Research on walking design strategies of university campus：taking the Siping Road campus of Tongji University as an example

Since the 21st century, with the expansion of the university, the campus construction has flourished, and the contradiction between the campus and the people has become increasingly intensified. In 2017, Tongji University Siping Road Campus ushered in the transformation of “car-free campus” and explored the development of campus walking, but at the same time there was some controversy. This paper attempts to explore the optimization design of the traffic organization, walking environment and node space of the reconstructed campus. Firstly, based on the current situation research and questionnaire interviews, we found the design of the walking environment in the current site. Secondly, we draw on the relevant successful cases, put forward the design principles, and finally respond to these problems with the walking strategy of Tongji University and the design strategy of the nodes. The design strategy is divided into the following three levels: I. The overall optimizing strategy on Siping Campus First, reorganize the three lines of campus planning, including the car loop, visit the tour line and the runway to make it more complete and easy to use. Secondly, from the design and management, it advocates the priority of walking on the campus, and increases the speed of controlling the travel speed of motor vehicles and non-motor vehicles to ensure the safety of pedestrians. In addition, under the updated traffic organization, the management and parking order will be rearranged and refined to provide more space for walking. Ⅱ.The environmental improvement strategy of the pedestrian area Focus on solving the contradiction between people and bicycles in the key areas of walking. Moderately separate walking and non-motor vehicles, implement time-sharing management, and solve the problem of peak congestion. Redesign the public space according to the needs of the event, fully stimulate the vitality of the public space, and exert the road efficiency. Adjust road flatness and lighting layout to enhance the safety and comfort of the walking environment. III. The detailed design strategy of important nodes Select the important nodes where the contradiction between people and vehicles is concentrated to deepen the design. On the one hand, it implements tranquillity measures on the road sections, slows down the speed of bicycles, and realizes the separation of people and vehicles during peak hours. On the other hand, a two-story corridor is set up between the dining hall and the south building to increase the walking space and provide a place for daily rest. At the same time, it creates a gray space for shading and rain protection under the corridor, creating a more convenient and comfortable outdoor environment for teachers and students. . Inspired by the “car-free campus” project of Tongji University, I started this research on the basis of the personal experience. Through a one-year study tour in Europe, some practical cases of pedestrian environment strategies in Europe are shown in this article. It is hoped that this research and design paper will contribute to the establishment of the theoretical system of " walking campus ".
