Abstract

Although China has the longest and widest range of tactile paving surfaces in the world, we hardly see people with visual impairments on city streets. A main reason may be the poor state of these tactile paving surfaces. In this study, we evaluate the effectiveness of tactile paving surfaces in Changsha city by measuring their covering capacity and connectivity. We first collect the obstruction data with smart phones. Then, the obstruction data are transformed and matched with road networks. Tactile paving surface networks are constructed later. Finally, the shortest distances between public service facilities and tactile paving surface networks are analysed, and several indicators are calculated to measure the connectivity of the tactile paving surface networks. The results show that the state of tactile paving is worse than it should be, thus leading to poor effectiveness of the tactile paving surfaces.
