Traffic Calming in Historic District Conservation

The Historic Conservation District(HCD) is an important target for urban heritage protection in China. The spatial characteristics of its road system,formed before the appearance of automobile,do not adapt to the car traffic. In the context of very rapid motorization in Chinese cities,the increase in car traffic brings an inevitable trouble for the protection of HCDs. Road widening and pedestrianization are two popular solutions to this problem in current practices; however,both of them may lead to negative consequences. Inspired by the development of Zone 30 in European cities,this paper firstly cleared up first some misunderstandings of the concept of traffic calming,then taking the inner city of Paris as an example,explained how traffic calming measures can be implemented in HCDs and what effects will be generated. Finally,it discussed the possible application of traffic calming measures in HCDs projects in China and pointed out the specific situations of Chinese cities to which the planners should pay more attention.

Urban built heritage protection and realistic dilemmas:the development process,protection system,and critical thinking of historic districts in Dalian

In China,the northeastern region has preserved many valuable modern built heritage buildings,which are undergoing difficult exploratory protection during the industrial and urbanisation process.Taking Dalian city as a case study,this article retraces the history of Dalian’s opening up and colonial management from the perspective of urban planning and historic district protection and management systems.This article sorts out the influence of national and local institutional policies on Dalian’s urban construction and development to analyse the past evolution,current problems and internal causes of the renovation and protection of Dalian’s typical historic districts.This influence is mainly reflected in the lack of protection and damage done to unofficial heritage,the disconnection between historic districts and the surrounding environments and urban textures,and the Chinese-style transformation and economic decline of exotic areas.This paper calls for attention to and the rapid clarification of the built heritage list,the improvement of planning and protection systems and related supporting policies,and a focus on the protection of the authenticity of colonial heritage.This paper provides strategic guidance for improving the protection of historic districts in Dalian in Northeast China and hopes to serve as a reference for the protection of built heritage in other nonfamous historic and cultural cities.

Unveiling the potential of space syntax approach for revitalizing historic urban areas:A case study of Yushan Historic District,China

Historic urban areas are a crucial component of urban heritage,embodying the collective memory of urban development and possessing distinctive urban textures and cultural attributes.However,the growing impact of globalization on the urban environment poses challenges to historic urban areas,including diminishing social recognition,aging infrastructure,loss of vitality,and cultural erosion.To address these challenges,this study proposes a novel approach to revitalizing historic urban areas by employing space syntax methodology.The study focuses on Yushan Historic District in China as a case study and uses spatial models within space syntax to describe,analyze,and interpret its urban morphology.The objective is to enhance urban vitality while preserving the heritage fabric of historic urban areas.Additionally,it aims to contribute to the advancement of space syntax research,specifically in the context of urban renewal and revitalization of historic districts.The findings reveal the spatial factors that contribute to the generation of vitality within the district,identify areas requiring intervention,and provide strategies for revitalizing historic urban areas.This study demonstrates the potential of utilizing a space syntax approach in urban revitalization,providing valuable guidance for effectively conserving urban heritage within the context of urban renewal.

Characteristics of road network forms in historic districts of Japan

This study focused on the structure and the platform of the road space of historic districts. We analyzed the road networks of 16 historic districts in Japan from the perspectives of circularity, accessibility and indirection based on graph theory. By calculatin8 and comparing the indexes of each road network （NW1 and NW2） forms, we quantitatively describe the effects of the main prefectural roads （more than 4 m in width） and narrow streets （less than 4 m in width） on the spatial characteristics. And it turned out that we could divided the 16 objective historic districts into 4 types. Moreover, we qualitatively studied the characteristics of each type of historic districts based on their development background and the structure of road network.

Urban Conservation Through Chinese Local Original Architecture:The Preservation and Renovation of Zhongshan Road in Hangzhou

How to realise the goal of city revival through the preservation of historic districts is an important issue for all historic cities.This article introduces the Preservation and Renovation Project of Zhongshan Road in Hangzhou regarding its guiding principles,design concepts,and the entire construction process.In this project,the existing historical buildings along Zhongshan Road were preserved by keeping the remains of different historical periods and various lifestyles of the inhabitants.Rather than merely refurbishing the street front only,we reconstructed the Southern Song Dynasty city-block walls along Zhongshan Road and restored the Fangxiang city fabric to create the streetscape of the former Imperial Avenue.Afforested terraced teahouses were built along the road,and the original water system was restored so as to realise the atmosphere of‘watertown’.New buildings were added by adopting local materials and vernacular building forms.The article summarises two strategies for the preservation of a historic district in a large city.One is the comprehensive project planning by research and investigation.The other is the overall design guideline for the street blocks.It also reflects on the disappointing aspects that mainly resulted from time limitations and the poor taste in the refurbishment of shop houses.

Successes and failures of participation-in-design： Cases from Old Havana, Cuba

Following the fall of the Soviet Union, Cuba faced a crisis that forced it to change its housing approach. Self-help building programs began to supplant the construction of mass standardized housing estates. The Community Architect Program was developed to provide design advice to self-help builders, and it expanded exponentially within a decade. By the year 2000, all municipalities across Cuba had their own Community Architect Office. White the approach of the Community Architect Program has been hailed a breakthrough in the fields of planning and architecture, the particular case of Old Havana suggests that several obstacles prevent residents from benefiting from its services. The author identifies the strengths and limitations of the approach by looking at two home renovation projects in Old Havana and the perceptions of tow-income residents on the work done by community architects. This research indicates that participatory design methods should be complemented by community-based initiatives that address other aspects of the housing development process, such as access to materials, construction, and construction management.

Preservation and Regeneration Strategies for the Wudadao (Five Avenues) Area, Tianjin, China

Nowadays, Tianjin becomes a major economic development zone, emulating operations seen in Shenzhen and Shanghai. But the corresponding large-scale urban development is bringing great challenges to the existing modern architectural heritage, which is an indispensable part of Tianjin's history, character, and culture. The Wudadao Area in the previous British Concession is such a case. Through examining its development process, this research identif ies four modes of preservation strategies, and analyses the respective characteristics. Multiple stakeholders who take part in Wudadao's preservation and regeneration are recognized. Via case studies, the research elucidates the different roles played by responsible departments in Tianjin Municipal Government, state-owned enterprises, and local residents respectively. In a micro-circulation way, Wudadao has developed from an endangered colonial settlement to a re-recognized symbol of Tianjin's urban culture and a refurbished showcase of global identity.

历史文化街区更新实施中的社区信任建构--以北京史家胡同为例

Concerning the complexity and diversity of demands in historic and cultural districts,the protection and regeneration planning(PRP)practice has been gradually shifted from spatial design to pluralistic and participatory community governance.Previous studies have pointed out that community trust is an essential means to eliminate social resistance and improve community cohesion and executive capability.However,the trustbuilding mechanism has been given little attention in urban planning.This study intends to improve the theoretical cognition of trust in community governance and provide suggestions for addressing issues of protection and regeneration planning in historic and cultural districts.With Shijia Hutong in Dongcheng District of Beijing,as an empirical case,this paper conducts a household survey and applies the Structural Equation Model(SEM)to explore the influencing elements and community trust-building path in the protection and regeneration planning from the perspective of residents.Through analyzing the influencing mechanism of residents’perception,it reveals that,firstly,pluralistic governance that is composed of the grass-roots government,NGOs,and residents can directly promote residents’perception of the protection and regeneration planning,and have a greater influence by facilitating public participation in building up community trust.Secondly,residents’perception of the protection and regeneration planning would not be improved if public participation failed to build up community trust.Thirdly,community trust consists of neighborhood trust and leadership trust,of which the latter is more important.These findings contribute a new perspective and solution to urban regeneration and heritage protection in the future.In addition,this study may inspire research on trust-building through urban planning,governance,and public participation.
