Abstract The urban residential unit is intimately related to people's life, and the traffic environment of a
residential unit constitutes a key standard for the environment assessment of the unit. The spatial resolution of
the high-resolution remote sensing image makes it possible to study the traffic environment on the scale of the
urban residential unit. According to characteristics of the high-resolution image, a multi-level index system for
the assessment of traffic environment of urban residential units was constructed, which took into account the
traffic environment and road accessibility. In this paper 50 representative urban residential units in Xiamen City
were chosen and all the indices mentioned above were computed and further analyzed. The results indicate that the
utilization of the high resolution image for the assessment of city traffic environment quality is an economical,
simple and feasible method.
