利用新近发展起来的人车冲突分析(PVCA)方法，对按照共享空间原则重新设计的城市街道人车交通冲突变化进行了研究。在第一步中，对PVCA方法进行了修订，以更准确地反映共享空间的特点；这一修订一方面包括确定冲突发生的系统程序，另一方面全面量化冲突严重程度分级程序。然后，将改进的PVCA方法应用于伦敦的一个案例研究，视频数据来自展览道遗址重新开发前后的几个时期，从传统的双车道转变为具有一些共享空间元素的现代设计。比较分析的结果表明，由于重新设计，交通冲突率普遍下降，但也突出了可能需要进一步分析的具体问题。
Changes in pedestrian–vehicle traffic conflicts in urban streets redesigned according to the principles of shared space were investigated with a recently developed pedestrian–vehicle conflict analysis (PVCA) method. In a first step, the PVCA method was revised to reflect more accurately the features of shared space; this revision included the definition of a systematic process for identifying conflict occurrences on the one hand and the full quantification of the conflict severity grading process on the other. Then the refined PVCA method was applied to a case study in London with video data from periods before and after the redevelopment of the Exhibition Road site from a conventional dual carriageway to a modern design with some elements of shared space. The results of the comparative analysis indicated a general decrease in traffic conflict rates as a result of the redesign but also highlighted specific issues that may require additional analysis.
