CURRENT TRAFFIC SITUATION IN CHAOYANG DISTRICT

Traffic Flow

Bicycle movements at the eight main traffic entrances and exits of the site were counted at fixed points of observation and further estimated to obtain a plot of traffic flow versus time within the site over a 24-hour period. Compared to weekdays, there is only one peak in the traffic volume fold on rest days and the total volume is lower than that of weekdays.

Site Problem

Site problems can be divided into four main categories. Firstly, there are unsafe phenomena such as contraflow, miscellaneous lanes and space encroachment; secondly, lack of parking space, lack of signage and other inconvenient cycling problems exist; thirdly, cycling is not comfortable enough, some roads are of poor quality and shade is not available; fourthly, the design of some sections does not meet the standards of green design and private cars are still heavily used.

Shanghai's rapidly urbanizing city has a high density of viaducts, which in many areas have a fragmented relationship with the surrounding space, resulting in the emergence of many non-places, whereas before this, citizens were more active in the use of the overhead space, such as installing billboards, drying clothes, and making decorations.

The site selected for this project is located along Shanghai's rail line 3, and the scope includes three subway stations. The elevated ground level in this site is too close to the surrounding buildings, affecting the surrounding sense of place in several dimensions such as sound, light and landscape. The residential nature of the land along the line is dominant, but there are few users walking or loitering within the site, and the excessive sunlight during the day and dim streetlights at night contribute to this phenomenon.

SECTION | REDISTRIBUTION OF LIGHT

The design attempts to improve the fragmented relationship between the viaduct and the surrounding space by means of a curved roof. This newly added element transforms the original hard space separated by concrete columns into a soft activity space, and completes the transformation process from non-place to some-place through the functional implantation of the reshaped space.

During the day time, the upper layer of the curved roof is used to refract the direct sunlight into diffuse light to reduce the temperature under the bridge and create a more suitable environment for activities; during the night time, the lower layer of the curved roof is used to convert the energy stored during the day into light energy with built-in solar panels to connect with the surrounding buildings and improve the insecurity of the site.

Scenes

Through the introduction of the curved roof element, the original non-place environment will be improved and functional and landscape will be introduced.

The scope of the design will be collaborated with the surrounding neighborhood and campus, and the users of the site will also participate in the renovation process by voting or designing themselves.

The Cultural Heritage Of 1865 Industry Park

The earliest record of a building on the site dates back to the construction of Kenchuji Temple in 240 AD, and the site was used as a Buddhist site from then until 1865. After the outbreak of the First World War, Li Hongzhang built the site as a factory for the production of gunpowder and weapons. Two very different and even conflicting cultures coexisted on the same site: war and peace, death and life, killing and mercy.

Update Strategy

In order to better connect the cultural and physical spaces, the two conflicting cultural elements of the site (industry and Buddhism) are relinked with the physical spaces to create three new spaces: business, toursim and landscape. This also separates the corresponding users to avoid negative influences between them.

Layered Illustration

The original material elements of the site are distributed in a haphazard manner, and the fit with the cultural elements is low. The three types of spaces are opened up through the operation of walkways, corridors and building combinations, and then functional implantation is carried out according to the needs of the corresponding user groups.
