The purpose of this experiment was to determine whether a specifically worded prompting sign ("BEGIN SLOWING HERE") could reduce speeding where a highway entered an urban area with a residential speed limit. Speed measurements were obtained on vehicles at the start of the residential speed limit zone. Following a baseline period the prompting sign was introduced, removed and reintroduced. The results indicated that the prompting sign produced clear reductions in the percentage of motorists travelling 10, 15 and 20 km or more over the speed limit. These results suggest the importance of more specific road signs in influencing the behavior of motorists.
本实验的目的是确定一个措辞特定的提示标志（“从此处开始减速”）是否能在高速公路驶入设有住宅限速的市区时降低车速。在住宅限速区起点对车辆进行速度测量。在基线期之后，引入提示标志，然后移除，之后再次引入。结果表明，提示标志使超过限速10公里、15公里及以上或20公里及以上行驶的驾车者百分比明显下降。这些结果表明更具针对性的道路标志对于影响驾车者行为的重要性。
