Through the exploration of “slow traffic space” and its design concept and strategy theory, the problem of slow traffic space is sorted out from the aspects of policy background, spatial form and cultural construction, with Lugu Street as an example. Based on the unique cultural resources in the district, the optimization strategies are proposed from the aspects of spatial form improvement, unsupervised technology utilization, enhancement of residents’ willingness to slowly traffic and Winter Olympics culture shaping. In addition, a slow traffic space improvement scheme with easy implementation, convenient access and rich connotation is formed, in order to provide new methods and ideas for improving the quality of slow traffic space.展开更多

These models can reproduce some realistic phenomena which are absent in the original NS model. But in these models, the size of cluster is still not considered as a useful parameter. In real traffic, the slow-to-start motion of a standing vehicle often depends on the degree of congestion which can be measured by the clusters＇ size. According to this idea, we propose a cluster-size dependent slow-to-start model based on the speed- dependent slow-to-start rule （VDR） model. It gives expected results through simulations. Comparing with the VDR model, our new model has a better traffic efficiency and shows richer complex characters.展开更多
