the interchangeable flyover of Changsha Avenue and Jingzhu Expressway. It will convergevarious modes of communications of urban rail communications, conventional communications, long distance bus, taxiand vehicles of the community to the hub to form a big scale of comprehensive passenger communications hub. Thescope of conecption design will be the area surrounded by Laodong East Road, Xiangzhang Road, Xin Huahou Road,Zhanqian Road on the east side of Hongqi Road.1)9.5km36.5mThe New Changsha Station will be located in Lituo Township of Yuehua District in the east of city proper, 9.5kmapart from ‘May the First Square’ of Changsha City. It is neighboring new sports city in the west, forest botanical gardenin the south, Mapoling High Technology Agriculture Garden in the north, Jingzhu Expressway runs through on the westside, airport expressway crosses over in the north, round the city line passes through in the south.Apart from part of the land for the residence of village and township people and for some institutions, most of the landis for vegetable gardens, farmland and fish ponds. The land for residents of village and township is in scattered position,the residence for the villagers are mainly of flat house and independent buildings mostly of 1-3 stories.The current instiutions mainly include township firms, offices not bleonging to municipal government and middle andprimary schools. The township firms are mainly building materials factory such as prefabricated parts and warehouses(mainly serving Gaoqiao Market); offices no belonging to municipal government are mainly, village committees andLituo Police Station; presently there are two primary schools of Changtuo Primary School and Lituo Primary School,one middle school of Lituo Middle School. Ground elevation (Hunghai Elevation, similarly hereinafter) is about 36.5m.Site situationZoning analysis9.5km1)1) In accordance wity the Plan of Medium and Long Term Railway Network, by building Wuhan~Guangzhou Passenger Special Line and Hongzhou~ Changsha Passenger Special Line for Changsha Zhuzhou hub, the layout of “cross type” passenger special lines will be formed gradually within the hub. A regional passenger operation center with Changsha Station and the New Changsha Station as the main passenger stations will be formed so as to meet the requirement of increasing passenger volume and improving service quality.2)21024210541.50m2) The New Changsha Station of Passenger Special Line will conduct operations of passenger trains from Wuhan~Guangzhou Passenger Special Line and Hongzhou~Changsha Passenger Special Line. The New Changsha Station will be planned and designed with two rolling-stocks yards, Wu~Guang rolling-stocks yard for the operations of south-north direction Passenger trains and Hu~Kun rolling-stocks yard for the east-west direction Passenger trains resp [ectively. Wu~Guang rolling-stocks yard will be designed with 2 mainlines, 10 arrival and departure tracks, 2 basic platforms and 4 intermediate platforms. Xu~Kun rolling-stocks yard will be a reserved yard, which will be established with 2 mainlines, 10 arrival and departure tracks, 5 intermediate platforms. The reference elevation of rail top in the rolling-stocks yard is 41.505m.3) Dispatching volume of passengers2018240420283591It is forecasted that passenger volume to be dispatched in New Changsha Station will be 24.04 million people in 2018and 35.91 million people in 2028.See the following table for daily peak hour passenger volume for the designed year:2018//The year of 2018 (unit: persons/day, persons/peak hour)Down traffic Up trafficGet on board Get off board Get on board Get off board Daily35945241642991833562Hourly 32352175269323492028//The year of 2028 (unit: persons/day, persons/peak hour)Down traffic Up trafficGet on board Get off board Get on board Get off board Daily 509592680447425 60110Hourly3 458624214268 420820182102028301The New Changsha Station will run 210 pairs of trains in 2018, and 301 pairs of trains in 2028.11Analysis of the transportation condition around1)Relying on Laodong East Road, Xiangzhang Road, Xin Huahou Road, and Hongqi Road which are programmed to be in the adjacent areas, the Station is connected to the outside domain. Xin Huahou Road can be linked with the Jingzhu Expressway which is on the east and the Laodong East Road will be stretched westward to joint the new sports city.2)23The planned urban rail communications network of Changsha City is consisted of Six routes. Urban rail communications Line No.2 and No.3 will pass through the station area in right angle with railway line.Analysis of the transportation conditionsThe Planning Design14Conception of the planning1)I–shaped layoutSince in the plan, Wu~Guang Passenger Special Line and Hu~Kun Passenger Special Line are arranged in parallel and constructed by stage, eventually forming an “I” shape arrangement in the New Changsha Station. Station room is on both sides of the parking lot and in the middle, there is a cross-line waiting room, enabling two parts of the station to connect on the ground floor and the second floor to guarantee that people can pass through freely.2)Green wallTwo large green belts are designed on the both sides of the lines, constituting a ecological “green wall” from south to north. The green wall can reduce the air, noise, vibrating, and visual impact that moving trains may have on the surrounding environment; in the meantime, it can create a comforting, fresh, beautiful environment which is reserved for future utilization.3)Division of people and vehiclesAnalysis of axesThe square in front of the station comprises of two parts: one part is located at the two sides of the bus station on the ground floor, functioning as the assembling square during the Spring Festival traffic peak; the other is composed of the platform on the first floor and the suspended pedestrian path as well. One side connects the entrance hall, while the other spanning the roads in front of the Station and stretching towards the urban green belts on the east and west sides, joining the surrounding hotels and other transportation hubs to open a pedestrian system where pedestrians and vehicles are completely separated. As the eastward and westward pedestrian axial lines, the east pedestrian path candirectly lead to Mopenzhou in Liuyanghe.Analysis of streamline15Function zoning Station room ArchitectureIn the plan, station room is divided into two parts: one is the part that faces the urban roads, including exit, entrance, ticket selling, transferring, office, directing and dispatching sectors, bus station and business services. The other part is the waiting sector which is spanning over the elevated platform. The two parts intersect and combine, presenting an impulsive architectural image and rich interior space.Square in front of the Station and suspendedIn organizing the stream of people, the division of people and vehicles should be implemented as the core principle. The ground floor in front of station room shall function as exit square where taxis and the waiting vehicles could be arranged to wait in order. On the second floor, spaces are provided so that taxis and sending off vehicles to arrive. Platform on the first floor is a pedestrian one, connected to the bus station (on the ground floor), exit, and Square in front of the Station by elevators and stairs. The other ends is linked with the entrance hall, while the other spanning the roads in front of the Station and stretching towards the urban green belts on the east and west sides.Function zoning of site16Second Phase2105Wu-Kun rolling-stocks yard is the second phase. It is under planning and covers 2 mainlines, 10 arrival and departure tracks, and 5 intermediate platforms.Long-distance station zone 1In general urban planning, the long-distance station planned to be located in the west side of Xin Huahou Road at the junction of Laodong East Road which is approximately one kilometer away from the Station to avoid the crowdedness of people and vehicles brought by close range to the train station.Green wallLand use diagramAlong the railways, the north and south sides of station room architecture is planned to be part of the green belt system and a large amount of arbors and bushes will be planted there. The trees which are mainly local species will provide a natural green ecological screening system for the station, reducing the air, noise, vibrating, and visual impact that moving trains may have on the surrounding environment; in the meantime, it can create a comforting, fresh, beautiful environment which is reserved for future utilization.17Traffic planningIn the days to come, the Changsha Station will serve as a modern railway transportation hub which combines multiple transportation modes together to achieve the fast and flexible change among all transportation modes and give full play to the huge importance of the Station in the modern city.In this program, distance-free change mode is the focus. Since elevated platform mode is adopted, so the large space under the rolling-stocks yard can still be applicable. Entrance and exit, waiting place for taxis and picking-up vehicles, accesses to subway parking lots for buses and private vehicles are placed on the ground floor to enable the change among various transportation modes—taxis, private automobiles, buses and subway. The first floor is pedestrian platform whereas the second floor being arriving floor for taxis and sending-off vehicles with which passengers can enter the waiting room without climbing stairs. On each floor, there is elevator, escalator and stairs which function as vertical connection.Division of people and vehiclesA pedestrian system is specially designed on the first floor, enabling the bus passengers to enter and exit by foot without mingling with vehicles. In the meantime, elevator, escalator and stairs will be set up to link other transportation modes, facilitating changes.18Analysis of the main streamlinecEntering streamline2Sending-off vehicles—vehicles and taxis can directly arrive at the second floor, enabling passengers to go inside the cross-line waiting room without going up and down the stairs.Entering streamline of pedestrians—through the platform on the first floor, passengers can pass the railway in front of the Station.Streamline of people entering the subway—subway accesses should be located on the square in front of the Station and within the Station.Streamline of people entering bus station—the bus station is situated right in front of the entrance and exit, enabling passengers to enter the station at ease through the platform on first floor.Self-driving streamline—as to self-driving people, they can park their private park on the social parking lot on the north and south sides and climb to the first floor platform to enter the Station.dExiting streamlineEntering streamlineExiting streamline of people can enter the exits which are on the two sides and in the middle of the Station through a westward and eastward spacious exiting passage.Taxi streamline—a waiting area for taxis will be located on the two sides of the exit square. Bus streamline—When out of the Station, passengers will climb to the passenger area on the first floor by escalator. Private automobile streamline—When driven out of the Station, these automobile can enter the society by going northward and southward. Subway streamline—when exit the Station, passengers can go down to the subway floor through the subway change access on both sides of the exit. Long-distance change—When exit the Station, the stream goes north along the road to long-distance station.Exiting streamline194.Comprehensive economic indexesLand use FormationAreaPlanned total area Area for railway station Area for public square Landscaping area Road area Parking lot area station room building area Floor area ratio Landscaping ratioThe Architectural Design1.Conception of architectural design“Floating yarn Boat shadow”1)Floating yarn48Originated from the “silk gauze” unearthed from Western Han Dynasty at Mawangdui, which weights only 48 grams. Its extreme thickness reflects the supreme weaving skill. “Floating yarn” refers to the awning at platforms. The awning is light and transparent, thus can provide shelter from the sun and in the meantime let in sunlight. It is through the awning that the sunshine spreads on the platform, creating a wonderful fusion of light and shadow. There, people find themselves among an amazing world of light and sound. Viewing from a distance, the inclined load-carrying members assemble a splendid gathering of trees. Once getting of the train, passengers will immediately fall into an vast ocean of light and shadow that feels like silk gauze and it is then the beautiful city Changsha is imprinted on their minds.2)Boat shadowSilk gauze Awning of platform23With the beautiful Xiangjiang River in a distance and the winding Liuyanghe in close range, the land is nourished by rivers in silence. In rivers, one goes fishing and boating, leaving boat shadows behind. In designing the roof on station room, designers echoed the overlapping of boat shadows and waving of lights when boating on rivers. The roof on waiting hall is designed as a mixture of fantasy and reality. With the roof, people can not only be sheltered from wind and rain but also observe the change of time through it. The roof of the whole waiting hall stands on top of the canopy, just like a little boat floating across the water.Liuyang river1.3ScreenBoat shadowAdding a city screen between station room and bus station, the station acquires a messenger board to put out train information, introduction to the city, and commercial advertisements. Meanwhile, the screen can also function as eastward and westward shelter from rain and wind. From exterior to interior space, the Station is then divided into open space, semi-open space, and interior space, providing enhanced space feeling and vision impact.Screen2.Functional plan±0.00Exiting floor plan ±0.00 elevation246.25Entering square floor plan (6.25 elevation)The plan is mainly designed for exiting service to passengers. Therefore, exit passage, picking-up hall, change lounge, luggage hall, technical operation, administration and auxiliary living rooms (dispatch, telecommunication, signal, and electric power, etc.). In addition, access to subway, taxi, bus, and social parking lot are designed to be on this floor as well. a passage in the middle and ticket checking and boarding section on two sides, providing shopping, café, lounge, catering and sanitary fittings. A green passage is designed in the hall to offer fast and convenient direct access to cross-city expresses, laying the foundation for the Station to transform into a “passing station”.The floor plan mainly serves as platform level. Platform is located on one side of the station room, with entering square on the other side. It is a pedestrian floor. In the middle of the station room architecture, there is the entering hall. The ticket selling hall is situated on one side of the entering hall, while the other side being used for commercial, presentation and fast food. VIP lounge and administrative and service room to basic platform is located on one side facing basic platform.The grornd floorThe first floor2516.25Cross-line waiting hall floor plan (16.25 Elevation)3.Flow organizationThe cross-line waiting hall for entering passengers is located on the floor. Passengers can reach the platform on the second floor by vehicle and enter the hall without climbing up stairs. The space inside the hall is open and bright, withTrain stations generally feature large amount of passengers and complicating streams of people and vehicles, thus require rational organization of all streams of people. Passenger transportation station room can mainly be divided into passenger and administrative sections. In the design, administrative part of the Station is opposite to the direction of passengers. The two parts are designed to be independent to avoid interruption. In the meantime, there are passages that connect entering hall and exiting hall to the administrative part to facilitate management.The passengers are composed of entering streamline, exiting streamline and ticketing booking streamline, hence complexion. 1) Entering streamline: Passengers first enter the grand hall through platform on the first floor, and then ascend to the cross-line waiting hall through escalator and elevator. After ticket checking, go down to platforms through suitable passages. 2) Exiting streamline: after exiting, passengers go down to the exiting passage and then leave from exiting hall which is in the middle of the station room and leave by different change modes. 3) Ticket booking streamline: the ticket selling hall is located on the first floor. After buying tickets, passengers can enter the entering grand hall beside.The second floorAnalysis of streamline26Analysis of entering streamlineAnalysis of exiting streamline4.No obstacle design275. Economic indexes of architectures within the StationPeople contented in the station roomHuman beings are highly valued in the design, thus physically-challenged population such as the handicapped and aging are both taken into careful consideration to ensure everyone can move without obstacles.Obstacle-free design is considered in the entrance to station room, parking service area, and service area. The elevators in the Station are designed to be obstacle-free ones with special bottoms and rails for the handicapped and indicating road for the blind on the elevator opening. In public bathrooms, water closets and hand basins for handicapped are designed. In the male bathroom, urinal stall and safety rail are added.Total building area of architectures within the Station Passenger transportation room Auxiliary production and living room Canopy on the platform SubwayParking lotParking space for busParking space for taxi Parking space for social vehiclesThe Structutal Design301.
