Reported as one of the most visited top attractions in Taiwan, night markets are well-recognized for their diversity and very distinctive service model. After regular working hours have finished, these multiform commercial clusters emerge as an essential component of cities’ urban fabrics. Many researchers have previously studied the walkable environment and physical activities in alternative study cases located in historical districts such as in the case of Kuala Lumpur, Malaysia (Mansouri & Ujang, 2017), but very few have demonstrated the alteration in the space usage and the transformation suffered on street networks related to commercial zones after their reshaping caused by such informal business. This research has been conducted in a night market located in Taipei City, which is Taiwan’s major urban centre and its most multicultural hub.

Understanding these unique commercial zones has appeared as a very important research topic within multiple disciplines. It also contributes to visualize vendors’ business dynamics are directly affected by the perception that visitors visualize based on their experience. Therefore, learning about night markets’ dynamics enhances (in different ways and professional fields) the improvement of the spatial experience regarding user-centered design and it promotes the venue as a worth visiting destination. This research initial results are certainly valuable contribution for a smart city approach with the integration of computational simulation and user-centered design.
