Research On The Optimization Strategy Of Slow Traffic System In Suzhou Old City Rail Transit Station Area

Suzhou is one of the first batch of national historical and cultural cities,and it is also the second batch of national transit cities to create cities.Due to the strong centrality of the ancient city of Suzhou,residents’ daily commuting,daily life traffic,and foreign tourist traffic are intertwined here.The traffic carrying capacity of the ancient city’s roads tends to be saturated,and public transportation,pedestrian,and non-motorized vehicle traffic account for about 66%.In recent years,the construction of rail transit stations in the ancient city has accelerated.The coverage rate of rail transit stations in the ancient city has reached approximately 75%,and the proportion of rail transit trips has increased significantly."Rail transit + slow travel" has become the main mode of transportation in the ancient city,but the road space in the ancient city is limited and slow.The travel space is limited,and it is necessary to study and discuss the optimization strategy of the slow travel system in the area of the Suzhou ancient city rail transit station.The research is based on combing the related theories and documents of the slowmoving system in the ancient city rail transit station area,combing and summarizing the components and contents of the slow-moving system in the rail transit station area,analyzing and summarizing the current situation of the slow-moving path,network,and slow-moving facilities in the ancient city station area,The characteristics and problems of the slowmoving environment,the influencing factors of the slow-moving system in the area of the Suzhou ancient city rail transit station area are analyzed from the station level,the ancient city level and the behavioral activity demand level.It is proposed that the ancient city slow traffic system based on the rail transit-based transportation organization should be built at the height of the overall protection and development of the ancient city and the construction of a transit city.Including starting from the transportation organization,the pedestrian and bicycle road network in the rail transit station area,the conventional bus line network,and the pedestrian and bicycle road network in the bus station area jointly constitute the slow travel of the ancient city "rail transit + slow travel" mode The line network,and the slow-moving system for daily commuting,cultural tourism,commercial shopping,commuting to school,fitness and leisure,and medical treatment,which are six main slow-moving activities.The optimization of the slow-moving system at the station level should be carried out from three levels: the TOD mode of the station,the optimization of the slow-moving spatial structure in the station area,and the improvement of the slow-moving environment and facilities.Propose three types of TOD models and optimization measures for Suzhou Old City Rail Transit Stations: layout along roads,patch layouts,and open space types;based on the development positioning of the station area,it will focus on cultural exhibitions,cultural and creative districts,and tourist windows.Optimize the slow-moving space structure of the8 types of stations,historical blocks,traditional commercial centers,modern high-end commercial,cultural,educational and academic,and ecological residential areas;under the principle of slow-moving priority,sub-arterial roads,branch roads,and street areas are optimized.Optimize the design of the three types of road sections of lanes;propose the implementation of parking zoning strategies for the road occupation of non-machine parking;optimize the street environment of the three types of slow paths for tourism,fitness,and shopping.
