At intersections, drivers need to infer which ways are allowed by interpreting mandatory and/or prohibitory traffic signs. Time and accuracy in this decision-making process are crucial factors to avoid accidents. Previous studies show that integrating information from prohibitory signs is generally more difficult than from mandatory signs. In Study 1, we compare combined redundant signalling conditions to simple sign conditions at three-way intersections. In Study 2, we carried out a survey among professionals responsible for signposting to test whether common practices are consistent with experimental research. In Study 1, an experimental task was applied (=24), and in Study 2, the survey response rate was 17%. These included the main cities in Spain such as Madrid and Barcelona. Study 1 showed that inferences with mandatory signs are faster than those with prohibitory signs, and redundant information is an improvement only on prohibitory signs. In Study 2, prohibitory signs were those most frequently chosen by professionals responsible for signposting. In conclusion, the most used signs, according to the laboratory study, were not the best ones for signposting because the faster responses were obtained for mandatory signs, and in second place for redundant signs.
在十字路口，驾驶员需要通过解读强制性和/或禁止性交通标志来推断哪些方向是允许通行的。这一决策过程中的时间和准确性是避免事故的关键因素。先前的研究表明，整合来自禁止性标志的信息通常比整合来自强制性标志的信息更困难。在研究1中，我们在三岔路口将组合冗余信号条件与简单标志条件进行了比较。在研究2中，我们对负责路标设置的专业人员进行了一项调查，以测试常见做法是否与实验研究一致。在研究1中，应用了一项实验任务（n = 24），在研究2中，调查回复率为17%。这些城市包括西班牙的主要城市，如马德里和巴塞罗那。研究1表明，使用强制性标志进行推理比使用禁止性标志更快，并且冗余信息仅对禁止性标志有改善作用。在研究2中，禁止性标志是负责路标设置的专业人员最常选择的标志。总之，根据实验室研究，最常用的标志并非路标设置的最佳选择，因为强制性标志的反应速度更快，其次是冗余标志。
