## 1 Introduction  
Among the components of urban planning, built environments implicitly guide people's travel habits. Built environments have a \"lock-down effect\" on residents' travel behaviors [1], as travel behaviors are determined by the spatial structure and functional layout of built environments at the macro level. Therefore, optimization of a built environment is regarded as an important means to shape a low-carbon urban spatial structure, guiding the green and low-carbon travel patterns of residents and combatting climate change issues. Urban renewal provides opportunities for traffic improvement, accelerating the pace of its progress and optimizing land use and the urban layout structure. Furthermore, urban renewal and traffic improvements can promote one another, interacting as both cause and effect. It must be carried out scientifically and orderly, under the control of traffic planning. As an important factor of urban renewal in the sustainable direction of urban development, transportation must be given sufficient attention. Therefore, it is necessary to clarify the impact of different components of built environments on travel behaviors in the context of urban renewal. China is one of the largest countries experiencing large-scale urban renewal. In many areas of the country, especially large- and medium-sized cities undergoing accelerated urbanization, the need for the renewal and regeneration of \"urban villages\" is particularly urgent, being critical targets. As informal residential communities, urban villages show many inconsistencies with the development of cities. The traditional renewal of urban villages often adopts demolition and reconstruction methods, which play important roles in improving land-use efficiency and promoting sustainable urban development [2; 3]. However, as low-cost living spaces, urban villages accommodate a large number of urban employment and emigration populations from high-housing-cost areas, which improves the flexibility of urban development. At the same time, the high-density population of urban villages has relieved the trend of the job-housing imbalance and, hence, reduced the overall transportation cost of cities. Therefore, urban villages hold the position of a double-edged sword, and the issue of urban villages cannot be solved solely through demolition. Currently, differentiated and diversified renewal strategies are being developed, and the proportion of urban village demolishment and reconstruction is gradually becoming lower, which encourages the comprehensive renovation and functional regeneration of urban villages to promote organic and effective urban renewal. Therefore, under these circumstances, new questions are arising in research relating to the relationship between travel behaviors and built environments. Although many related studies have been conducted in the context of developed societies, the situation in China is not understood sufficiently. Thus far, there is little research on the interaction between urban village and traffic structure optimization, especially regarding built environment characteristics, resident travel characteristics, and the relationship between built environments and resident travel behaviors involved in the process of urban village renewal. China has witnessed unprecedented urban development and regeneration over the past few decades. The regeneration in residential built environments and neighborhood type have resulted in changes to jobs-housing relationships and, ultimately, daily travel demands, providing an important context for studies of built environments and travel behaviors in urban China. In view of this, this research attempted to conduct theoretical analysis and empirical research on the effects of the built environment on travel behaviors in the context of urban village reconstruction in China to explore the relationship between built environment and travel behaviors.
