Understanding urban spatial pattern of land use is great significance to management and resource allocation. Urban space has strong heterogeneity, thus there were many researches focusing on the identification use. The emergence multiple new types geospatial data provide an opportunity investigate methods mapping essential popularization street view images represented by Baidu Maps benificial rapid acquisition high-precision data, which attracted attention scholars in field research. In this...

Capacity is an important design parameter for roundabouts, and it the premise of computing their delay queue. Roundabout capacity has been studied decades, empirical regression model gap-acceptance are two main methods to predict it. Based on theory, by considering effect limited priority, especially relationship between priority factor critical gap, a modified was built roundabout capacity. We then compare results Raff’s method maximum likelihood estimation (MLE) method, MLE used gaps....
