At a city an accessible public transitional area nrovide the most intense of city image as any door leaners will testify. Kevin lynch said : "Those important exterior and interior soace that are exnlicity accessible to general oublic and frequency used by them the main street but also the central area............. The charac-
ter of these elements and their connection as a systerm can be analyed at the regrnal scale."1 Taipei Station area, which located at the central downtown area, is such a public transitional area of Taioei city. It will provide a new urban environment to the city.
Thr-ee- most directly effected nieces of this urban environment have been land use, urban snace and trans-nortation, which are weak today. This thesis will deal with the reinforcement of those urban function and exploring ways new develnment can draw from old city structure and environment. My thesis project, a transit center square renewal, is such that land use urban snace, transportation and existing historic buildings are the critical issue.

The city is understand only in Imagination. Didersity is the mental image of a city. As Jane Jacobs said:
"........cities are natural
generator of diversity.......a
mixture of use needs an enorm-
ous diversity of ingredients." Since Taipei Station square is such a imnortant transitional area, it should be a "mincity" whibh rro-vide the first image and diversity urban function to the public. And because "for the understanding of city, we have to deal outright with combination or mixtures of uses, not
senerated use as the essential phe-
It means a integated frame work in which activities of citizen and economic are allowable.
Open space is the major element of urban space. Taipei Station plaza used to be the most important open space of Taipei city, where allowed people trail, gather, transfer.
Today, it is crowded with vehicle and forgot how the open space enrich human life. I wish to receate the
missing quality ---- a open space
which is belong to citizen, not belong-to vehicle.
Circulation is the natural function of Taipei Transit center. Fecause of it's important location, this area

should be.a central core for the whole City. The public transoortation will all get gather to here and disperse from here. For this reason, a clear sys-term for velhicle and pedestrian is necessarily established. This system applies to the oarticular value site is vertical seoeration system.
Because of it is a critical respond to the urban renewal, because it
is in Taipei station area --- a unique
historic area and where so much has been destroyed necessarily confronts the issues of History and Historism to the renewal. Historism is the most arbitary use of history. In my thesis,
I neither attemp to go back with imitation past or to use all the historical Pieces of architectural like.
I want to establish a more dillectial relationship between the modern oeriod and his toric period.
For the understanding through a structral reading, of the difference between the new urban structure and old urban environment, this area should be componsed by historic buildings and new structure, and to tran-form the old structure into new structure with linking different grids and orientation of historic buildings.
Therefore, the idea for the new and old buildings is "combination".

Taipei Station Square renewal
It was in its early history, the fortress wall of ancient Tainei was builtalong the north and east edge of the downtown area, that is precisely the location of today's railroad, and most of the north part is occupied by the Taipei Railroad Station. Because of its exis-tance the site is presently characterized by a somewhat disconnected and discontinuous pattern of use. Particularly, it causes wild break in the continuity of the north-south traffic of this area, downtown frame uses, and additionally reduces the potential for an invisiting urban quality, thus inhibit development.
Therefore, the rainitry of communicate begin to develop a rapid transit system to solve those problems. The first proposal was approved in 1981 and the whole project will be finished in six years.
In this project, the existing track was combined with rapid transit system at 27 feet below ground level was provided for further delvelopment. It is anticipated that when this projected transit system is built, it will increases the values of land

use and.the site which at nresent confused and of poor quality will become highly attrative.
My thesis, the Taipei Station Square renewal, is to deal with the development of the land use urban form and function for this Dotential si te.

The thesis is a mixed-use' urban renewal. The location and importance of the site make it much more than that. The city was once very active around. With the increaseing of passengers cars and with the physical separtion of it from the city by the highway and cars, the Taipei station square gradually loose it's function and urban core image. Any efforts to develop have not made the economic and social impact necessary to make it a vibrant, populous part of the city. Government of Taiwan R. 0. C. finally decide to reinforce it's land value and function by adaption to the new Taipei metro-rapid transit systerm. This thesis will be an effort to renew the Taipei station square after the existing railroad moveing to 45' feet underground. I will try to reform the importance and city core image that has all but died, to transform it into a "place" which is belong to citizen and to return the important to the city.


1. Analysis Method :
Three critical issue in ana-lizing the develpment of situation of Taipei station are :
(1) culture background : History, social affector.
(2) function background : Urban develpment orocess.
(3) environment background : Fhsical characterisic of urban snace.
The reason for using this kind of analysis is to review the develp--ment of each urban snace and mass in order to understand the traditional situation and image of study area so that to figure out the outlay of future develpment.
2. The' History Of Taipei Station :
(1)Develpment :
* 1887,The train drive from Taipei to Gi-long,1891 extent to Shi-chu Taipei Station then was located beyond Cho-shing hospital.
* 1905, Station was moved to existing uosition.
* 1908, The track was extent from North Taiwan to South Taiwan.
* Because of the increasing
of nonulation and gargo, established Hau-San Station is established to share the pressure in 1937.

* 1938 renew the old Taipei Station.
* 1951 Taipei Station become a major passenger's station, subway station union and head'-quarter offices were built beside railroad station Prom then on, Taipei Station become the transit center till now.
(2) Function and Image :
a. A transimission snace :
Located among local retail area (north bound), commerical office area (east bound), contral Business District (Southern-west),and public culture centeral area.
b. A transit hub and gate way of old Tainei city :
North Gate, West Gate and South Gate were the main "door" which connected inside and outside of city.
The establishment of train station and bus station made this area become a transit hub.
C.Indicates the traditional axis and orientation of Taipei city (figure ).
d.A historic area :
Taipei Station Area was the linking area of earier clusters and public facilities. Also because of the long history of this area, it contents many historic buildings

which were the part of city.
3. Suggestion :
(1) Maintain, the original supper block, so that to keep the urban structure and local unique character.
(2) Link the historic image to new buildings,landmark and urban space.
(3) Create a pleasure urban space which allowed public gathering and reform the function of city "door".

1. Net work : (figure )
Railroad and station cut down the net work, the street systerm is confused and crowded.
(1)East 4:----> West
Nanking W. Rd., Chang An W. Rd. and Chung Hsiao W. Rd. are the major streets. Chung Hsiao W. Rd. is the most serious traffic in peak hour.
'(2)North 4---> South
Chung Shan S. Rd., and Huan-hos. Rd. are the major circulation lines. Huan-ho S. Rd. is a perimeter road, there is short of link with the local street. Chung-Shan S. Rd. is a left-turn limited line. Cars come from freeway, pass trough Chung-Ching N. Rd. (a turn-nike) then up 'Torth-gate high way to Southbound of the city. Therefore North-gate intersection. (Southern-west corner of study area) become a traffic bottle neck.
This intersection is the most crowd corner in the whole city's, (figure )

In order to define the function and farget of mysite. I enlarge the study area and try to define the situ-lation of ray site by analyzing the whole central city area. therefore T review the develpment and existing land use (chanter 2), and establish the tendency of essential develoment (chap. 3), then to define the basic target of this project (chan. 4). The tendency of future develoment are :
(1) A diverse urban core :
Because the unique character of this site (see chap. 2,figure ),
it will still be the best position for urban core and transit hub.
(2) Link the structure of Taipei city :
This site is a transimission area of several different land use zone, snd which indicate the urban structure and orientation.
(3) A new Gate-way of Taioei city :
This area used to be a gate way of Taioei city, and it will still on the same the urban future.
(4) To establish an open space which is connected to the western planning park systerm and River. The open space will provide a place for gathering, dispersion and transfer.
(5) To privde a aboundant historic image of old Taipei city.
(6) To privde a clear sky line of modern city.


Ease on essential develpment of study area (chapter 3) and consider the pratical to define the target of
(1) land use (2) circulation (3) environment quality, then summarize the orincple of fature develpment.
1. Satisfy the function of transit
(l)At least need train, city bus, short distant bus, and rapid transit terminal.
(?)create a convienent connection for transfer.
(Strain station :
to provide a pleasure space for transfer, despersion and waiting.
to provide a major access for the passenger to connect with outside street systerm.
station design must match the new rapid transit systerm (under structure).
(d)bus station :
Reducing the types of transportation by moving the exsiting long distant servce to Sin-Ye sub-urban core.
redesign the existing bus station and adapt to the block newal.
sperate the different scale of bus, road and parking lot.
(5)city bus :
reconsider the position of existing bus stops.

create a certain route and parking lot for city bus.
create a waiting space along plaza and connected with pedestry.
(6) New rapid transit systerm
(figure )
below the ground level 45 ft.
use the same facilities with train station.
main entry of terminal should be connected with pedestry.
keep the shortest walking distant with other facilities.
(7) passengers cars and taxi :
to design a certain ai*ea for passengers parking.
to limit the time for taxis' staying.
to limit the pass-through circulation.
2. Reinforce the landuse
(1) provide a suitable public facilities.
(2) commercial building can increase the lane value.
3. Eastablish a easy circulation systerm.
(1) The circulation land used is the first considerlation.
(2) prevent directing uneed transportation into this area.
(3) seperate the cars and pedestrian.
(4) perimeter circulation systerm.

(5)Bus station and train station: The activities of study area are most effected by the cars and passengers. Their be havior model are :


1. Land use (1)existing :
a. area : 38 A.C.
b. commerical, transnortation.
* retail mixed-use
* commerical : 6.0 A.C.
* transportation (station, road, parking) : 20 A.C.
* open space : 10 A.C.
(2)goal of city (after renewal) :
a. area : 38 A.C.
b. commerical, transportation, retail mixed-use.
c. commerial I :
* F.A.R. : 360%
* open space : 40%
(4)the ratio of commercial, transportation ratail are flexible, but transportation is the first consideration.

2. Circulation (l)existing :
a. train : 10.6 (unit : million persons/day)
b. other transportation : 3?
