The present invention discloses an urban traffic velocity estimation method based on multi-source crowd sensing data. This method, based on roadside pedestrian data and road navigation data collected by smart phones, obtains a final estimated velocity through the steps of missing data filling, self-view velocity aggregation and multi-view velocity fusion. This fine-grained large-scale urban traffic velocity estimation method can achieve velocity estimation on all types of roads, including suburban road sections and paths, instead of just focusing on main roads in a city center. According to the present invention, based on data driving, the urban traffic velocity estimation method does not need to install additional devices on roads, and is low in cost and high in universality. Compared with the prior art, the urban traffic velocity estimation method has higher practicability, theoretical property and applicability, and is of great significance for improving traffic management and planning.

The application discloses a kind of center area non-regular living space full-time simulation optimization method based on multi-agent, including full-time non-regular living space space-time behavior information data acquisition and pre-processing, city center area non-regular living space function identification and index extraction, non-regular living space function-oriented differentiated weight evaluation system construction, non-regular living space inefficient area identification, full-time non-regular living space multi-agent model construction, non-regular living space optimization simulation based on multi-agent and non-regular living space optimization scheme visualization and intelligent control seven steps.The application realizes the intelligent perception and dynamic response of the behavior trajectory of people in non-regular living space in each period of the day, helps to promote the efficiency optimization and structure reasonable layout of non-regular living space in time dimension, improves the timeliness, accuracy and scientificity of planning scheme, and promotes the coordinated people's city construction in full-time.
